What system of linear equations is shown in the graph? Enter your answers in the box.

Answers

Answer:

The equation of the line with a bold line:

slope = ( 0 - ( -1 ) ) / ( ( 2 - 0 ) )= 1/2

c = -1

Therefore, y <= ( 1 / 2 ) x - 1

The equation of the line with the dotted line:

slope = ( 1 - ( - 2 ) ) / ( 0 - 1) = - 3

c = 1

Therefore, y < - 3x + 1

What are the vertex and x intercepts of the graph of the function below
y=(x-4)(x + 2)

Answers

Answer:

x - intercepts: (4,0) and (-2,0)

vertex: (1/2 ,  - 17/2)

Step-by-step explanation:

Part A

To find the x-intercepts you have to set y=0

(x-4) (x+2) = 0

Separate the parenthesis. Solve for  x

x-4 = 0

x= 4

x+2 = 0

x= -2

x - intercepts: (4,0) and (-2,0)

-------------------------------------------------

Part B

vertex formula for the x: coordinate : -b/2a

Expand the function.

y = 2x^2-2x-8

a = 2

b = -2

c= -8

-b/2a = -(-2)/2(2) = 1/2

vertex x- coordinate: 1/2

Substitute 1/2 back into every "x" in the function to find the "Y" for the vertex.

y = 2(1/2)^2 -2(1/2) -8

y = -17/2

vertex: (1/2 ,  - 17/2)

how many distinct 9-digit numbers can you make from four "1", three "2", and two "3"?

Answers

Answer:

2520

Step-by-step explanation:

If a nine digit number contains exactly 4 one's, 3 two's and 2 three's

We can choose the positions of the 1's in P(9/4) ways.  

We can choose the positions of the 2's from the five remaining positions in P(5/3) ways

We can choose the positions of the 3's from the two remaining positions in P(2/2) ways

In this problem order doesnt matter..

= (9!/5!×4!) × (5!/3!×2!) × (2!/2!×0!)

= 2520

Step-by-step explanation:

The way we solve this is we simply rearrange the equation using algebra.

Step 1) For the first inequality, subtract 1/2 from both sides. This gets x by itself and turns the RHS into -3 1/2.

Step 2) For the second, add 3 to both sides. Once again, x is by itself, and the RHS is equal to 1.

B)

D)

Answers

Answer:

The next term in the sequence is:

     0.00221184

Step-by-step explanation:

We are given that:

A cell-phone company has noticed that the probability of a customer experiencing a dropped call decreases as the customer approaches a cell-site base station.

A company representative approached a cell site at a constant speed and calculated the probability of a dropped call at regular intervals, and the probabilities formed the recursive sequence:

             0.6, 0.4, 0.24, 0.096, 0.02304.

as we can see third term is product of first two terms

fourth term is product of third and second term

fifth term is the product of fourth and third term

so,  the next term in the sequence which is the sixth term will be the product of fifth and fourth term=  0.02304×0.096

                                                  =  0.00221184

calculate the shaded area​

Answers

Answer:

640[tex]cm^{2}[/tex]

(I hope that I am right)

Step-by-step explanation:

The bigger shape :1. First, look at the triangle as a whole -

Area of a triange : [tex]\frac{Base x Height}{2}[/tex]

30 x 48 = 1440[tex]cm^{2}[/tex]

1440 ÷ 2 = 720[tex]cm^{2}[/tex]

2. Now let's look at the small triangle -

20 x 16 = 320[tex]cm^{2}[/tex]

320 ÷ 2 = 160[tex]cm^{2}[/tex]

The area of the bigger shape -720 - 160 = 560[tex]cm^{2}[/tex]

The smaller shape :1. Let's look at the shape as a rectangle first -

Area of a rectangle = Base x Height

20 x 16 = 320[tex]cm^{2}[/tex]

2. Now let's do the little triangle -

20 - 30 = 10

10 x 16 = 160[tex]cm^{2}[/tex]

160 ÷ 2 = 80[tex]cm^{2}[/tex]

The area of the smaller shape -80[tex]cm^{2}[/tex]The Area Of The Shaded Area :560 + 80 = 640[tex]cm^{2}[/tex]

Before it started to rain, Bobby cut 1 8 of the grass in his yard and Danny cut 1 5 of the grass in the yard. Both boys were disappointed because they were not able to cut the entire yard. Which statement is TRUE?
A) Together the boys didn't even cut half the yard.
B) The boys were able to cut more than half the yard.
C) The boys cut almost three-fourths of the yard.
D) Together the boys cut almost the entire yard.

Answers

Answer:

Option A is correct

Step-by-step explanation:

Bobby = 1/8

Danny = 1/5

Let's add up both fractions:

1/8 + 1/5 =

1*5/8*5 + 1*8/5*8 =                   (multiplying both the numerator and                              

5/40 + 8/40 = 13/40                 denominator by the opposite denominator)

Together, they both cut 13/40 of the entire lawn.

Let's check each option:

A) Together the boys didn't even cut half the yard.

True, half of the yard is 20/40, and 13/40 < 20/40

B) The boys were able to cut more than half the yard.

False, half of the yard is 20/40, and 13/40 is not greater than 20/40

C) The boys cut almost three-fourths of the yard.

False, three-fourths of the yard is 30/40, and 13/40 is not close.

D) Together the boys cut almost the entire yard.

False, the entire yard is 40/40 and 13/40 is not close.

140/2 = 70    (the other 2 angles are equvilent angles)

Brainly plz :)

Answer:

answer below

Step-by-step explanation:

every triangle has angle that, added together, equal 180 degrees.

if the given angle is 40 and the red lines tell you the sides are equal in length (both lines have only one red line so they are the same.), calculate the angles. (hint they are both the same amount of degrees.)

My process:

180-40=140

?+?=140

70+70=140

solution= 140 degrees
