Answer:
40=10% im rightthe total is 400
Step-by-step explanation:
You want to solve this set of linear equations by the elimination method.
Let x=price of bag of flour and y=price of bag of sugar
Multiply the first equation by -3.
-3(7x+5y=584)
Multiply the second equation by 5.
5(5x+3y=384)
Solve by elimination.
X=42
Substitute value of x into one of the original equations.
Y=58
Answer:
The graph of
is also attached below, which indicates that there is a change of only one unit on the y-axis for every two units of x-values.
Step-by-step explanation:
When there is a change in x values, it is basically a horizontal change. horizontal change between two values is also called the run.
And the vertically change between two values is also called the rise.
The slope is basically the ratio of the vertical (rise) and horizontal (run) changes between two points on a line.
For example, consider the equation
![y\:=\:\frac{1}{2}x](https://tex.z-dn.net/?f=y%5C%3A%3D%5C%3A%5Cfrac%7B1%7D%7B2%7Dx)
![\mathrm{Slope\:of\:}\frac{1}{2}x:\quad m=\frac{1}{2}](https://tex.z-dn.net/?f=%5Cmathrm%7BSlope%5C%3Aof%5C%3A%7D%5Cfrac%7B1%7D%7B2%7Dx%3A%5Cquad%20m%3D%5Cfrac%7B1%7D%7B2%7D)
Here fore every two units of x-values, one units are moved on the y-axis.
In other words, there is a change of only one unit on the y-axis for every two units of x-values.
The graph of
is also attached below which is showing this.
Answer: n= -1/2
Step-by-step explanation:
H= -1
Distribute:
-(4+h)= -4 - h
-4 - h= 3h
-4 +h = 3h + h
-4= 4h
-1 = h
