Answer:
Step-by-step explanation:
If you let y=2x, you can plug it into the other equation.
x+2x=-9
Then solve that equation.
3x=-9
x=-3
Then use y=2x to find y.
y=2(-3)=-6
y=-6
The correct answer is C. y = 1/2x + 7
In order to find this, we first have to look for the slope. We can do that by using the slope formula below.
m(slope) = (y2 - y1)/(x2 - x1)
m = (8 - 6)/(2 - -2)
m = 2/4
m = 1/2
Now we can solve using the slope intercept form and a given point.
y = mx + b
8 = 1/2(2) + b
8 = 1 + b
7 = b
Now we can put these into the equation and model as y = 1/2x + 7
Answer:
7x² + x + 3
Step-by-step explanation:
Step 1: Write expression
(3x² - 2x + 1) + (4x² + 3x + 2)
Step 2: Combine like terms
7x² + x + 3
Answer: True
Step-by-step explanation: Its true because you are either adding number or subtracting, unlike geometric.
