Answer:
<em>x = 3</em>
Step-by-step explanation:
Step 1:
Subtract 1 from both sides
2x + 1 = 7
2x + 1 - 1 = 7 - 1
<u>2x = 6</u>
(1 - 1 will cancel itself out on the side with the variable.)
Step 2:
Divide both sides by 2
2x = 6
2x ÷ 2 = 6 ÷ 2
<u>x = 6 ÷ 2</u>
(2 divide by 2, will cancel itself out on the side with the variable.)
Step 3:
Solve for x
6 ÷ 2 = 3
x = 6 ÷ 2 = 3
<u>x = 3</u>
Answer:
c
Step-by-step explanation:
cwvw
5(x+4)=-15
Distribute
5x+20=-15
Subtract 20 from both sides
5x=-35
Divide both sides by 5
x=-7
Final answer: The number is -7
The answer is 0.65. I hope this helps!
Nope. its y=3x-1. the y intercept is -1, so we put that at the end. And if we take 2 points on the line and use y/x, we get 3/1 or 3, and this is our slope. Also the line is going up so its not negative
