Answer:
(-5,17) is a solution to the equation
Step-by-step explanation:
The equation is y = -2x+7
Substitute the values of x=-5 and y =17 into the equation and see if it is true
17 = -2(-5) +7
17 = 10+7
17=17
This is true so (-5,17) is a solution to the equation
Y=-3/2x + 2 this is because of algebra
Answer:
-20x^2 + 53x -18
Explanation:
FOIL
First terms
Outer terms
Inner terms
Last terms
So lets do our F:
5x * -4x = -20x^2
Now lets do our O:
5x * 9 = 45x
Now lets do our I:
-2 * -4x = 8x
Now lets do our L:
-2 * 9 = -18
Lets put all those together:
-20x^2 + 45x + 8x - 18
Combine like terms:
-20x^2 + 53x -18
