length = x

width = 2x

x(2x) = 1682

2x^2 = 1682

x^2 = 841

x = sqrt(841) = 29

length = 29 meters

width = 29 x 2 = 58 meters

What is x-2y=3 in slope intercept form

Gennadij [26K]

So firstly, subtract x on both sides: $-2y=-x+3$

Next, divide -2 on both sides, and your answer will be y = 1/2x - 3/2 , or the last option.

Which equation shows y=3/4x−52 in standard form? 4x−3y=10 4x−3y=−10 3x−4y=10 3x−4y=−10

snow_tiger [21]

Y = 3/4x - 5/2....subtract 3/4x from both sides
-3/4x + y = -5/2 ....multiply everything by common denominator of 4
-3x + 4y = -10

Answer:

D. y = ±√(25 -x²)

Step-by-step explanation:

Subtract x² and take the square root to solve for y.

x² +y² = 25 . . . . . . . given

y² = 25 -x² . . . . . . . . subtract x²

y = ±√(25 -x²) . . . . . take the square root
