Step-by-step explanation:

because the taxi charge $2 + $2.35 per mile and < means you spend less than $47.

Answer: 0.65 + 0.78s

Step-by-step explanation:

From the question, we are informed that Ray wants to buy a hat that costs $10 and some shirts that cost $12 each and that the sales tax rate is 6.5%.

We are further told that the expression 0.065(10+12s) can be used to calculate the amount of sales tax that Ray will pay on his entire purchase.

Therefore, expanding the expression will give:

= 0.065(10+12s)

= (0.065 × 10) + (0.065 × 12s)

= 0.65 + 0.78s

Answer:

this is not equal to zero

Step-by-step explanation:

Complement to 60° = 30°

cos(30°) = sin(60°) = 0.866

Answer:

0.866.

Step-by-step explanation:

We use the identity

sin x = cos (90-x)

So the cosine of the complementary angle is also 0.866.

Answer:

The parallel sides are:

- FG and MN

- GN and FM

Step-by-step explanation:

The question is incomplete, as the image of the square is not attached.

However, I will answer this question using a general rule.

When a square is named ABCD, it means that AB and DC are parallel sides & BC and AD are also parallel

Using this logic, the parallel sides of FGNM are:

- FG and MN

- GN and FM

The diagonals are:

FN and GM

Answer:

Option B

Step-by-step explanation:

Option A, C and D have x- values that repeat and you cannot have that.

Y values can repeat but not x-values.

Option B has all x values with different y-values

Answer:

B.

Step-by-step explanation:

an output can have more than one input but an input can only have one output

basically only one arrow can go from the input to the output and b is the only one who's graph thing is like that

Answer:

x=-4     y=-7

Step-by-step explanation:

-4x+y=9     get y alone

add 4x both sides

y=4x+9

insert into y=2x+1

2x+1=4x+9

subtract 1 both sides

2x=4x+8

subtract 4x both sides

-2x=8

divide by -2

x=-4

y=2x+1

y=2(-4)+1

y=-8+1

y=-7

check

-4(-4)+(-7)=9

-16+(-7)=9

9=9

x=-4

y=-7

History of algebra

Algebra can essentially be considered as doing computations similar to those of arithmetic but with non-numerical mathematical objects. However, until the 19th century, algebra consisted essentially of the theory of equations. For example, the fundamental theorem of algebra belongs to the theory of equations and is not, nowadays, considered as belonging to algebra (in fact, every proof must use the completeness of the real numbers, which is not an algebraic property).

This article describes the history of the theory of equations, called here "algebra", from the origins to the emergence of algebra as a separate area of mathematics.

Answer:

Option 1 is a linear function.

Answer:

74

Step-by-step explanation:

Since two sides of the triangle are equal in length, we know that the remaining two angles are equal as well.

So, 180 - 32 = 148. 148 / 2 = 74.

Answer:

Im not sure what type of solution you are looking for. You should be more specific. Though I will still give you some helpful solutions and you use the one you need.

Step-by-step explanation:

Factored: y=168x+67y-49

Solved for Y; -28x/11 + 49/66

Solved for X: -11y/28 + 7/24

X and Y intercepts:

X=( 7/24, 0 )

Y= ( 0, 49/66 )

I hope these answers help. Next time be more specific to what your looking for and make sure your equation is written correctly.

Answer:

D = 35

multiply 5 time 7 and you get 35

Answer:

The answer to this question is A

The new coordinates will be C( 3 ,0),  D( 7,1) , E(2,4) , Option A is the correct answer.

When a object or a figure is reflected , it means an mirror image if the object is being created , the shape and size of the object remains same , Only the coordinates change on the basis of the axis used for Reflection.

The figure is given in the question.

The coordinates of the figure is

C( -3 ,0)

D( -7,1)

E(-2,4)

When reflection is done along any axis , the coordinates of the other axis change sign.

so in this case ( x,y ) -----> ( -x,y)

The new coordinates will be

C( 3 ,0)

D( 7,1)

E(2,4)

Therefore Option A is the correct answer.

Answer:

[tex]-19,-8,0,\frac{1}{4}, \frac{1}{2}[/tex]

Step-by-step explanation:

Skills required: Ordering a set of numbers

1) [tex]-8,-19,0,\frac{1}{4}, \frac{1}{2}[/tex] are the numbers we are given. There are 2 important things to think about when ordering this set.

2) Based on this, we can split the 5 numbers into 3 groups:

3) Starting with the negative group, we can easily find which number is greater.

-1 is greater than -2.

-23 is greater than -35.

Based on this: -8 is greater than -19. That means when ordering our numbers, -8 is the first number, and -19 is the second number

4) 0 is the 3rd number, since it is less than positive numbers and greater than negative numbers

5) Now onto the positive numbers, which is also easily solvable.

When you have two fractions, there are different ways to find out which fraction is greater than the other. I will show you 2 different ways here.

This means that [tex]\frac{1}{4}[/tex] is the 4th number, and [tex]\frac{1}{2}[/tex] is the 5th term.

Our ordered pair would then be: [tex]-19,-8,0,\frac{1}{4}, \frac{1}{2}[/tex]

Hope this helps and have a nice day!! :) :] :D

Step-by-step explanation:

ok so for number 1 you first have to group the like terms therefore you will now have:

9r-4r+8-6

and now you calculate:

9r-4r=5r

8-6=2

so that means 5r-2 is simplied version for no.1

for number you 2 you first multiply why is inside the brackets by what is in the outside:

2(x+3y)

2x+6y (simplified version)

hope this helps! no problem

Answer: 204 square inches

Step-by-step explanation: I’m not really sure, but if you follow through with the normal area identifying method; Length x Width, you should come up with 25.5. After doing this, you could multiply your product by 8 because your actual mirror size is 8 times greater. You will come up with 204 square inches, which would be your final solution. (Once again, I am not sure, just doing how I’ve been understanding from studies).
