Answer:

A) y=1/5x

Step-by-step explanation:

Coz, the way you identify a perpendicular line is by looking for its negative reciprocal. The neagtive reciprocal of 5= 1/5

Now, to check the ans we can multiply the negative reciprocal by "m"

(m in y=mx+c or y=mx+b)

in this case the "m" is stated as 5, so all we need to do is  1/5*5 if the ans is 1 then your ans is right....and over here it is

So thats how you identify & check perpendicular lines!

The scenario represented by the linear function y = x + 2 is given by:

Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.

A linear function is modeled by:

y = mx + b

In which:

For this problem, we have that:

Thus the function is given by:

y = x + 2.

Which means that the initial amount is of $2, and increases by $1 for each unit of time, hence the correct option is:

Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.

Answer: Length = 10cm

Width = 6cm

Step-by-step explanation:

First and foremost, we should note that

1 meter = 100 cm.

Therefore,

Length = 5m = 500 cm

Breadth = 3m = 300 cm.

Since Elena wants to make a scale drawing of 1 to 50, then

Length = 500 cm / 50 = 10 cm

Breadth = 300 cm / 50 = 6 cm.

Therefore, the length of the scale drawing will be 10 cm and the width of the scale drawing will be 6cm.

Answer:

Use the two ordered pairs to find the slope, m.

Then substitute one set of ordered pairs and m into y = mx + b to solve for b

Step-by-step explanation:

If we are given two ordered pairs of a function and we need to write an equation that represents the linear function, first, what we need to do is to use the two ordered pair to find the slope, m, using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex].

After getting the slope (m), find the value of the y-intercept (b), by substituting the value of one of the ordered pairs and the slope value (m) into y = mx + b.

Once the value of m and b is known, plug in the value of m and b into y = mx + b to derive the equation of the linear function.

Use the 2 ordered pairs to find the slope, m .

Then substitute m and one set of ordered pairs into y = mx + b to solve for b.

If given the 2 ordered pairs for a function, the ordered pairs can be first used to find the slope of the function.

For example

(x₁, y₁)(x₂, y₂)

m = slope = y₂ - y₁ / x₂ - x₁

The slope(m) is then substituted in the slope intercept form equation.

y = mx + b

where

m = slope

b = y-intercept

And one set of the ordered pairs is also substituted in the equation to get the value of the y-intercept(b).

Answer:

The answer is -6x + 6

Step-by-step explanation:

For us to have an infinite number of solutions, then, what we have on the right hand side will be exactly what we have on the left hand side

Since we have -6x + 6 on the left hand side

To have infinite number of solutions, what we have on the right hand side will be the same

Thus, we have -6x + 6 on the second side

Step-by-step explanation: Three tickets total.

2 tickets cost 13$    =26

1 ticket 17 = 43 total

Hope this helped! God Bless!!

The total cost of the tickets for William’s family with 1 adult and 2 children is $43.

William's age = 11 years

Price for an adult = $17

Price for a child = $13

The total number of tickets to be bought will be 3 i.e. William, His Granddad, and William's younger brother i.e. 1 adult ticket and 2 children tickets.

Total price = price of 1 adult ticket + price for 2 children's ticket

Total price =17+2*13

Total price =17+26

Total price =$43

Therefore, the total cost of the tickets for William’s family is $43.

Answer:

There are 15 Black tokens.

Step-by-step explanation:

If the ratio is 8:5 we divide 24 by 8 to get 3. We then do 5 x 3 for the black tokens and get 15.

The number of black tokens in the bag are 15.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

In the bag, there are 24 green tokens in the bag.

And, The ratio of green tokens to black tokens is 8 to 5.

Now,

There are 24 green tokens in the bag.

And, The ratio of green tokens to black tokens is 8 to 5.

So, Number of green tokens = 8x

And,  Number of black tokens = 5x

Hence, We can formulate;

⇒ 8x = 24

⇒ x = 3

Thus, Number of black tokens = 5x

                                               = 5 × 3

                                               = 15

Therefore, The number of black tokens in the bag are 15.

182.58842

Step-by-step explanation:

Given that:

Sample size (n) = 171

Population standard deviation σ = 11

Sample standard deviation s = 11.4

males is more than 11 bpm. For a random sample of 171 adult males, the pulse rates have a standard deviation of 11.4 bpm find the value of the statistic

The test statistic :

X² = ((n - 1) / σ²) * s²

X² = ((171 - 1) / 11²) * 11.4²

X² = ((170) / 121) * 129.96

X² = 1.4049586 * 129.96

X² = 182.58842
