Answer:
This question answer is attached in the attachment,
Step-by-step explanation:
10! If you use the trapezoid area formula and plug in the known values, just solve for h(height)
We can observe that the function describing the graph is linear and so the equation is of linear nature:

Numbers m and n have special names. m is called the slope, n is called y-intercept.
From the graph one can tell that the line intercepts y-axis at y = -1 that means n = -1. What about the slope you say?
The slope can be calculated using two points' coordinates that lie on the line:

Now our line has an equation,

Answer:
or 
Step-by-step explanation:

The opposite of
is 

Convert decimal number −0.75 to fraction
.
Reduce the fraction
to lowest terms by extracting and canceling out 25.

Least common multiple of 4 and 5 is 20. Convert
and
to fractions with denominator 20.

Since
and
have the same denominator, add them by adding their numerators.

Add -15 and 8 to get -7

Convert decimal number 0.4 to fraction
. Reduce the fraction
to lowest terms by extracting and canceling out 2.

Least common multiple of 20 and 5 is 20. Convert
and
to fractions with denominator 20.

Since
and
have the same denominator, add them by adding their numerators.

Add -7 and 8 to get 1.

Least common multiple of 20 and 4 is 20. Convert
and
to fractions with denominator 20.

Since
and
have the same denominator, subtract them by subtracting their numerators.

Subtract 15 from 1 to get -14.

Reduce the fraction
to lowest terms by extracting and canceling out 2.

Answer:
the answer you have chosen is right.
Step-by-step explanation:
A rational number can be written as a simplified fraction, and or is a recurring or finite decimal. That is the only number that can be properly written according to the rules I just stated.
