Answer:
(r-7)(r+2)
Step-by-step explanation:
First, let's look at the -14. Possible factors for that number are (-2, 7) (2, -7) (1, -14) and (-1, 14).
Now, let's look at the -5. How can we make -5 with the pairs that we just found?
The only possible way is 2 and -7 (added together equals -5)
Answer:
3 +2 = 5 and 12 + 5 = 17

Answer:
$0.75
Step-by-step explanation:
Greg spends $0.45 on a eraser and $0.30 on a pen. How much money does Greg spend?
Well first you find the key words, (How much) which means you will be using addition in this problem. The numbers you will be adding are $0.75 and $0.30 which equals, $0.75
2y + x = -6
y = -2x + 0
We can substitute the second equation into the first one.
2y + x = -6
2(-2x + 0) + x = -6
-4x + x = -6
-3x = -6
Divide -3 on both sides.
x = 2
Now, plug x = 2 into any equation and solve for y.
y = -2x + 0
y = -2(2) + 0
y = -4
The solution to the system of equations is (2,-4).
