Answer:

B. $x=4$

Step-by-step explanation:

We have been given coordinate of a point (4,7). We are asked to find the equation of the line that has an undefined slope and passes through the given point.

We know that slope of a vertical line is undefined. So the vertical line passing through point (4,7) will have an undefined slope.

The slope of line will be undefined when x-coordinates of all points on the line are equal.

Since the line $x=4$ will have same x-coordinates for all y-coordinates, therefore, option B is the correct choice.

Learn this...it really helps

VUX : vertical line, undefined slope, represented by x = a number
HOY : horizontal line, 0 slope, represented by y = a number

so we need an undefined slope.....that means it is a vertical line.....it is represented by x = a number......and that number is the one in the x position...so ur equation is : x = 4 (because (4,7)...the x digit is 4

Answer:

4 $\sqrt{4}$

Step-by-step explanation:

This is an isosceles and right triangle at the same time

In fact, this triangle is called 45-45-90 special right triangle and the side lengths for this special triangle is as follows:

The sides that see the angle with measure 45 is represented with x

and

The side that sees the angle with measure 90 is represented with x $\sqrt{2}$

one of the sides that has angle measure 45 is given as 4 $\sqrt{2}$

to find the length of BC we we need to multiply 4 $\sqrt{2}$ with $\sqrt{2}$

4 $\sqrt{2}$ * $\sqrt{2}$ = 4 $\sqrt{4}$

22 less than the quotient of an unknown number and 35 is -25.

Agata [3.3K]

-22+(x/35)=-25
add 22 to both sides
x/35=-3
multiply both sides by 35 to cleaf raction
x=-105

number was -105

Why do you have to show work for math

Anton [14]

One of the main reasons you have to show work for math is because your teacher needs to know that you understand the concept. Also, showing work helps your teacher know that you didn't cheat using an online calculator that just gives you an answer.

Anthony can either play 4 hours of video games or read 12 chapters of a book. What is Anthony's opportunity cost of playing one

Leona [35]

Answer:

The opportunity cost of playing an hour of video games is not reading 3 chapters of a book.

Step-by-step explanation:

Given that Anthony can either play 4 hours of video games or read 12 chapters of a book, to determine what is Anthony's opportunity cost of playing one hour of video games, the following calculation must be performed:

4 = 12

1 = X

1 x 12/4 = X

12/4 = X

3 = X

Therefore, the opportunity cost of playing an hour of video games is not reading 3 chapters of a book.

5a (b - c) = d Solve for b

Allisa [31]

Solve for b:
5 a (b - c) = d
Divide both sides by 5 a:
b - c = d/(5 a)
Add c to both sides:
Answer: b = c + d/(5 a)
