Answer:
x=-3
Step-by-step explanation:
2x (x + 4) -12x
2×-3(-3+4)-12×-3
-6(1)+36
30
Answer:
x = 10
Step-by-step explanation:
1) Subtract x from both sides.
4x − x = 30
2) Simplify 4−x to 3x
3x = 30
3) Divide both sides by 3
x = 
4) Simplify
to 10
x = 10
You’d rewrite it in slope-intercept form, y=mx+b
So the answer is y=-5/3x+10
Then you can point out the slope and y-intercept after you put it in the form.
Slope = -5/3
Y-intercept = 10
Hopefully this helps!
Answer:
i think D is the correct answer
Step-by-step explanation:
Answer:
Equation: 3x + 7 = 16
Unknown Number: 3
Step-by-step explanation:
You must first develop an equation representing this problem:
3x + 7 = 16
Then, you can solve for the unknown number.
3x + 7 = 16
3x = 9
x = 3
