Answer:
(-4,2)
Step-by-step explanation:
First we have to find a common multiple to use to add and find the system of equations. We need to eliminate one of the variables in order to solve.
Since 5 * 3 = 15, and 3 * -5 = 15, -15x and 15x will cancel each other out. Therefore x will be eliminated.
Before:
5x + 2y = -16
3x + 7y = 2
After:
15x + 6y = -48 <----------Now we solve for y
-15x + -35y = -10
+----------------------
-29y = -58
-29 -29
y = 2
Now what we do is we choose and equation and solve for x, since it is still unknown. Any equation is fine but I will choose the second one since it has easy numbers.
3x + 7y = 2
3x + 7(2) = 2
3x + 14 = 2
-14 -14
----------------------
3x = -12
3 3
x = -4
Therefore our final answer is (-4,2)
Answer:
LCD(8/
15
, 11/
30
, 3/
5
) = LCM(15, 30, 5) = 2×3×5 = 30
Step-by-step explanation:
To find the area, we have to use the F.O.I.L. method to solve (3x-2)*(4x-7)
-> 12x^2-21x-8x+14
= 12x^2 - 29x + 14
So the area of the rectangle would be 12x^2 - 29x + 14.

Answer: f(x)= 3/2x-2
Step-by-step explanation:
So if you know how to graph on a calculator and put all the points in, it'll give you all the points plotted and when i did that i got
f(x)= 3/2x-2
