Answer:
Linear
Step-by-step explanation:
Linear means the graph is a straight line. If you plot the points, the line will be straight, therefore it is linear.
A. Multiplication is the ONLY function that reverses what division did. If you did 56/-14 = n, then n x -14 should equal 56.
4 because you can draw a line horizontally and a line vertically and also two lines diagonally.
Answer:
Step-by-step explanation:
Remember:
![(\sqrt[n]{a})^n=a\\\\(a+b)=a^2+2ab+b^2](https://tex.z-dn.net/?f=%28%5Csqrt%5Bn%5D%7Ba%7D%29%5En%3Da%5C%5C%5C%5C%28a%2Bb%29%3Da%5E2%2B2ab%2Bb%5E2)
Given the equation 
, you need to solve for the variable "x" to find its value.
You need to square both sides of the equation:
Simplifying, you get:
Factor the quadratic equation. Find two numbers whose sum be 7 and whose product be -8. These are: -1 and 8:
Then:
Let's check if the first solution is correct:
(It checks)
Let's check if the second solution is correct:
(It does not checks)
Therefore, the solution is:
Answer:
9 tshirts
Step-by-step explanation:
Money he had for t shirts= $75
Cost of shipping= $3
Money left for t shirts= $75-$3=$72
Cost of 1 t shirt= $8
We can find the answer with two ways:
1st way: tshirts of $8=1
tshirts of $72=72/8
=$9
2nd way: Cost ($) 8 72
T shirts 1 x
8/1=72/x
by cross multiply
x=72/8
x=9
