Answer:
(3, -2) and (9, 0)
Step-by-step explanation:
x-3(-2)=9
x+6= 9
x=3
9-3y=9
-3y=0
y=0
Answer: -2(f + 5)
Explanation:
I’m assuming you want to figure out what x is in the equation so....
6/8=3/4
2/5=16/40
1/8=5/40
8/10=12/15
I hope this helps.
The measure of an angle is the coterminal angle with a 45A°+360A° and can be determined by using the measurement of coterminal angles.
<h2>We have to
determine</h2>
Which expression finds the measure of an angle that is coterminal with a 45° angle?
<h3>
According to the
question,</h3>
Coterminal angles are those angles that share the terminal side of an angle occupying the standard position.
The standard position means that one side of the angle is fixed along the positive x-axis, and the vertex is located at the origin.
<h3>A
coterminal with 45°
is
45°+k°360° with
k as an
integer.</h3>
Then,
The coterminal angle with 45°,
When k = 0
Then,

When k = 1
Then,

When k = -1
Then,

Hence, The measure of an angle that is coterminal with a 45A°+360A°.
For more details about the Coterminal angle refer to the link given below.

13/21 cause 21 is a common denominator and 7x3+ 21 you have to do 7x=7 and 3x7=21 so you have to do 3x2= 6 so you do 6+7 which equals 13 and your answer is 13 over 21 since it can't be simplified
