what is the equation for the graph shown below ??​

Answer:

A

Step-by-step explanation:

-x + 2y = 8

5x + 2y = -4

+ x. -2y. -8

6x = -12

÷6. ÷6

x = -2

5(-2) + 2y = -4

-10 + 2y = -4

+10. +10

2y = 6

÷2. ÷2

y = 3

Answer:

3/4

Step-by-step explanation:

In the above equation the y-intercept is -1 and the slope of the equation is 3/4

Answer:

The answer is C or 3/4.

Step-by-step explanation:

This equation is in point-slope form or Y= mx+b. The variable m represents slope. So, just look for the number that stands in place of m. Hope this helps! Please mark Brainliest! :)

Answer:

x=20 and y=128.Option 2

Step-by-step explanation:

Since,the angles are vertically opposite,they are equal(property)

Therefore,

(3x-8)=(2x+12)

3x-8=2x+12

3x-2x=12+8

x=20,

Now,

Since,the angles are formed in a straight line,their sum is equal to 180(property)

Therefore,

y+(2x+12)=180

y+2×20=180-12

y=168-40

y=128

Therefore,x=20 and y=128

option 2 would be your answer because it explains the missing part where y is.

Answer:

24 cm²

Step-by-step explanation:

The area (A) is calculated as

A = [tex]\frac{1}{2}[/tex] product of the diagonals, that is

A = 0.5 × 6 × 8 = 24 cm²

Answer:

Option A,$320.98  is correct

Step-by-step explanation:

The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.

last balance as shown by the statement was $152.58

new charges were $213.40

payment made by Elijah was  $45

new balance=$152.58+$213.40-$45=$320.98

The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.

Answer:

Other answer is incorrect. Elijah's new balance would be $322.59

Answer:

11.3

Step-by-step explanation:

i used the theorem of Pythagoras

Answer:

11.3

Step-by-step explanation:

In a right angled triangle:  the square of the hypotenuse is equal to

the sum of the squares of the other two sides.

[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)

64 + 64 = [tex]x^{2}[/tex]

[tex]x^{2}[/tex] = 128

=> x = [tex]\sqrt{128}[/tex] = 11.3137085 = 11.3

Option A is correct.

Braylee's music is 3 times louder than Jessica's.

Step-by-step explanation:

Full Complete Questions

The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as

L = 10log (I/I₀), where lo = 10⁻¹² W/m²

and is the least intense sound a human ear can hear.

Jessica is listening to soft music at a sound intensity level of 10⁻⁹ W/m² on her computer while she does her homework.

Braylee is completing her homework while listening to very loud music at a sound intensity level of 10⁻³ W/m² on her headphones. How many times louder is Braylee’s music than Jessica’s?

times louder

3 times louder

30 times louder

90 times louder

Solution

The loudness of a sound intensity is given as

L = 10 log (I/I₀)

For Jessica

I = 10⁻⁹ W/m²

I₀ = 10⁻¹² W/m²

L = 10 log (10⁻⁹/10⁻¹²)

L = 10 log (10³)

L = 10 × 3 = 30 dB

For Braylee

I = 10⁻³ W/m²

I₀ = 10⁻¹² W/m²

L = 10 log (10⁻³/10⁻¹²)

L = 10 log (10⁹)

L = 10 × 9 = 90 dB

How many times louder is Braylee's music than Jessica's?

The factor by which Braylee's music is louder than Jessica's = (90/30) = 3

Braylee's music is 3 times louder than Jessica's.

The number of groups of 5 boys that we can have from 7 boys is 7C5 = 21

The number of groups of 5 boys that we can have from 12 students is

12C5 = 792

then the probability = 21/792 = 0.026515151515

by the way you can calculate 12C5 and 7C5 using a calculator.

Answer:

For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula

Step-by-step explanation:

The great pyramid of Cheops is a square based pyramid therefore we have;

V + F = E + 2

Where:

V = Vertices

F = Faces

E = Edges

Hence, we have for a square pyramid;

V = 5 vertices (One at the peak, and four  at the base edges)

F = 5 faces (The four lateral or side faces and the base)

E = 8 edges ( The four lateral edges and the four base edges)

Hence;

5 + 5 = 8 + 2 which proves Euler-Descartes formula.

Step-by-step explanation:

Answer: One large pizza with a radius of 12 inches

Step-by-step explanation:

Hi, to answer this question we have to calculate the area of each option.

Area of a circle: π r^2  

A = π r^2 = π 6^2 = 113.1 in2

Since there are 2 small pizzas we have to multiply the area by 2:

113.2 x 2 = 226.2 in2

A = π r^2 = π 12^2 = 452.38 in2

Since 452.38 in2 > 113.1 in2

Option 2 (one large pizza) will give her more square inches of pizza

Answer:

event A and B are independent because  P(A and B)  = P(A) x P(B) = 0.15

Step-by-step explanation:

When two events are independent, the probability of both occurring is the product of their separate probabilities, as expressed below;

P(A and B)  = P(A) x P(B)

Given;

P(A) =  0.25

P(B) = 0.60

P(A and B) = 0.15

Now, let's check if  P(A and B) will be equal to P(A) x P(B)

P(A) x P(B) =  0.25 x 0.60 = 0.15

P(A and B)  = P(A) x P(B), thus event A and B are independent.

Answer:

B.) 7

Step-by-step explanation:

7 x 4 = 28

28 + 12 = 40

:)

Using multiplication, the original number is 7.

Multiplication is "the process multiplying that the integer is multiplied by number of time".

According to the question,

A number is multiplied by 4. The results is added to 12. The final number is 40. In order to find original number.

4x + 12 = 40

        4x = 40 -12

        4x = 28

          x = 28/4

          x = 7.  

Hence, using multiplication, the original number is 7.
