Answer:
For y = 1/3x - 4
Step-by-step explanation:
First make and equation. Since you want to find the number of the day where both charge the same total amount, you would make the equation:
let x= the number of days
110+46(x)=70+54(x)
Solve:
110-70+46(x)=70-70+54(x)
40+46(x)=54(x)
40+46(x)-46(x)=54(x)-46(x)
40=8(x)
40/8=8x/8
5=x
Therefore your answer would be 5 days
Answer:
Step-by-step explanation:
x² = 40² + 9²
= 1600 + 81
x² = 1681
x = √1681
x= 41
Step-by-step explanation:
1. when x is 0
y will be
4x+2y=10
4(0)+2y=10
0+2y=10
collect like terms
2y=10-0
2y=10
divide both sides by 2
2y/2=10/2
y=5
so when x =0 y will equal to 5
2. when x is 1
y will be
4x+2y=10
4(1)+2y=10
4+2y=10
collect like terms
2y=10-4
2y=6
divide both sides by two
2y/2=6/2
y=3
so when x is 1, y is 3
3. when x is 2
4x+2y=10
4(2)+2y=10
8+2y=10
(CLT) 2y=10-8
2y =2
y= 1
Answer:
312 mi/hr
Step-by-step explanation:
Distance = 2184 miles
Time taken = 7 hours
Average speed = Distance / time taken
Average speed = 2184 miles / 7 hours
Average speed = 312 miles per hour
Hence, the average speed Traveled by the plane traveling from Knoxville to Los Angeles is 312 miles per hour
