The correct answer for this question is this one: "The location (x, y) where the lines intersect is a solution to a system of equations." <span>This is the explanation that is an accurate way to describe the solution to a system of equations by using a graph. </span>Hope this helps answer your question and have a nice day ahead.
Since it is 40% OF 45 you have the whole and percent so multiply 45 by 40 then divide by 100 you get 18
Answer:
C
Step-by-step explanation:
C is the only viable answer, because it it the only one that decreases as x approaches infinity. Exponential decay decreases, hence the decay part.
1) a. x = number of cars
b. x - 12
2) a. x = number of packages
b. 16 + 1/2x
3) a. x = number of coins
b. 1/2x - 6
4) 17 + x = 78
Subtract 17 from each side.
x = 61
5) x - 33 = 78
Add 33 to each side.
x = 111
6) x * 84 = 327.6
Divide each side by 84
x = 3.9
7) 1333/8.6 = 155
The speed was 155mph.
8) 2475/110 = 22.5
The trip took 22 and a half hours. (Or "The trip took 22.5 hours."
2z +7 = -5
2z = -5 -7
2z = -12
z= -12 /2
z= -6
