So the answer is 14 ounces
Explanation
Since 16.8 is the original plus 20% we could say 16.8=120%

And since X is the original we could say X=100
So using that info we could put it into a proportion
120/100=16.8/x or
120. 16.8
——=. ———-
100. X
Then we cross multiply and divide
So,
120x=16.8(100)
120x=1680 then divide both sides by 120
X=14

This table models a linear function. x −8 −4 4 8 y −3 0 6 9 Enter the coordinates of the y-intercept in the boxes.

adell [148]

Answer:

y-intercept is 3

Step-by-step explanation:

We are given table

x: -8 -4 4 8

y: -3 0 6 9

We can select any two points

$x_1=-8,y_1=-3$

$x_2=-4,y_2=0$

Firstly, we will find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{0+3}{-4+8}$

$m=\frac{3}{4}\quad$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

we can plug values

$y+3=\frac{3}{4}(x+8)$

now, we can solve for y

$y=\frac{3}{4}x+3$

For finding y-intercept , we can plug x=0

$y=\frac{3}{4}\times 0+3$

$y=0+3$

$y=3$

So,

y-intercept is 3

use the substitution method to solve the system of equations choose the correct ordered pair x-y=2 2x+3y=14

k0ka [10]

Answer:

(8/5 , -2/5)

Step-by-step explanation:

x-y=2

2x+3y=14

-y=-x+2

y=x-2

2x+3(x-2)=14

2x+3x-6=14

5x-6=14

5x=8

x=8/5

y=(8/5)-2

y= -2/5
