Answer:
No, it is not
Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
1420-1065 = 355 dollars. Lets find out how many percent 355 dollars are of the original prise. We divide them 355/1420= 0,25, we then say 0,25 * 100 = 25%
Answer:
x=4,y=−2
Step-by-step explanation:
1 Solve for x in -2y+x=8
x=8+2y
2 Substitute x=8+2y into 3y+2x=2
7y+16=2
3 Solve for y in 7y+16=2
y=-2
4 Substitute y=-2 into x=8+2y
x=4
5 Therefore,
x=4
y=−2
Answer:
B. y = 3x + 1
Step-by-step explanation:
We can look at the table like a bunch of values, where (x) is what is inserted into the equation, and (y) is what comes out.
Now, simply insert the (x) values into each equation and see if they work out or not.
y = (1/3)(-1) + 1 does not equal -2, meaning this equation is defunct.
y = 3(-1) + 1 = -2; y = 3(0) + 1 = 1. This must be the equation as it works for the (x) values given. You can try the other equations, but a simple look at them is all you need to prove them false.
The answer is - 40. Observe.
y/-4 + 5 = 15
y = -40
-40/-4 = 10
10 + 5 = 15
Thus, y= -40
