7 0

Answer:

$x=\frac{55}{7}$

Step-by-step explanation:

we have

$\frac{4}{7}=\frac{x-1}{12}$

solve for x

Multiply in cross

$(4)(12)=(7)(x-1)$

Divide by 7 both sides

$\frac{48}{7}=x-1$

Adds 1 both sides

$\frac{48}{7}+1=x$

$\frac{55}{7}=x$

Rewrite

$x=\frac{55}{7}$

SIZIF [17.4K]

Answer:

i think the answer is D

Step-by-step explanation:

87 degrees minus 10 degrees would give you 77 (which is the lowest temperature). then 77 degrees plus 17 degrees is 94 degrees. the difference between the highest temp and lowest (94-77) would be 17.

Given the function h(x)=-x^2+4x+12, determine the average rate of change of the function over the interval −2≤x≤4.

iris [78.8K]

Answer:

Step-by-step explanation:

The average rate of change of h(x) in the closed interval [ a, b ] is

$\frac{f(b) - f(a)}{b-a}$

Here [ a, b ] = [ - 2, 4 ] , then

f(b) = f(4) = - (4)² + 4(4) + 12 = - 16 + 16 + 12 = 12

f(a) = f(- 2) = - (- 2)² + 4(- 2) + 12 = - 4 - 8 + 12 = 0

Then

average rate of change = $\frac{12-0}{4-(-2)}$ = $\frac{12}{6}$ = 2
