For question 3, the answer is f(x)=3x-4.
In question 3, if -7 is f(x), and it is 3x-4, the answer is -1; if -7 is f(x), and the answer is 4x-3, the answer is -1; if -7 is f(x), and it is 1/2x+3, answer is -20; if -7 is f(x), and it is 3x+1/2, the answer is -5/2.
But, if -4 is f(x), and it is 3x-4, the answer is 0; if -4 is f(x), and it is 4x-3, the answer is -1/4.
So f(x)=3x-4 is the answer for question 3.
For question 4, the answer is the last choice.
Like the one above 3x was the rate and -4 is the initial value.
So for this one, 2/3 is the rate and -2 is the initial value.
Answer:
17852.5$
Step-by-step explanation:
I already answer this in another part, but here it is againa:
In this case, all you need to do is sum all the amounts and take out the down payment of 2500$
First, the car of 18,500 with the 6.5% sale tax, it would be:
18,500 * (6.5/100) = 1202.5$
18500 + 1202.5 = 19702.5$
Now the charge and fees:
450+155+45 = 650$
Then:
19702.5 + 650 = 20352.5$
Finally, the down payment:
20352.5 - 2500 = 17852.5 $
I assume you are referencing y=mx+b. The equation gives you the slope of the line (m), and a coordinate (x, y). As well as b, which could be used for many things.
Answer:
y = -2x + 8
Step-by-step explanation:
y = mx + b
-8 = -2(8) + b
-8 = -16 + b
8 = b
y = -2x + 8
Answer: It flies 108 miles in 3 hours.
Step-by-step explanation:
576/16 = 36
It flies 36 miles per hour
36 * 3 = 108
