Step-by-step explanation:
Given,
![9 {x}^{2} + 13x - 15](https://tex.z-dn.net/?f=9%20%7Bx%7D%5E%7B2%7D%20%20%2B%2013x%20-%2015)
and
![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
Substitute x = 2 into expression.
![9 {x}^{2} + 13x - 15 = 9( {2}^{2} ) + 13(2) - 15 \\ = 9(4) + 26 - 15 \\ = 36 + 26 - 15 \\ = 62 - 15 \\ = 47](https://tex.z-dn.net/?f=9%20%7Bx%7D%5E%7B2%7D%20%20%2B%2013x%20-%2015%20%3D%209%28%20%7B2%7D%5E%7B2%7D%20%29%20%2B%2013%282%29%20-%2015%20%5C%5C%20%20%3D%209%284%29%20%2B%2026%20-%2015%20%5C%5C%20%20%3D%2036%20%2B%2026%20-%2015%20%5C%5C%20%20%3D%2062%20-%2015%20%5C%5C%20%20%3D%2047)

Step-by-step explanation:
A graphing calculator does this nicely.
Answer:
assume an approximate value for the variable that will simplify the equation.
solve for the variable.
use the answer as the second approximate value and solve the equation again.
repeat this process until a constant value for the variable is obtained.
Answer:
24%
Step-by-step explanation:
I think this is right. im sorry if its not but i went to a percent calculator and checked my answer. hope this helped :)
I’m fairly sure it is the last one. But the pictures are hard to see. 3/2 is the slope and -1 is the y intercept. Find the point at (0,-1) , the y intercept. Then go up 3 and over 2 to find the next point
