Answer:
<h2>x=2</h2><h2>y=4</h2>
Step-by-step explanation:
5x-y=6
2x+y=8
add them up
7x=14
divide by 7 to get x
x=2
fit it into both equation
y=4
36.89 total divided by the 8.6 gallons he bought = 4.2 so the price per gallon would be $4.20
Answer:
B.
Step-by-step explanation:
A goes up by 1
C goes up by 8
D goes up by 5
But B increments by 2x (2 times)
The tax is 4%, do 1.36 divided by 34
To answer the question, simplify the polynomial by adding those that has the same degree of variable,
6 - 3x + (6x³ - 2x³)
6 - 3x + 4x³
Rearrange the polynomial with decreasing exponent or x,
4x³ - 3x + 6
This is a third-degree polynomial.
