Answer:
y=(-5/3)x+29
Step-by-step explanation:
we will use the base formula y=mx+b
In order to be perpendicular, the slope must be the flipped fraction and have the opposite sign, so our m is (-5/3)
y=(-5/3)x+b
You can plug in the (9,14) point in order to find the b
14=(-5/3)(9)+b
14=(-45/3)+b
14=(-15)+b
14+15=b
29=b
and so altogether our equation is y=(-5/3)x+29
Answer and Step-by-step explanation:
This is the answer.
a / 75 = 15 / 100
100a = 75 * 15 [cross multiplication]
a = 11.25
i hope this helps!!! :D
Answer:
Solution is x=-3 and x =1, because that is zero od function y=-x^2-2x+3
