Check the picture below.
they're at a 3:1 ratio, thus, 3 times.
Answer:
see explanation
Step-by-step explanation:
1
x - 4 = 20 ( multiply through by 3 to clear the fraction )
2x - 12 = 60 ( add 12 to both sides )
2x = 72 ( divide both sides by 2 )
x = 36
2
4 =
( multiply both sides by 2 to clear the fraction )
8 = - 1 + x ( add 1 to both sides )
9 = x
3
12(x + 9) = - 108 ( divide both sides by 12 )
x + 9 = - 9 ( subtract 9 from both sides )
x = - 18
4
5x + 14 = - 7 ( subtract 14 from both sides )
5x = - 21 ( divide both sides by 5 )
x = -
= - 4.2
Answer:
y=4
Step-by-step explanation:
First we have to simplify
3r + 2 < 5
subtract 2 from each side then divide by 3
r < 1
7r - 10 > 60
add ten to both sides. divide by 7.
r > 10
answer: r<1 or r>10
if you have to graph, you should have a number line going from 0 to 11. You should put an open circle on 1 and an open circle on 10. Shade to the left from the open circle on 1, and then shade from the right from the open circle on 10.
Your union should look like this:
(-♾, 1)U(10,+♾)
Slope is rise over run. This means your y is over your x. Start with subtracting your y values. It doesn't matter which way, just make sure you do the same with the x values. For this, I'll do it 6 - -9. The two negatives cancel out and make a positive, so your y value is 15. Now, do the same to the x values. -9 - -1 is -8. You're left with 15/-8. Since this can't be simplified, this is your final answer. Hope I helped!
