Answer From Gauth Math

The maximum value of n (A ∩ B) occurs when A ⊂ B (i.e. when A is a subset of B), in which case A ∩ B = A, and so max{n (A ∩ B)} = n (A) = 11.

Answer:

A. (3,-4)

Step-by-step explanation:

Hi there!

When we reflect a point (x,y) across the y-axis, it will become the point (-x,y).

Right now we can see that point G has the coordinates (-3,-4). Therefore after reflecting about the y-axis, it would become (3,-4).

I hope this helps!

Answer:

x = -7

Step-by-step explanation:

First we find the slope using

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

   = ( -8 - 5)/( -7 - -7)

   = (-8-5)/(-7+7)

   = -13/0

This means the slope is undefined and the line is vertical

Vertical lines are in the form

x= constant and the constant is the x value of the points

x = -7

Answer:

3 hours

Step-by-step explanation:

t = time to make a table

c = time to make a chair

t + c = 5

t+3c = 9

Subtract the second equation from the first

t+3c = 9

-(t + c = 5)

-----------------------

       2c = 4

Divide by 2

2c/2 = 4/2

c =2

2 hours for the chair

t+c = 5

t+2 = 5

t = 5-2

t = 3hours

Answer:

It takes 3 hours to make a table.

Step-by-step explanation:

Table and chair : 5 hours

Table and 3 chairs : 9 hours

(Table and 3 chairs) - (Table and chair) = (2 chairs)

9 hours - 5 hours = 4 hours

2 chairs : 4 hours / 1 chair : 2 hours

Table and chair : 5 hours

Chair : 2 hours

Table: x hours

5 - 2 = 3

Table : 3 hours

Answer:

25%

Step-by-step explanation:

let the MP be x

sp without vat =x-16%of x

= 21x/25

sp with VAT = 21x/25 +13% of 21x/25

rs 9492 = 2373x/2500

( 9492*2500)/2373=x

x = 10000

cp = ((21x/25 )*100)/100+5 ( 5= profit percent )

=8000

(10000-8000)×100%/8000

Answer:

No

Step-by-step explanation:

Find a number you can multiply 2 by to get 4.

2

Okay, now to ensure the ratio stays the same, multiply by 2/2 (aka 1)

You'll get 4/2, 2hixh is NOT equal to 4/8. So no, these ratios aren't equal.

Hope this helps!

Answer:

A

Step-by-step explanation:

tan(3x/4)=sin(3x/4)/cos(3x/4)

So the domain of tah(3x/4) is all real numbers except real numbers that make cos(3x/4)=0.

cos(pi/2 +n pi)=0

So we need to solve 3x/4=pi/2+n pi

Multiply both sides by 4/3: x=4/3(pi/2+n pi)

Distribute: x=2pi/3+4n pi/3

Or x=(2pi+4 n pi)/3

Or x=2 pi/3 ×(1+2n)

So odd integer multiples of 2pi/3 is the numbers to be excluded from the domain.

The required domain of the function y = 5/3 tan(3/4x) is  (-∞, ∞) - {- 2/3 (2n + 1)π, 2/3 (2n + 1)π}.

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.

y = 5/3 tan(3/4x)
Function tan defined at every x except x = nπ/2 where n = odd number. i.e x = (-∞,∞) - {(2n+1) * π/2, -(2n+1) * π/2}

3/4 * x = (2n + 1 ) * π/2
x = (2n + 1) * 4/3* π/2
x = 2/3 (2n + 1)π
So the required domain for the given function y = 5/36tan(3/4)x is given as,
Domain (x) = (-∞, ∞) - {- 2/3 (2n + 1)π, 2/3 (2n + 1)π}.

Thus, the required domain of the function y = 5/3 tan(3/4x) is  (-∞, ∞) - {- 2/3 (2n + 1)π, 2/3 (2n + 1)π}.

Hi! I'm happy to help!

First of all in this question, we need to find out the total amount Eric paid.

Let's add the two values together.

1.29+0.39=$1.68

If he spent $2, we need to subtract the amount he owed, to get the amount of change.

2.00-1.68=$0.32

Now that we know he receives 32 cents in change, we have to find out which picture that is in.

This top left photo shows two dimes and two pennies. Dimes are worth ten cents and pennies are worth one.

10+10+1+1=22

The top left photo show 22 cents so that is incorrect.

The top right photo shows a quarter, a dime, and two pennies. A quarter is worth 25 cents.

25+10+1+1=37

The top right photo shows 37 cents so that is also incorrect.

The bottom left photo shows a quarter, a dime, a nickel, and two pennies. A nickel is worth 5 cents.

25+10+5+1+1=42

The bottom left photo shows 42 cents, so that is also incorrect.

The bottom right photo shows a quarter, a nickel, and two pennies.

25+5+1+1=32

The bottom right photo shows 32 cents so that one is correct.

You should select the bottom right photo.

Answer:

$67

Step-by-step explanation:

If Chloe spent $67 and now has no money left, that means she only had $67 before her purchase.

Answer:

Starting with the first one, we need to convert both of the equations into slope-intercept form. y = -2x + 5 is already in that form, now we just need to do it to 4x + 2y = 10.

2y = -4x + 10

y = -2x +5

Since both equations give the same line, the first one has infinite solutions.

Now onto the second one. Once again, the first step is to convert both of the equations into slope-intercept form.  

x = 26 - 3y becomes

3y = -x + 26

y = -1/3x + 26/3  

2x + 6y = 22 becomes

6y = -2x + 22

y = -1/3 x + 22/6

Since the slopes of these two lines are the same, that means that they are parallel, meaning that this one has no solutions.  

Now the third one. We do the same steps.  

5x + 4y = 6 becomes

4y = -5x + 6

y = -5/4x + 1.5

10x - 2y = 7 becomes

2y = 10x - 7

y = 5x - 3.5

Since these two equations are completely different, that means that this system has one solution.

Now the fourth one. We do the same steps again.  

x + 2y = 3 becomes

2y = -x + 3

y = -0.5x + 1.5

4x + 8y = 15 becomes

8y = -4x + 15

y = -1/2x + 15/8

Once again, since these two lines have the same slopes, that means that they are parallel, meaning that this one has no solutions.  

Now the fifth one.  

3x + 4y = 17 becomes

4y = -3x + 17

y = -3/4x + 17/4

-6x = 10y - 39 becomes

10y = -6x + 39

y = -3/5x + 3.9

Since these equations are completely different, there is a single solution.  

Last one!

x + 5y = 24 becomes

5y = -x + 24

y = -1/5x + 24/5

5x = 12 - y becomes

y = -5x +12

Since these equations are completely different, this system has a single solution.

hope this helps you out:)
