Answer:

-2

Step-by-step explanation:

If f(x) = 2x² + 4x - 2

f(-2) = 2(-2)² + 4(-2) - 2

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

f(-2) = 8 - 8 - 2

f(-2) = -2

Answer:

<u>It</u><u> </u><u>is</u><u> </u><u>-</u><u>1</u><u>8</u>

Step-by-step explanation:

f(x) =  - 2 {x}^{2}  + 4x - 2

when x is -2, f(x) is f(-2):

f( - 2) =  - 2 {( - 2)}^{2}  + 4( - 2) - 2 \\ \\  f( - 2) =  - 8 - 8 - 2 \\  \\ f( - 2) =  - 18

I just need help with these few questions... please give me actual answers.
mario62 [17]

Answer:

Step-by-step explanation:

1. -7 = w + 5

w = -12

(-12 + 5 = -7)

2. -4p + 38 = 10

           -38     -38

-4p = -28

/-4        /-4

p = 7

3. -3 1/2 = -1 1/4b

   /1.25      /1.25

-2 4/5 = -b

2 4/5 = b

or

2.8 = b

A line with slope 3 passes through the point (0,10). What is the y-coordinate of the point on the line with x-coordinate 2?
lana [24]
Hello!

So to find the y-coordinate we need an equation for the line. The equation we can use is

y = mx + b

In this we already know m(the slope which is 3) and we can find b by plugging in the points that are given.

10 = 3(0) + b
10 = 0 + b
10 = b

So now that we've found b, we can use this in our equation

y = 4x + b

So now we can plug in the x-coordinate that we know (2) and find the y - coordinate.

y = 4(2) + 10
y = 8 + 10
y = 18

18 is your y-coordinate
