The area of the polynomial is 35 square unit.
Step-by-step explanation:
It is given that area of the polygon WXYZ with its vertices at W(–3, –2), X(–3, 5), Y(2, 5), and Z(2, –2)
From the below graph it is noticed that the given polynomial is a rectangle with length 5 and width 7
The distance formula
Using the above formula we get,

Which is the correct equation for a line that has a slope of 2 and passes through the point (-1, -5). Use the graph below or graph paper if needed.
PLEASE HELP ASAP
A.y = 2x - 5
B.y = 2x + 5
C.y = 2x - 3
D.y = 2x + 3
9514 1404 393
Answer:
C. y = 2x - 3
Step-by-step explanation:
The y-intercept (b) can be found from ...
y = mx + b
y - mx = b . . . . . subtract mx
Here, you are given (x, y) = (-1, -5) and slope m = 2.
b = -5 -2(-1) = -5+2 = -3
The correct equation is ...
y = 2x -3 . . . . . matches choice C
_____
On the graph, you can plot point (-1, -5) left of the y-axis 1 unit and down from the x-axis 5 units. The slope of 2 tells you the line will rise 2 units from there to a y-value of -3 when it runs 1 unit to the right to an x-value of 0. That point (0, -3) is the y-intercept, showing you that choice C is correct.
Evaluate the following expression: 8x - 6 - 7y + 3 use x=3 and y=6
Answer:
-27
Step-by-step explanation:
8x - 6 - 7y + 3
X = 3 Y = 6
8(3) - 6 - 7(6) + 3
8 x 3 = 24
7 x 6 = 42
24 - 6 - (42 + 3)
(24 - 6) - 45
18 - 45 = -27
A line segment has endpoints F(2, 2) and G(8, 2) Find the coordinates of its midpoint M
Answer:
(5,2)
Step-by-step explanation:
The midpoint of a line segment is calculated by finding the average of the x values and the average of the y values of the endpoints.
[tex]midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )[/tex] when the points given are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug points F(2,2) and G(8,2) into the equation
[tex]midpoint=(\frac{2+8}{2},\frac{2+2}{2} )\\midpoint=(\frac{10}{2},\frac{4}{2} )\\midpoint=(5,2)[/tex]
Therefore, the midpoint of the line segment with endpoints F and G is (5,2).

Answer:
So the scale factor would be the length of the new rectangle divided by the length of the corresponding side for the original rectangle. So the scale factor is 1/2. Note: If you're going from a bigger shape to a smaller one, you know that the scale factor must be less than 1.

Please Help. Given trapezoid ABCD, Prove ΔBEC ~ ΔDEA
Answer:
AAA (or AA)
Step-by-step explanation:
Prove ΔBEC ~ ΔDEA
(using three angles is unnecessary because you can just use Angle Angle to prove similarity)
First, m∠BCE = m∠EAD because of alternate interior angles.
Then, m∠ADE = m∠CBE because of alternate interior angles.
m∠BEC = m∠AED because of vertical angles
Thus, ΔBEC ~ ΔDEA because of Angle Angle Angle [AAA] (or AA if you only chose to use 2 angles)

Find the radius of the button.
A circular button with a diameter of 28 millimeters.
The radius of the button will be 14 millimetres.
What is the radius of the circle?The radius of the circler is defined as the distance from the centre of the circle to the outermost surface of the circle. The diameter of the circle is the distance between the two points on the surface of a circle passing through the centre of the circle.
Given that the diameter of the circle is 28 millimetres. the radius of the circle is calculated as,
Radius = Diameter / 2
Radius = 24 / 2
Radius = 12 millimetres
Therefore, the radius of the button will be 14 millimetres.

What is the solution to the system of equations2x + 3y = 40andy=x + 10?
A
x = 2; y = 12
B
x = 4; y = 14
C x = 12; y = 2
D x = 14; y = 4
Answer:
A is the correct answer
Step-by-step explanation:
If you plug y=x+10 in for the Y variable you just have to solve by multiplying.
1.) It should look like this:
2x + 3(x +10) = 40
2.) You will distribute the three which will make the equation look like this:
2x + 3x + 30 = 40
3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.
Hope that helps

what are the two angles called
Answer:
The angles are supplementary.

Which table represents a linear function?
How do you solve 13 + 3 - 8x + 6 = 1 - 5x I dont get it
Answer:
x = 7
Step-by-step explanation:
How to solve your question
Your question is 13 + 3 − 8x + 6 = 1 − 5x
13 +3 - 8x + 6 = 1 - 5x
13 + 3 − 8x + 6 = 1 − 5x
Solve
Add the numbers
13 + 3 − 8x + 6 = 1 − 5x
22 − 8x = 1 − 5x
Rearrange terms
22 − 8x = 1 − 5x
−8x + 22 = 1 − 5x
Subtract 22 from both sides of the equation
−8x + 22 −22 = −5x + 1 − 22
Simplify
Subtract the numbers
−8x = -5x + 1 -22
-8x = -5x -21
Add 5x to both sides of the equation
-8x + 5x = -5x -21 + 5x
Simplify
Combine like terms
-3x = -21
Divide both sides of the equation by the same term
(-3x)/3 = (-21)/3
Simplify
Cancel terms that are in both the numerator and denominator
x = (-21)/(-3)
Divide the numbers
x = 7
Answer: x=7
