Answer:

x=2, y=1

x=-2, y = -1

Step-by-step explanation:

x - 2y = 0

x = 2y

x² - y² = 3

(2y)² - y² = 3

3y² = 3

y² = 1

y = 1 or y = - 1

x = 2 or x = -2

Determine the area of the composite shape.
OLEGan [10]

Answer:

132 ft²

Step-by-step explanation:

The shape is composed of a rectangle and a triangle.

Area of the shape = area of rectangle + area of triangle

Area of rectangle = L*W

L = 12 ft

W = 8 ft

Area of rectangle = 12*8 = 96 ft²

Area of triangle = ½bh

b = 8 ft

h = 21 - 12 = 9 ft

Area of triangle = ½(8*9) = 36 ft²

Area of the shape = 96 + 36 = 132 ft²

What is the solution set for 4x−3=2x+5 , given the replacement set {2, 3, 4, 5} ?
Elden [556K]
We have the equation:

4x - 3 = 2x + 5

Let's to change "-3" to the right side of equation, but changing the sinal

4x = 2x + 5 + 3

4x = 2x + 8

Now, we let's to change "2x" to the left side of equation. But, we also will go to change the sinal

4x - 2x = 8

2x = 8

We pass "2" dividing by the 8

x = 8 ÷ 2

x = 4

Tha answer to this questions is ,

X = 4

I hope this has helped.
