Step-by-step explanation:

You really just need a calculator for this but to solve by hand just simply separate all the variables and coefficients and then multiply them together at the end.

[tex]-9x^5y^2[/tex]

Since x = -1

[tex]-1^5[/tex] = [tex]-1*-1*-1*-1*-1[/tex] = -1

[tex]\frac{1}{3}^2= \frac{1}{3}*\frac{1}{3}=\frac{1}{9\\}[/tex]

[tex]-9*-1*\frac{1}{9}=1[/tex]

Answer:

Cost of child movie = x = $8

Cost of adult movie = y = $10.25

Step-by-step explanation:

Let cost of child movie = x

Cost of adult movie = y

Now converting statements into mathematical expressions:

Hansen family bought 2 child and 2 adult movie tickets and paid $36.50.

[tex]2x+2y=36.50[/tex]

Owens family bought 5 child and 2 adult tickets and paid $60.50. [tex]5x+2y=60.50[/tex]

Let:

[tex]2x+2y=36.50--eq(1)\\5x+2y=60.50--eq(2)[/tex]

Subtract both equations:

[tex]2x+2y=36.50\\5x+2y=60.50\\- \:\:\: - \:\:\:\:\:\:\:\: -\\--------\\-3x=-24\\x=\frac{-24}{-3}\\x=8[/tex]

So, we get Value of x =8

Now, putting value of x in eq(1) to find value of y

[tex]2x+2y=36.50\\Put \: x=8\\2(8)+2y=36.50\\2y=36.50-16\\2y=20.5\\y=\frac{20.5}{2}\\y=10.25[/tex]

So, we get Value of y = 10.25

So,

Cost of child movie = x = $8

Cost of adult movie = y = $10.25

Step-by-step explanation:

Equivalent expressions are expressions with equal values

The equivalent expression of 2(14x-3y+28x+12.2-5y-17.5) is 84x-16y-10.6

The expression is given as:

2(14x-3y+28x+12.2-5y-17.5)

Collect like terms

2(14x-3y+28x+12.2-5y-17.5) = 2(14x+28x-3y-5y+12.2-17.5)

Evaluate the like terms

2(14x-3y+28x+12.2-5y-17.5) = 2(42x-8y-5.3)

Open the bracket

2(14x-3y+28x+12.2-5y-17.5) = 84x-16y-10.6

Hence, the equivalent expression of 2(14x-3y+28x+12.2-5y-17.5) is 84x-16y-10.6

Step-by-step explanation:

There is no time when the doctor starts from home, so it is technically impossible to solve.

To solve the equation |11x + 10| = 22, we need to consider two cases: one where the expression inside the absolute value is positive and one where it is negative.

Case 1: (11x + 10) is positive:

In this case, the equation becomes 11x + 10 = 22. Solving for x, we subtract 10 from both sides, resulting in 11x = 12. Dividing by 11 gives x = 12/11.

Case 2: (11x + 10) is negative:

Here, the equation becomes -(11x + 10) = 22. Simplifying, we have -11x - 10 = 22. Adding 10 to both sides gives -11x = 32. Dividing by -11 yields x = -32/11.

Thus, the solution set for the given equation is x = 12/11 and x = -32/11, representing the two possible values of x that satisfy the equation |11x + 10| = 22.

The component form of the vector P'P is [tex]\left \langle -7, 2 \right \rangle[/tex]

Step-by-step explanation:

The component form of the vector that translates P(4, 5) to P'(-3, 7), is given as follows;

The x-component of the vector = The difference in the x-values of the point P' and the point P = -3 - 4 = -7

The y-component of the vector = The difference in the y-values of the point P' and the point P = 7 - 5 = 2

The component form of the vector P'P = [tex]\left \langle -7, 2 \right \rangle[/tex]

The required numbers are 18,46 and 23.

This problem requires the idea of linear equation of 1 variable.

To clear up the linear equation we also need to recognize the BODMAS policies and the way to solve algebraic equations.

in this query the sum of the 3 numbers is 87.

let us count on that the third variable be x.

the second one variable is 2x.

The first variable is (x-5).

Now according to the question,

   [tex](x-5)+2x+x=87[/tex]

⇒ [tex]4x-5=87[/tex]

⇒ [tex]4x=87+5[/tex]

⇒[tex]4x=92[/tex]

⇒ [tex]x=\frac{92}{4}[/tex]

∴ x=23

So, the third number is 23.

The second number is 2x i.e., 46.

The first number is (x-5) i.e., 18.
