Answer:
The Last box. (y=1/2x-4)
Step-by-step explanation:
The formula is y=mx+b
b is the interception point on the y axis.
So the -4 is where the line crosses on the y axis.
mx is how many spaces it goes up or down.
If you look the box goes up or down twice then left or right once.
So that's your answer, hope this helps.

if(x) = x4 - 6x2 +3 Find the intervals where f is concave up and where it is concave down. Locate all inflection points. (You may write on the next page if you need more space for this question.)
Answers
You have the following function:
\(f(x)=x^4-6x^2+3\)In order to determine the intervals, it is necessary to calculate the first derivative of the function, equal it to zero, and identify the zeros of the equation, just as follow:
\(\begin{gathered} f^{\prime}(x)=4x^3-12x=0 \\ 4x(x^2-3)=0 \end{gathered}\)the zeros of the previous equation are:
\(\begin{gathered} x_1=0 \\ x_2=\sqrt[]{3} \\ x_3=-\sqrt[]{3} \end{gathered}\)Next, it is necessry if the previous values are minima or maxima. Evaluate the second derivative for the previous values of x. If the result is greater than 0, then, it is a minimum. If the result is lower than zero, it is a maximum:
\(\begin{gathered} f^{\prime}^{\prime}(x)=12x^2-12 \\ f^{\prime}^{\prime}(0)=12(0)^2-12=-12<0 \\ f^{\prime}^{\prime}(\sqrt[]{3})=12(\sqrt[]{3})^2-12=24>0 \\ f^{\prime}^{\prime}(-\sqrt[]{3})=12(-\sqrt[]{3})^2-12=24>0 \end{gathered}\)Then, for x=0 there is a maximum, and for x=-√3 and x=√3 there is a minimum.
Hence, until x = -√3 the function decreases. In between x=-√3 and x=0 the function increases. In between x=0 and x=√3 the function decreases and from x=√3 the function increases.
Furthermore, it is necessary to find the inflection points. Equal the second derivative to zero and solve for x:
\(\begin{gathered} f^{\prime}^{\prime}(x)=12x^2-12=0 \\ x^2=1 \\ x=\pm1 \end{gathered}\)then for x=1 and x=-1 there are inflection points.
The interval where the function is concave up is:
(-∞ , -1) U (1, ∞)
The interval where the function is concave down is:
(-1,1)

When can we say that two triangles are similar?
Answers
The two triangles are similar If they have the same shape, but their sizes are different.
Similar triangles are triangles that have the same shape, but their sizes may be same or different. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion. The similarity of triangles are denoted by ‘~’ symbol
AA (or AAA) or Angle-Angle Similarity
If any two angles of a triangle are equal to any two angles of another triangle, then those two triangles are similar to each other.
SAS or Side-Angle-Side Similarity
If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed between those two sides in both the triangle are equal, then two triangles are said to be similar.
SSS or Side-Side-Side Similarity
If all the three sides of a triangle are in proportion to the three sides of another triangle, then the two triangles are similar.
Therefore, two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

Derive and explain an equation for the line of the form Y=m•x where M is a suitable number. In your explanation, attend to our definition of multiplication and explain why the equation holds for all points on the line (that have positive X and Y coordinates). B.) explain how to interpret M is the slope of the line. 
Answers
Answer:
a) y = 1.4x
b) 1.4, that is, any time x changes by 1, y changes by 1.4.
Step-by-step explanation:
A)
We want an equation in the following format:
y = mx
Point (5,7).
This means that when x = 5, y = 7. So
y = mx
7 = m*5
5m = 7
m = 7/5
m = 1.4
So the equation is:
y = 1.4x
B.) explain how to interpret M is the slope of the line.
The slope is how much y changes when x changes by 1.
In this case, it is 1.4, that is, any time x changes by 1, y changes by 1.4.

a number, y, is equal to twice the sum of a smaller number and 3. the larger number is also equal to 5 more than 3 times the smaller number. which equations represent the situation? 2 x minus y
Answers
The equations represent the given situation is:
2x - y = -6
3x - y = -5
where, x is the smaller number and y is the larger number.
Let the smaller number be x.
We have been given a number, y, is equal to twice the sum of a smaller number and 3
So, we get an equation,
y = 2(x + 3)
y = 2x + 6
2x - y = -6
The larger number is also equal to 5 more than 3 times the smaller number.
So, we get an equation,
y = 5 + 3x
3x - y = -5
Therefore, the equations represent the situation:
2x - y = -6
3x - y = -5

