1400+ 900x= 4100
Subtract 1400 from each side
900x= 2700
Divide each side by 900
X= 3
It needs to eat 3 mosquitos each hour
Answer:
D. (3, -1).
Step-by-step explanation:
The vertex for ( x - a)^2 + b is (a, b).
Comparing (x - 3)^2 - 1 with this we get:
a = 3 and b = -1.
There is an X intercept at x=-8
There is a y intercept at y=4 (0,4)
Answer: 5
Slope is usually the number in front of x
2x^2 - 11 = 87
2x^2 = 87 + 11 = 98
x^2 = 98/2 = 49
x = sqrt (49) = + or - 7
