Can some explain steps​
Mashutka [201]

Answer:

r = 3.

Step-by-step explanation:

16 = 10 + √(3r + 27)

√(3r + 27) = 6

Square both sides:

3r + 27 = 36

3r = 36 - 27 = 9

r = 3.

Check the result:

Left side of the equation = 16

Right side = 10 + √(9 + 27)

                  = 10 + √36 = 16

The amount Lin's sister earns at her part-time job is proportional to the number
jarptica [38.1K]

the equation framed in the form of y=kx is  y = 9.6(x) and ,  x as a function of y x=\frac{1}{ 9.6}(y) .

<u>Step-by-step explanation:</u>

Here we have , The amount Lin's sister earns at her part-time job is proportional to the number  of hours she works. She earns $9.60 per hour. We need to find  an equation in the form y=kx  to describe this situation, where x represents the hours she works and y  represents the dollars she earns.Is y a function of x . Also , Write  an equation describing x as a function of y . Let's find out:

Here , Lin's sister earns $9.60 per hour . Let  x represents the hours she works and y  represents the dollars she earns . So , According to question following is the equation framed in the form of y=kx :

⇒ y = 9.6(x)

Yes, y is a function of x , as a straight line with a slope of 9.6

Now ,  x as a function of y :

⇒ \frac{y}{ 9.6}=(x)

⇒ x=\frac{1}{ 9.6}(y)

Therefore , the equation framed in the form of y=kx is  y = 9.6(x) and ,  x as a function of y x=\frac{1}{ 9.6}(y) .

Which of the following is a correct equation for the line passing through the
kipiarov [429]

Answer:

2x-3y=-12

Step-by-step explanation:

We can use the point-slope formula given by:

y-y_1=m(x-x_1)

The given line passes through the

point (-3,2) and having slope m=\frac{2}{3}.

We substitute the given point and slope to get:

y-2=\frac{2}{3}(x--3)

y-2=\frac{2}{3}(x+3)

we clear the fraction to get;

3y-6=2(x+3)

3y-6=2x+6

3y-2x=6+6

3y-2x=12

Or in standard form:

2x-3y=-12
