Figure ABCD has vertices A(−3, 2), B(2, 2), C(2, −4), and D(−3, −2). What is the area of Figure ABCD? 5 square units 20 square u
Sladkaya [172]

Answer:

The area of Figure ABCD is 25 square units

Step-by-step explanation:

we have

A(−3, 2), B(2, 2), C(2, −4), and D(−3, −2)

step 1

Plot the figure

using a graphing tool

The figure is a trapezoid

see the attached figure

step 2

Find the area of the trapezoid

The area of the trapezoid is equal to

A=\frac{1}{2}[AD+BC]AB

we have

AD=2-(-2)=4\ units ---> difference in the y-coordinates

BC=2-(-4)=6\ units ---> difference in the y-coordinates

AB=2-(-3)=5\ units ---> difference in the x-coordinates

substitute

A=\frac{1}{2}[4+6]5

A=25\ units^{2}

The equation representa Function A and the graph represents Function B
worty [1.4K]

Answer:

D) Slope of Funcation B = - Slope of Function A

Step-by-step explanation:

The equation for the line is:

y=mx+b

Where m is the slope and b is the y-intercept

In this question, we are only interested in the slope.

For function A, we can see that the equation is f(x) = -2x + 1

Going back to the equation, we can see that -2 is the slope

Now for function B, we need to find the slope by looking at the graph.

To do this, you need to remember that the slope is y/x, or rise over run. (This is saying that every time the y happens, the x also happens. For example, if the slope is 1/2, every time the line goes up 1 unit, it goes to the right 2 units)

So for the function, we can see that when you move to the right 1 unit (run), you also move up 2 units (rise), so the slope would be

2

Comparing the slope of both the functions

Function A is -2

and

Function B is 2

So the answer is D

The concrete company pours 8 sections of sidewalk each of which is 2 5/6 feet long. What is the length of the entire sidewalk th
Simora [160]

Answer: 22 2/3 feet

Step-by-step explanation:

From the question, a concrete company pours 8 sections of sidewalk each of which is 2 5/6 feet long. The length of the entire sidewalk that the concrete company pours will be calculated by multiplying 8 by 2 5/6 feet. This will be:

= 8 × 2 5/6

= 8 × 17/6

= 136/6

= 22 2/3 feet

Use the equation (y= -2x + 3) to create a table of values using x-values of -1,3,5. Remember, the ordered pairs can be verified
Yuliya22 [10]

Answer:

(x,y)

(-1,5)

(3,-3)

(5,-7)

Step-by-step explanation:

y= -2x + 3      

y=-2(-1)+3          y=5

y=-2(3)+3          y=-3

y= -2(5) + 3      y=-7
