Step-by-step explanation:
Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth.
5y2 - 8y = 2
The solution of y are 1.82 and -0.22
The general expression for quadratic equation is given as :
ax² + bx + c = 0
The quadratic formula of the above equation is given as
x = -b ± √b²-4ac / 2a
According to the question we have been the expression as
5y² - 8y = 2
Converting it into general expression we get
5y² - 8y - 2 = 0
Putting the required value in above quadratic formula we get
y = -(-8) ± √(8)² - 4*5*(-2) / 2*5
y = 8 ± √64 + 40 / 10
y = 8 ± √104 / 10
y = (8 ± 10.2)/10
y = 8 + 10.2 / 10 and y = 8-10.2 / 10
y = 18.2 / 10 and y = -2.2/10
y = 1.82 and y = -0.22
Hence the solution of y are 1.82 and -0.22

If JK = x + 8, KL = 10, and JL = 7x, what is JK?
Answer:
10 is the jk because x + 8 is 10
I hope it will help
Answer:
11 units
Step-by-step explanation:
It's clear that,
JL = JK + KL
Given that,
JK ⇒ ( x + 8 )
KL ⇒ 10
JL ⇒ 7x
So, by using these data we can make an expression like this.
JL = JK + KL
7x = x + 8 + 10
Now make x the subject and find the value of x.
7x = x + 8 + 10
7x = x + 18
7x - x = 18
6x = 18
6x/6 = 18/6
x = 3
And now let us find the value of JK.
JK ⇒ x + 8
To, find the value of JK we have to replace with 3.
JK ⇒ x + 8
JK ⇒ 3 + 8
JK ⇒ 11 units

Find three consecutive even integers such that the square of the third is 52 more than the square of the second.
The Three consecutive numbers will be 24.5, 25.5, 26.5
We have to take three consecutive numbers. Let the first number be 'x' and the consecutive two numbers be (x + 1), and (x + 2).
It is given that the square of the third number is greater than the square of the second number by 52. We need to create an equation that represents this situation. So, we get :
=> (x + 2)² = (x + 1)² + 52
=> x² + 4x + 4 = x² + 2x + 1 + 52
=> x = 49/2 => x = 24.5
We get value of x = 24.5. Putting this value of x in consecutive numbers we get the first, second, and third numbers as 24.5, 25.5, and 26.5 respectively.
Hence, we get the three consecutive numbers: 24.5, 25.5, and 26.5

Answer:

Step-by-step explanation:
your welcome
Can someone help me with this?
Answer:
Choice A: 11
Step-by-step explanation:
We have x² - y² = 19
x² - y² = (x + y)(x-y)
So (x + y)(x-y) = 19
Since x and y are integers as per the first statement (x, y ∈ Z), we also have x + y = integer and x-y = integer
Take (x + y)(x - y) = 19
Since 19 is prime its only factors are 1 and 19
So we have two situations which can satisfy the above
Either x + y = 1 and x -y 19 or x + y = 19 and x -y = 1
1. Let's try x + y = 1 and x - y = 19
Adding both equations together gives us 2x = 20 (y-terms cancel)
==> x = 10 ==> 10 + y = 1 or y = -9
So 2x - 9 => 2(10) - (-9) = 20 + 9 = 29
This is not one of the choices so we can go on to the next case
2 Let's take x + y = 19 and x - y = 1
Adding these two equations gives us
2x = 20, x = 10 as before
Use 10 in the equation x + y = 19
==> 10 + y = 19
==> y = 19 - 10 = 9
2x - y ==> 2(10) - 9 ==> 20 - 9 = 11
So answer is choice A: 11

2(4x - 3) - 8 = 4 + 2x
Answer: x=3
Step-by-step explanation:
2(4x - 3) - 8 = 4 + 2x
8x - 6 - 8 = 4 + 2x
8x - (6 + 8) = 4 + 2x
8x - 14 = 4 + 2x
8x - 14 + 14 = 4 + 14 + 2x
8x = 18 + 2x
8x - 2x = 18 + 2x - 2x
6x = 18
6x/6=18/6
x=3
x = 3
first you want to distribute 2 to 4x and -3
8x-6 -8 = 4 +2x
then you subtract the numbers on the left side
8x-6-8
8x-14= 4 +2x
then we want to rearrange the 4 and 2x
8x - 14 = 2x+4
the add 14 to each side and move 2x to both sides
6x=18
then divide

