y=5x+20
If you need to you can graph this in Desmos.
y is cost, 5 is price per dog, x is the number of dogs 5 and x times each other. y is total cost.
I hope this helps.
A meter m is 100 cm.
So m^2 = 100^2 cm^2
Then cm^2 = (m^2)/100^2 =m^2/10000
294cm^2 = 294/10000 m^2 or 0.00294 m^2
The first values are the x axis, wich are sideways but the second values are y axis wich are up and down so since you havent given much context they are 10 -10 and 0
We can use elimination for these set of systems.
First, we need to set up our variables.
Belts=b
Hats=h
Now, the situation is 6 belts and 8 hats for $140. The situation after is 9 belts and 6 hats for $132.
Let’s set up our system of equations.
6b+8h=140
9b+6h=132
We need to eliminate a variable. Since b has coefficients of 6 and 9, we can easily eliminate b by multiplying the top equation by 3 and the bottom by -2.
18b+24h=420
-18b-12h=-264
Now let’s add.
12h=156
Let’s divide to get h by itself.
156/12=13=h
So a hat costs $13. We need to put in 13 for one of the equations so we can find the cost of a belt.
9b+6(13)=132
9b+78=132
We need b by itself.
9b=54
54/9=6
Belts are $6
We can also use the first equation to check our answers.
6(6)+8(13)
36+104
140.
So, the price of a belt is $6 while the price of a hat is $13.
