Any help? On the graph of the equation x − 4y = −16, what is the value of the y-intercept? (1 point)

1 answer:

5 0

The answer is 4 because when you move the -4y to the right side of the equal sign, it becomes a positive. and whatever number is next to the Y variable is the Y intercept.

To own and operate a home printer, it costs $100 for the printer and an additional $0.05 per page for ink. To print out pages at

Softa [21]

Answer:

1.) 500 pages

2.) $125

Step-by-step explanation:

Given that the printer cost $100. To operate at home will cost

100 + 0.05P

To print out pages at an office store, it will cost 0.25P

1.) For the costs to be the same, then

100 + 0.05P = 0.25P

0.25P - 0.05P = 100

0.20P = 100

P = 100/0.2

P = 500 pages

500 pages need to be printed

2.) How much does it cost to print that many pages?

Cost = 0.25P

= 0.25 × 500

= 125 dollars

In JKL, mJ = 90, mK = 30, and mL = 60. Which of the following statements about JKL are true?

kumpel [21]

The <em><u>correct answers</u></em> are:

KL = 2*JL; JK = (√3)JL; and JK = ((√3)/2)KL

Explanation:

This is a 30-60-90 right triangle. This type of triangle has a special relationship among the sides. Let the smallest side, across from the 30° angle, be t. This means JL = t.

The hypotenuse of the triangle is two times the length of the smallest side; this means that KL = 2t, which means that KL = 2*JL.

The side of the triangle opposite the 60° angle will be the "medium sized" side; it is equal to √3 times the smallest side, or √3t; this gives us that JK = √3t = (√3)JL.

Comparing JK to KL, we have

$\frac{t\sqrt{3}}{2t}$

The t on top and bottom cancel out, leaving us with the ratio (√3)/2. This means that JK = ((√3)/2)KL.
