Answer:
56 because you have to multiply 28 times 2
Answer:
(-1, 4)
Step-by-step explanation:
We are told that:
y = -2x + 2 and
y = 7x + 11.
We can eliminate "y" by setting these two equations = to each other:
-2x + 2 = 7x + 11.
We need to solve this equation for x.
Adding 2x to both sides, we get 2 = 9x + 11.
Subtracting 11 from both sides results in -9 = 9x. Thus, x = -1.
Find y by subbing -1 for x in either of the given equations.
If we use the 2nd equation, then y = 7(-1) + 11, or y = 11-7, or y = 4.
The solution of this system of linear equations is (-1, 4)
34 and 33 because....
The 3 is multipling itself by two and the product would be 6. Then the six subtracts itself from 1 making the answer 5.

Answer:
-8
Step-by-step explanation:
All you have to do to solve this equation is plug "-3" into the equation where you see "x"
![f(x)=-x^2+1\\f(-3)=-(-3)^2+1\\f(-3)=-(9)+1\\f(-3)=-9+1\\f(-3)=-8](https://tex.z-dn.net/?f=f%28x%29%3D-x%5E2%2B1%5C%5Cf%28-3%29%3D-%28-3%29%5E2%2B1%5C%5Cf%28-3%29%3D-%289%29%2B1%5C%5Cf%28-3%29%3D-9%2B1%5C%5Cf%28-3%29%3D-8)
