mars1129 [50]

Answer:

10.5 hours

Step-by-step explanation:

To find the number of hours she babysat last week subtract 5 from 11 which is 7 hours. 7 hours is equal to 2/3 of the many hours. If she babysat h hours last week then solve for h using 2/3 h = 7.

Solve the equation by multiplying each side by the reciprocal.

3/2 * 2/3h = 7*3/2

h = 21/2

h = 10.5 hours

A line includes the points (8,-2) and (-8,-4). What is the slope intercept
VladimirAG [237]

Answer:

The equation of the line would be y = 1/8x - 3

Step-by-step explanation:

to find the slope intercept form of the line, you must first find the slope. You can do this using the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-2 - -4)/(8 - -8)

m = 2/16

m = 1/8

Then you can use this slope along with either point in point-slope form. Then solve for y.

y - y1 = m(x - x1)

y + 4 = 1/8(x + 8)

y + 4 = 1/8x + 1

y = 1/8x - 3

irina1246 [14]

Answer:

Option B.

Step-by-step explanation:

The given expression is

\dfrac{10x^2-32}{4}

We need to find the simplified form of given expression.

Taking out GCF from the numerator.

\dfrac{2(5x^2-16)}{4}

Cancel out common factors.

\dfrac{5x^2-16}{2}

The expression \dfrac{5x^2-16}{2} is the simplified form of given expression.

Therefore, the correct option is B.
