Answer:

The value of y is 99

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the line passes through the origin

therefore

Is a proportional variation

Find the value of k

with the point (-2.5,-5.5)

k=y/x=-5.5/-2.5=2.2

The equation is equal to

y=2.2x

so

For x=45

substitute

y=2.2(45)=99

Answer: the value of y is 99

Starting point of the caterpillar = (−2.5, −5.5)

Crawled to the coordinate = (45, y)

y =?

Given that, it crawled in a straight line:

x and y are two variables that are directly proportional to one another  

y/x = k  

Where k is the constant of proportionality since it passes through the origin

-5.5/-2.5 = k  

2.2 = k

So,

y/x = 2.2

So take the coordinate (45,y)

y =2.2 * 45

y  = 99

Hector works 12 hours per week at a part-time
iren [92.7K]

Answer:

b. $2.50

Step-by-step explanation:

Let us take a step by step approach by simplifying each sentence:

Sentence 1: Hector works 12 hours per week at a part-time  hours per week at a part-time job

Number of hours worked per week  = 12hours

Sentence 2:  His original pay rate was $8.00 per hour. but he recently received a raise of x dollars per hour

   Pay per hour is 8hr, a raise of x gives 8 + x

Sentence 3: New total wage  = 12(8+x)

Sentence 4: Amount earned last week  =  $126

  New total wage = Amount earned last week

               12(8 + x ) = 126

                 96 + 12x  = 126

                          12x  = 126 - 96

                           12x  = 30

                             x = $2.50

Amount of raise is $2.50
