Answer:

A: Divide both sides of the equation by 4.

Step-by-step explanation:

If you take the equation:

$4y = 3$

And then divide by 4 on both sides (what you do one side you must do to the other):

$\frac{4y}{4} =\frac{3}{4}$

y is isolated.

$y = \frac{3}{4}$

Use the graph to answer the question. Find the slope

Liula [17]

We can take the two points given and plug them into the slope formula.

$\sf~m=\dfrac{y_2-y_1}{x_2-x_1}$

(-3, 3), (1, -5)
x1 y1 x2 y2

$\sf~m=\dfrac{-5-3}{1-(-3)}$

Subtract:

$\sf~m=\dfrac{-8}{4}$

Divide:

$\sf~m=-2$

Write the equation of the line that is parallel to y=-0.75x and that passes through the point (8,0)

Mila [183]

Equation of line parallel to y = -0.75x that passes through (8,0) is: y = -0.75x-6

Step-by-step explanation:

Given equation of line is:

$y=-0.75x$

The coefficient of x is the slope of the line so the slope of given line is: -0.75

As parallel lines have equal slopes so the required equation of line will have the same slope.

The slope-intercept form is:

$y = mx+b$

Putting the value of the slope

$y = -0.75x+b$

To find the value of b, putting the point in the equation

$0 = -0.75(8)+b\\0 = -6+b\\b = 6$

Putting the values of m and b, we get

$y = -0.75x-6$

Hence,

Equation of line parallel to y = -0.75x that passes through (8,0) is: y = -0.75x-6

Tim installs 50 square feet on his floor in 45 minutes. At this rate, how long does it take him to install 495 square feet?

Katena32 [7]

Answer:

445.5 minutes

or 7 hours 25 minutes 30 seconds

Step-by-step explanation:

We can use ratio's to solve

50 ft^2 495 ft^2

-------------- = ------------

45 minutes x minutes

Using cross products

50x = 45*495

50x=22275

Divide each side by 50

50x/50 = 22275/50

x =445.5

445.5 minutes

If we want to convert to hours and minutes, divide by 60

7 hours is 420 minutes

445.5 -420 = 25.5

7 hours 25 minutes

.5 minutes is 30 seconds

7 hours 25 minutes 30 seconds
