Use elimination to solve the system 4x + 7y = -14 and 8x + 5y = 8 for x. Please show work! Will give brainliest!!!
7nadin3 [17]

Answer:

x=3 and 1/2

Step-by-step explanation:

4x+7y=-14

8x+5y=8

2(4x+7y=-14)

8x+14y=-28

8x+5y=8

9y=-36

y=-4

8x+5(-4)=8

8x-20=8

8x=28

x=3 and 1/2

Find the equation, (f(x) = a(x - h)2 + k), for a parabola containing point (2, -1) and having (4, -3) as a vertex. What is the s
postnew [5]

Given that the vertex of the parabola is (4,-3)

The parabola passes through the point (2,-1)

We need to determine the standard form of the equation of the parabola.

<u>Standard form of the equation of the parabola:</u>

The standard form of the equation is y=a(x-h)^2+k where the vertex is (h,k) and a is the constant.

Substituting the vertex (4,-3) in the above equation, we get;

y=a(x-4)^2-3  ---------------(1)

Substituting the point (2,-1) in the above equation, we have;

-1=a(2-4)^2-3

-1=a(-2)^2-3

-1=4a-3

  2=4a

  \frac{1}{2}=a

Thus, the value of a is \frac{1}{2}

Substituting the value of a in the equation (1), we get;

y=\frac{1}{2}(x-4)^2-3

Thus, the standard form of the equation of the parabola is y=\frac{1}{2}(x-4)^2-3
