Answer:

ygfgjuhggffffffthbbvftyyhh hhggtyy hhgf hggff hggff hhgf vgt

Answer:

D

Step-by-step explanation:

The change from x = 0 to x = 1 is -3

The change from x = 1 to x = 2 is -5

The average of -3 and -5 is [tex]\frac{-3-5}{2} = \frac{-8}{2} = -4[/tex]

The answer is D. -4

Answer:

Step-by-step explanation:

8x+2y=16

2y=-8x+16

y=-4x+8

slope is -4

y-intercept is (0,8)

x-intercept is (2,0)

Answer:

slope = -4

y-intercept = (0,8)

x-intercept = (2,0)

Step-by-step explanation:

To find the slope:

8x + 2y = 16. First get the y by itself.

2y = -8x + 16. Then divide by 2

y = -4x + 8. So the slope is -4.

y-intercept:

8x+2y=16

8(0)+2y=16

2y=16

y=8

y-int: (0,8)

x-intercept:

8x+2y=16

8x+2(0)=16

8x=16

x=2

x-int: (2,0)

Answer: The probability is 0.536

Step-by-step explanation:

We have 3 blue marbles, and 5 red marbles (a total of 3 + 5  = 8 marbles)

First, we take a marble and it is not replaced.

Then we take another marble.

We want to calculate the probability of getting only one blue marble.

Then we have two cases:

1) First we take a blue marble, and after a red marble

2) First we take a red marble, and after a blue marble.

Let's calculate the probability of these two events:

1) The probability of taking a blue marble at random, is equal to the quotient between the number of blue marbles, and the total number of marbles.

this is: p1 = 3/8.

Now we need to take a red marble. Same procedure as before, but now we already taken a marble from the bag, so the total number of marbles is 7 now, and the number of red marbles is 5. The probability here is:

p2 = 5/7

The joint probability (the probability of both events happening) is equal to the product between the individual probabilities, this is:

P = p1*p2 = (3/8)*(5/7) = 0.268

2) Now we first take a red marble, we can calculate the probabilities in the same way than above.

The probability of taking a red marble at first is:

q1 = 5/8

The probability of taking a blue marble in the second draw is:

q2 = 3/7

The joint probability is:

Q = p1*p2 = (5/8)*(3/7) = 0.268

The total probability of getting only one blue marble will be equal to the addition of both the probabilities we found.

Probability = P + Q = 0.268 + 0.268 = 0.536

Use PEMDAS to find your answer

Answer:

20 degrees

Step-by-step explanation:

You know that the three angles will add up to 180 degrees, so you can make an equation:

3x (angle 1) + 2x + 20 (angle 2) + 5x - 40 (angle 3) = 180

3x + 2x + 20 + 5x - 40 = 180

Then, solve

combine like terms

10x - 20 = 180

add 20 to both sides

10x = 200

divide both sides by 10

x = 20 degrees

Step-by-step explanation:

3x+5x-40+2x+20=180°{sum of triangles}

10x-20=180

10x=180+20

x=200

10

x=20°

The Volume of a Rectangular Prism

Given a rectangular prism of dimension W, L, and H, the volume is calculated as:

V = WLH

Each small cube of the figure has a volume of 1 cube centimeter. We need to calculate the volume of each solid and determine which ones have a volume of 36 cube cm.

A: V = 5*3*4 = 60 cube cm

B: V = 3*3*4 = 36 cube cm

C: V = 3*4*2 = 24 cube cm

D: V = 6*2*3 = 36 cube cm

E: V = 2*4*2 = 16 cube cm

Correct choices: B, D

Answer:

Answer:

(-1, -2) will be the solution.

Step-by-step explanation:

System of equations has been given as,

y = 3x + 1 ---------(1)

Input-output value table for the given line will be,

x       -2        -1          0          1

y      -5        -2         1           4

y = -x - 3 ----------(2)

Input-output value table for the given line will be,

x        -2         -1           0           1

y       -1          -2          -3         -4  

By plotting the given coordinates we can draw the straight lines.

And the point of intersection (common point) of these lines will be the solution of the given system of equations.

Hence, (-1, -2) will be the solution.

Answer:

The total sales of Boutique last week = $1300

Step-by-step explanation:

Given that:

Percent of sales came from leggings = 30%

Worth of leggings sold = $390

Let,

x be the total sales in the week.

30% of x = 390

[tex]\frac{30}{100}x=390[/tex]

0.3x = 390

Dividing both sides by 0.3

[tex]\frac{0.3x}{0.3}=\frac{390}{0.3}\\x=1300[/tex]

Hence,

The total sales of Boutique last week = $1300

The Correct Answer Is H

Step-by-step explanation:

Its Order Corresponds idenically to the graph above.

Answer:

Option B: x = 15 is a solution, but x = 9 is not is the correct answer.

Step-by-step explanation:

Given equation is:

x - 3 = 12

The solutions we have to check are;

x = 9 and x = 15

Putting x = 9 in the given equation;

9 - 3 = 12

6 ≠ 12

Putting x = 15 in the given equation;

15 - 3 = 12

12 = 12

Hence,

Option B: x = 15 is a solution, but x = 9 is not is the correct answer.

Answer:

-20

Step-by-step explanation:

Let the number be Y

If the sum of a number and seven is doubled, the result is six less than the number, The statement is as expressed below

2(Y+7)= Y-6

Find the value of Y

2Y+14=Y-6

Put the like terms together

2Y-Y=-6-14

Y=-20

The number is therefore -20

Verifying

2(-20+7)=-20-6

2(-13)=-26

-26=-26
