Find the slope of (1,8) and (3,12) ?

Mathematics
1 answer:
Marta_Voda [28]3 years ago
3 0

Answer:

The slope is 2.

Step-by-step explanation:

Slope formula is rise/run. So in other words, it is y2-y1/x2-x1. In this case it would be 12-8/3-1. That equals 4/2. You need to simplify that by dividing both 4 and 2 by 2. So, that gives you 2/1. Whenever you have a number over 1 that is the same as saying just the numerator. So the slope would be 2.

Find the perimeter and area of the figure below.
hichkok12 [17]

Answer:

perimeter = 40

area = 46(unit)^2

Step-by-step explanation:

Perimeter - all sides added together

  1. Find unknown sides (8-3 = 5, 12-2 = 10)
  2. Add all sides together (8+2+5+10+3+12 = 40)

Area - Length multiplied by width

  1. Divide shape into two rectangles (#1 is 2x5 and #2 is 3x12)
  2. Find individual area (rectangle #1: 2*5 = 10 / rectangle #2: 3*12 = 36)
  3. Add areas together (10+36 = 46)
  4. Finish with unit squared (46___^2)

Solve the system of equations by substitution:<br> y= x - 2<br> x + y = 12
gizmo_the_mogwai [7]

Answer:

(7,5)

Step-by-step explanation:

A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Substitution can be used by substituting the value of one variable into the equation.

Because y=x-2, we can substitute x-2 into y in x+y=12.

x+(x-2)=12

x+x-2=12

2x-2=12

2x-2+2=12+2

2x=14

x=7

We now substitute x=7 into y=x-2.

y=(7)-2

y=5
