Write the expression for when you translate the graph of y = |2x|−1 a) one unit up, b) one unit down, c) one unit to the left, d) one unit to the right.

Answers

A) y=|2x|
B) y=|2x|-2
C) y=|2x+1|-1
D) y=|2x-1|-1

The expression for when you translate the graph of y=|2x|−1 is y= |2x-2|-1.

What is an expression?

Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. A function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

We are given that;

y = |2x|−1

Now,

To write the expression for when you translate the graph of y = |2x| - 1, we need to use the rules for vertical and horizontal shifts. The rules are:

To shift the graph up or down by k units, add or subtract k to the original function.

To shift the graph left or right by h units, add or subtract h to the input variable.

Using these rules, we can write the expressions for each translation as follows:

a) One unit up: y = |2x| - 1 + 1 y = |2x|

b) One unit down: y = |2x| - 1 - 1 y = |2x| - 2

c) One unit to the left: y = |2(x + 1)| - 1 y = |2x + 2| - 1

d) One unit to the right: y = |2(x - 1)| - 1 y = |2x - 2| - 1

Therefore, by the expression the answer will be y = |2x - 2| - 1.

-8 1/3 + 3 2/5

lol i need a refresh when you multiply the fraction to get it to be added with the other one do you multiply the whole number too?

Answers

Answer:

-81/3+32/5

-81×5+32×3/15

-243+96/15

-147/15

-49/5 Ans

To answer your question ("do you multiply the whole number too?"): Yes, you have to multiply the whole number as well. You can't just separate 1/3 from -8 and multiply it with 2/5, because the whole number is part of the mixed #. Whenever you multiply, add, divide, subtract, or do anything to two mixed numbers, you must include the whole term.

- - - - - - - - - -

Now your question is addition. Like I said, when you add them together, the whole number and the fractions count as one term.

So basically, -8 1/3 + 3 2/5...

- - - - - - - - - -

1) Find the LCM (least common multiple) of the denominators

The LCM of 3 and 5 is 15. To get from 3 to 15, you have to multiply 3 by 5. Now multiply the numbers of the fraction part only by 5.

1/3 --> 5/15 (as you can see, 1x5 = 5, 3x5 = 15)

Now for 2/5: To get from 5 to 15, multiply 5 by 3. Do the same thing to the numbers in the fraction

2/5 --> 6/15 (2x3 = 6, 5x3 = 15)

***TO CLARIFY, DO NOT MULTIPLY THE WHOLE TERM BY THE NUMBER***

Right: 2x3 = 6, 5x3 = 15, 6/15

Wrong: 2/5 x 5 = 2

- - - - - - - - - -

2) So now that we found a common denominator, change the two terms to -8 5/15 + 3 6/15 (because we had to find the LCM to make life a lot easier)

- - - - - - - - - -

3) We just add them together. Even though they are a term together, you can split them apart and add them together separately thanks to the commutative property of addition*.

Time to split it apart to make life a whole lot easier. -8 5/15 can be split apart into the two terms -8 and 5/15. For 3 6/15, it can be split into 3 and 5/15.

Two options from here on:

Set up a single equation: Put all the terms into one equation. -8 + 3 + 5/15 + 6/15. Solve by adding all the terms together in whichever order you prefer (again, thanks to the commutative property of addition)

It would result in the answer -4 4/15

Or...

Set up two separate equations: Set up an equation for whole numbers, and another one for fractions.

Equation 1: -8 + 3 = -5

Equation 2: 5/15 + 6/15 = 11/15

(6 + 5 = 11)

And we add the sums together. -5 + 11/15 = -4 4/15

And that's it!

- - - - - - - - - -

*Commutative Property of Addition: The sum of the numbers will NOT change even if you change the order of the addends

In a sale, the price of a bike is reduced by 40%
The sale price of the bike is £192
How much did the bike cost before the sale?

Answers

Answer:

£320

Step-by-step explanation:

The sale price is reduced 40% of the actual price

Actual price - 40% = £192

Actual price is the 100% price of the bike.

