Answer:
f(x)=
1. 48x when x < or = 3,
2. 45x when 4 < or = x < or = 8
3. 42x when 9 < or = x < or = 19
4. 38x when x > 19
Step-by-step explanation:
3 boxes or less = Cost of tiles = $48
4 - 8 boxes ; cost = $45
9 - 19 boxes ; cost = $42
> 19 boxes ; cost = $38
Y=2x-3 has a steeper line because the bigger the slope, the more it goes up on the y-axis for every one spot on the x-axis.
The first one goes up 2 spaces for every one it goes over, and the second one goes up one space for every 5 it goes over
Answer:
Number of students tickets sold= 184
Number of adults tickets sold= 192
Step-by-step explanation:
I assume we need to calculate the number of student and adult tickets sold.
<u>First, we establish the system of equations:</u>
x= number of students tickets sold
y= number of adults tickets sold
4*x + 7*y= 2,080
x + y= 376
<u>Now, we isolate x in one formula and substitute it in the other:</u>
x= 376 - y
4*(376 - y) + 7y = 2,080
1,504 - 4y + 7y = 2,080
3y = 576
y= 192
x= 376 - 192
x= 184
Number of students tickets sold= 184
Number of adults tickets sold= 192
Answer:
see below
Step-by-step explanation:
It's just long division. Shown is the way I learned. In recent times, other techniques have been taught. At each stage, the divisor is multiplied by the quotient digit and the result subtracted to get the new dividend.
The result is a repeating decimal with a 6-digit repeat. It is the same as 1/63, which is the result of reducing the fraction 57/3591.
