D. 3
F(x) is referring to y. The question is asking what x is when y is 4.
Answer:
C
Step-by-step explanation:
subtracting 289 from both sides, will make one side will be equal to zero.
thus we can then easily solve for b.
can this answer get the brainliest tag?
1/10 = .1, and 3/33 = .0909090... it is equivalent if you estimate.
Substitution
-2x+8=x^2-9x+18
x^2-7x+10=0
Factoring, we get
(x-5)(x-2)=0
x=5, x=2
If x equals 5,
y=-2(5)+8=
-10+8=
-2
Therefore, we derive our first solution:
<h2><u><em>
x=5,</em></u></h2><h2><u><em>
y=-2</em></u></h2>
Now we solve for our second x
If x=2,
y=-4+8=
4
Therefore, we derive our second solution:
<h2><u><em>
x=2</em></u></h2><h2><u><em>
y=4</em></u></h2>
<u><em></em></u>
