Answer:
y = 2x + 7
Step-by-step explanation:
→ Find the gradient
→ Write into y = mx + c format
y = 2x + c
→ Substitute in x = -1 and y = 5
5 = -2 + c ∴ c = 7
→ Write into y = mx + c format
y = 2x + 7
Answer:
ŷ = 0.46x + 41.89
Step-by-step explanation:
1/4
This is because he only spent 3/4 of an hour and there are 3 groups already. So they each got a fourth of the time.
Answer:
1.2
Step-by-step explanation:
The point on the graph (- 6, 1.2 ) gives the value of f = 1.2 when x = - 6
Then when x = - 6, the output f = 1.2
Answer:
Step-by-step explanation:
If you are solving x then do this:
-2.3-5=x-17
First combine like term.
-7.3=x-17
Then add each side of the equation by 17 (we aren't subtracting because we are trying to get rid of -17 so to get rid of it we add by 17).
-7.3 +17 = x-17+17
9.7=x
