First, let's find the solution.
-2x + 3y = 8
Add 2x to both sides.
3y = 2x + 8
Divide both sides by 3.
y = 2/3x + 8/3
4x + 2/3x + 8/3 = -2
14/3x + 8/3 = -2
Subtract 8/3 from both sides.
14/3x = -14/3
Multiply both sides by 3/14.
x = -1
y = 2/3(-1) + 8/3
y = -2/3 + 8/3
y = 6/3, or 2.
The solution is (-1, 2) which lies in Quadrant II, because its outline is (-, +).
Answer:
- y-intercept: 2000
- rate of change: 500
Step-by-step explanation:
When Timon starts, he is already $2000 in debt. If we represent Timon's debt with positive numbers, the y-intercept will be $2000.
Timon's debt seems to be increasing at the rate of $500 per month. That value is the rate of change.
After m months, Timon's debt d will be ...
d = 500m + 2000
There is 90 deaths per day.
First it tells us 32,400 people died in 2015, which also mean that many people died that year.
We have to find the number of people died each month first.
32,400÷12 because 12 is the total number of months in a year.
2700 people died in a month, not we need to find how many people died each day so we divided it by 30 and we get
90 deaths per day.
The equation which is equivalent to 60% of 25 is x = 0.6 * 25
An equation is used to show the relationship between variables, numbers.
Let x represent the value of 60% of 25. Hence:
x = 60% of 25
x = 0.6 * 25
Hence the equation which is equivalent to 60% of 25 is x = 0.6 * 25
x/25 = 60/100
6/10 = x/25
