Answer:
13
Step-by-step explanation:
because a is the missing number. Well, 21 minus or - 8 is equal to 13.
The inequality is 7x + 21 
Step-by-step explanation:
<u>DATA:</u>
Let the number be x
Number times 7 = 7*x
Sum of a number times 7 and 21 = 7x + 21
Is at least 29
<u>INEQUALITY:</u>
7x + 21 
<u>SOLVE:</u>
7x
7x
x 
Therefore, the inequality is 7x + 21

The new shower head dispenses 3 gallons of water per minute, as shown in the equation y = 3x.
So, 3 x 8 = 24.
Then, to find out how much he saves each day, you would find how much he used before,
11 x 8 = 88
Next we want to see how much Nathan saved, so we subtract the total,
88 - 24 = 64
Nathan saved 64 gallons.
Answer:
f(x)=-2x+9 g(x)=-4x^2+5x-3Now, f o g (x) = f{g(x)} = f(4x^2+5x-3) = 2(4x^2+5x-3) + 9 = 8x^2+10x-6 + 9

Answer:
Choice B.
Step-by-step explanation:
We can eliminate each graph:
a). This is what is known as a step function. This is incorrect.
b). This is an exponential function because the graph is shaped like a geometric equation. This means that the rate of change is exponential. This is the correct choice.
c). This is an absolute value function. This is incorrect.
d). This is a graph of a polynomial. This does not represent an exponential function, which makes it incorrect.
