X intercept= -4

8.9 slope=1

Y intercept= 2

X intercept= -2

Step-by-step explanation:

compare the equation with the standard equation Y= MX + C

Malia works at a movie theater and is paid hourly. One month, she earned $388.80. The total amount she earns can be found using
AlekseyPX

Answer:

Malia's unit rate is greater than Bill's by $0.05.

Step-by-step explanation:

Consider the provided information.

The total amount she earns can be found using the equation y = 8.1x, where x is the number of hours she works and y is the total amount she earns in dollars.

The unit rate, when written as a fraction, has a denominator equal to one.

The unit price of Malia is $8.1

For Bill works:

Number of hours Total amount earned

18 $144.90

28 $225.40

35 $281.75

Unit price would be:

\begin{gathered}\dfrac{144.90}{18}=\dfrac{y}{x}\\\\8.05=\dfrac{y}{x}\\\\y=8.05x\end{gathered}

18

144.90

=

x

y

8.05=

x

y

y=8.05x

Hence, unit price of Bill is $8.05

Malia's unit rate is 8.1 whereas Bill's unit rate is 8.05,

Thus, Malia's unit rate is greater than Bill's by 8.10-8.05=0.05.

Three friends bought 4, 6, and 8 books. The table shows the cost of the books.
Pepsi [2]

Answer:

Option (B) is correct .

The constant of proportionality is 7.5 .

Reason

Let us assume that the number of books be x.

Let us assume that the cost of books be y .

Than

y \propto x

y = kx

Where k is constant of proportionality .

As given

Number of Books 4 6 8

Cost ($) 30 45 60

Thus

when x = 4 , y = 30

Put in the equation y = kx .

30 = 4k

k = \frac{30}{4}

k = 7.5

when x = 6 , y = 45

Put in the equation y = kx .

45 = 6k

k = \frac{45}{6}

k = 7.5

when x = 8 , y = 60

Put in the equation y = kx .

60 = 8k

k = \frac{60}{8}

k = 7.5

Therefore the constant of proportionality is 7.5  i.e option (B) is correct .
