Graph the line with slope 1/4 and y-intercept -8
kherson [118]

Solution: Below! ^^

Detailed explanation:

Hii! I'm sorry, I can't graph the line for you, but I'll try to give you the best possible explanation.

First, note that the question provides us with the info that the y intercept is -8. This is a very valuable piece of information!

This means that the line crosses the y axis (since it's the y intercept) at the point (0,-8). Plot it on the co-ordinate plane.

Next, this question also provides us with the fact that the slope of the line is 1/4. This is yet another valuable piece of information!

What this tells us is: from that point (0,-8), you need to go up 1 unit, then over 4, and so forth, until you obtain a line.

Hope I helped, best wishes & happy studies!

What is the answer a factory adds three red drops an two blue drops of coloring to white paint to make each pint of purple paint
Elan Coil [88]

Answer:

Red = 30 drops

Blue = 20 drops

Step-by-step explanation:

The ratio red to blue is 3 : 2

Sum of ratios = 3 + 2 = 5

Required purple paint = 50 gallons

So,

Multiplier = \frac{50}{5} = 10

Now, Red drops = 3×10 = 30

Blue drops = 2×10 = 20

In ΔOPQ, the measure of ∠Q=90°, PO = 97, OQ = 65, and QP = 72. What is the value of the tangent of ∠O to the nearest hundredth?
garri49 [273]

Answer: 1.11

Step-by-step explanation:

with tangent I guess A+B=C, B goes over A. But like I bet you're wondering how will yk which is a or b? idk either, but I tried my luck and got it right. So yk how C (hypotenuse) is always the biggest number? Well whichever number is bigger (A or B) the bigger number will go over the smaller one and then you round it to the nearest hundredth. I'm not good at rounding, so I used Math//way to get it for me. So it could be like , 12+36=40 (just picking random numbers), 36 will go over 12. And then you round it. I hope thus makes sense, it's 5:40AM rn. I should be sleep  because I have a job interview at 3PM today.
