Answer:
8x-7y=-25
Step-by-step explanation:
It's a matter of substituting the x and y values into the equations
so basically trial and error
I used the set of points: (-4, -1)
(8 x -4)-)7 x -1) = -25
30m x 7e = 210m
Just multiply the number of minutes by days of a week, so it'd be 30 x 7 to get 210 minutes.
Step-by-step explanation:
it is not drawn correctly
it only has to be 4 not 3
Answer: f(3) = 23
Step-by-step explanation:
Put 3 where x is in the expression for f(x) and do the arithmetic.
... f(3) = 2·3^2 +5√(3-2)
... f(3) = 18 + 5 = 23
