Look at the graph: What is the slope?

Mathematics
1 answer:
Arisa [49]3 years ago
5 0

Answer:

The slope is 2/3

Step-by-step explanation:

The line crosses through the blue grid lines leaving gaps on each. Find two points which cross at an intersection such as (0,30) and (30,50). Find the slope by substituting these points into the slope formula:

m = \frac{y_2-y_1}{x_2-x_1} = \frac{50-30}{30-0} =\frac{20}{30} =\frac{2}{3}

Answer:

P=23.9\ inches

Step-by-step explanation:

<u>Formula Evaluation</u>

Formulas are expressions where a sequence of letters, numbers or symbols have a determined meaning in given system.

Formulas are usually expressed as mathematical operations that connect one or more variables.

The perimeter of a triangle is the sum of the lengths of its sides. Being a,b, and c their sides, then the perimeter has the formula

P=a+b+c

We are given the values of

a=13\ inches

b=7.2\ inches

c=3.7\ inches

Thus the perimeter is

P=13\ inches+7.2\ inches+3.7\ inches

\boxed{P=23.9\ inches}
