Which value of b will cause the quadratic equation x2 + bx + 5 = 0 to have two real number solutions? –5 –3 3 4

Answer:

Yes, because it passes the vertical line test

Step-by-step explanation:

A function has one output for each input.  This is called a one to one correspondent.  This is shown by the vertical line test

This graph passes the vertical line test and is therefore a function

Answer:

D

Step-by-step explanation:

The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.

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

Example: The first table is a function because each input value has only 1 output value, but the second table has more that one output value per input.  (View Attached Picture Below)

The input value 4 in Table A has only 1 output value, 20. But in Table B, the input value for 4 has 2 output values, 16 and 17. So Table A is a function, while Table B is not.

Answer:

y=4

Step-by-step explanation:

Anna:

1st month = 18 + [tex]\frac{3}{4}[/tex] = 18[tex]\frac{3}{4}[/tex] inches

2nd month = 18[tex]\frac{3}{4}[/tex] + [tex]\frac{3}{4}[/tex] = 19[tex]\frac{1}{2}[/tex]

3rd month = 19[tex]\frac{1}{2}[/tex] + [tex]\frac{3}{4}[/tex] = 20[tex]\frac{1}{4}[/tex]

4th month = 20[tex]\frac{1}{4}[/tex] + [tex]\frac{3}{4}[/tex] = 21

5th month = 21 + [tex]\frac{3}{4}[/tex] = 21[tex]\frac{3}{4}[/tex]

Grace:

Because Anna is [tex]\frac{9}{4}[/tex] inches shorter than Grace, we can start the count from the third month:

1st month = 20[tex]\frac{1}{4}[/tex]

2nd month = 21

3rd month = 21[tex]\frac{3}{4}[/tex]

4th month = 21[tex]\frac{3}{4}[/tex] + [tex]\frac{3}{4}[/tex] = 22[tex]\frac{1}{2}[/tex]

5th month = 22[tex]\frac{1}{2}[/tex] + [tex]\frac{3}{4}[/tex] = 23

Answer:

The solution is at (-4,-4).

Step-by-step explanation:

(-4x=-60-19y)-1          Multiply by -1

4x = 60 + 19y

-7x = -48 - 19y         Add both equations together

-3x = 12                   Divide both sides by -3

x = -4

Plug this into the first equation to find the value of y

-4(-4) = -60 - 19y        Multiply

16 = -60 - 19y

+60  +60                    Add 60 to both sides

76 = -19y                    Divide both sides by -19

y = -4

Step-by-step explanation:

The distance between (6,-2) and (1,-2) is 5.

Answer:

The distance:

[tex]d = 5[/tex]

Step-by-step explanation:

To find the distance between points [tex](6,-2)[/tex] and [tex](1,-2)[/tex], you need the distance formula:

[tex]d = \sqrt{(x_{2} - x_{2})^{2} + (y_{2} - y_{1})^{2}}[/tex]

-Use the given points [tex](6,-2)[/tex] and [tex](1.-2)[/tex] for the distance formula:

[tex]d = \sqrt{(1 - 6)^{2} + (-2 + 2)^{2}}[/tex]

-Then, solve the formula:

[tex]d = \sqrt{(1 - 6)^{2} + (-2 + 2)^{2}}[/tex]

[tex]d = \sqrt{(-5)^{2} + (0)^{2}}[/tex]

[tex]d = \sqrt{25 + 0^{2}}[/tex]

[tex]d = \sqrt{25 + 0}[/tex]

[tex]d = \sqrt{25}[/tex]

[tex]d = 5[/tex]

So, the distance is [tex]5[/tex].

Answer:

7.19 is the tip

Step-by-step explanation:

Take the amount of the bill and multiply by the tip percentage

47.96 * 15%

Change to decimal form

47.96 * .15

7.194

Round to 2 decimal places

7.19

Answer: $7.19

Step-by-step explanation:

15/100 = 0.15

We only want the tip, not the total cost:

Do 0.15 * $47.96 to get about $7.19

Step-by-step explanation:

Answer:

The answer for x should equal: -1.

Step-by-step explanation:

To find x, we would divide, our final value, by 1 to get x. In other words, you would divide: -1 ÷ 1 to get -1 as our unknown number.

Answer:

Todd's Z-score is - 0.27    

Step-by-step explanation:

Explanation:-

Step(i):-

Given data A test is normally distributed with a mean of 70 and a standard deviation of 10.

Mean of the population 'μ' = 70

Standard deviation of the Population ' σ ' = 10

let 'x' be the random variable in normally distributed

Step(ii):-

Given raw score  'x' = 55

Todd's Z-score

                      [tex]Z = \frac{x-mean}{S.D}[/tex]

                     [tex]Z = \frac{55-70}{55}[/tex]

                     Z = -0.27

Final answer:-

Todd's Z-score is - 0.27                    

Answer:

Step-by-step explanation:

Let

( x1 , y1 ) =( 14 , 22)

( x2 , y2) = ( - 5 , 22)

Now the slope of line is given by

Slope(m)

= ( y2 - y1) / ( x2 - x1)

= ( 22 - 22) / ( -5 - 14 )

= 0/-19

= 0
