Multiply the second fraction by two; which gets you 5/10 + 2/10 = 7/10
Answer:
y(-4) = 5
y'(-4) = -7
Step-by-step explanation:
Hi!
Since the tangent line T and the curve y must coincide at x=-4
y(-4) = T(-4) = 5
On the other hand, the derivative of the curve evaluated at -4 y'(x=-4) must be the slope of the tangent line. Which inspecting the tangent line T(x) is -7
That is:
y'(-4) = -7
Ok now that i understand the question better i say it is D
4/5 divided by 1/10 = 4/5 x 10/1 = 40/5 = 8
