All I need is the answer please and thank you

Step-by-step explanation:

The equation 3x + y = 0 can be rearranged to y = -3x. This means that the graph of the equation is a straight line with slope -3 and y-intercept of 0.

The three points that are in the solution set are (-2,6), (-5,5), and (3,-9). Plotting these points on a coordinate plane and connecting them with a straight line, we can see that they all lie on the same line with slope -3:

[Graph not shown here, but a straight line with three points (-2, 6), (-5, 5), (3, -9) can be plotted with a slope of -3 and y-intercept of 0.]

From the graph, we can see that the line passes through the origin (0,0), which means that the y-intercept is 0. The slope of the line is -3, which means that the line has a negative slope and is downward sloping. The line separates the plane into two half-planes, one above the line and one below the line. The points above the line have y-coordinates greater than 0 and the points below the line have y-coordinates less than 0.

Answer:

Farmer Bill sold 120 lb of potatoes

Step-by-step explanation:

Suppose farmer Bill had x lb of potatoes. He sold a quarter to the first person. A quarter is written as (1/4)x. After that, Bill had x-(1/4)x = (3/4)x.

Then he sold 4/9 of what was left to the second person, thus it was left 1-4/9=5/9 of the remaining potatoes. Multiplying both factors:

\(\frac{5}{9}*\frac{3}{4}x=\frac{5}{12}x\)

This is the remaining portion of the potatoes.

Finally, he sold 4/5 of it and the last 10 lb. This means 1 - 4/5 = 1/5 of the remaining is equivalent to 10 lb:

\(\frac{1}{5}*\frac{5}{12}x=\frac{1}{12}x\)

Thus:

\(\frac{1}{12}x=10\)

x = 120 lb

Farmer Bill sold 120 lb of potatoes

The Farmer will sold 120 lb of potatoes.

Let us consider that farmer have x lb of potatoes.

He sold a quarter to the first person, that is  \(\frac{x}{4}\)

Potatoes left,\(=x-\frac{x}{4} =\frac{3x}{4}\)

4/9 of what was left to the second person,

 Potatoes sell to second person is, \(\frac{3x}{4} *\frac{4}{9} =\frac{x}{3}\)

the third buyer bought 4/5 of what was left

       that is,          \(\frac{4}{5}*(\frac{3x}{4} -\frac{x}{3} ) =\frac{x}{3}\)

Potatoes left \(=\frac{5x}{12} -\frac{x}{3} =\frac{x}{12}\)

Since, Potatoes left = 10 lb

So,   \(\frac{x}{12} =10\\\\x=12*10=120\)

Thus, The Farmer will sold 120 lb of potatoes.

Complete question :

A coin is tossed and a die is rolled. Find the probability of tossing a tail and then rolling a number greater than 2.

Answer : 1/3

Step-by-step explanation:

For a coin :

Sample space = (T, H)

Probability = required outcome / Total possible outcomes

Probability of tail, p(T) = 1 / 2 = 0.5

For a fair die:

Sample space = (1, 2, 3, 4, 5, 6)

Required outcome = number greater than 2 = (3, 4, 5, 6) = 4

P(number greater than 2) = 4/6 = 2/ 3

Hence, probability of a tail, then a number greater than 2 :

(1/2 * 2/3) = 2 /6 = 1/3

Floyd needs 33 matches to make a rectangle with a length of 20 matches.

To find out how many matches Floyd needs to make a rectangle with a length of 20 matches, we can observe a pattern in the given information.

From the given data, we can see that as the length of the rectangle increases by 4 matches, the number of matches used increases by 8. This means that for every additional 4 matches in length, Floyd requires 8 more matches.

Using this pattern, we can calculate the number of matches needed for a rectangle with a length of 20 matches.

First, we need to determine the number of 4-match increments in the length of 20 matches. We can do this by subtracting the starting length of 3 matches from the target length of 20 matches, which gives us 20 - 3 = 17.

Next, we divide the number of 4-match increments by 4 to determine how many times Floyd needs to add 4 matches. In this case, 17 ÷ 4 = 4 with a remainder of 1.

