Answer: A. 300 - 70h = 30
Step-by-step explanation:
Rest of the question is:
Which of these following equations represents the hours, h, the bus has travelled.
The driver is going at 70 kilometers per hour meaning that for every hour that passes, 70km has been traveled. Expression to find the distance travelled given hours is:
= 70h
There are 300km between the two cities and 30km are left in the journey. Expression is therefore:
300 - 70h = 30
This shows that when you find the distance travelled so far and deduct it from 300, you will get 30km.
If you multiply $1500 by 0.04 which is 4% you get $60 from the interest and if you multiple $1560X0.04=$62.40 and if you repeat the posses 1 more time you earn $64.90 more from interest so in total it was three blocks of 4% interest was earned.<span />
Answer:
Point form - (3,22)
Equation form - x=3, y=22
Step-by-step explanation: Solve for the first variable in one of the equations, then substitute the result into the next equation.
I hope this helps you out! ☺
Answer:
275 is the amount SPENT per month for rent. Since you are decreasing that amount from your savings, it is represented with a negative sign.
The formula is: y = mx + b where
- m is the rate --> -275 per month
- b is the fixed rate --> 3500 savings
If you think about it logically - You have 3500 and spend $275 per month
1st month: 3500 - 275 = 3225
2nd month: 3225 - 275 = 2950
3rd month: 2950 - 275 = 2675
4th month: 2675 - 275 = 2400
5th month: 2400 - 275 = 2125
6th month: 2125 - 275 = 1850
It is easier to write it as an equation where x is the number of months and y is the balance for that month.
y = -275x + 3500
To check if the point (6, 1850) is on the line, input x = 6 and y = 1850
y = -275x + 3500
1850 = -275(6) + 3500
1850 = -1650 + 3500
1850 = 1850
Since it makes a true statement, (6, 1850) is a point on the line.
