By solving the linear equations we get the final values of x = 4 & y = 4.

What is the linear equation?

A linear equation is an algebraic equation of the form y=mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order  term are included.

We have,

               2x + 7y = -20           ----------(i)

                x - 3y = 16               ----------(ii)

By multiplying equation (ii) with 2 we get,

               2x + 7y = -20 ---------(III)

               2x - 6y = 32 -----------(IV)

taking subtraction of equations (III) and (IV), we get

               y = 4

by putting value of y in equation (ii) we get,

               x = 4

Hence by solving the linear equations we get the values of x = 4 & y = 4.

Roger owns a one-acre piece of land. The length of the land is 484 feet. What is the width of his property?
shepuryov [24]

Answer:

W = 90 ft

Step-by-step explanation:

1 acre = 43,560 ft^2

A (area) = L (length) x W (width),

L = 484

A = 43560

W = A/L

= 43560/484

= 90 ft

Select the equation of the line parallel to the equation y = -2x - 7 that passes through the point (3, 1).
sasho [114]
Y = -2x - 7 
slope = -2 (parallel shares the same slope, -2)

Option A:
y = -2x + 7
slope = -2

At (3, 1)
y = -2(3) + 7 = 1

Answer: Option A
