Answer:
x = 10.73
Step-by-step explanation:
Answer: x
=
6
Explanation:
the initial statement is
x
∝
1
y
to convert to an equation multiply by k the constant
of variation
⇒
x
=
k
×
1
y
=
k
y
to find k use the given condition
x
=
4
when
y
=
9
x
=
k
y
⇒
k
=

Step-by-step explanation:
Answer:
B. y-7 = 1/2(x+3)
Step-by-step explanation:
The coordinates in the question must be inverted (so -3 would become +3 and +7 would become -7)
We know that the line would be perpendicular when (x+3) is preceded by -2
You can double check this by going to a website that graphs equations and overlapping the lines.
The answer is 70 because angle CGA is a 90° angle and it is split into two. so if one part of it is 20°. 90-20 equals 70°
