I will show you how to do the first one.....we are finding the GCF...the largest number that goes into each number (same for variables)

1.) 20yx , 80x³ ( factor each number and variable)

20 = 2, 4, 5, 10, 20
y = y
x = x
80 = 2, 4, 5, 8, 10, 16, 20, 40, 80
x³ = x, x, x

what is the largest number that 20 and 80 have in common? 20...
how about the variables? x

so, the Greatest Common Factor (GCF is 20x)

This question made me stuck lol.. I really need help

(4,5)(2,1)
slope = (1 - 5) / (2 - 4) = -4/-2 = 2

(-2,3)(-4,4)
slope = (4 - 3) / (-4 - (-2) = 1/(-4 + 2) = -1/2

2 and -1/2 are negative reciprocals of each other....therefore, ur lines are perpendicular <==

A pyrotechnician plans for two fireworks to explode together at the same height in the air. They travel at speeds shown below. F

Anastasy [175]

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
By the time firework a has been launched, firework b has already been launched for 0.25 seconds, so if we treat the two as equations, then

a = 220 (t)
b = 220 (t) + 220 (.25)

And we want to know when these two equal eachother, as that's they will both detonate.

220t = 200 t + 200 (.25)
20t = 50
t = 2.5

10 girls go to see a chick flick together on a friday night at their local megaplex. they buy x large popcorns and y large fount

Natali [406]

Answer:

They had 4 large popcorn and 10 large fountain drinks

Step-by-step explanation:

The picture of the question in the attached figure

I think the price of the large popcorn is $7.50 and the price of the large fountain drink is $5.50 (The picture is not clear)

Let

x ----> the number large popcorns

y ----> the number of large fountain drinks

we know that

$x+y=14$ ----> equation A

$7.50x+5.25y=85$ ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (4,10)

see the attached figure

therefore

They had 4 large popcorn and 10 large fountain drinks
