Answer:
y = 5/2x + 5
Step-by-step explanation:
To find the equation, you first need to find the slope. You can do this by subtracting the two y coordinates (the two last numbers) and using that as the numerator (the top number of the fraction), and then subtracting the two x coordinates (the two first numbers) and using that as the denominator (the bottom number of the fraction). You then have the fraction -5/-2, which can be changed to 5/2 because they are both negative numbers. That is your slope. You then need to find the y-intercept (where the line connects with the y-axis). To do this, you need to figure out what the y (the second number) is when the x (the first number) is 0. In this example, you can already see with the second set of coordinates that the y-intercept is 5 because the x is 0. When this is not easily shown, you can figure out the y-intercept with a table. Sorry if I made it sound too complicated :)

A pink crayon is made with 12 mL, of red wax for every 5mL of white wax.
Which of the following wax mixtures will create the same shade of pink?
Choose 2 answers:
A
10 mL of red wax mixed with 24mL of white wax
B
48 mL of red wax mixed with 12mL of white wax
C
13mL of red wax mixed with 6mL of white wax
D

60mL of red wax mixed with 25mL of white wax
Answer:
Multiply 12 and 5 (by the same number) and add them to get whatever total ml of crayon wax is specified.
Ex: Total ml divided by 17, then find how many parts are red(12ml) and white(5ml)

20. The figures are similar. Find x.
Answer:
10
Step-by-step explanation:
You can see that both triangles are the same except for one thing: one is smaller. Since 7 is half of 14 and both triangles are similar, x stands for 10. That is because 10 is half of 20! :D
Answer:
X = 10
Step-by-step explanation:
The second figure is half of the first figure
14 divided by 2 = 7 and 20 divided by 2 = 10
So x = 10 in.

Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.
Answer:
Step-by-step explanation:
We use a for Adult and s for Student.
Assuming this, you have to start by writing two equations from the information provided:
900 total tickets were sold
a+s=900 ------(i)
they made $2,820 and adult tickets cost $4 and kids tickets cost $2.50
2820=4a+2.5s ------(ii)
lets solve for a in the first equation:
a=900-s
we can plug this into the second equation and solve for s
2820=4(900-s)+2.5s
2820=3600-4s+2.5s
2820=3600-1.5s
-780=-1.5s
s=520
we can plug this into the first equation and solve for a:
a+520=900
a=380
Total adult ticket sold : 380
Total student ticket sold = 520
Cost of adult tickets = 380 * 4 = $1520
Cost of student tickets = 520 * 2.5 = $1300

Two friends plant a tree and record the height of the tree each following year to track its growth. The data can be represented by the linear model y = 4.3z +3.25, where y represents the height of the tree, in feet, and z represents the number of years since it was planted.
Based on the linear model, what is the expected height of the tree in 8 years?
3.25
4.3
31.2
37.65
Answer:
D.) 37.65
Step-by-step explanation:
I know that 8 is an input based on this word problem. So, then I plug in the 8 for z and solve to find the expected height of the tree in 8 years.
y=4.3z+3.25
y=4.3(8)+3.25
y=34.4+3.25
y=37.65
In 8 years the expected height of the tree is 37.65

In triangle XYZ, m∠Z = (5m − 16)° and the exterior angle to ∠Z measures (3m + 12)°. Determine the value of m.
m = 3
m = 10.8
m = 18
m = 23
Answer:
Step-by-step explanation:
Each Exterior angle = 180° - Interior angle.
(3m + 12)° = 180° - (5m − 16)°
Then solve algebraically:
\(3m+12=180-5m-16\)
\(3m+12=-5m+164\)
\(8m+12=164\)
\(8m=152\)
m = 19
The value of m will be 23.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In triangle XYZ,
⇒ m ∠Z = (5m − 16)°
And, the exterior angle to ∠Z measures (3m + 12)°.
Now,
Since, The sum of angle and its exterior angle in a triangle will be 180°
Hence, We can formulate;
(5m − 16)° + (3m + 12)° = 180
Solve for m as;
5m - 16 + 3m + 12 = 180
8m - 4 = 180
8m = 180 + 4
8m = 184
m = 23
Thus, The value of m will be 23.

the area, a, of a trapezoid is given by the formula a=1/2h(c+d), where h is the height and c and d are the lengths of the bases rearrange the formula so that the height h of the trapezoid can be determined given the area and the lengths of the bases enter your answer in the box
Answer:
this is algebra remember algebra rules and thing really hard
Step-by-step explanation:
The formula for the height of the trapezoid will be h = 2A/(c+ d).
What is surface area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
In another meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.
Given a trapezoid with side lengths c and d and perpendicular distance as h
So, the area formula will be
A = (1/2)h(c + d)
Multiply both sides by 2
2A = h (c + d)
Divide by c + d into both sides
2A/(c + d) = h
Hence "The formula for the height of the trapezoid will be h = 2A/(c+ d)".

Order the numbers from closest to zero to farthest from zero:
4.38, l4.5l, l-4.6l, -l4.9l
HELPPPPP
The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.
With that being said, here is the order of the numbers from smallest to largest:
4.38
4.5
4.6
4.9
Answer:
Here are the numbers ordered from closest to zero to farthest from zero:
4.38 (closest to zero)
