THIS ONE IS KINDA EASY, BUT SOMEONE GIVE ME THE COORDINATES!!

Mathematics
1 answer:
Greeley [361]3 years ago
3 0

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).

\frac{y _{2} - y _{1}  }{x _{2} - x _{1}}

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 :)

One canned orange juice is 25% orange juice another is 5% orange juice. How many liters of each should be mixed together in orde
Cerrena [4.2K]

Answer:

X = \frac{1.6 - 0.05Y}{0.25}= 6.4 -0.2 Y  (3)

Replcaing equation (3) into equation (2) we got:

0.75(6.4 -0.2 Y) +0.95 Y = 18.4

And solving for Y we got:

4.8 -0.15 Y +0.95 Y = 18.4

0.8 Y = 13.6

Y = 17

And solving for X from equation (3) we got:

X= 6.4 -0.2*17 = 3

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:

0.25 X + 0.05 Y = 20*0.08  (1)

And for the water we have:

0.75 X + 0.95Y = 20*0.92  (2)

If we solve for X from equation (1) we got:

X = \frac{1.6 - 0.05Y}{0.25}= 6.4 -0.2 Y  (3)

Replcaing equation (3) into equation (2) we got:

0.75(6.4 -0.2 Y) +0.95 Y = 18.4

And solving for Y we got:

4.8 -0.15 Y +0.95 Y = 18.4

0.8 Y = 13.6

Y = 17

And solving for X from equation (3) we got:

X= 6.4 -0.2*17 = 3

So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
