First you expand the multiplication so it will be more easier to sub in later.
6k-10

sub in k=5 into the equation
6(5)-10=20

Think I know this one but could do with some help

Andrei [34K]

Quick note: Since Riona wants to sell like 90 or 100 the answer I got was for 95.

I hope this helps you but the answer would be approximately about 83125.

The point-slope form:

$y-y_1=m(x-x_1)$

$m$ - slope

$(x_1,\ y_1)$ - point

We have the point $(3,\ -2)\to x_1=3,\ y_1=-2$ and the slope $m=\dfrac{2}{3}$

Substitute:

$y-(-2)=\dfrac{2}{3}(x-3)\\\\\boxed{y+2=\dfrac{2}{3}(x-3)}$

Evaluate 4<br> M-n if m= -7 and n = 2.

gregori [183]

Answer:

-30

Step-by-step explanation:

I'm assuming the equation is $4m-n$ . If it is not please tell me.

If we know the values of m and n, we can just substitute inside the expression.

$4(-7) - 2\\\\-28 - 2\\\\-30$

Hope this helped!
