I think x= -7 if I’m wrong my bad, good luck !
Answer:
after question;
-8*(-4)
-32
Step-by-step explanation:
it's too easy.please mark me brainliest
Instead of using the quotient rule, you can first expand <em>y</em> :
<em>y</em> = (4<em>x</em> - 1)^2 / <em>x</em> ^2 = (16<em>x</em> ^2 - 8<em>x</em> + 1) / <em>x</em> ^2 = 16 - 8/<em>x</em> + 1/<em>x</em> ^2
Then the derivative is
d<em>y</em>/d<em>x</em> = -8/<em>x</em> ^2 - 2/<em>x</em> ^3
The tangent to the curve at (-1, 25) then has a slope or gradient of
d<em>y</em>/d<em>x</em> = -8/(-1)^2 - 2/(-1)^3 = -6
Answer:
False
Step-by-step explanation:
Answer:
the $45 per hour mechanic worked 2 hours
the $120 per hour mechanic worked 8 hours
Step-by-step explanation:
45 X 2 = 90
120 X 8 = 960
960 + 90 = 1050
