Determine coefficients a and b such that p(x)=x2 ax b satisfies p(1)=5 and p′(1)=11.
Murrr4er [49]
p(x)=x^2+ax+b
p'(x)=2x+a

Given that p'(1)=11, you have

p'(1)=2+a=11\implies a=9

and given that p(1)=5, you have

p(1)=1+9+b=5\implies b=-5

So you get

p(x)=x^2+9x-5

Write an equation in slope-intercept form of the line that passes through (0, 2) and (8, 8).
erastova [34]

Answer:

y = 3/4x + 2

Step-by-step explanation:

First, find the slope using rise/run (y2 - y1) / (x2 - x1)

(8 - 2) / (8 - 0)

6/8

= 3/4

We were already given the y-intercept, which is (0, 2)

Now, we can plug in the slope and y-intercept into the slope intercept equation, y = mx + b, where m is the slope and b is the y-intercept:

y = 3/4x + 2 is the equation
