36, because the square root of 4 is 2 and the square root of 81 is 9. You multiply those and then double it to get 36.
Answer: y=-1x+5
Step-by-step explanation:
1. Use slope-intercept formula (y = mx + b) to find the slope which is represented by the variable 'b'.
m = ∆y / ∆x
m = -1 / 1
m = -1
y= -1x + b
2. Use any cooresponding x and y values to substitute into the formula. Ex: (x,y) → (1,4)
y = mx + b
4 = -1(1) + b
4 = -1 + b
5 = b
3. Plug in the values found into the formula.
y = -1x + 5
Answer:
15 bags
Step-by-step explanation:
25 * 18 yard^2 = area
so, Area/Fertilizercoverrate = what we want.
25*18/30 = <u><em>15 bags</em></u>
Answer:
Its 8
Step-by-step explanation:
B. Up
Because a positive ‘a’ value will make the parabola open upwards, and because the power is 2 (even) both sides will open up in a ‘U’ shape
