Answer:
x equals -1 and it also equals -13. They are both considered the roots.
Step-by-step
- (x+6)^2= 49 to get rid of the exponent square root each side of the equation.
- (x+6)= √49 Find square root of 49.
- (x+6)= ±7 It could be positive 7 or -7 because both of them squared equal 49. Now solve for each possible equation, (x+6)= 7 and (x+6)=-7.
- (x+6)=7 subtract 6 from each side.
- x= 1
- (x+6)=-7 Subtract 6 from each side.
- x=-13
- So the answers are -13 and 1.
Answer:
I would use Pythagorean theorem To find the lengths and just plug in numbers from the answer choices.

Answer:
Add like terms 7x - 9
Step-by-step explanation:
We only know the value of <span>f(5)</span>
therefore we need to figure out what we would put in for x in <span>f(<span>1/3 </span>x)</span> to get 5
set
<span><span>1/3 </span>x=5</span><span>x=15
</span>now if <span>x= 15</span> then <span>f(<span>1/3 </span>x)
= f(<span>1/3</span>×15)
= f(5)=8
</span><span>and so
</span><span><span>1/4</span>×8−2=2−1=1
</span>therefore the "corresponding point" is <span><span>(15,1)</span></span>
