Find the x and y intercept

Please help it's due in 5 minutes

Answers

Answer:

x-intercept = 3

y-intercept = - 6

Step-by-step explanation:

The intersection of the line with the x-axis is known as the x-intercept and it's calculated by making y = 0.

Also, the intersection of the line with the y-axis is known as the y-intercept and it's calculated by making x = 0.  

Given the following data;

Equation of straight line is [tex]y = 2x - 6[/tex]

To find the intersection;

When y = 0, the equation crosses the x-axis.

y = 0;

Substituting into the equation, we have;

0 = 2x - 6

2x = 6

x = 6/2 = 3

x = 3

(x, y) = (3, 0) on the x-axis.

When x = 0, the equation crosses the y-axis.

x = 0;

Substituting into the equation, we have;

y = 2(0) - 6

y = 0 - 6

y = -6.

(x, y) = (0, -6) on the y-axis.

Therefore, the coordinates of the intersection of the graph is (3, 0) and (0, -6).

If the pattern shown continues how many black keys appear on a keyboard with 35 white keys ?

Answers

Answer:

25 black keys

Step-by-step explanation:

Let the number of requires black keys = 'x'

White key : Black keys = 7 : 5

7 : 5  :: 35 : x

Product of extremes = product of means

             7 *x = 35 * 5

                  x = [tex]\frac{35*5}{7}[/tex]

                 x = 5 *5

What are the x-intercepts of this quadratic function? g(x) = - 2(x - 4) * (x + 1)

A. (- 4, 0) and (- 1, 0)
B. (4, 0) and (- 1, 0)
C. (- 4, 0) and (1, 0)
D. (4, 0) and (1, 0)

Answers

I believe it’s C, but please correct me if I’m wrong!

Hi,

The correct answer is B.

The equation is g(x) = -2(x − 4)(x + 1).

In this equation (x - 4) and (x + 1) are the x-intercepts. In this form (x - 4) and (x + 1) are zeros.

Therefore the x-intercepts are (4,0) and (-1,0).

Assume that adults have IQ scores that are normally distributed with a mean of μ= 105 and a standard deviation Ï =20 . Find the probability that a randomly selected adult has an IQ between 85 and 125 .

Answers

Answer:

0.68268

Step-by-step explanation:

We solve using z score

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

For x = 85

z = 85 - 105/20

z = -1

Probability value from Z-Table:

P(x = 85) = 0.15866

For x = 125

z = 125 - 105/20

z = 1

Probabilty value from Z-Table:

P(x = 125) = 0.84134

The probability that a randomly selected adult has an IQ between 85 and 125 is calculated as:

P(x = 125) - P(x = 85)

= 0.84134 - 0.15866

= 0.68268

Answer:

Approximately 107 when rounded to the nearest whole number

see below for more accurate answer

Step-by-step explanation:

First, we pull out our formula.

C is circumference, D is diameter.

[tex]C=2\pi r\\D=2r\\C=\pi D[/tex]

We now insert 34 for D.

[tex]C=34\pi \\[/tex]

Pi is 3.141592653589..., so our answer is approximately 106.814150222. You can round this to your desire.
