Answer:

1. The slope of the line is 7/3

2. y intercept is -3

3. y= 7/3x -3

Step-by-step explanation:

To find the slope of the line you use the equation y2-y1/x2-x1

y2 and y1 are y coordinates of the 2 coordinates on the same line that you want to find the slope of and the same with x2 and x1

The y-intercept is the point where the line crosses the y axis and x= 0

the equation of a line is y= mx+b

m= slope

b= y intercept

Answer:

3,9

Step-by-step explanation:

hint: quadratic function

the form can be x² or x²+b or x²+bx+c

when p(-1)= 2 it means if we take x-axis = -1 the result (y-axis) will be 2. Same thing happen if we take x = 7

the vertex will always in the middle. So the middle of x = -1 and x = 7 is 3

-1, 0, 1, 2, 3, 4, 5, 6, 7

the vertex will occured when x = 3

the only answer with x = 3 is the fourth one (3,9)

Answer:

Not widely used. If you continue to increase an angle it will eventually 'double back' on itself and form a full 360° angle. This is the Full Angle. One could argue that this is the same as a zero-sized angle. But we generally mean the reflex angle and so it is a full circle or 360°. Adjust the angle above and try to create the full angle going around in both directions.

Answer:

108

Step-by-step explanation:

236 + 196 = 432 (total stars)

432 / 4 = 108 rows.

Answer:

108 rows.

Step-by-step explanation:

236 stars + 196 stars = 432 stars in total

So if you're putting 432 stars in 4 rows, you have to divide 432/4, which equals 108 rows with 4 stars in each row.

Step-by-step explanation:

Answer:

P(RR) = 3/7 * 3/7 = 9/49

P(BB) = 4/7 * 4/7 = 16/49

We want to know P(RR) + P(BB)

P(RR) + P(BB) = 9/49 + 16/49 = 25/49

Answer:

Green ball. $11

Step-by-step explanation:

Let's see.

15 balls. 7 are red. 6 are green. rest are yellow. That means there are 2 yellow balls.

Since there are more greens than yellows, you have a better chance of getting a green. That means you have a higher chance of getting $11

The total expected value of the game is $2 if you pay $8 to play the following game of chance.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

You pay $8 to play the following game of chance. There is a bag containing 15 balls, 7 are red, 6 are green and the rest are yellow.

Yellow balls = 15 - 7 - 6= 2

Probability of yellow = 2/15

Probability of green = 6/15

Expected value of the game = 6(2/15) + 3(6/15) = $2

Thus, the total expected value of the game is $2 if you pay $8 to play the following game of chance.

Answer:

x+y=15 ; 2x+4y=50

Step-by-step explanation:

Let x be the number of people

Let y be the number of dogs.

Total number of heads = 15

As

1 person has 1 head

1 dog has 1 head

Total no. of heads of people = 1 * x = x

Total number of heads of dogs = 1*y = y

Equation becomes:

x+y=15

Total number of legs = 50

As

1 person has 2 legs

1 dog has 4 legs

Total no. of legs of people = 2 * x = 2x

Total number of legs of dogs = 4*y = 4y

Equation becomes:

2x+4y=50

Answer:

19.5 inches a.k.a. 1 foot and 7.5 inches

Step-by-step explanation:

1) To make it easier, convert Sean's dad's height into solely inches.

6 feet and 6 inches = 6(12) + 6 = 72 + 6 = 78 inches

2) Find out what is one-fourth of Sean's dad's height.

In order to do that, you must simply multiply 78 by [tex]\frac{1}{4}[/tex].

[tex]78(\frac{1}{4} ) = 19.5[/tex]

3) Convert back to feet and inches (if necessary)...

19.5 inches = 12 + 7.5 = 1 foot and 7.5 inches

Answer:

radius is 8; center is at (13, 0).

Step-by-step explanation:

Compare the given  (x - 13) ^ 2 + y ^ 2 = 64 to:

                                  (x - h)^2 + (y - k)^2 = r^2.  (h, k) represents the center

                                                                             and r the radius.

Since 64 = r^2, r = the radius = 8 units  = r

We also see that h = 13 and k = 0.  

