There might be something missing in the given equation. Since C is a function of x, the equation must contain x. For sample purposes, let's just assume the equations are:
C(x) = 0.35x for x≤8000
C(x) = 0.75x for x≥8000
The domain is from 0 to 42000. This is the x-axis as shown in the picture. Sample calculations are shown on the left of the graph. The blue graph is for the function C(x) = 0.35x for x≤8000, while the orange graph is for the functionC(x) = 0.75x for x≥8000.The graph break is located when x = 8000.
Answer:
25
Step-by-step explanation:
look B=C
so,
A+B+C=180 Sum of all <s of Tri
x+5+3x+3x=180
7x=175
x=175÷7
x=25
To figure this out, you would first isolate one of the variables in one of the two equations given.
I will first isloate the second equation's Y by subratcting it on both sides to get it onto the other side, thus not changing any of the values in the equation, just moving it around.
The equation would be: x=0+y or simply x=y
You plug in the x to the first equation with parenthesis around it to get it all into on equation: (y)+3y=-4
Add the two like terms, y and 3y to get 4y=-4
Divide that equation by four on both sides to get y=-1
Plug -1 into the second equation that you had moved around (x=y) to get x=-1
So -1=y and -1=x
28y-16y=12y
hope this helps!
Answer:
e = -2
Step-by-step explanation:
9e - 7 = 7e - 11
Subtract 7e from both side
2e - 7 = -11
Add 7 to both sides
2e = -4
Divide by 2 to isolate e
e = - 2
