Answer:

Tom wants to go to disneyland this weekend with 23 adults including himself and 4 children Ashley 3, Leslie 1, Brit 4, Victor 2. Children under the age of 6 pay "x" amount while anyone older pay "y" amount. What equation can tom use to find out how much the tickets in total will be.

Step-by-step explanation:

Y = Adults pay y amount - There are 23 adults

X =kids under 6 pay x amount - there are 4 children

4x+23y

4 (kids under 6 ticket cost)+ 23 (Adults ticket cost)

Answer:

No, The answer is 20. Remember area of triangle equals 1/2bh (or half of base and height multiplied.)

The area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.

The area of a triangle is one half the product of its base multiplied by height. Mathematically -

Area [Δ] = 1/2 x base x height

Given is a triangle (Δ) has a base length of 10 inches and a height of 4 inches.

We can write -

Base Length [B] = 10 inches

Height of triangle [H] = 4 inches

Area of triangle (Δ) = 1/2 x B x H

A(Δ) = 1/2 x B x H

A(Δ) = 1/2 x 10 x 4

A(Δ) = 20 square inches

Therefore, the area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.

For eliminate a variables we need addition method or elimination method.

In an equation or formula, a variable is a symbol or letter that stands in for an unknowable or varying quantity or value.

We can multiply the second equation by -2, so that the coefficient of x in both equations will be the same but with opposite signs:

⇒ 4x - 9y = 8

⇒ -4x - 6y = -48

Add the two equations together: ⇒ -15y = -40

⇒ y = 8/3

Substitute this value of y back into either equation to solve for x.

⇒ 4x - 9(8/3) = 8

⇒ 4x - 24 = 8

⇒ x = 8

Therefore, the steps to eliminate a variable in this system using the addition method are to multiply the second equation by -2, add the two equations together to eliminate the x variable, solve for y, and then substitute that value back into either equation to solve for x.

Answer:

90000

Step-by-step explanation:

Y = x(600 - x)

Let's rearrange the equation so that we have

Y = x(-x + 600)

Y = -x² + 600

When you take a look at parabolas, we know that their maximum or minimum values are usually on the axis of symmetry. This axis of symmetry has an equation of

x = -b/2a,

In this question, the axis of symmetry is

x = -600 / -2

x = 300

This means that planting 300 trees will maximize your yield. If you substitute for x = 300 into the equation, the maximum yield will be

y = 300 (600 - 300)

y = 90000.

Answer: 300

Step-by-step explanation:

use the formula X=-b/2a

x=-600/-2

x=300

The image of (2,8) after a reflection over the line y = x is (8, 2).

The given coordinate is (2, 8).

Reflect over the y = x: When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places.

When we reflect (2, 8) over the line y=x, we get the coordinate as (8, 2). Because the x-coordinate and y-coordinate changed places.

Therefore, the image of (2,8) after a reflection over the line y = x is (8, 2).

Step-by-step explanation:

Photo given in the picture has dimensions as,

Length = 4 in.

Width = 5 in.

This photo is the reduced form of a photo having dimension 16 by 20 inch print.

Since scale factor of an image is given by,

Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original picture}}[/tex]

                    = [tex]\frac{4}{16}[/tex]

                    = [tex]\frac{1}{4}[/tex]

Therefore, scale factor used to reduce the picture is [tex]\frac{1}{4}[/tex].

Option (B). will be the correct option.

Answer:

it's 4

it's 1:4 cause 16/4 is 4 so the scale factor is 4

Answer:

x+(x+6)=60

Since the greater number is six more than the smaller number, the variable value will be of the smaller number. And since the bigger number is six more than the smaller number, it needs to be in parantheses as x plus six. But, since the value of both the numbers is sixty, the equation will finally become x+(x+6)=60
