15x+25y=1875
Let
y=95-x
15x+25 (95-x)=1875
Solve for x
15x+2375-25x=1875
15x-25x=1875-2375
-10x=-500
X=500/10
X=50 the number of $15 items
Y=95-50=45 the number of $25 items
Answer:
yes it is
Step-by-step explanation:
Both linear and proportional because as x increases y decreases at the same rate
A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC.

To find the length of a line given two points, we are going to use the distance formula, which is defined below:
( and are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:
- Substitute values into formula
- Combine like terms and then simplify to 0
- Compute
- Compute
The length of DC is 3.
Answer:
I believe x = 4 and z = 97
Step-by-step explanation:
Just equate the two equations to each other and solve for x. For z, just solve one of the equations and substitute x, whatever the answer is (97), is z.
