Answer:

coincident

Step-by-step explanation:

The first equation is 3 times the second equation, so describes exactly the same line. The lines are "coincident".

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

Substitue y=3x+2 to the y in y=x+10.
3x+2= x+10

Subtract 2 to both sides.
3x=x+8

Subtract x to both sides.
2x=8

Divide both sides by 2
2x/2 = 8/2

You are left with x = 4

Choose one equation and replace x by 4.
y = (4) + 10
y= 14

Now, you have x = 4 and y= 14. So, your ordered pair is (4,14) because both lines pass through that point.

If you do not want to do this solution, I suggest you graph it using the slope.

What is the answer to 6/2(1+3)?

Kaylis [27]

Use PEMDAS to figure out which expression to work out first:

Parentheses
Exponents
Multiplication/Division
Addition/Subtraction

First, we'll want to solve the term with parentheses:

$2(1+3) = 2(4) = 2 \times 4 = 8$

The equation should now look like this:

$6 \div 8$

Divide to get your answer:

$6 \div 8 = 0.75$

The answer is 0.75.
