Answer:

Z = -5

Step-by-step explanation:

1) multiply bracket

-4 x 2z = - 8z

-4 x 6 = - 24

2) put back into equation

-8z - 24 - 12 =4

3) collect like terms

-8z - 36 =4

4) get z alone

-8z - 36=4

+36 +36

-8z = 40

5) find z

-8z =40

divide both sides by - 8

Z= - 5

Answer:

<h2><em><u>z</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-</u></em><em><u>5</u></em></h2>

Step-by-step explanation:

-4(2z+6)-12 = 4

=> -8z - 24 - 12 = 4

=> -8z = 4 + 12 + 24

=> -8z = 40

=  > z =  \frac{40}{ - 8}

=> <em><u>z</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>5</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

Step-by-step explanation:

In the function f(m)= -50m+300

-50 is the gradient meaning it is the rate of change per month. This means that the rate of change is -50 since this is the coefficient of m.

Also, -50m must be negative since m represents a month and you cant have negative months, so you know that the amount of money is decreasing
