The first one: -7(x) + 4(y) = 24
The second one: 4(x) - 4(y) = 0
4y - 7x = 24 which is reduced to a negative
(-4y + 4x = 0 )
4(x) = 4(y)
-7(y ) + 4(y) = 24
- 3(y) = 24
3(y) = - 24
y-intercept: - 8
x-intercept: -8
The X & Y intercept is: -8, -8
The answer is :
YES: These points represent a function because none of the vertical lines I drew passed through more than one point.
Answer: 12 friends.
Step-by-step explanation:
the data we have is:
Mei Su had 80 coins.
She gave the coins to her friends, in such a way that every friend got a different number of coins, then we have that:
The maximum number of friends that could have coins is when:
friend 1 got 1 coin
friend 2 got 2 coins
friend 3 got 3 coins
friend N got N coins
in such a way that:
(1 + 2 + 3 + ... + N) ≥ 79
I use 79 because "she gave most of the coins", not all.
We want to find the maximum possible N.
Then let's calculate:
1 + 2 + 3 + 4 + 5 = 15
15 + 6 + 7 + 8 + 9 + 10 = 55
now we are close, lets add by one number:
55 + 11 = 66
66 + 12 = 78
now, we can not add more because we will have a number larger than 80.
Then we have N = 12
This means that the maximum number of friends is 12.
The equation of the line in this graph is y = 3/2x + 3.
Explanation:
In slope intercept form equations, the initial value is where everything begins. In this equation, that would be at the point (0,3). From there, because it is going up toward the right side, there is a positive slope. The formula for slope is rise over run, so to get our slope, we have to go up 3 units and over 2 units.
Answer:

This is calculated as the number of women divided by the population of the class
i.e.
So, we have:
