Answer:

b. -2

Step-by-step explanation:

2x+y=12

add -2x to both sides

y = -2x + 12

this is in slope intercept form y = mx + b

m meaning the slope

in this case the slope is -2

the answer will be b. -2

Answer:

b. -2

Step-by-step explanation:

Note the slope-intercept form: y = mx + b

Note that:

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

First, isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 2x from both sides of the equation:

2x (-2x) + y = (-2x) + 12

y = -2x + 12

Remember, m is the variable for the term that stands for the slope (directly next to the x variable). In this case, your answer will be -2

b. -2 is your answer.

Finding the Area of a Trapezoid in the Coordinate Plane
Oksanka [162]

The area of the trapezoid is 118 squre units

<h3>Area of a trapezoid</h3>

The formula for calculating the area of a trapezoid is expressed as:

  • A = 0.5(a+b)h
  • a  = AD = √20
  • b = BC = √80
  • height = h = √40

Substitute into the formula

A = 0.5(√1600)*√40

A = 0.5 * 40 * √40

A = 20√40

A = 118 squre units

Hence the area of the trapezoid is 118 squre units

Please show your work. Find XY
Sidana [21]
XY = 17. 

Because YW is a perpendicular bisector, we can say that TW and WZ are both equal to 3. It tells us that XZ is 12, so that means that XW must be 12+3 which equals 15.

It also tells us that YW is 8. So we can use the Pythagorean Theorem to find the hypotenuse of Triangle XWY. Thus, 15^{2}  +  8^{2} =  XY^{2}

To solve this equation, square and add both of the terms on the right like this:
289 =  XY^{2}

And then take the square root of both sides. Your final answer should be: 
XY = 17.
