How do you solve: 0.5((31-x)-(3x+4))=9

Hi there!

To solve this problem, we need to simplify the values inside the parenthesis first.

0.5 (31 - 4 - x - 3x) = 9
0.5 (27 - 4x) = 9

Now, we distribute the 0.5 into the parenthesis:

0.5*27 - 0.5*4x = 9
13.5 - 2x = 9

Now, we subtract 13.5 from both sides:

-2x = 9 - 13.5
-2x = -4.5
2x = 4.5

And solve for x.

x = 2.25

Hope this helps!

Naomi deposited money into savings account that is compunded quarterly at an interest rate of 6%. She thinks this quarterly rate
FromTheMoon [43]

Answer:

No, because 1.25% times 3 is 3.75% which is less than 6%

Step-by-step explanation:

Quarterly is every 3 months

6% interest is 1.06, 6 cents on the dollar

Monthly interest rate is 1.25% so 1.25 × 3 is 3.75

So, 1.25% times 3 is 3.75% which is 2.25% less than 6%

Hope this helps!

Have a great day!

Select the correct answer Which equation represents a line that is perpendicular to line MN?
taurus [48]

Answer:

D. y = 4x - 6

Step-by-step explanation:

The equation that is perpendicular to the line MN should have a slope that when multiplied by the slope of line MN will result to negative one. Therefore,

Therefore,

m₁ × m₂ = -1

Using the 2 coordinates of MN let's find the slope,

(-7, 6)(5, 3)

Therefore,

m₁ = 3 - 6 / 5 - (-7) = -3 / 12 = - 1 / 4

The equation that represent a line perpendicular to the line MN is

y = 4x - 6 because the slope slope(m₂) is 4.

From our formula,

4 × - 1 / 4 = - 1

So, option D meets the requirement.
