So Roger flight left at exactly 9.27:am and it will land at 1:05pm
So count on to 12:27 will be 3 hours and subtract from 5 because 65 is 05 3hours and 38mins

Steps:
I will try to solve your system of equations.

Step: Solve
3
x

y
=
21
for y:
3
x

−
3
x
=
21
+
−
3
x
(Add -3x to both sides)
−
y
=

3
x
+
21
−
y
−
1
=
−
3
x
+
21
−
1
(Divide both sides by -1)
y
=

21
for
y
in

17
x
−
105
=
−
3
(Simplify both sides of the equation)
17
x
−
105
+
105
=
−
3
+
105
(Add 105 to both sides)
17
x
=
102
17
x
17
=
102
17
(Divide both sides by 17)
x
=
6
Step: Substitute
6
for
x
in
y
=

y
=

(Simplify both sides of the equation)
Answer:
y
=
−
3
and
x
=
6
Answer:
See explanation.
Step-by-step explanation:
- A terminating decimal is a decimal that has an end.
- A repeating decimal is a decimal fraction in which a number, or a group of numbers, is repeated indefinitely.
- Most repeating decimals contain a nine in the denominator, when written in fraction form.
- Both can be written in fraction form.
- Both can have a positive or negative value that can be both large and small.
Answer: y= 3/5x+1
Step-by-step explanation: if you want to check if its perpendicular go on Desmos graphing calculator on goolge and plug both equations:)
