Answer: f⁻¹(x)=4x-56

Step-by-step explanation:

f⁻¹(x) is the inverse of f(x). To find the inverse, we replace the y with x, and x with y. Once we do that, we solve for y.

[tex]x=\frac{1}{4}y+14[/tex]                 [subtract 14 on both sides]

[tex]x-14=\frac{1}{4}y[/tex]                 [multiply both sides by 4]

[tex]4(x-14)=y[/tex]               [distribute 4]

[tex]4x-56=y[/tex]

[tex]f^-^1(x)=4x-56[/tex]

Answer:

x° = 62

Step-by-step explanation:

The vertical angle to 28 degrees is 28 degrees in size.

The vertical angle to 90 degrees is 90 degrees in size.

Angles in a circle add up to 360 degrees.

x + 28 + 152 + 28 + 90 = 360

x + 298 = 360

x = 360 - 298

x = 62

Angle x is 62 degrees in size.

Answer:

(-2,7)

Step-by-step explanation:

y=-3x+1  which is equivalent to y+3x=1

y=-x+5  which is equivalent to y+x=5

subtract the two equations :

y+3x-(y-x)=1-5

2x=-4

x=-2

substitute x in one equation : y+(-2)=5

y=5+2=7

check :

y+x=5

7-2=5

y+3x=1

7-6=1

Answer:

The y-intercept is when x = 0 so that means that the y intercept is (0, -8) or -8.

Answer:

Answer A

Step-by-step explanation:

Answer A is correct.  Sides 3.6 and 3 form one ratio and sides 5.4 and 4.5 form another ratio of the lengths of corresponding sides.

Answer: I think it is “the y-value is always positive” because none of the y-values are below the x-axis, which would make them negative. Hope I helped!

Step-by-step explanation:

x^2 = 2018 * 2020 + 1

x^2 = 4,076,361

x = -2019 or x = 2019

Since x < 0, then x = -2019

Answer:

x = 2019

Step-by-step explanation:

2018 * 2020 + 1 = 4076361

sqrt(4076361) = 2019

Answer:

B) 16√t

Average speed of the car =16√t inches per second

Step-by-step explanation:

A) 4√t

B) 16√t

C) 16 / √t

D) 16t

Speed = distance / time

Distance = 16t√t

Time = t

Substitute the value of distance and time into the formula

Speed = distance / time

Speed = 16t√t / t

= 16√t

Therefore, speed = 16√t

Average speed of the car =16√t inches per second

Ans B

Answer:

The third option, or initial value:2, rate of change:1.

Step-by-step explanation:

The initial value is where the y-intercept is on the y-axis. For this problem it falls on the 2.

Your rate of change is your slope. I like to think of it as rise/run. Your slope in this graph is 1/1. Or just 1.

Answer:

y= 2x +12

Step-by-step explanation:

Given:

The line parallel to the given has the same slope of 2, let's find the intercept using the given point:

So the equation is:

Slope intercept form of the equation 8x+2y=0 is y= -4x

Slope intercept form gives the graph of a straight line and is represented in the form of y=mx + c

Given,

8x+2y=0

2y =-8x

y=-4x

Hence, the Slope intercept form of the equation 8x+2y=0 is y= -4x

Answer:

[tex]P(Male) = \frac{1}{3}[/tex]

Step-by-step explanation:

Given

[tex]Male = 4[/tex]

[tex]Female = 8[/tex]

Required

Probability of selecting a male

First, we need to get the total population;

[tex]Total = Male + Female[/tex]

[tex]Total = 4 + 8[/tex]

[tex]Total = 12[/tex]

Let P(Male) represent Probability of Male

Let n(Male) represent number of Male

[tex]P(Male) = \frac{n(Male)}{Total}[/tex]

[tex]P(Male) = \frac{4}{12}[/tex]

Simplify fraction by dividing the numerator and denominator by 4

[tex]P(Male) = \frac{1}{3}[/tex]

Hence, the probability of selecting a male is 1/3

Well in the equation y = x - 42 the 42 is the y intercept and the x is the slope because that’s what x stands for.

Answer:

Krista put 0.40 in the first equation meant for the number of stamps.

