Answer:

1.) $\frac{(21+21)}{7}$

2.) $(\frac{21+21}{7} )$

Step-by-step explanation:

$\frac{21+21}{7}$

If you just solve it like this, you get 6.

So, the parenthesis would go on the whole thing, or where 21+21 is.

1.) $\frac{(21+21)}{7}$

2.) $(\frac{21+21}{7} )$

Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

$(x,y)\to (-x,-y)$

We know that,

$1260^\circ=1080^\circ+180^\circ$

$1260^\circ=3\times 360^\circ+180^\circ$

After $3\times 360^\circ$ rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

$(7,12)\to (-7,-12)$

The point (7,12) becomes (-7,-12) after rotation of 1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.

10.) The realized income each week is $79.87.
Add both payments and tips then deduct the tax deductions (multiply the rates to the gross income per week).
Gross income per week: (4.70 + 3.85) x 13hrs = 111.15
Tax deductibles: 8.50 (FICA) + 13.67 (federal tax) + 9.11 (state tax) = (31.28)
Realized income per week: 111.15 - 31.28 = 79.87

11.) The value of the stocks in its second year is $1,340.75.
Multiply the investment by the percentage increase, then add the result to the investment. You can also use this formula = investment x (1 + %)
First year: 1,050 x (1 + 0.13) = 1,186.50
Second year: 1,186.50 x (1 + 0.13) = 1,340.75

12.) a. The total value of your stocks after 2 years is $2,046. Use investment x (1 - %) in computing the decreases while investment x (1 + %) in computing the gains.
First year: 2,000 x (1 - 0.07) = 1,860
Second year: 1,860 x (1 + 0.10) = 2,046

b. The balance in your savings account after 2 years is $2,150.74. Use this formula = investment x (1 + rate)^number of years
Balance = 2,000 x (1 + 0.037)^2 = 2,150.74

13.) Your question is incomplete.

5(x + 3)= 4(x -3) What is x?

lana66690 [7]

Answer:

-27

Step-by-step explanation:

5(x+3) = 4(x-3)

5x + 15 = 4x - 12

5x - 4x = -12 - 15

X = -27
