A(b) is a function

True or false

Answer:

Step-by-step explanation:

7). (x + 3)(x + 7)

  = x(x + 7) + 3(x + 7)

  = x² + 7x + 3x + 21

  = x² + 10x + 21

8). (4x + 2)(x - 2)

  = 4x(x - 2) + 2(x - 2)

  = 4x² - 8x + 2x - 4

  = 4x² - 6x - 4

9). (3x + 2)(2x + 5)

  = 3x(2x + 5) + 2(2x + 5)

  = 6x² + 15x + 4x + 10

  = 6x² + 19x + 10

10). (x² - 6)(x - 4)

  = x²(x - 4) - 6(x - 4)

  = x³ - 4x² - 6x + 24

11). (x² + 9)(x - 3)

  = x²(x - 3) + 9(x - 3)

  = x³ - 3x² + 9x - 27

12). (4x²- 4)(2x + 1)

  = 4x²(2x + 1) - 4(2x + 1)

  = 8x³ + 4x² - 8x - 4

Answer:

x.......y

-8...-2

-1....1

0....0

1....-1

8...2

Answer:

-2

-1

0

1

2

Step-by-step explanation:

in order to find the y values you need to plug in the x values in the table into the function

the cube root of -8 is -2 (since this is a cube root instead of a square root we can have negative values in it because when we cube negative values we get negative values i.e. -2³=-8 ; -3³=-27)

the cube root of -1 is -1

the cube root of 0 is 0

the cube root of 1 is 1

the cube root of 8 is 2

Step-by-step explanation:

Step-by-step explanation:

Reflected over the line y=x is (4,1)

Reflected over the line y=-x is (-4,-1)

Rotated through 90 clockwise about the origin is (4,-1)

Rotated through 90 counterclockwise about the origin is(-4,1)

4) Equivalent multiply by 2

5) Equivalent multiply by 2

Answer: 54 square inches and 18 square inches

Explanation:

The formula for the area of a trapezoid is the sum of the top and bottom bases divided by 2, multiplied by the height.

In the first picture the bases are 6 and 12, and the height is 6, so the formula would look like this:

[tex]\frac{6+12}{2} *6[/tex]

=[tex]\frac{18}{2} *6[/tex]

=[tex]9*6[/tex]

=54

54 [tex]in.^{2}[/tex] is the answer to the first problem.

Following the same method, we can do the next problem the same way:

[tex]\frac{4+8}{2} *3[/tex]

=[tex]\frac{12}{2} *3[/tex]

=[tex]6*3[/tex]

=18

18 [tex]in.^{2}[/tex] is the answer to the second problem.

Answer:

10

Step-by-step explanation:

take 6-5=1

6+5=11

These are the parameters of a triangle. If the third side length is equal to 11 then that is impossible.

1<x<11

So the largest value for x would be 10

Step-by-step explanation:

1.

Yes , the data franchise owner is collecting, will be helpful in order to counter the criticism from the critic. As he has a record for every delivery they are making on daily basis.

2.

The scenario is that for every fifth customer , the owner cross the four lines he makes. Thus a pack of five and easy to remember. As the data on regular week days is less, As can do the same for the third customer. Crossing the 2 lines for 3rd customer.

3.

With this provision of crossing the third customer, the owner can have a better check on the late delivery. As it will bring in his notice earlier as compared to fifth crossing.

4.

With the data as provided in the table, we can come to the conclusion that on weekends , i.e. both on time delivery and late deliveries are high in numbers. It must be because of high demand on that days. So owner must make some provision like hiring some more delivery boys for weekend in order to reduce the late deliveries.

Answer:

If im not mistaken it should be answer 3. Because you would have to divide amongst groups.

Answer:

[tex]\frac{1}{6}[/tex]×[tex]\frac{1}{6}[/tex]×[tex]\frac{1}{6}[/tex][tex]=\frac{1}{72}[/tex]

[tex]\frac{1}{2}[/tex]×[tex]\frac{1}{2}[/tex]×[tex]\frac{1}{2} =\frac{2}{8}[/tex]

[tex]\frac{4}{6}[/tex]×[tex]\frac{4}{6}[/tex]×[tex]\frac{4}{6} =[/tex][tex]\frac{8}{27}[/tex]

[tex]\frac{1}{6}[/tex]×[tex]\frac{1}{6}[/tex]×[tex]\frac{1}{6}[/tex][tex]=\frac{1}{72}[/tex]

Answer:

1 in 3 chance

Step-by-step explanation:

Multiples of 3: 3, 6, 9, 12

This means there are 4 multiples.

4/12 or 4 ÷ 12 = 1/3

So there is a 1 in 3 chance (33.333%) to get a multiple of 3

Answer:

  B.  P = 70 in; A = 300 in²

Step-by-step explanation:

The perimeter is the sum of the side lengths. Opposite sides are the same length, so the perimeter is ...

  P = 20 in + 15 in + 20 in + 15 in = 2(20 in +15 in) = 2(35 in)

  P = 70 in.

Only answer choice B has the correct value. (Its area figure is also correct.)

Answer:

I don't know what those answer choices are but the answer should be: [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

4-2 = 2

3 - (-2) = 5

Put the y values over the x

[tex]\frac{2}{5}[/tex]

Answer:

3a(1+3b)

Step-by-step explanation:

First step is to find the greatest common factor between these two terms, which is 3a. Next you'll need to divide the two terms by that factor, which would give you what would be in the parenthesis, placed the factor in front to signify the multiplication of those terms and voila, you got the fully factored form.

Answer:

the 3rd one
