This expression has four terms.
5, 9x, 7, and 2x
A term is a constant number, a variable, or a variable with a coefficient.
Answer:
x=-2
Step-by-step explanation:
Combine like terms:
10- 2x - 7 - 8x = 5
10-(-7)=<u>10+7</u>=17
<u>2x-8x</u>=-6x
17-6x=5
-17 -17
6x=-12
÷6 ÷6
x=-2

In this item, we are to determine the equation that would allow us to express the given. If x is the number of barrels of water and y is weight, the points are:
(10, 98.4) and (20, 181.8)
To determine the equation of the line, we use,
y - y₁ = ((y₂ - y₁)/(x₂ - x₁))(x - x₁)
Substituting,
y - 98.4 = ((181.8 - 98.4)/ (20 - 10))(x - 10)
Simplifying,
y = 8.27x + 88.4
