2x - 2y = -12
- 2y = -2x - 12
y = x + 6
4x - 7 (x + 6) = -15
4x - 7x - 42 = -15
-3x - 42 = -15
-3x = 27
x = -9
y = -9 + 6
y = -3
(-9 , -3) is the solution
Answer:
J
Step-by-step explanation:
Answer: 1/25
Step-by-step explanation:
(1/5) * (1/5) = 1/25
Since they are consecutive, we can define the two unknowns with ease.
The left page (has a smaller value) can be defined as X, and the right page can be defined as X+1.
So,
X + (X+1) = 293
2x+1 = 293
2x = 292
x = 146
So, as we defined before, the smaller page number is equal to x. Therefore, the smaller page number is 146, and the larger page number is 147.
Answer:
Step-by-step explanation:
(x² + 6x + 9)(x)= x²*x + 6x*x + 9*x = x³ + 6x² + 9x
