Answer:
-3
Step-by-step explanation:
1. Write down the decimal divided by 1
2. Multiply both top and bottom by 10
3. Simplify the fraction.
The equation that matches the given points is g(x) = -1.4x + 7.6
The standard form of a linear equation is expressed as 
- m is the slope of the line
Using the coordinate points (3, 3.4), (4,2)

Substitute m = -1.4 and the coordinate (4, 2) into the formula:

Get the required equation:

Hence the equation that matches the given points is g(x) = -1.4x + 7.6

Answer:
f(x)=-3x+4
(can't see some of your choices)
Step-by-step explanation:
We want x to be independent means we want to write it so when we plug in numbers we can just choose what we want to plug in for x but y's value will depend on our choosing of x.
So we need to solve for y.
9x+3y=12
Subtract 9x on both sides
3y=-9x+12
Divide both sides by 3:
y=-3x+4
Replace y with f(x).
f(x)=-3x+4

Answer: 62.5%</h3>
Explanation:
There are 50+30 = 80 grams of sugar and water mixed together.
The percentage of sugar is 50/80 = 5/8 = 0.625 = 62.5%
