substitute for your equation;
h(x) = f(x) - g(x)
h(x) = (3x + 2) - (-2x -4)
h(x) = 3x + 2 + 2x + 4 (minus and minus = addition)
h(x) = 3x + 2x + 2 + 4 (combine like terms)
h(x) = 5x + 6
Hope that helps! :D

Write an equation to describe the relationship between ccc, the number of cranes, and ttt, the total time in minutes.
Answer:
t = 3.5c
Step-by-step explanation:
The correct table is attached in the image below. Since the papers are being folded at a constant rate, there is a linear relationship between c, the number of crane and t, the total time in minutes.
We can find the equation of this linear relation using any two pair of points from the table. Using the first two points: (5, 17.5) and (8, 28)
First we need to find the slope of the line which gives the relation between the two variables.
y coordinates represents the dependent variable which is the time in this case and x coordinates represents the independent variable which is number of cranes in this case. Using the values from the two points we considered:
Thus, the equation of the line will be of the form:
t = mc + b
m is the slope here. Using its values, we get:
t = 3.5c + b
b is known as y-intercept. We need the value of b to complete the equation. Substituting the value of t and c from any pair we can find the value of b.
Using the point (5, 17.5), we get:
17.5 = 3.5(5) + b
b = 0
This means, the equation of the line would be:
t = 3.5c
Answer:
t=3.5c
Step-by-step explanation:
As one inch is equivalent to 2.54 centimeters in 50.8 centimeters there is 20 inch.
A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, One inch is equivalent to 2.54 centimeters.
Therefore, The number of inches in 50.8 cm can be obtained by dividing 50.8 centimeters by 2.54 centimeters.
= 50.8/2.54.
= 20 inch.
