The answer is <span>y = x2 − 4
if you try to factor out all of the equations given to you (ex. 0=x2+4x+2), the only equation that can be factored out is </span><span>y = x2 − 4.
</span><span>
y = x2 − 4
</span><span>0= x2 − 4
</span>0=(x-2)(x+2)
0=x-2   0=x+2
2=x      x=-2

What is the linear function for an initial value of 3 and increases by 1/4 when x increases by 1?
Y_Kistochka [10]
Y = (1/4)x + 3 is the linear function.
When x = 0, the initial value is 3.
When x increases by 1, 1/4 is added to the previous value.

Solve: 2x - 3y = 9 and x + 2y = 1​
mash [69]

Answer:

(3, - 1 )

Step-by-step explanation:

Given the 2 equations

2x - 3y = 9 → (1)

x + 2y = 1 → (2)

Rearrange (2) expressing x in terms of y by subtracting 2y from both sides

x = 1 - 2y → (3)

Substitute x = 1 - 2y into (1)

2(1 - 2y) - 3y = 9

2 - 4y - 3y = 9

- 7y + 2 = 9 ( subtract 2 from both sides )

- 7y = 7 ( divide both sides by - 7 )

y = - 1

Substitute y = - 1 into (3) for corresponding value of x

x = 1 - 2(- 1) = 1 + 2 = 3

solution is (3, - 1 )
