Answers

Answer 1

The slope between (-8,4) and (3,-1) is -5/11 and the slope of 4x - 3y = 13 is 4/3

What is the slope between (-8,4) and (3,-1)?

The points are given as

(-8,4) and (3,-1)

The slope between the points is calculated using

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

So, we have

Slope = (-1 - 4)/(3 + 8)

Evaluate

Slope = -5/11

Hence, the slope between (-8,4) and (3,-1) is -5/11

What is the slope of 4x - 3y = 13?

The equation of the line is given as

4x - 3y = 13

Make 3y the subject of the formula

So, we have

3y = 4x - 13

Make y the subject of the formula

So, we have

y = 4/3x - 13/3

A linear equation is represented as

y= mx + c

Where

Slope = m

By comparison, we have

m = 4/3

Hence, the slope of 4x - 3y = 13 is 4/3

How do you know a graph represents direct variation?

A graph that represents direct variation is a linear graph that passes through the origin

What is true about the slopes of parallel lines?

The slopes of parallel lines are equal

i.e. m1 = m2

What is true about the slopes of perpendicular lines?

The slopes of perpendicular lines are opposite reciprocals

i.e. m1 = -1/m2

What is an equation of a line?

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

We have,

The line is perpendicular to y = 3x - 2 and passes through (3, 4).

The slope of the line and the slope of y = 3x - 2 is:

[tex]m_{1} m_{2}[/tex] = -1

Where [tex]m_{2}[/tex] = 3

[tex]m_{1}[/tex] = -1/3

The equation for the line that passes (3, 4) is given by:

In a bake sale, you recorded the number of muffins sold and the amount of sales in a table as shown.

a. What is a function that relates the sales and the number of muffins?

Answers

The function that relates the sales and the number of muffins is :

S = 2.5 m

What is the sales amount ?

The sales amount can be find by the total sales. That is , if there are n products to sell and selling amount is x rs. then we can easily find the total sales by multiplying them and by this total sales we can easily find the number of items sold per units and vice versa.

In the question given,

amount (A) = $ 250.00

Now take any of two values from table ,

Choose any two points and calculate the slope:

slope = [tex]\frac{50 - 20}{20 - 8}[/tex] =  2.5

thus, y = 2.5x

Hence we can say the function that relates the sales and the number of muffins is :

A laptop comes without any programs installed on it. Each program costs $ 20 and the laptop you want costs $ 319 . What is the greatest number of programs you can buy if you want to spend at most $ 500 for the laptop?

Answers

We can buy 9 programs after buying the laptop if we want to spend $ 500 at most on the laptop.

The cost of the laptop = $ 319

The maximum money we have = $ 500

Money left after purchasing the laptop will be calculated by using subtraction.

Money left = $ 500 - $ 319 = $ 181

Now, cost of each program = $ 20

The number of programs we can buy = $ 181 / $ 20

The number of programs we can buy = 9.05

That means 9 programs.

Therefore, we get that, we can buy 9 programs after buying the laptop if we want to spend $ 500 at most on the laptop.

(f⁰f)(0)

Answers

A composite function exists as a function that depends on another function. The value for  (f⁰f)(0) = - 4/3

What is meant by composition function?

In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.

Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.

Let the two functions be g(x) = 3x + 2 and f(x) = x - 2/3

Now, (f⁰f)(x) = f[f(x)]

f(x) = x - 2/3

(f⁰f)(x) = f( x - 2/3)

simplifying the above equation, we get

(f⁰f)(x) = (x - 2/3) - 2/3  

(f⁰f)(0) = - 2/3 - 2/3

(f⁰f)(0) = - 4/3

Therefore, the value of (f⁰f)(0) = - 4/3.

Ryan and Aqil had 352 stickers altogether. After Ryan lost 25% of his stickers, the ratio of Ryan's stickers to Aqil's stickers was 9:4. How many stickers did Aqil have?​

Answers

Aqil have 88 stickers.

