mike makes a commission of 10% on each tv set sold at store. Each tv costs $120. how much money will he make as commission if st
Leni [432]

The answer is he will make $300 commission for 25 TV sets sold.  The first thing you need to do is find out how much commission he makes on each TV. So we take $120 and divide by 10% and that gives us $12.  So $12 is the amount of commission per TV. Then we just need to multiply the $12 by 25 TV sets. That gives us the answer of $300 commission total.

A second way to solve this problem is by taking the $120 and multiplying that by the 25 TV sets.  That gives you $3,000 total for the 25 TV sets.  Then you just divide the 10% commission Mike will make.  That also gives you the answer of $300 commission.

The graph of linear function f passes through the point (1, -9) and has a slope of -3. What is the zero of f ?
den301095 [7]

Answer:

-2

Step-by-step explanation:

The standard equation of a line is y = mx+c

m is the slope

c is the intercept

Given

Slope = -3

Get the intercept c;

Substitute m = -3 and (1, -9) into y = mx+c

-9 = -3(1) + c

-9  = -3 + c

c = -9 + 3

c = -6

The equation becomes

y = -3x + (-6)

y = -3x-6

f(x) = -3x-6

The zero of f occurs at f(x) = 0

0 = -3x-6

3x = -6

x = -6/3

x = -2

Hence the zero of the function is -2
