Which expression finds the measure of an angle that is coterminal with a 126° angle?A. 126° + (275n)°, for any integer n
B. 126° + (375n)°, for any integer n
C. 126° + (450n)°, for any integer n
D. 126° + (720n)°, for any integer n

Answers

The expression that gives an angle that is coterminal with 126 is 126 + 720n. Two angles are said to be coterminal if when they are drawn in a standard position, their terminal sides are on the same location. The expression will give an angle which when it is drawn the terminal sides are on the same location with the 126 angle.

The option (D) 126° + (720n)°, for any integer n is correct for any integer n.

What is coterminal angles?

Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have an angle of 126 degree

As we know from the definition of the coterminal angle.

If any angle θ the coterminal angles are:

= θ + 360n (for any integer n)

Plug n = 2n

= θ + 720n (for any integer n)

Also represents the coterminal angle.

Thus, the option (D) 126° + (720n)°, for any integer n is correct for any integer n.

Which equation could be used to solve y 2+7y=18 by factoring?

Answers

For this case we have the following equation:

$y ^ 2 + 7y = 18$

Rewriting the equation we have:

$y ^ 2 + 7y-18 = 0$

Then, we must factor the equation:

We are looking for two numbers that are equal to 7 and multiplied equal to -18.

We have then:

$(y + 9) (y-2) = 0$

Answer:

An equation that could be used to solve $y^2 + 7y = 18$ by factoring is:

$(y + 9) (y-2) = 0$

(y + 9)(y - 2) = 0 would be the correct answer .

Janet invested $10,000, part at 2% and part at 12%. if the total interest at the end of the year is $600, how much did she invested at 2%

Answers

Janet invested $6000 at 2 %.

Let x = amount invested at 2 %. Then 10 000 - x = amount invested at 12 %

interest at 2 % + interest at 12 % = 600

0.02x + 0.12(10 000 – x) = 600

0.02x + 1200 – 0.12x = 600

0.10x = 600

x = 600/0.10 = 6000

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

Answers

If you want to find how the graphs of the functions for the two months are similar and how they are different, here is the answer:

Both are straight lines.
Both slopes are the same.
The x and y intercepts are different.

Hope that helps :)

Answer: y = -2/3x + 490

Step-by-step explanation:

2x +3y = 1470

Slope intercept form definition: y = mx + b is the slope-intercept form of a line where m is the slope and b is the y-intercept.

2x + 3y = 1470

2x + 3y -2x = 1470 - 2x - Subtract 2x from both sides

3y = 1470 - 2x - Simplify

3y/3 = 1470/3 - 2x/3 - Divide both sides by 3

y = -2/3x + 490 - Simplify

-⅔ is the slope and 490 is the y-intercept
