Given:
- a=2
- b=-3
Question:
2a - 4b
Step by step explanation:
Step 1:
2×2-4×(-3)
Step 2:
4-4(-3)
Step 3:
4+12
Step 4:
16
So 16 is correct answer
hope it helped you :)
100,000 + 75,000 = 175,000. To get the answer, you add the two.
Answer:
3rd answer f(x) = 3(x-8)(x+2)
Step-by-step explanation:
The x-intercepts are the points at which the parabola intersects the x-axis.
Function y = a(x - r₁)(x - r₂) is in factored form, where r₁ and r₂ are x-intercepts so if r₁ = 8 and r₂ = -2 then
y = a (x-8)(x-(-2))=a(x-8)(x+2)
For y intercept plug in (0,-48) in equation and calculate a:
-48 = a (0-8)(0+2)
-48 = a(-8)(+2)
-48 = -16a divide by -16
a = 3
Function is y = 3(x-8)(x+2)
Answer:
B. 1 and -2
Explanation:
First, add up the equations:
x-x+3y+y=4
4y=4
y=1
Now, plug y into any of the original equations above and solve for x:
-x+1=3
-x=2
x=-2
Therefore, the answer is B. 1 and -2
