Answer:

b. -2/3

Step-by-step explanation:

in addition a negative plus a negative does not equal a positive so we can already assume the answer is b but to be safe we can work this problem out in this way: 1/9 + 5/9 = 6/9 we simplify 6/9 and we get 2/3 so we slap the negative back on and boom -2/3

Let f (x) = -1/2(x + 2)+ 5

Answer:

Rate of change = -1

Step-by-step explanation:

Given:

f(x) = -½(x + 2)² + 5

Required:

Average rate of change from x = -3 to x = 1

Solution:

Rate of change = $\frac{f(b) - f(a)}{b - a}$

Where,

a = -3,

f(a) = f(-3) = -½(-3 + 2)² + 5 = -½(-1)² + 5 = 4.5

b = 1,

f(b) = f(1) = -½(1 + 2)² + 5 = -½(9) + 5 = 0.5

Plug in the values into the formula:

Rate of change = $\frac{0.5 - 4.5}{1 - (-3)}$

Rate of change = $\frac{-4}{4}$

Rate of change = -1

Write an equation in point slope form for the perpendicular bisector of the segment with endpoints M(-1,-3)and N (7,1)

Nataly [62]

Slope of segment here = 4/8 = 1/2
slope of perp needs to equal -2
midpoint of segment = (3,-1) so include that as a point:
y = -2(x-3)+1
(y- (-1)) = -2(x-3)
