➷ perimeter = side 1 + side 2 + side 3

perimeter = 3 + 4 + 5 = 12

area = base x height/ 2

area = (3 x 4) / 2

area = 6

The perimeter is 12 ft and the area is 6 ft

1. I think the underlined number is 2. So It will be hundredths.

2. (8 x 100) + (6 x 10) + (3 x 1) + (1/10) + (4/100) + (1/1000)

Or 800 + 60 + 3 + 0.1 + 0.04 + 0.001

What is the slope of a line with points -5,7 and 1,1

KATRIN_1 [288]

Answer

6/-11

Step-by-step explanation:

use the slope formula m= $\frac{y 2-y 1}{x 2-x 1}$

then sub in numbers m= $\frac{7-1}{-5-1}$

now subtract numerator and the denominator

$7-1= 6$ and

$-5-6=-11$ this now looks like $\frac{6}{-11}$

A line passes through the points (-3, 14) and (-1, 16). What is its equation in slope-intercept form?

timurjin [86]

Answer:

y = 6x + 22

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Point (-3, 14)

Point (-1, 16)

Step 2: Find slope m

Substitute: $m=\frac{16-14}{-1+3}$
Subtract/Add: $m=\frac{12}{2}$
Divide: $m=6$

Step 3: Find y-intercept b

Define: y = 6x + b
Substitute: 16 = 6(-1) + b
Multiply: 16 = -6 + b
Isolate b: 22 = b
Rewrite: b = 22

Step 4: Write linear equation

y = 6x + 22
