Answer:
x=10, y=4
Step-by-step explanation:
3x-3y=18
(-)3x-(-)8y=-(-)2 -3x+8y=2 add to first equation to eliminate x
5y=20
y=4
substitute y with 4
3x-3(4)=18
3x=30
x=10
x=10,y=4
Answer:
Company C!
Step-by-step explanation:
In order to see which company has the best buy we have to see the amount each company sells for one stuffed mascot. In order to do this we have to divide .
Company A:
Company A sells 16 lions for $44.32 this is the same as 1 stuffed lion for $2.77.
Company B:
Company B sells 18 lions for $50.22 this is the same as 1 stuffed lion for $2.79.
Company C:
Company C sells 12 lions for $32.88 this is the same as 1 stuffed lion for $2.74
Thus as you can see the company with the best buy is company C.
Answer: y = 3x + 1
<u>Step-by-step explanation:</u>
The equation is in Slope-Intercept format: y = mx + b where
- m is the slope <em>(difference in y's over difference in x's)</em>
- b is the y-intercept <em>(value of y when x = 0)</em>
![m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\\\text{Let }(x_1,y_1)=(0,1)\quad \text{and}\quad \text{let }(x_2, y_2)=(1,4)\quad then\\\\m=\dfrac{4-1}{1-0}=\dfrac{3}{1}=3](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5C%5C%5C%5C%5C%5Ctext%7BLet%20%7D%28x_1%2Cy_1%29%3D%280%2C1%29%5Cquad%20%5Ctext%7Band%7D%5Cquad%20%5Ctext%7Blet%20%7D%28x_2%2C%20y_2%29%3D%281%2C4%29%5Cquad%20then%5C%5C%5C%5Cm%3D%5Cdfrac%7B4-1%7D%7B1-0%7D%3D%5Cdfrac%7B3%7D%7B1%7D%3D3)
b = 1 <em>refer to the table that shows y = 1 when x = 0</em>
Now input m = 3 and b = 1 into the Slope-Intercept formula:
y = 3x + 1
