Answer:

8 sq units

Step-by-step explanation:

area of square in middle is 2 x 2 = 4 sq units

area of one triangle is 1/2(2)(2) = 2 sq units

however, there are two triangles, so you have to double 2 to get 4

4 + 4 = 8

Answer:

8cm^2

Step-by-step explanation:

Method 1: It's a trapezium, so take the top length, (6cm), add it to the bottom length (2cm) = 8cm which is then divided by 2 (4cm) then multiplied by the height (2cm) giving an area of 8cm squared.

Method 2: area of the square = 2 x 2 = 4cm^2

Triangle 1: 2 x 2 = 4, divided by 2 = 2cm^2

Triangle 2: same as triangle 1.

Total: 4 + 2 + 2 = 8cm^2

Answer:

{-2,-1,0,1,2}

Step-by-step explanation:

When we are talking of the range, we are referring to the possible y-values the relation can take

Hence, a set of y-values will represent the range of the relation

we have this as:

{2, 1 , 0, -1 , -2}

Arranging in order, we have ;

{-2,-1,0,1,2}

Answer:

New height = 11/2 ft

New height = 5 + 1/2(N)

Step-by-step explanation:

Given:

Initial height = 5 ft

Grown height = 1/2 ft

Find:

New height

Computation:

New height = Initial height + Grown height

New height = 5 + 1/2

New height = 11/2 ft

Equation;

New height = 5 + 1/2(Number of year)

New height = 5 + 1/2(N)

$4.19 tip

Step-by-step explanation:

23.25 x 0.18 = $4.185

Answer:

x = 14

y = 22

Step-by-step explanation:

y = x + 8

4x - 2y = -12

Solve

_____________

Since we see that the first equation has y alone, we can substitute it into the values of y in the second equation.

4x - 2(x + 8) = -12

Distribute :

4x - (2(x) + 2(8)) = -12

4x - 2x +16 = -12

Combine like terms :

2x + 16 = -12

Subtract 16 from both sides :

2x = -28

Divide 2 from both sides to get x alone :

x = 14

Now that we know what x is, substitute it in the first equation to get y :

y = (14) + 8

y = 22

Answer:

(2 , 10) or x = 2 & y = 10

Step-by-step explanation:

y = x + 8

4x – 2y = -12​

1. Substitute x + 8 in for the y in the other equation.

2. Solve for x

3. Take the solution for x and substitute the number in for the x in y = x + 8.

4. Solve for y.

5. Your answer is the result.

4x - 2(x + 8) = -12                       Distributive Property

4x - 2x - 16 = -12                        Combine like terms

2x - 16 = -12                               Isolate the x, so start by moving -16

    + 16   +16                              

2x + 0 = 4                                  Delete the 0. It is a place holder you don't need

      2x = 4                                 Isolate the x by dividing both terms by 2.

        2    2

        x = 2

y = x + 8                      Substitute the 2 in for x and solve the one step equation.

y = 2 + 8

y = 10

Answer:

9.1

Step-by-step explanation:

Let,

hypotenuse = 12.3 cm

perpendicular = 8.2 cm

base = y cm

(hypotenuse)^2 = (perpendicular)^2 + (base)^2

(12.3)^2 = (8.2)^2 + y^2

151.29 = 67.24 + y^2

151.29 - 67.24 = y^2

.: y^2 = 84.05

y = √84.05

y = 9.1

Answer:

C. 4x

Step-by-step explanation:

Considering the options

A.4 – x - This is the difference between 4 and a number x

B. x + 4 - This is the sum of a number x and 4

C. 4x - This is the product of a number x and 4

D.

From the above, option C which is the product of x and 4 is same as four multiplied by a number.

Answer:

[tex]c = kw[/tex]

Step-by-step explanation:

Given

c varies directly as w

Required

Write the equation

c varies directly as w.

Mathematically, this is represented as:

[tex]c\ \alpha\ w[/tex]

Convert to equation.

[tex]c = kw[/tex]

Where k is the constant of variation

Answer:

Answer:

Number of ice cream cones = 65

Number of sundaes = 49

Step-by-step explanation:

Let

x = number of ice cream cones

y = number of sundaes

x + y = 114 (1)

2x + 3.5y = 301.50 (2)

From (1)

x = 114 - y

Substitute into (2)

2x + 3.5y = 301.50 (2)

2(114 - y) + 3.5y = 301.50

228 - 2y + 3.5y = 301.50

- 2y + 3.5y = 301.50 - 228

1.5y = 73.50

y = 73.50/1.5

y = 49

Substitute y = 49 into (1)

x + y = 114 (1)

x + 49 = 114

x = 114 - 49

x = 65

Number of ice cream cones = 65

Number of sundaes = 49

Answer:

Step-by-step explanation:

Well, the formula to find slope is y2-y1 / x2-x1

Here's an example:

(2,12) (4,24)

12-24 / 2-4 =

-12/-2 or 6

You would use:

(y=mx+b) to find an entire equation, including the y intercept

Answer:

Tax amount = $36.25

Step-by-step explanation:

The tax rate is 7.25%.

We need to find the tax be on a $500 TV.

It can be calculated as follows :

[tex]C=500\times 7.25\%\\\\=500\times \dfrac{7.25}{100}\\\\=\$36.25[/tex]

So, the required tax on $500 TV is $36.25.
