Help me solving number 22 & 24. Thanks:)

Answer:

Question 22

x intercept is 7

y intercept is 4

The answer is C

Question 24

x intercept is -4

y intercept is 7

The answer is B

Step-by-step explanation:

x and y intercepts are the points at which the graph meets x and y axes.

x and y intercepts can be found the following way,

y intercept - substitute 0 to x

x intercept - substitute 0 to y

Question 22

$7y=28-4x$

Substitute x=0 to find the y intercept

$7y=28-4*0$

= $7y=28$

= $y=4$

Substitute y=0 to find x intercept

$7*0=28-4x$

= $0=28-4x$

= $4x=28$

= $x=7$

Therefore,

x intercept is 7

y intercept is 4

The answer is C

Question 24

$4y=7x+28$

Substitute x=0 to find the y intercept

$4y=7*0+28$

= $4y=28$

= $y=7$

Substitute y=0 to find x intercept

$4*0=7x+28$

= $0=7x+28$

= $-7x=28$

= $x=-4$

Therefore,

x intercept is -4

y intercept is 7

The answer is B

Answer:

1: B

2: H

3. C or D (it's hard to tell, especially without an equation)

4. J

5. A

6. G

7. B

Step-by-step explanation:

1:

f(x) - g(x)

(x^2 + 8x) - (3x - 5) Distribute the negative

x^2 + 8x - 3x + 5 Combine like terms

x^2 + 5x + 5

2:

f(g(x))

Plug g(x) into f(x)

(2x - 1)^2 - 3

Immediately we can see that there will be a 4x^2 (because 2x times 2x = 4x^2) so we know the answer will be H because that's the only option with 4x^2

3:

The line starts at -4 on the x axis and goes infinitely to the right so everything greater than (and maybe equal to) -4.

On the y axis, the line starts at 0 and goes infinitely up so everything greater than (and maybe equal to) 0.

4:

To find the inverse of a function:

f(x) -> y

Switch x and y

Solve for y again

x = 3 +5y

x-3 = 5y

(x-3)/5 = y

5:

If option A were inverse functions, h(x) would be

x = 2y + 9

x - 9 = 2y

(x-9)/2 = y

Which could also be written as (1/2)x - 9/2 or (1/2)x - 4.5 but not (1/2)x - 9

6:

As y approaches -1, x approaches 1. Going the other direction,

As y approaches positive infinity, x approaches positive infinity.

7:

The number inside directly affecting the x moves the function left and right (left is positive, right is negative). The number outside moves the function up and down. So (x + 4) moves it left 4 and the +1 moves it up 1.