Let Ryan have x stickers initially. Then Aqil will have (352-x) stickers. Ryan lost 25% of his stickers i.e., x-(25% of x)

= x- 25x/100

= x-x/4

= 3x/4

After Ryan lost 25% of his stickers, the ratio of Ryan's stickers to Aqil's stickers was 9:4 i.e.,

3x/4 : (352-x) = 9 : 4

⇒ 3x/4/(352-x) = 9/4

⇒3x/4 x 4 = 9 x (352-x)

⇒3x = 3168-9x

⇒3x+9x = 3168

⇒12x = 3168

⇒x = 3168/12

⇒x = 264

∴ Ryan have 264 stickers of the total 352 stickers and Aqil will have (352-x) i.e., 88 stickers.

Hence, Aqil have 88 stickers out of the 352 stickers.

A business owner made a survey where he ask his customers150 what do they like the most between a fish and meat and he got this data 85 like meat 125 like fish 70 like both fish and meat 1 what is the probability for a customer to pick at least one item?

Answers

Taking into account the definition of probability, the probability for a customer to pick at least one item is 14/15.

Definition of Probabitity

Probability is the possibility that a phenomenon or an event will happen, given certain circumstances and it is expressed as a percentage.

The probability of any event A is defined as the ratio between the number of cases in which event A may or may not occur and the total number of possible cases. This is called Laplace's Law:

P(A)= number of favorable cases÷ total number of posible cases

Union of events

The union of events, AUB, is the event formed by all the elements of A and B. That is, the event is verified when one of the two, A or B, or both occurs and it is read as "A or B".

The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:

P(A∪B)= P(A) + P(B) -P(A∩B)

where the intersection of events, A∩B, is the event formed by all the elements that are, at the same time, from A and B.

Probability for a customer to pick at least one item

In first place, let's define the following events:

M: The event that a customer like meat.F: The event that a customer like fish.

So you know:

P(M)= 85÷150= 17/30P(F)= 125÷150= 5/6P(F and R)= P(F∩R)= 70÷150= 7/15

In this case, considering the definition of union of events, the probability for a customer to pick at least one item is calculated as:

P(M∪F)= P(M) + P(F) -P(M∩F)

P(M∪F)= 17/30 + 5/6 -7/15

P(M∪F)= 14/15

Finally, the probability for a customer to pick at least one item is 14/15.

How to determine if the expressions are proportional?

The expressions are given as

The constant rate (r) of the expressions is then calculated as

r = y/x

For the expression (64, 96), we have the following computation

r = 96/64

Evaluate the quotient

So, we have

r = 1.5

For the expression (60, 90), we have the following computation

r = 90/60

Answers

Caroline and Rodney, on their way to the canoe livery, stopped to eat lunch at the point on their map with coordinates of (-2, -1).

What is the coordinate of a point?

The coordinates of a point on a two dimensional plane are two numbers that define its location.

The given coordinates of the journey are;

Location of the clubhouse = (-4, -3)Coordinates of the canoe livery = (2, 3)Proportion of the hike completed before they stopped for lunch = (1/3) of the journey

Required; The coordinates of the map where Caroline and Rodney stopped for lunch.

Solution:

The coordinates of a point (x, y), which is a proportion, t, of the distance between two points (a, b), and (c, d) is given by the formula;

x = a•(1 -t) + c•t

y = b•(1 -t) + d•t

The location where they had lunch is therefore;

x = -4×(1 - (1/3)) + (1/3)×2 = -2

y = -3×(1 - (1/3)) + (1/3)×3 = -1

What are linear equations?

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

How to determine the linear equation?

The table represents the given parameters

On the table, we have the following points

(x, y) = (0, 1) and (1, -1)

A linear equation is represented as

y = mx + c

Substitute (x, y) = (0, 1) and (1, -1) in y = mx + c

So, we have

1 = 0 * m + c

-1 = 1 * m + c

This gives

1 = c

-1 =m + c

Rewrite 1 = c as

c = 1

Substitute c = 1 in -1 =m + c

-1 =m + 1

Evaluate

m = -2

Substitute m = -2 and c = 1 in y = mx + c

y = -2x + 1
