Answer:

2x−5y=12

y = 2/5x + −12/5

Answer is x = 5/2y + 6 because....

First, Add 5y to both sides.

2x − 5y + 5y = 12 + 5y

Then, Divide both sides by 2.

$\frac{2x}{2} = \frac{5y+12}{2}$

Therefor, your answer is going to be x = 5/2y + 6

Answer:

2/5

Step-by-step explanation:

We are given the following equation of a line and we are to tell the slope of the line:

$2x-5y=12$

We know that the standard equation of a line is given by:

$y = m x + c$ where m is the slope of the line.

So re-writing the given equation in the standard form:

$y=\frac{2}{5} x-\frac{12}{5}$

Therefore, 2/5 is the slope of the line.

Lara employed a residential cleaning service to tidy up her home. They charged her $150 for 3

Natalka [10]

Answer:

Step-by-step explanation:

Find the rate that was charged for Lara's time

rate = dollars / hour

The use this rate to calculate how many hours it took to clean Roy's house, since the rates are the same. Solve for hours.....

rate for Lara = dollars / hour = $150 / 3 hour = $50 / hour

rate for Roy = dollars / hour Solve for hours

multiply both sides by hours

(rate for Roy) (hour) = (dollars / hour) (hour)

(rate for Roy) (hour) = (hour) (dollars / hour) right side hours cancel

(rate for Roy) (hour) = (dollars) divide both sides by (rate for Roy)

(rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)

now the rate for Roy on the leftside cancel

(rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)

(hour) = (dollars) / (rate for Roy) Plug in $225 charged to Roy

and the $50 / hour rate

hour = $225 / ($50/hour) ( 1 over 1 / hour ) = hour

= $(225/50) hour think about 1 / (1/2) = 2 the same with units

hour = 4.5 hours

Plssss answer… for math

Greeley [361]

Answer:

Graph A is a function, and Graph B is not

Step-by-step explanation:

A function is when each x-value (aka input) has 1 corresponding y-value (or output).

We see that graph 1 is linear, and that each x-value has it's own y-value, and not multiple y-values.

However, Graph B curves, making it so some of the x-values have more than 1 y-value.

George had $6,000 in a savings account earning simple interest at a rate of 5% per year. At the end of the year, George paid 25%

Readme [11.4K]

Answer:

$225

Step-by-step explanation:

Given that:

Principal = $6,000

Interest rate = 5%

Time = 1 year

Taxes paid = 25% on the interest earned

To find:

Money earned after paying taxes ?

Solution:

First of all, let us calculate the total interest earned:

Formula for Simple Interest is given as:

$SI =\dfrac{PRT}{100}$

Where P is the principal

R is the rate of interest

T is the time taken

Putting the given values:

$SI =\dfrac{6000 \times 5\times 1}{100} =\$300$

Now, it is given that 25% of the interest earned is given as taxes.

Taxes paid = 25% of $300

$\Rightarrow \dfrac{25}{100} \times 300 =\$75$

Therefore, the money earned = Interest earned - Taxes paid

The money earned = $300 - $75 = $225

What is one of the solutions to the following system of equations? y2 + x2 = 53 and y − x = 5

Aneli [31]

Y2 + x2 = 53
y − x = 5
y = 5 + x

(5+x)^2 + x^2 = 53
(5+x)(5+x) + x^2 = 53
25 + 10x + x^2 +x^2 = 53
2x^2 + 10x - 28 = 0
(x-2)(x+7)=0
x = 2 , x = - 7

y = 5 + 2
y = 7

y = 5 +(-7)
y = 5 - 7
y = - 2
