Y = 2x + 5 for x = 1.

Alisiya [41]

Since you know the value of x, you can substitute/plug it into the equation to find the value of y:

y = 2x + 5 Plug in 1 into "x" since x = 1

y = 2(1) + 5

y = 7

When x = 1, y = 7 --> (x, y) = (1, 7) Your answer is #4

Write the quadratic function f(x) = x2 – 2x – 8 in factored form.

IRINA_888 [86]

Answer:

f(x) = (x-4)(x+2)

Step-by-step explanation:

f(x) = x^2 – 2x – 8

What 2 numbers multiply to -8 and add to -2

-4*2 = -8

-4+2 = -2

f(x) = (x-4)(x+2)

Does the point (0,4) make either equations y=-2x and y=x+3 true? Explain.

Nikolay [14]

Answer:

Neither

Step-by-step explanation:

To verify, we substitute the values in the equations:

$y = -2x\\y = -2 \times 0\\y = 0$

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.

$y = x+3\\y= 0+3\\y = 3$

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.
