Answer:

6) C 1

7) A 3 (im not sure for this one because it's blurry)

8) C 1

Step-by-step explanation:

6) Replace the f(x) for -1 since we are told f(x) = -1. We then need to use the inverse operation to get x by itself.

- 1 =  \frac{x - 3}{ 2}

Since the opposite of division (which is indicated by the fraction line) is multiplication, we need to multiply the number on the left (-1) times 2.

- 2 = x - 3

For this step, the opposite of subtraction is addition so in this step, we must add 3 to -2.

1 = x

7) Can't explain cause I'm not sure if I'm right

8) To find out the slope of two coordinates we must use the following to determine it.

<h3>(IN THE PICTURE ATTACHED)</h3>

In this case, the y with the little two will be 4 and the y with the little one is 1. 4-1 is 3 and that's the y cooridnate sorted

For the x coordinate, the x with the little two is 1 and the x with the little one is -2. Thus, we must solve 1-(-2) which also equals 3.

<h3>Since the final coordinates are 3/3 and it simplifies, the final answer is 1.</h3>

I need this math problem done as soon as possible!
Vesna [10]

Answer:

See below

Step-by-step explanation:

<u>Parent function:</u>

  • y = 3ˣ

<u>Transformed function:</u>

  • y = 4(3)⁻²ˣ⁺⁸ + 6, (note. I see this as 8, sorry if different but it doesn't make any change to transformation method)

<u>Transformations to be applied:</u>

  • f(x) → f(-x) reflection over y-axis
  • f(-x) → f(-2x) stretch horizontally by a factor of 2
  • f(-2x) → f(-2x + 8) translate 8 units right
  • f(-2x + 8) → 4f(-2x + 8)  stretch vertically by a factor of 4
  • 4f(-2x + 8) → 4f(-2x + 8) + 6 translate 6 units up

HELP!!!!! ME!!! NEED HELP!
Katena32 [7]
Y = -4x + 2
3x + 2y = 6 (or in y-intercept form y=-3/2x + 3)

2x - y = 7 equals y = 2x -7 in y-intercept form. This means that the line has a positive slope and therefore goes upwards. This cannot be a potential equation because the line shown is clearly pointing downwards.

y=5 indicates that the line is a horizontal line that neither points upwards or downwards. This cannot be a potential equation because the line is pointing downwards. 

The only possible equations left are y= -4x + 2 and 3x + 2y = 6, both of which graph a line pointing downwards because their slopes are negative. Hope this helps!
