Three times a number = 3x
Increased by 8 = + 8
So far we have: 3x + 8
no more than = <=
the number decreased by 4 = x -4
Put it all together and we have:
3x + 8 <= x - 4
Solve for x
3x + 8 <= x - 4
3x - x <= -4 - 8
2x <= -12
2x / 2 <= -12 / 2
x <= -6
-6 is the number / answer.
$640 in interest after 6 months
$8,640 is the balance after six months
No it should be 3,4,5 to make a right triangle
Answer:
0
Step-by-step explanation:
Isolate the variable x. First, distribute 3 to all terms within the parenthesis.
3(2x + 3) = 3(2x) + 3(3) = 6x + 9
6x + 9 = 9
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. First, subtract 9 from both sides.
6x + 9 (-9) = 9 (-9)
6x = 0
Divide 6 from both sides.
(6x)/6 = (0)/6
x = 0
0 is your answer.

Answer:
y=5/3x+b
Step-by-step explanation:
Supposing CD uses the equation y=mb (meaning CD passes through the origin) and passes through (3,5), we then know the slope if 5/3 and the y intercept is 0. We can then write CD's equation as y=5/3x+0, or just y=5/3x.
So if AB is parallel to CB, then their equation is y=5/3x+b, as we don't the y-intercept yet.
Thank you!
