The distance covered by Greta after biking at a speed of 12 miles per hour for x hours is 12x miles.

<h3>What is speed?</h3>

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

Greta starts at mile marker S on a bike trail and is biking at a speed of 12 miles per hour. If she biked for x hours:

Distance covered = 12 mph * x = 12x miles

The distance covered by Greta after biking at a speed of 12 miles per hour for x hours is 12x miles.

What are the solutions for x when y is equal to 0 in the quadratic function y=x^2-8x

Elena L [17]

I would use the quadratic formula for this:

x = -b ± √b² - 4ac over 2a
x = 8 ± √64 - 4(1)(0) over 2(1)
x = 8 ± √64 over 2
x = 8 ± 8 over 2 [simplify]
x = 4 ± 4
x1 = 4 + 4 x2 = 4 - 4
x1 = 8 x2 = 0

Thus, the solutions for x would be 0 and 8.

An electronics store makes a profit of $72 for every standard CD player sold and $90 for every portable CD sold. the managers ta

Alisiya [41]

s -> no: of standard CD players sold

p -> no: of portable CD players sold.

Profit Per Standard CD player=72$

Profit per Portable CD player =90$

Target Amount =360$

In short: The combined sales of Both the CD player's must exceed or atleast become equal to 360$ to acquire the target.

Thus; the inequality can be stated as:

 72(s) + 90(p) ≥360

-> 36(s) + 45(p) ≥180

-> 12(s) +15(p) ≥ 90

 _______________

->| 4(s) + 5(p) ≥ 30 |
