So, you need to know that the slope stays where it is, and that the 6 is not part of the final answer, so get rid of it.
y=2x+b
Now, submit x in for x, and y in for y.
3=2(1)+b
3=2+b
1=b

Put this in for the equation missing the b,
y=2x+1
Now check it; if you put 1 in for x, does y=3?

Find the value of x. Then find the measure of each interior angle. Show work algebraically
OleMash [197]

Answer:

Step-by-step explanation:

W=180-144

W=36 degrees

The sum of angles in a triangle always sum to 180 degrees.

6x+1+7x+36=180

13x+37=180

13x=143

x=11

U=6x+1

U=6(11)+1=67 degrees

V=7x

V=7(11)=77 degrees so

x=11 degrees, U=67 degrees, V=77 degrees, and W=36 degrees.

Explain why you should proform the distributive property in the expression 4x+3(2x+1) before simplifying it any other way. Then
Anna71 [15]
You use the distributive property to simplify expressions.

4x+3(2x+1)

2 times 2x is 6x
3 times 1 is 3
4x times 2x is 8x
4x times 1 is 4x

total that is 6x+8x+4x+3=18x+3

Hope it helps!
