Answer:
f(x)=15
D
Step-by-step explanation:
f(x)=x2+5x-9
f(3) means to substitute 3 for x in the equation.
3^2+5(3)-9
9+15-9
f(x)=15
y=mx+b
b is the y intercept, so changing it to -1 would shift the line down 2 units. you
Answer:
4.43 inches
Step-by-step explanation:
The volume of the hot tub is
V = l*w*h
We are given the volume in gallons which we need to convert to cubic inches
1 gallon = 231 in^3
350 gallons *231 in ^3/1 gallon = 80850 in ^3
Substituting in what we know, we can find the height of the tub
80850 = 76*60 *h
17.76026316 is the height of the tub
If the tub is 1/4 full
We take 1/4 of the height
1/4 * 17.76 = 4.432565789
The approximate height of the water is 4.43 inches
Answer:
Step-by-step explanation:
Eliminating parentheses, you get ...
-2bx +10 = 16
Subtract 10 and divide by -2b:
x = 6/(-2b)
x = -3/b
__
When b=3, you have ...
x = -3/3
x = -1
64 , it's doubling every time
On a standard die, or number cube, there are six faces, each with a number one through six written once. Five is written only once on here, so the odds of rolling a five are one in six. Thus, the odds of not rolling a five are five in six.
