A line has a y-intercept and a slope of 0. What is the line’s equation?

1 answer:

6 0

The answer is y= -1

When the slope is 0, we refer to the line as a constant function. In slope intercept form, the line is equal to y = mx + b

"m" is the slope, and "b" is the y-intercept.

Let's replace those in the function.

y = 0*x - 1

0 multiplied by anything is 0

y = 0 - 1

y = -1

The length of a rectangle is 6 centimeters less than twice its width. The perimeter of the rectangle is 48 cm. What are the

fomenos

Answer:

the length is 12 and the width is 9.

Step-by-step explanation:

The first step is always to assign letters to the variables. We can call length L and width W.

Since all units are in cm, unit conversion is unnecessary.

Next, set up some equations. L=2W-6 because of the first sentence of the problem. Length times width equals area, so L*W=108.

Now that there are two equations and two variables, the next step is to solve the system. I'm going to solve it by plugging in the right side of the first equation in for L in the second equation. This gives me (2W-6)*W=108. Distributing the W gives me 2W^2-6W=108, or W^2-3W-54=0. Using the quadratic formula, I get that W=9. Using the first equation, L=2*9-6=12. So the length is 12 and the width is 9.