Answers
Answer:
Number of cars washed at the 6th hour = 12 cars
Sum of all cars washed in 6 hours = 42 cars
Step-by-step explanation:
First term, a = 2 cars
Common difference, d = 2 cars
6th term = a + 5d
= 2 + 5(2)
= 2 + 10
= 12 cars
Sum of the 6th term = n/2{2a + (n-1) d}
= 6/2{2*2 + (6-1)2}
= 3{4 + (5)2}
= 3{4 + 10}

(2 + √5)(2 + √5) (I didn't put the one on the conjugate for a reason; look above)
Step 1: Apply the distributive property by multiplying each term of 2 + √5 by 2 + √5
4 + 2√5 + 2√5 + (√5)²
Step 2: Combine 2√5 and 2√5 to get 4√5.
4 + 4√5 + (√5)²
Step 3: The square of √5 is 5.
4 + 4√5 + 5
Step 4: Add 4 and 5 to get 9.

When graphing the solution of an inequality on a number line, you will see either an open or closed circle and a part of the line shaded.
Part A:
Describe what an open circle represents and when you would use it.
Part B:
Describe what a closed circle represents and when you would use it.
Part C:
Describe what the shading on the number line represents.
Answers
Part A: An open circle on a number line represents an excluded value, indicating that the endpoint is not included in the solution set of the inequality. It is used when the inequality includes the symbols < (less than) or > (greater than), which denote strict inequality.
Part B: A closed circle on a number line represents an included value, indicating that the endpoint is part of the solution set of the inequality. It is used when the inequality includes the symbols ≤ (less than or equal to) or ≥ (greater than or equal to), which denote inclusive inequality.
Part C: The shading on the number line represents the range of values that satisfy the given inequality. It indicates which values make the inequality true. Typically, the shading is done to the right or left of the circle(s) depending on whether the inequality is greater than or less than.
Part A:
For example, if we have the inequality x > 2, we would represent it with an open circle at 2 on the number line. This means that 2 itself is not a valid solution, but any value greater than 2 is included.
Part B:
For example, if we have the inequality x ≥ -3, we would represent it with a closed circle at -3 on the number line. This means that -3 itself is a valid solution, as well as any value greater than or equal to -3.
Part C:
For example, if we have the inequality x > 2, we would shade the portion of the number line to the right of the open circle at 2. The shaded region represents all the values greater than 2 that satisfy the inequality. The shading visually illustrates the solution set and helps identify the range of valid values for the variable in the given inequality.

Answers
Betrys needs another 400 grams of diced potatoes to make her vegetable stew for 8 people.
How many more grams of diced potatoes she needs to make her vegetable stew for 8 people?
We know that Betrys is cooking for 8 people, and we know that a recipe for 2 people needs 10 ounces.
8 people is 4 times 2 people, then for 8 people you need 4 times 10 ounces, this is 4*10 oz = 40 ounces.
Now we can apply a change of units, remember that:
1 oz = 28 grams
Then the total amount she needs is:
40 oz = 40*28 g = 1,120 g
So she needs in total 1,120 grams, and in the balance, she already has 720 grams, so the amount that she needs is given by the subtraction:
1,120 g - 720g = 400
Betrys needs another 400 grams of diced potatoes to make her vegetable stew for 8 people.

y = - x - 6 is the equation of the parallel line.
Slope - Intercept Form:
A linear equation when graphed is a straight line that extends to infinity in both directions. One linear equation uses the slope, m, and the y - intercepts, c, in the form y = mx + c.
The equation of a line in 'slope - intercept form' is
y = mx + c (m is the slope and c the y - intercept)
y = -x is in he form with m = -1 and c = 0
note that parallel lines have equal slopes thus the partial equation is
y = -x + c
To find c substitute (-8 , 2) into parallel equation
2 = 8 + c
=> c = 2 - 8 = -6
Hence, y = - x - 6 is the equation of the parallel line.

An equilateral triangle in geometry is a triangle with equal-length sides on all three sides. In the well-known Euclidean space, an equilateral triangle also is equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others. It's also referred to it as a regular triangle because it is a regular polygon.
