Answer:

#43: D

#44: 11

Step-by-step explanation:

#43-

1. 2x + 4 =K= 2x+22

place function together

2. combine like terms

2x+4=k=2x+22

-2x -2x

4=K= 22

-4 -4

3. gives you the answer

which is K = 18

#44 f(x) = 2/3x + 3 .....f(12)

1. place 12 un the equation

f(12) = 2/3 × 12 +3

2. f(12) = 8+3

3. f(12)= 11

This is the best I can do

The value of y is directly proportional to the value of x. If y = 35 when x = 140, what is the value of y when x = 70?

antiseptic1488 [7]

Answer:

y = 17.5

Step-by-step explanation:

Use the direct proportion equation, y = kx

Plug in the x and y values to solve for k

y = kx

35 = k(140)

0.25 = k

Then, plug in the k value and given x value into the equation, and solve for y

y = kx

y = 0.25(70)

y = 17.5

Please help me with this question

Hunter-Best [27]

Answer:

y = $\frac{1}{2}$ x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 2 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-2}$ = $\frac{1}{2}$

The line crosses the y- axis at (0, 1) ⇒ c = 1

y = $\frac{1}{2}$ x + 1 ← equation of line
