The answer is D. f(x) = 3x+2

This is because this is the ONLY function equation that works for ALL of the ordered pairs listed in the table

-4 = 3(-2) + 2
-4 = -6 +2
-4 = -4

-1 = 3(-1) +2
-1 = -3 +2
-1 = -1

2 = 3(0) + 2
2 = 0 + 2
2 = 2

5 = 3(1) + 2
5 = 3 + 2
5 = 5

8 = 3(2) +2
8 = 6 +2
8 = 8

In a crayon box there are 5 dark colors for every 8 light colors. If there are 20 dark colors, how many light colors are there.

Answer:32

Step-by-step explanation:

Since 5 dark colors are equal to 8 light colors, see how many times 5 goes into 20. 20/5=4. So now multiply 8 with 4. 8x4=32.

Factorise x^12 y^4 - x^4 y^12<br><br>PLEASE PLEASE explain in step by step Pleasseeeeee

QveST [7]

Answer:

Step-by-step explanation:

First, look at your terms. You have two terms and two variables in each. So they can be factored out because you can distribute them back in easily.

Focus one variable first, x. You cant factor an x^12 out of an x^4. You can, but you really don't want to, it'll turn your problem into a mess. So the only thing you can do is factor out the lower exponent, x^4.

$x^4(x^8y^4-y^1^2)$

We arent done yet because the terms still share the y variable. You cant factor a y^12 from a y^4. This is the same problem with the x variable. So take out the lower one, y^4.

$x^4y^4(x^8-y^8)$

Answer:

(i) ∠CDF = 86°

(ii) ∠BAD = 141°

Step-by-step explanation:

(i) Angles CDF and GFD are "alternate interior" angles, so are congruent.

∠CDF = 86°

(ii) Angles BAD and CDA are "alternate interior angles, so are congruent. Angle CDA is the sum of angles CDH and HDA. Angle CDH is supplementary to angle CDF, so is ...

∠CDH = 180° -∠CDF = 180° -86° = 94°

Then ...

∠CDA = ∠CDH +∠HDA = 94° +47°

∠CDA = 141°
