Equation of the line that passes through (-2, 8) with a slope of 0, can be written in point-slope form, $y - y_1 = m(x - x_1)$ and also in slope-intercept form, $y = mx + b$ .

Using a point, (-2, 8) and the slope (m), 0, substitute x1 = -2, y1 = 8 and m = 0 in $y - y_1 = m(x - x_1)$ .

Thus:

$y - 8 = 0(x - (-2))$

$y - 8 = 0$

Rewrite in slope-intercept form

$y - 8 + 8 = 0 + 8$ (addition property of equality)

$y = 8$

Susan ran 4 miles in 20 minutes. How many minutes will she take to walk 3 miles

inn [45]

Answer: 15

Step-by-step explanation:

4/20 is your ratio. Simplify it and it'd be 1/5. This means in 1 mile has been walked in 5 minutes. 3 x 5 is 15, so it took Susan 15 minutes.

Find the volume of this sphere. Use 3 for TT. V ≈ [?]in³ V = πr³ 5in Entering

nydimaria [60]

Answer:

500

Step-by-step explanation:

r = 5

r³ = 125

V = (4/3)pi(r³)

pi = 3

V = (4/3)3(125)

/3 and x3 cancel

V = 4 x 125

V = 500