Answer:
Area of two rooms is 357 square feet
Length of the baseboards = 89.5 ft
Step-by-step explanation:
Area and perimeter of rectangular room:Area of the room = length * width
Area of the two rooms = area of bigger room + area of smaller room
= 19 * 15 + 8 * 9
= 285 + 72
= 357 square feet
To find the length of the baseboard, we need to subtract the width of the opening (5 feet) and width of the entry (2 1/2 feet) from the perimeter of the bigger room and subtract the width of the opening (5 feet) from the perimeter of the smaller room.
Bigger room:
length = 19 ft
Width = 15 ft
Width of the entry = 2 1/2 ft = 2.5 ft
Width of the opening between two rooms = 5 ft
Perimeter of bigger room = 2l + 2w - 5 - 2.5
= 2*19 + 2*15 - 7.5
= 38 + 30 - 7.5
= 60.5 ft
Smaller room:
length = 8ft
Width = 9 ft
Width of the opening = 5 ft
Perimeter of the smaller room = 2*8 + 2*9 - 5
= 16 + 18 - 5
= 29 ft
Length of the base board = 60.5 + 29
= 89.5 ft
A light bulb manufacturer did an inventory count

It showed they had 2000 bulbs in the warehouse
Each bulb had been purchased at a delivered
cast of £2 with a average delivery cost of f0:30
per bulb and light bulbs have selling price of
£2.20 what is the value of the inventory.
The value of the inventory will be 4000
Bulbs in the warehouse: 2000 bulbs
Cost of each bulb to the manufacturer: 2
Average delivery cost = 0.30
The selling price of the bulb = 2.20
Value of inventory: The monetary value assigned to the items in inventory at the end of an accounting period is known as inventory valuation. The inventory is valued based on the expenses incurred to get it and prepare it for sale.
The biggest current business assets are inventories. You can assess your cost of goods sold (COGS) and, ultimately, your profitability, thanks to inventory valuation.
The value of the inventory is calculated on the cost price, therefore the value of the inventory will be:
= Cost of each bulb*Number of bulbs
= 2000*2
= 4000
So, the value of the inventory will be 4000

Question: When time equals 0, why is the height of the cannon ball not equal to 0? Describe the domain of this function. Describe the range.
The height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground
When time equals 0, why is the height of the cannonball not equal to 0?From the graph, we have the y-intercept to be
y-intercept = (0, y), where y > 0
This means that the graph starts above the origin
This in other words mean that the initial height of the cannonball is above the ground (e.g. it could be on a building)
Hence, the height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground

Whitney buys two submarine sandwiches for an after-school party. One sandwich is 45 inches long and the other sandwich is 20 inches long. Whitney wants to cut servings of the same length from both sandwiches, without having any sandwich left over. What is the greatest length serving that Whitney can cut?
Answer:
5 inches
Step-by-step explanation:
Whitney wants the greatest length that is an even divisor of both 45 inches and 20 inches.
Greatest common factorThe length Whitney is looking for is called the "greatest common divisor" (GCD) or "greatest common factor" (GCF) of the two numbers 45 and 20. There are a couple of different ways this can be found.
FactoringThe prime factors of the two numbers are ...
45 = 3×3×5
20 = 2×2×5
The only factor common to the two products is 5. It is the greatest common factor.
Whitney can cut lengths of 5 inches.
Euclid's algorithmAnother way to find the GCD is to use Euclid's algorithm. That has you ...
Divide the larger number by the smaller and keep the remainder.If the remainder is not zero, replace the larger number with it and repeat.If the remainder is zero, the smaller number is the GCD.Using this algorithm, we have ...
45/20 = 2 r 5
20/5 = 4 r 0 . . . . . The GCD is 5

Please see the graph attached.
What is compound inequality?A compound inequality has two inequality statements joined either by the "or" or “and.”
We have,
6x+2y<12 or x-6y>6
We can graph each inequality.
And we also need to see the intersection between the inequalities.
Let,
6x + 2y = 12____(1)
x - 6y = 6_______(2)
From (1)
x = (12 - 2y ) / 6 put in (2)
(12 - 2y) / 6 - 6y = 6
2 - 1/3y - 6y = 6
2 - 6 = (1/3)y + 6y
-4 = 19y / 3
y = -12 / 19
y = - 0.63 put in (1)
6x + 2 x (-0.63) = 12
6x = 12 + 1.26
x = 13.26 / 6
