Answer:

y - 4 = -2(x - 5)

Step-by-step explanation:

point slope form is  y-y1 = m(x-x1)

the original equation is given in slope intercept form y = mx + b

Parallel lines have equal slopes so from the given equation  y = -2x-3

the slope m = -2.

Use the given point (5,4) as (x1, y1).

y - 4 = -2(x - 5)

Answer:

[tex]\displaystyle y - 4 = -2(x - 5)[/tex]

Step-by-step explanation:

Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so −2 remains as is as you proceed with plugging the information into the Point-Slope Formula:

[tex]\displaystyle [5, 4] \\ \\ \boxed{y - 4 = -2(x - 5)}[/tex]

Answer: I think its 39

Step-by-step explanation: I did the math

Jan's starting number was 10.

A number is an arithmetic value used for representing the quantity and used in making calculations.

Given that Jan doubled her starting number, added 5, subtract 7, divided by 3, then squared the result.

Let her original number be x

Therefore, {(2x +5 - 7)/3}² = 36

{(2x -2)/3}² = 36

(2x -2)/3 = 6

2x - 2 = 18

2x = 20

x = 10

Hence, Jan's starting number was 10.

Answer:

y= -2

Step-by-step explanation:

y2-y1      6-y =  8

x2-x1       2-4= -2

To solve for y : Your answer has to be 8 then you divide 8/-2 = -4

6-y=8

subtract 6 from both sides   = -y =2

multiply each side by(-1)

to remove the - from Y         (-1)y =(-1)2

                                                   y =-2

Answer:

he makes $112.50

Step-by-step explanation:

first you have to find out how much he makes before tax is taken out. all you do is multiply 12.50 by 30, which gives you $375.00. then, you can either put in the calculator 30%375 or 0.3×375(both are the same thing) and you should get $112.50

Answer:

denote the number of hits that sanchez had with since washington had 18 more hits than sanchez we can say that washington had + 18 hits.

since the total number of hits is 308 we can write

+ ( + 18) = 308.

This is an equation for finding .

2 + 18 = 308

2 = 290

= 145.

so sanchez had 145 hits.

to find the number of hits by washington add 18:

+ 18 = 145 + 18 = 163.

Answer: sanchez had 145 hits and washington had 163 hits.

Answer:

Step-by-step explanation:

The number is represented as x.

81 is added to a number is

81 + x

39 less than three times the number

3x - 39

So

81 + x = 3x - 39

Solve for x.

81 + x = 3x - 39 Add 39 to each side so 39 cancels on the right.

81 + x + 39 = 3x - 39 + 39

81 + x + 39 = 3x

81 + 39 + x = 3x

120 + x = 3x Subtract x from each side.

120 + x - x = 3x - x

120 = 3x - x

120 = 2x    Divide each side by 2

120/2 = 2x/2

120/2 = x

60 = x

Using the exponential distribution, it is found that there is a 0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.

The exponential probability distribution, with mean m, is described by the following equation:

[tex]f(x) = \mu e^{-\mu x}[/tex]

In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.

The probability of finding a value higher than x is:

[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]

In this problem, the mean is of two minutes, hence the decay parameter is given by:

[tex]\mu = \frac{1}{2} = 0.5[/tex]

The probability that it takes more than 3 minutes for the next call to occur is given by:

[tex]P(X > 3) = e^{-0.5 \times 3} = 0.2231[/tex]

0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.

Answer:

Step-by-step explanation

There are many ways to prove this identity. But, I will use the simplest one. If you have a right triangle, the length of the horizontal side is x, the length of the vertical side is y, and the hypotenuse is r. So, the relation between x and r can be written in cosine form:

[tex]\cos\theta=\frac{x}{r}[/tex]

The relation between y and r can be written in sine form:

[tex]\sin\theta=\frac{y}{r}[/tex]

Pythagoras told you that for the right triangle [tex]x^{2}+y^{2}=r^{2}[/tex] should be satisfied. Substitute x and y from the cosine and sine form:

[tex](r\cos\theta)^{2}+(r\sin\theta)^{2}=r^{2}[/tex]

[tex]r^{2}\cos^{2}\theta+r^{2}\sin^{2}\theta =r^{2}[/tex]

the square of r will cancel out, and you can get your identity:

[tex]\cos^{2}\theta+\sin^{2}\theta=1[/tex]

exactly 4

There are 12 adults.

4 like oatmeal cookies the best.

P(exactly 4) = 4/12 = 1/3 = 0.3333...

B)

At least 4

4 5 6 7 8 9 10 11 12

So there are 9 choices (4 .. 12) of those who could like oatmeal cookies the best.

P(9) = 9/12 = 0.75

C)

1 2 3

There are at most 3 people who could like oatmeal cookies the best.

P(<4) = 3/12 = 0.25

Less than 4 who would choose oatmeal cookies = 1/4
