X^2y^8/x^7y^6 if x= -2 and y= 4

damaskus [11]

Answer:

- $\frac{1}{2}$

Step-by-step explanation:

Given

$\frac{x^2y^8}{x^7y^6}$

= $\frac{y^{(8-6)} }{x^{(7-2)} }$

= $\frac{y^2}{x^5}$ , substitute values

= $\frac{4^2}{(-2)^{5} }$

= $\frac{16}{-32}$

= - $\frac{1}{2}$

Write an equation for the line passing through the given pair of points. give the final answer in standard form (-4,-2) and (3,-

Andrew [12]

Answer:

y = -2/7x - 22/7

General Formulas and Concepts:

Pre-Algebra

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 (-4, -2)

Point (3, -4)

Step 2: Find slope m

Substitute: $m=\frac{-4+2}{3+4}$
Add: $m=\frac{-2}{7}$

Step 3: Find y-intercept b

Define: y = -2/7x + b
Substitute: -4 = -2/7(3) + b
Multiply: -4 = -6/7 + b
Isolate b: -22/7 = b
Rewrite: b = -22/7

Step 4: Write linear equation

y = -2/7x - 22/7

Three less than a 6 times a number is 39. find the number

Vanyuwa [196]

Using the problem, create an equation to find the number (x).
Three less than (so x minus 3) 6 times a number (6 times x) equals 39.

6x-3=39, solve for x.
x = 7
