Two lines, C and D, are represented by the equations given below:

1 answer:

4 0

Given:
line C: y = x + 14
line D: y = 3x + 2

(6,20) or (3,11)

line C: y = 6 + 14 = 20 or y = 3 + 14 = 17
line D: y = 3(6) + 2 = 18 + 2 = 20 or y = 3(3) + 2 = 9 + 2 = 11

(6,20), because both lines pass through this point.

What does this equal to? 8ft 12 in. = ____yd

MissTica

First:
3 feet=1 yard
36 inches=1 yard

8 feet=2 $\frac{2}{3}$ of a yard
12 inches=1/3 of a yard.

2 $\frac{2}{3}$ + $\frac{1}{3}$ =2 $\frac{3}{3}$ or 3.

Hope this helps!

What is the answer to factorise 3D+12

gizmo_the_mogwai [7]

Well it should be like this tell me if im wrong, ↓

3D + 12
___ ___

3 3

so, hypo thinking once 3 is divided should leave you with . ↓

D = 4 cause once you do all the cancellations it basically leads 2 D then you have to divide →→ 12/3 → 3·4 or 4·3 either way it equals 12 sooo just do the math and you will come up with ...............................↓

-Hope this helped you any if not so comment right answer D=4 :)

X –12 = -8x + 6 a.x = 2 b.x = -2 c.x = 3 d.x = -3

Naddik [55]

Answer:

(a) x = 2

Step-by-step explanation:

x - 12 = -8x + 6

First, move all the like terms to one side of the equation. We will move all the x's to the left, and the rest to the right in this equation. (Don't forget to pay attention to the signs of the numbers as you move them over the equal sign.)

x - 12 + 8x = 6

x + 8x = 6 + 12

9x = 18

Next, solve for x by isolating it to one side of the equation. Here, we'll have to divide 18 by 9 (do the opposite of what 9 is doing with x; instead of multiplying it with 18 like it currently is with x, divide 18 by it.)

x = $\frac{18}{9}$

x = 2

Therefore, your answer is (a), since x = 2.

I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!
