What is the base of the expression 11 and 12 square? 3 11 12 21

Answer:

We need to solve this system of equations by substitution:

-6x-2y =20

3y=x

Yu can do it with the letter you decide

You can get the x from the second equation and replace in the first:

3y = x

-6x - 2y = 20 -> -6(3y) - 2y = 20 --> -18y - 2y = 20 --> y=-1

Then we can replace in the second one:

3*(-1) = x ---> -3 = x

So the answer is x = -3, y = -1

Answer:

[tex]f^{-1}(x)=\sqrt{x}+2[/tex]

Step-by-step explanation:

Given function is,

f(x) = (x - 2)²

Step - 1

Rewrite the function in the form of a equation.

y = (x - 2)²

Step - 2

Interchange the variables 'x' and 'y',

x = (y - 2)²

Step - 3

Solve the equation for y,

x = (y - 2)²

y - 2 = √x

y = 2 + √x

Step - 4

Rewrite the equation in the form of a function,

[tex]f^{-1}(x)=\sqrt{x}+2[/tex]

Answer:

x = 146º

Step-by-step explanation:

the sum of two angles on the same side is 180º

x + 34º = 180º                subtract 34º from both sides

x = 146º

Answer:

x=7(y-5)/3 +7

Step-by-step explanation:

y-5=3(x-7)/7

(y-5)×7=3(x-7)

7(x-7)=3(x-7)

7(y-5)/3=x-7

7(y-5)/3+7=x

The answer is 5.

First you do 3 x 5, which is 15, and then you subtract 10 from 15, leaving you with 5.

Answer and Step-by-step explanation:

The bottom right answer choice is the answer.

To find the volume, you do (length × width × height)

And to get the surface area, you do [tex]6(x)^{3}[/tex]

We just have to plug 1 [tex]\frac{5}{8}[/tex]

Where did they get [tex]\frac{13}{8}[/tex]?

They made the mixed fraction into a fraction by multiply 8 by 1, then adding that product to 5.

Which leads us to the answer choice being the bottom right.

Answer:

perimeter = 2√10 + 2√5 ≈ 10.797

Step-by-step explanation:

Perimeter = DA + AB + BC + CD

DA = CB

D(4 , 4)

A(7, 5)

DA = √(7-4)² + (5-4)²

DA = √(3)² + (1)²

DA = √9+1 = √10

AB = CD

D(4, 4)

C(3, 2)

CD = √(4-3)² + (4-2)²

CD = √(1)² + (2)²

CD = √1 + 4 = √5

Perimeter = √10 +√5+√10+√5

                = 2√10 + 2√5 ≈ 10.797

Answer:

The angle is 68.2 degrees

Step-by-step explanation:

Let us have the shorter side as the width

In that case, the opposite will be the length which is 8 cm

The diagonal is the hypotenuse

The short side is the adjacent

The trigonometric ratio that links the opposite and the adjacent is the tan

tan of an angle is the ratio of its opposite to the adjacent

In this case,

tan theta = 8/3.2

theta = arc tan (8/3.2)

theta = 68.2 degrees

Answer:

Step-by-step explanation:

Equation of line with a given slope of a and containing a given point (x₀, y₀):

y - y₀ = a(x - x₀)

a = 3,  x₀ = 5,  y₀ = -1

So:

y - (-1) = 3(x - 5)  

y = 3x - 15 - 1

y = 3x - 16

Answer:

25 tickets

Step-by-step explanation:

Carnival M charges an entrance fee of $5.00 and $0.65 per ticket for the rides. Carnival P charges an entrance fee of $10.00 and $0.45 per ticket for the rides. How many tickets must be purchased in order for the total cost at Carnival M and Carnival P to be the same?

Let

x = number of tickets

Carnival M = 5 + 0.65x

Carnival P = 10 + 0.45x

Equate both cost

5 + 0.65x = 10 + 0.45x

5 - 10 = 0.45x - 0.65x

-5 = - 0.20x

x = -5 / -0.20

x = 25 tickets

25 tickets tickets must be purchased in order for the total cost at Carnival M and Carnival P to be the same