100% - 40% = £192

60% = £192

60% of the actual price of the bike is £192 but we need to find 100%.

To do that we need to find the price of 1%. To find this value we divide 60 into 192

$192 \div 60 = 3.2$

£ 3.2 is the 1% of the actual price.

To find the actual price (100%), you multiply 3.2 by 100

$3.2 \times 100 = 320$

So the actual price is £320

Hope this helps :)

Step-by-step explanation:

£192 = 60% of the original price (reduced by 40%).

1% of the original price = 60%/60 = 192/60 =

= 64/20 = 16/5 = 3.2

100% of the original price = 100×1% = 100×3.2 = £320

the bike cost £320 before the sale.

the difference of twice a number and 3 is -21

Answers

Answer:

-9

Step-by-step explanation:

To answer this question, you have to know how to translate what is asked in words into equation form.

The word difference means subtractions. For example, the difference of 8 and 3 is 5. In equation form, this means " 8 - 3 = 5 "

To say "twice a number" means to have a number twice, which is multiplication. Since we don't know what the number is, we will call it x.

So to put the proposed question in equation form, we would say "2x - 3 = -21"

Now that we've got the equation, we can now solve for x. To do this, we group the like terms first. In this case it's -3 and -21. The easiest method would be to move the -3 to the other side of the equals sign, but in order to do this we have to change the sign of the -3. So your equation now looks like this

2x = -21 + 3

At this point, we add -21 and positive 3, which equals -18, so now we have

2x = -18

Now, in order to get x by itself, we need to look at the main operation on the left side of the equation. The main operation is multiplication because "2x" really means "2 multiplied by x". So in order to get x by itself, we need to move 2 over to the other side of the equation. Since division is the opposite of multiplication, we divide both sides by 2. If we divide the left side by 2, we are left with x by itself because 2 divided by 2 =1, meaning we have 1x, or simply put, just "x".

However on the other side of the equation, we divide that as well by 2. So -18 divided by 2 is -9

The answer is x = -9

In the diagram of a fan below, CA = 9.5 in. this is the distance from the center to a point on the fans blade. what is the distance point A travels in one rotation of the fans blade

Answers

Answer:

About 59.66 inch

Step-by-step explanation:

To find the circumference you first have to find the diameter which is the double the radius. Since 9.5 is the radius of this circle, the diameter is, 9.5x2=19.

With the diameter of 19, you multiply the 19 with pie which is approximately 3.14. The answer is 19x3.14=59.66

We can use the formula for the circumference of a circle to find the distance point A travels in one rotation of the fan's blade. The distance traveled is the same as the circumference of the circle with radius 9.5 in., which is:

C = 2 * pi * r
C = 2 * pi * 9.5
C = 59.69 in.

So point A travels a distance of approximately 59.69 inches in one rotation of the fan's blade.

Step by step: This is exponential growth. f(x)=a(1+r)^x where a is the original amount, r is the rate, and t is the time (in this case, number of years).
2.8% is equivalent to 0.028.
Because this is exponential growth, you add 1 to 0.028.

Area of five squares = 1289.09 square units

Perimeter = 194.6 units

Step-by-step explanation:

Area of square and perimeter:

First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

$\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units$

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

= 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

= 90 + 42 + 28 + 18.7 + 15.9

= 194.6 units

the area of the five squares is 1289.09 square units

the perimeter is 194.6 units

In the rectangle below, the line MN cuts the rectangle into two regions. Find x, the length of segment NB, so that the area of the quadrilateral MNBC is 40% of the total area of the rectangle.

Answers

The length of segment NB is 0.833

Finding x, the length of segment NB

From the question, we have the following parameters that can be used in our computation:

The rectangle

The area of the rectangle is

Area = (20 + x) * 10

The area of MNBC is

Area = 1/2 * 10 * (x + 20 + x - 5)

Area = 5(2x + 15 )

The area of the quadrilateral MNBC is 40% of the total area of the rectangle

So, we have

5(2x + 15) = 40% * (20 + x) * 10

5(2x + 15) = 4* (20 + x)

When evaluated, we have
