Ok. First you isolate the variable. So Ill take 12 which is posotive, and subtract 12 from the 15 and the 12. Now all were left with is -x=3. We multiply each side by -1 to give us x=-3. Hope this helps!

An employee earns $175 for 15 hours work.<br> Find the constant of variation.
LiRa [457]

Answer:

11.67

Izzy's heartbeat rate was measured on an EKG machine. After conversion, the function produced could be modeled by a sine functio
Amanda [17]
First, we calculate the amplitude
A = (1/2) (xmax - xmin)
A = (1/2) (8 - (-2)) = 5

Since we're given with the period which is pi, then the coefficient of x is just 1. So, the model is
y = 5 sin x

HELP MEEEEEEEEEEEEEEEEEEEEE!<br><br> what is the answer please also explain<br> –10p − 4 = 66
xxMikexx [17]

Answer:

P = -7

Step-by-step explanation:

-10p - 4 = 66 you take and isolate the -10p by adding 4 to both sides since 4 is negative in the problem then you get -10p = 70 and to get rid of the -10 you divide 70 by -10 to get P = -7.
