A is 60% of B , B is 30% of C, what percentage of C is A

zaharov [31]

A is 30% more than B. So, A = B + 30% of B = B + 30/100 *B = B + 3/10 *B = 13/10 *B. B is 60% less than C. So, B = C - 60% of C = C - 60/100 *C = C - 3/5 *C = 2/5 *C.

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
