Answer:
C.
The slope means that for every three rides, Brittany uses about 14 tickets.
Step-by-step explanation:
The given line of best-fit is
y = -4.64x + 47.6
Y-intercept is the point where x is zero. For the given equation y-intercept will be 47.6 or 48 rounded to nearest dollar. In other words, y-intercept is also a point where the line cross the y-axis.
From the given graph we can see that the y-axis shows the number of tickets purchased. The point where the line cross y-axis is about 48.
This tells us that Brittany had 48 tickets when she did not take any ride.
In this case, the slope of the line tells us that how many tickets were used for one ride, as x represents the number of rides. For one ride 4.64 tickets were, for 2 rides 2 x 4.64 = 9.28 tickets were used, for 3 rides 13.92 or around 14 tickets were used.
Now if we look at the given options we can easily say the option C is the correct answer.
Option A is not correct as it gives the opposite information than the actual one. Option B is also wrong, as x-intercept will tell us after how many rides the tickets will expire. Option D is wrong as y-intercept gives the number of tickets not the amount of money.
Answer:
5) x = -1
6) x = 2
Step-by-step explanation:
5) 5 + 2x + 6 = x + 10
2x + 11 = x + 10
2x + 1 = x
1 = -x
-1 = x
6) (9x + 7) + (-3x + 20) = 39
6x + 27 = 39
6x = 12
x = 2
Answer:
Step-by-step explanation:
(8 - 0)/(0 + 8)= 8/8= 1
y - 0 = x + 8
y = x + 8
Answer:
Like terms means that the numbers have the same variable after them or they don't have a variable at all. It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.
For example, x + 3x = 1x +3x. Then I add the numbers in the front and I get 4x.
If it had been 4x + 7x + 3, my answer would have been 11x +3. That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.
