Answer:
the two number are 7 and 9
Step-by-step explanation:
2*x+y=25
3x-y = 20
add the two equations
2*x+y=25
3x-y = 20
---------------
5x = 45
divide by 5
5x/5 = 45/5
x = 9
lets find y
2x+y = 25
substitute x
2*9 +y =25
18+y =25
subtract 18 from both side
y = 25-18
y =7
The answer is the third one aka C.
There must not be two points on the same y-axis because that doesn't make a function but a relation instead.
C. doesn't have 2 points on same y-axis and therefore the third picture is the relation that's a function.
8 39/40
=8+39/40
=8•40/40+39/40
=320/40+39/40
=320+39/40
=359/40
=8.975
The answer is 8 39/40=8.975
Answer: Rachel's prediction is faster than the actual unit rate, and Theadore's prediction is slower.
C. 118.2
1 and 2 make a complimentary angle, so 2=118.2
2 and 6 are corresponding, so angle 2=angle 6 (118.2 = 118.2)
