Answer:
a. x+y=10, 2x+3y=24
b.this systems of equations have a unique solution since there is only one value for x and one value for y where each equation is present in. There is no same slope or y-intercept
c. 4 magnet gift boxes
Step-by-step explanation:
Answer:
Step-by-step explanation:
We are given the table representing the cost for the number of letters to be printed on shirts.
As, we know that slope is given by
.
So, taking any two points ( x,y ) from the table say ( 15,7 ) and ( 20,8.25 ), we find the slope.
i.e. ![m=\frac{8.25-7}{20-15}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B8.25-7%7D%7B20-15%7D)
i.e. ![m=\frac{1.25}{5}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1.25%7D%7B5%7D)
i.e. ![m=\frac{1}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1%7D%7B4%7D)
i.e. ![m=0.25](https://tex.z-dn.net/?f=m%3D0.25)
So, the slope is 0.25.
Now, we substitute the value of the slope and the point ( 15,7 ) into the equation y = mx + b.
i.e. 7 = 0.25 × 15 + b
i.e. b = 7 - 0.25 × 15
i.e. b = 7 - 3.75
i.e. b = 3.25
So, the y-intercept is 3.25
Hence, the linear equation is given by y = 0.25x + 3.25.
We know that the company charges a flat fee and also charges amount per letter.
Since, y = 0.25x + 3.25 is the total cost charged for the letters.
This gives us that, the slope 0.25 represents the charge per letter and the y-intercept 3.25 represents the flat fee charged.
Answer:
Infinitely many solutions
Step-by-step explanation:
You can change x for any number. You don't have to give me extra points
I see you put a b c but what are the options of them?
Answer:
nobody gonna answer this for 5 points. you have to put 1 question for each 5 points
