Answer: A. No, because one x-value corresponds to two different y-values.

Step-by-step explanation:

A function is a kind of special relationship where each input has only a single output.

We take input variable as 'x' and output variable as 'y'.

In the given table, it can be seen that one input value corresponds to two two different output values.

i.e. 8 is the input value corresponding to 5 and 8 both.

It contradicts the definition of the function.

Hence, the given table doesn't represent any function.

A line contains the points (8,9) and (-12, -7). Using point-slope form, write the equation of the line that is parallel to the g

pogonyaev

Answer:

D. y+15 = 4/5(x+5)

Step-by-step explanation:

A line contains the points (8,9) and (-12, -7).

(y2 - y1) = m(x2 - x1)

(9 - (-7))= m (8 -(-12))

16 = m*20

m = 16/20 = 4/5

Given line has slope m= 4/5.

Parallel line has the same slope m = 4/5.

Point-slope equation is (y - y1) = m(x - x1).

We have slope m = 4/5, and point (-5, -15).

So,

(y - (-15)) = 4/5(x - (-5))

y+15 = 4/5(x+5)

We have two conditions that we need to apply:

Condition one: Salary at least 33500
Condition two: No college education is required

Looking at the table below, there are only two jobs that don't require college certificate; Private Detective and Sheet Metal Worker.

Between these two jobs, the one that gives salary at least 33500 is Sheet Metal Worker

Hence, based on the data given, Jasmine can plan to take on training as Sheet Metal Worker

If  BD BC, BD = 5x – 26, BC = 2x + 1, and AC = 43, find AB.

Bumek [7]

Answer:

AB = 24

Step-by-step explanation:

BD = 5x – 26

BC = 2x + 1

AC = 43

Using the segment addition postulate, AC = AB + BC.

We know that BD = BC, BD = 5x-26 and BC = 2x+1. We can set up an equation to find the value of x:

5x - 26 = 2x + 1 Subtract 2x from each side

5x - 26 - 2x = 2x + 1 - 2x

3x-26 = 1 Add 26 to each side

3x-26+26 = 1+26

3x=27 Divide both sides by 3

3x/3 = 27/3

x = 9

This means that BC = 2x + 1 = 2(9) + 1 = 18 + 1 = 19.

We know that AC = AB + BC; using our given information as well as the value of BC we just found, we have

43 = AB + 19 Subtract 19 from each side

43 - 19 = AB + 19 - 19

24 = AB
