Answer:
y = 15x + 65
Step-by-step explanation:
To find the equation, we can use two points in the graph to find the parameters 'a' and 'b' in the equation:
y = ax + b
For the value x = 1, we have y = 80
For the value x = 9, we have y = 200
So we have that:
80 = a*1 + b
200 = a*9 + b
Making the second equation minus the first one, we have:
8a = 120
a = 15
Now we can find 'b':
80 = 15 + b
b = 65
So the equation is y = 15x + 65
Step-by-step explanation:

Answer:
10
Step-by-step explanation:
The square of the number must be 100, because the square root of one hundred is ten.
If you square 2^2 = 4, you see the square is two times as big as the number itself. 3^2 is 9, so the square is 3 times as big as the number. So the pattern is that the number being squared is the same number that governs how many times as big the square is. So ten would have a square 10 times as big, which 100, and the cube would be 1,000, which 1,000/10 = 10

Step-by-step explanation:
area is length times width for 2d shapes. do 4x10 the are is 40
Answer: 42
Step-by-step explanation
Switch x out with 3
using Pemdas do the exponent first
3^2 is 9
then multiply
5*9= 45
then subtract
45-3=42
