Answer:
x = 9
Step-by-step explanation:
6 × 9 = 54
54 + 15 = 69, which is less than 70.
Answer:
- g(-x) = 70 +3x
- -g(x) = -70 +3x
- -g(-x) = -70 -3x
Step-by-step explanation:
Put the minus signs where the problem statement tells you. As with any function, the argument replaces the variable in the function definition. That is, for g(-x), you put (-x) where x is in the definition of the function.
g(-x) = 70 -3(-x) = 70 +3x
-g(x) = -(70 -3x) = -70 +3x
-g(-x) = -(70 -3(-x)) = -70 -3x
1,3,4 just match the markings.
Answer:
Step-by-step explanation:
Let one number = x
The other number = (-8) - x
Their product = 7
x*( -8 - x) = 7
x*(-8) - x*x = 7
-8x - x² = 7
0 = 7 + 8x + x²
x² + 8x + 7 = 0
x² + 7x +x +7 = 0
x(x + 7) + (x+7) = 0
(x + 7)(x + 1) = 0
x + 7 = 0 ;x + 1 = 0
x = -7 ; x = -1
The two integers are: (-7) and (-1)
