Answer:
1. C
2. C
Step-by-step explanation:
1. x =
, y = 4t +3
Solve for t:
t =
Plug in t:
y = 4(
) +3
y = 4
+3
2. x = 2t, y = t + 2
Solve for t:
t = x/2
Plug in t:
y = 1/2x + 2
so hmmm on average on the last 7 test, you get 82, so hmmm we could say that on each of the 7 tests you got 82, so you got 82, 7 times.
now, let's say in the 8th test, you get a grade of "g", now, if we were to get an average of all 8 tests, that means the average will simply be (82*7) + "g", and we know that's 84, so

Answer:
x = 1
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 12 when x = - 2, then
k =
=
= - 6, thus
y = - 6x ← equation of variation
When y = - 6, then
- 6 = - 6x ( divide both sides by - 6 )
x = 1