Step-by-step explanation:

Krista's equation

0.40x+y=45

x+0.55y=18.75

The system of Equation should have been

x + y = 45 (1)

0.40x + 0.55y = 18.75 (2)

From (1)

x=45-y

Substitute x=45-y into (2)

0.40(45 - y) + 0.55y = 18.75

18 - 0.40y + 0.55y = 18.75

Collect like terms and you now have

0.55y - 0.40y = 18.75 - 18

0.15y = 0.75

Divide both sides of the equation by 0.15

y = 5

Substitute y=5 into (1)

x + y = 45

x+5=45

x=45-5

x=40

This shows that the stamps that cost 0.40 cents were 40 while those that cost 0.55 cents were 5 in number.

Krista's error:

Krista put 0.40 in the first equation meant for the number of stamps.

Answer: A, Krista put 0.40 in the first equation meant for the number of stamps.

Answer:

A) Point C

B) Point E

Step-by-step explanation:

There are 3 vowels in the word square, and there are six total letters in the word square.

Square

There is a half chance of picking a letter that is a vowel in the word "square". (Three is half of six.)  

Point C would be the most accurate spot for question 'a'.

The word square does not have a 'T'. It is certain that a letter that is not 'T' would be picked.

Point E would be the most accurate spot for question 'b'.

Answer:

a)  c  b) e

Step-by-step explanation:

There are 3 vowels out of 6 total cards, and c lands at 3/6->1/2.

There is no letter T, so it is a 1/1 chance of not getting a T. E lands at 1.

Answer:

The correct options are:

(8,4)

(16,8)

Step-by-step explanation:

The table is given which shows the number of yellow tiles and red tiles.

The first row in the table shows that if there are 4 red tiles then there will be 2 yellow tiles. This relation can be defined as the number of red tile will always be double the amount of number of yellows tiles. Carter graphs this point as (4,2) where number of red tiles are plotted on x axis and number of yellow tile are plotted on y axis.

Consider the second row of the table. Number of red tiles is 8 while number of yellow tiles is 4, so the point he plots on the graph is (8,4)

Similarly, other points are (12,6) and (16,8)

Answer:

It's (8, 4) and (16, 8)

area of 1 face and surface area

Step-by-step explanation:

The missing options are:

In the picture attached, the cube measurements are shown:

In a linear relationship:

variable a / variable b = k

Case: side length and perimeter of 1 face

12/3 = 16/4 = 20/5 = 24/6 = 4

Case: perimeter of 1 face and area of 1 face

12/9 ≠ 16/16 ≠ 20/25 ≠ 24/36

Case: surface area and volume

54/27 ≠ 96/64 ≠ 150/125 ≠ 216/216

Case: area of 1 face and surface area

54/9 = 96/16 = 150/25 = 216/36 = 6

Case: side length and volume

27/3 ≠ 64/4 ≠ 125/5 ≠ 216/6

The side length and the perimeter of one face have a linear relationship.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

From the graph:

The side length and the perimeter of one face have a linear relationship.

Answer:

8 1/2

Step-by-step explanation:

It is already rounded to the nearest half.

Answer:

a) 78°

b) 39°

Step-by-step explanation:

In circle with center O, DE is tangent at point A and AC is chord (or secant if extended both sides).

Therefore by tangent secant theorem.

[tex] m\angle CAE = \frac{1}{2} \times m\widehat{(AC)} \\\\

\therefore 39\degree = \frac{1}{2} \times m\widehat{(AC)} \\\\

\therefore m\widehat{(AC)} = 39\degree\times 2\\

\red{\bold{\therefore m\widehat{(AC)} = 78\degree}}\\[/tex]

Since, measure of central angle of a circle is equal to the measure of its corresponding minor arc.

[tex] \therefore m\angle AOC = m\widehat{(AC)}\\

\huge \purple {\boxed {\therefore m\angle AOC = 78\degree}} \\[/tex]

Next, by inscribed angle theorem:

[tex] m\angle CBA = \frac{1}{2}\times m\widehat{(AC)}\\\\

\therefore m\angle CBA = \frac{1}{2}\times 78\degree \\\\

\therefore m\angle CBA =39\degree \\\\

\huge \orange{\boxed {\therefore m\angle OBA = 39\degree}}\\... (\because C-O-B) \\[/tex]
