8 0

Answer:

x = 72

Step-by-step explanation:

$9 + \frac{3}{4} x = \frac{7}{8} x - 10 \\ \frac{3}{4}x - \frac{7}{8} x = - 10 - 9 \\ \frac{6}{8} x - \frac{7}{8} x = - 19 \\ - \frac{1}{8}x = - 19 \\ x = \frac{ - 9}{ - \frac{1}{8} } \\ x = 72$

A four line classified ad costs 25 for a week. Each additional line costs 2. What is the weekly cost for a 12 line ad

faust18 [17]

Answer: 41

Step-by-step explanation:

If each line costs 2, then for the four-line ad, the cost is the initial price plus 4(2), meaning the initial cost is 25-8=17.

Thus, the cost of a 12-line ad is 17+2(12)=41

You are riding a roller coaster when a shoe falls off your foot. The function y=300−16t2 represents the height y (in feet) of th

Juli2301 [7.4K]

Answer:

Time to land on 11ft is 4.25 seconds

Step-by-step explanation:

Given

$y = 300 - 16t^2$

Required

Solve for t when height is 11ft

This implies that $y = 11$

So: substitute 11 for y in $y = 300 - 16t^2$

$11 = 300 - 16t^2$

Collect Like Terms

$16t^2 = 300 - 11$

$16t^2 = 289$

Express both sides as squares

$4^2 * t^2 = 17^2$

$(4t)^2 = 17^2$

Take square roots of both sides (ignore negative)

$4t = 17$

Solve for t

$t = \frac{17}{4}$

$t = 4.25$

Hence, time to land on 11ft is 4.25 seconds