Thus, the center of the given circle is (13, 0).

Step-by-step explanation:

3x-2.5x+0.5=4.5

We move all terms to the left:

3x-2.5x+0.5-(4.5)=0

We add all the numbers together, and all the variables

0.5x-4=0

We move all terms containing x to the left, all other terms to the right

0.5x=4

x=4/0.5

Answer:

10 inches

Step-by-step explanation:

The length of the playground in its actual size is 120 feet.

The scale drawing uses a scale of 1 inch to 12 feet.

This means that 1 inch in the drawing equals 12 feet in actual size.

Therefore, the length of the playground on the scale drawing is:

1 inch = 12 feet

x = 120 feet

Cross-multiply:

120 * 1 = 12 * x

=> x = 120 / 12 = 10 inches

The length of a side of the playground on  the scale drawing is 10 inches.

Answer:

Step-by-step explanation:

This is a binomial probability problem. There are only two outcomes. It is either a chosen person has immunity to a particular disease or he does not. The probability of success in this case, p is the probability that a chosen person has immunity to a particular disease. Thus

p = 0.6

The probability of failure, q is q = 1 - p

Thus, q = 1 - 0.6 = 0.4

Mean = np

Where n represents sample size. Thus,

Mean = 12 × 0.6 = 7.2

Answer:

Domain : [-4,4} or  [tex]-4\leq x\leq 4[/tex]

Zeros of the function: (-2, 0, 2)

Intervals when function is positive: (0,2)

Intervals where function is negative: (-4,0), (2,4)

Step-by-step explanation:

Domain can be defined as the input of all possible values of x in the given interval. We can se from the graph that minimum value of x is -4 while maximum value of x is 4. So

[tex]-4\leq x\leq 4[/tex]

The value of function becomes 0 at three places, when x becomes -2,0 or 2

We can see that the function is negative throughout the interval (-4,0), then it become positive from (0,2), then it becomes negative again from (2,4)

Answer:

Some equations have two solutions because a quadratic expression can be written as the product of two linear factors and each factor can be equated to zero, So there exist two solution.

The answer to the quation is x = -2 or x =10

Step-by-step explanation:

Quadratic equation are equations with a leading degree of two. The solutions to the given quadratic equation is 10 or -2

Quadratic equation are equations with a leading degree of two. Given the equation

(x-4)^2-28=8

The equation has two solution because it has a leading degree of 2.

Given

(x-4)^2-28=8

Add 28 to both sides

(x-4)^2-28 + 8=8 + 8

(x-4)^2= 36

Take square root of both sides

√(x-4)^2= ±√36

x - 4 = ±6
x = 6 + 4 or -6 + 4
x = 10 or -2

Hence the solutions to the given quadratic equation is 10 or -2

Answer:

Any integer x can be represent in form of 3k, 3k+1, or 3k + 2 (k is integer).

Case 1: x = 3k => x^2 - 2 = 9k^2 - 2, which will not be divisible by 3

(notice that 2 is not divisibble by 3, but 9k^2)

Case 2: x = 3k + 1 => x^2 - 2 = 9k^2 + 6k + 1 - 2 = 9k^2 + 6k - 1, which will not be divisible by 3

(notice that 1 is not divisibble by 3, but 9k^2 + 6k)

Case 3: x = 3k + 2 => x^2 - 2 = 9k^2 + 12k + 4 - 2 = 9k^2 + 12k - 2, which will not be divisible by 3

(notice that 2 is not divisibble by 3, but 9k^2 + 12k)

=> x^2 - 2 will never be divisible by 3

Answer:

x=6

Step-by-step explanation:

As MK and ML are tangent to the circle, they are also congruent (MK = ML). Thus we can set the equation:

6x-15 = 2x+9

Now solve for x:

6x-2x = 9+15

4x=24

x=6

Answer:

B.

Step-by-step explanation:

MK and ML are tangents to a circle and " originating from the same point" so

MK=ML

Since MK = 6x-15 and ML = 2x+9

So,

6x-15 = 2x+9

6x-2x = 9+15

4x = 24

Dividing both sides by 4

So, we'll get

x = 6