Since Floyd requires 8 matches for each 4-match increment, we multiply the number of increments by 8, which gives us 4 × 8 = 32 matches.

Finally, we add the remaining matches (1 match in this case) to the total, resulting in 32 + 1 = 33 matches needed to reach a length of 20 matches.

\((-4.89, 3)\) and \((4.89, 3)\) are the farthest from the origin and \((0, -1)\) is the closest from the origin.

Let be a curve of the form \(x^{2}+3\cdot (y-2)^{2} = 27\). The distance with respect to origin is found by using the following Pythagorean identity:

\(r = x^{2}+y^{2}\) (1)

Where \(r\) is the square distance function.

We can modify (1) as following:

\(r = [27-3\cdot (y-2)^{2}]+y^{2}\)

\(r = 27-3\cdot (y^{2}-4\cdot y +4)+y^{2}\)

\(r = 27-3\cdot y^{2}+12\cdot y -12 + y^{2}\)

\(r = -2\cdot y^{2}+12\cdot y+27\) (1b)

Now we apply the First and second derivative tests to determine the minimum and maximum distances from the origin:

First derivative test

\(-4\cdot y +12 = 0\)

\(y = 3\)

Second derivative test

\(r'' = -4\)

The y-component represents a maximum.

Now we graph the function with the ressource of a graphing tool, we find the following points:

Farthest points: \((-4.89, 3)\), \((4.89, 3)\).

Closest points: \((0, -1)\).

\((-4.89, 3)\) and \((4.89, 3)\) are the farthest from the origin and \((0, -1)\) is the closest from the origin.

Answer:

x=2

Step-by-step explanation:

10 - (x + 3) = 5

To solve for x, we can start by simplifying the left side of the equation:

10 - (x + 3) = 5

10 - x - 3 = 5

7 - x = 5

Next, we can isolate x on one side of the equation by subtracting 7 from both sides:

7 - x = 5

7 - x - 7 = 5 - 7

-x = -2

Finally, we can solve for x by dividing both sides of the equation by -1:

-x = -2

x = 2

Therefore, the solution to the equation is x = 2.

Assume that the basis for a subspace V in Rn is v1,..., vp. Show that a vector in Rn is orthogonal to a vector in V if and only if it is orthogonal to every vector v1,..., vp.

An orthogonal vector , In mathematics, orthogonality is an extension of perpendicularity, particularly in vector calculus and linear algebra. Basic geometry dictates that two lines or line segments are only perpendicular if they form a straight angle.

It makes sense to think of vectors as arrows, such as R 2 and R 3, when discussing orthogonal vectors in an inner product space (a real or complex vector space with a notion of vector multiplication).

There are inner product spaces where it makes no sense to conceive of vectors as arrows, yet one still needs to have some understanding of what it means when discussing orthogonal vs. perpendicular.

Hence, It is orthogonal to every vector in vector space, or o V. Every vector in V is a linear combination of these vectors since v1,..., vp serves as the basis for V.

Answer:

Step-by-step explanation:

The month of June has  40 sweets

Let the number of sweets in the month of June be  P

Given that April,  May and June collectively have 90 sweets

Given that May has three quarters of number of sweets as that of June

So we can write

\(\rm Number\; of \; sweets\; in \; May = \dfrac{3P}{4 } .......(1) \\\)

Similarly it is given that April has two third of sweets as that of May month and hence we can write

\(\rm Number\; of\; sweets \; in \; April = \dfrac{2}{3} \times \dfrac{3P}{4} = P/2 ......(2)\\\)

As the total number of sweets in  April,  May and June is  90

Let the number of sweets in  May be "M" and in April be "A"

We can write the following equation and solve it further

\(\rm M + A + P = 90\\From \;equations \; (1) \; and \; (2) \\\)

\(\rm P + 3P/4 + P/2= 90\\\\2.25 \; P = 90\\P = 40\)

So we can conclude that the month of June has  40 sweets
