Answer: $18.90
Step-by-step explanation:
That's OK, but you have not said which variable you want to solve it for.
<u>To solve for 'x':</u>
<span>c + ax = dx
Subtract c from each side: ax = dx - c
Subtract dx from each side: ax - dx = -c
Factor the left side: x (a - d) = -c
Divide each side by (a - d) : x = -c / (a - d) or <u>x = c / (d - a)</u> .
</span><span><u>To solve for 'c': </u>
</span><span> c + ax = dx
Subtract ax from each side and factor: <u>c = x (d - a) </u>
</span><u>To solve for 'd': </u>
<span>c + ax = dx
Divide each side by 'x': d = c/x + a .
<u>To solve for 'a':</u>
</span><span><span> c + ax = dx</span>
Subtract 'c' from each side: ax = dx - c
Divide each side by 'x': <u>a = d - c/x </u>.

Answer:
shift the graph up 1 unit
Step-by-step explanation:
d is the vertical shift
+1 means we shift the graph up 1 unit

Answer:
{(12-4) + (15-8)}x = 65
Step-by-step explanation:
The amount Amber earns per week
12-4
The amount Nathan earns per week
15 -8
The total amount per week they earn together
(12-4) + (15-8)
Multiply by x weeks
{(12-4) + (15-8)}x
Set this equal to 65 to be the amount they need to equal 65 dollars
{(12-4) + (15-8)}x = 65
