Answer:
- 2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 2, - 1 ] , then
f(b) = (f(- 1) = 5 ← corresponding value of y (- 1, 5 )
f(a) = f(- 2) = 7 ← corresponding value of y (- 2, 7 ) , thus
average rate of change = = = - 2
x=10
<em>X=2</em>
3x-15=7-8x
3x+8x=7+15
11x=22
x=
x=2
$39.2
The sale price will be 20% of $49 subtracted from $49
That’s
20% /100% x $49
0.2 x $49
$9.8
Sale price = $49 - $9.8
= $39.2
The sale price is $39.2
