Y=2X

Looking at the line you can see that it is moving up from left to right, making it positive. So -2X and -12X are incorrect.

Next we can find the slope by putting rise over run. Chose a point on the line, I’ll use (2,4).
On this point we rise to 4 and run over to 2.
So for rise over run we have 4/2 which is 2.
So y=2x is correct.

Collin is building a deck on the back of his house. He has enough lumber for the deck to be 144 square feet. The length should b

joja [24]

Width = x
length = x+10

Area of deck = 144 square feet

Area = length * width

144 = x(x+10)

Solving for x in a quadratic:

x²+10x = 144
x²+10x-144 = 0

Factor:
(x+18)(x-8) = 0

Solving for x:
x = 8, x = -18

Dimensions cannot be negative, therefore x = 8, only.

Length = x + 10
Length = 18

Width = 8

I must also show my work, but I do not know how to do this problem

Vinvika [58]

Answer:

x = 10

Step-by-step explanation:

We know that the sum of angles in a triangle is equal to 180 degrees;

This means that

71+50+(6x-1) = 180; now that you have an algebraic expression, you can solve for x.

71+49+6x=180

120+6x = 180

6x = 60

x = 10
