THIS ONE IS KINDA EASY, BUT SOMEONE GIVE ME THE COORDINATES!!
1 answer:
Answer:
Line in slope-intercept form: y = 4/3 x + 4
y-intercept: 4
Slope: 4/3
Coordinates: (-3,0) and (0,4)
Step-by-step explanation:
In case you want to check the coordinates, just use this formula⤵⤵⤵ (Sorry if it's a bit small btw).
Plug it in: ⤵⤵⤵
4 - 0 = 4
0 - (-3) = 0 + 3 = 3
Slope = 4/3
Since the coordinates equal our slope when we plug it in, that's how we know they are correct.
Hope this helps :)

Replcaing equation (3) into equation (2) we got:
And solving for Y we got:
And solving for X from equation (3) we got:
So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
Step-by-step explanation:
For this problem we can work with the concentration of water and orange juice.
Let X the amount for the orange juice with 25% content and Y the amount for the orange juice with 5% of content
Using the concentration of orange juice we have:
(1)
And for the water we have:
(2)
If we solve for X from equation (1) we got:
(3)
Replcaing equation (3) into equation (2) we got:
And solving for Y we got:
And solving for X from equation (3) we got:
So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
