5y-14=2y-2 solve for y and show work plz
Answer:
y=4
Step-by-step explanation:
Let's solve your equation step-by-step.
5y−14=2y−2
Step 1: Subtract 2y from both sides.
5y−14−2y=2y−2−2y
3y−14=−2
Step 2: Add 14 to both sides.
3y−14+14=−2+14
3y=12
Step 3: Divide both sides by 3.
3y/3=12/3
y=4
Answer:
5y + -14 = 2y + -2
-14 + 5y = 2y + -2
-14 + 5y = -2 + 2y
-14 + 5y = -2 + 2y
-14 + 5y + -2y = -2 + 2y + -2y
5y + -2y = 3y
-14 + 3y = -2 + 2y + -2y
2y + -2y = 0
-14 + 3y = -2 + 0
-14 + 3y = -2
-14 + 14 + 3y = -2 + 14
-14 + 14 = 0
0 + 3y = -2 + 14
3y = -2 + 14
-2 + 14 = 12
3y = 12
y = 4

The pentagon ABCDE is graphed on a coordinate plane with vertices A(0, 0), B(3, 5), C(3, 8), D(8, 5), and E(8, 0). What is the pentagon's area?
Answer:
The answer is- 40
Step-by-step explanation:
( :
The area of the pentagon represented here is 40 units².
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given that the coordinates of the vertices of the pentagon given are A(0, 0), B(3, 5), C(3, 8), D(8, 5), and E(8, 0).
We have to find the area.
This pentagon can be divided in to triangle CBD and trapezium ABDE.
Find the area of each to find the total area of the pentagon.
Area of ΔCBD = [tex]\frac{1}{2}[/tex] × BD × CB
Using the distance formula,
BD = [tex]\sqrt{(8-3)^2+(5-5)^2}[/tex] = 5
CB = [tex]\sqrt{(3-3)^2+(5-8)^2}[/tex] = 3
Area of ΔCBD = [tex]\frac{1}{2}[/tex] × 5 × 3 = 7.5
Area of trapezium ABDE = [tex]\frac{1}{2}[/tex] × (AE + BD) × DE
Using the distance formula,
AE = 8, BD = 5 and DE = 5
Area of trapezium ABDE = [tex]\frac{1}{2}[/tex] × (8 + 5)5 = 32.5
Total area of the pentagon = 7.5 + 32.5 = 40 units²
Hence the total area is 40 units².

Answer:
The slope is -5
y intercept is -2
Step-by-step explanation:
Solve the equation for y
5x+y =-2
Subtract 5x from each side
5x+y -5x = -5x-2
y = -5x-2
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -5 and the y intercept is -2
Answer:
Slope -5
y intercept 2
Step-by-step explanation:
5x+y=-2 in the form y =Mx+ c is,.
y=-5x+-2
y=-5x-2
Where m is the slope which is -5
And c is the y intercept i.e 2
what is the volume of the figure below
Answer:
665 ft^3
Step-by-step explanation:
The formula to find the volume of pyramids is 1/3 x length x width x height. One way to solve this is by multiplying the length, width and height, and then dividing it by 3.
14 x 9.5 x 15 = 1995
1995 / 3 = 665
So the volume is 665 cubic feet

The local business will donate $5.00 for every 10 tickets sold. Let x represent tickets sold, and y represent dollars donated. Student A claims that the equation is y = 2x. Student B claims that the equation is y = 1
2
x. Explain who is correct.
Answer:
If we let x be the number of ticket sold and y be the amount in dollars donated then, the equation would be,
x = 2y
We can check our answer by substituting the given,
10 = 2(5)
10 = 10
The equation can also be written as,
y = (1/2)x
Student B is correct.
Answer:
Sample Response/Explanation: The point that represents what the local business will donate is (10, 5). After testing the point in both equations, you can see that student B wrote the correct equation; 5 = 12(10).
Step-by-step explanation:
If you fold a number line so that a vertical crease goes through 0, the points you label would match up. Explain why this happens.
It would happen because 5 is 5 4 is 4 3 is 3 2 is 2 1 is 1 and 0 is only one number 0.
If we fold a number line so that a vertical crease goes through 0, the points will match up for the same because of the same distance on both sides from zero.
What is a number line?A number line is a straight line representing numbers on it either vertically or horizontally.
If we fold a number line so that a vertical crease goes through 0, the points will match up for the same. this is due to the reason the points on a number line from zero are at the same distance on both sides so, the numbers will superimpose on each other when folded vertical through 0.
Since the distance of 1 and -1 is the same as zero so 1 would match -1.
Similarly for -2 and 2, -3 and 3, etc.

The formula for Area of a Circle is: π·r²
R = Radius
π = pi, or 3.14
As long as you know the formula, this is easy!
In class, you may have already been told that the radius is half of the diameter.
1. Half of 3 ft is 1.5 ft.
2. Plug 1.5 in for r, in your calculator
