Hello!
To find our answer ,we will plug in each number of our domain and see what the outputs are. This will be our rangle.
-4(3.2)= -12.8
-2(3.2)= -6.4
0(3.2)=0
2(3.2)= -6.4
4(4.2)= 12.8
Now we order our numbers from least to to greatest.
-12.8,-6.4,0,6.4,12.8
Therefore, our answer is A.
I hope this helps!
Answer:
9x² + 28x - 32
Step-by-step explanation:
Given
(9x - 8)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
9x(x + 4) - 8(x + 4) ← distribute both parenthesis
= 9x² + 36x - 8x - 32 ← collect like terms
= 9x² + 28x - 32
Answer:
B
Step-by-step explanation:
The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
