The expression simplifies to 3a-21
Answer:
(-2,1)
Step-by-step explanation:
So we are given f(-3)=1 since the point (-3,1) is on f(x).
We want to use this point to find a point on f(x-1).
Now,
f(-3)=1
and we want
f(x-1)=1
What would x need to be such that x-1 is -3.
x-1=-3
Add 1 on both sides:
x=-3+1
x=-2
x would need to be -2 in f(x-1)=1 in order to use that f(-3)=1.
So (-2,1) is the point for the function f(x-1) that corresponds to the point (-3,1) for f(x).
I know that f(x-1) would only be effecting our input because x-1 is the input.
If b = the number of boys, which alg expression represents the phrase. The sum of the number of boys and 15 girls is b+15.
Always solve equations for such questions using the information provided in the question. Then, as stated in the solution, we may locate the two unknown variables using the two equations that were created.
This kind of question can be answered by assuming any two numbers, x and y, and then applying the condition specified in the question. We know quite well that any equation that can be written in the form ax+by+c=0, where a, b, and c are real integers, and a and b are not zero, is known as a linear equation in two variables. When we apply the condition, we obtain two linear equations with two variables.
Given that the number of boys is b,
Number of girl = 15 girls
Thus the sum of noys and girls is b+15.

I believe it’s 512$
1/4 of 512 is 128
128 * 4 = 512
You can only make 4 liters of lemonade. So that means no.
