Answer:
Tory=14 Quentin=14
Step-by-step explanation:
Sister and brother same age
s=sister b= brother
s=b
Tory=s+3 Quentin =2b-8 = 2s-8
EQUATION
s+3 = 2s-8
3=s-8
11=s
sister=11 brother = 11
Tory=11+3=14 quentin=2(11)-8 = 22-8=14
1) it's a function 2) for each number 3) set a input and set b output
to be a function, no ordered pairs should have same first coordinate, hence this is a function
Answer:
y=90
x=51
Step-by-step explanation:
square beens right angle; 90 degrees
y=90
90+39
129
180(degrees for straight line)-129
51
x=51
Answer:
Positive Coterminal Angles = 60°,780°
Negative Coterminal Angles = -300°, -660°
Step-by-step explanation:
<h3>
Positive Coterminal Angles:</h3>
To find nearest two coterminal angle of 420°:
1) Subtract 360° from 420°:
420°- 360° = 60° (First Positive Coterminal Angle)
2)Add 360° to 420°:
420°+ 360° =780° (Second Positive Coterminal Angle)
<h3>
Negative Coterminal angles:</h3>
To find nearest two negative coterminal angles of 420°. We' lave to take the value below 0.
1) Substract 360° from 420°
420°- 360° = 60°
Which is still a positive value.
2) Again Substract 360° from 60°
60°- 360° = -300° (First Negative Coterminal Angle)
3)Subtract 360° from -300°
-300°- 360° = -660° (Second Negative Coterminal Angle)
