<span>Using the information we have
3x+4=40
Do the same to each side of the equation to eliminate for x.
3x+4=40 Minus 4 from each side
3x=40-4
3x=36
Divide 3 from each side
x=36/3
x=12
AC=3x+4
insert the value of x
3(12)+4=40
AC=40
AD=20</span>
Answer:
Step-by-step explanation:
Since y = -3 we can plug straight into the other equation
--> -x + 2y = -6
-x + 2(-3) = -6
-x - 6 = -6
-x = 0
x = 0
To graph this draw a horizontal like across the page at y = -3 and a vertical line down the page to represent x = 0
The point where these lines intersect is (0,-3)
So that would be the ordered pair solution.
The answer is 3.42 x 10^6 because we moved the decimal 6 places to the left. Hope this helps:)
