Step-by-step explanation:

Answer:

length of rectangle = 4 units

width of rectangle = 3 units

Perimeter of a rectangle = 14 units

Step-by-step explanation:

Properties of a rectangle:

From inspection, we can see that (2, 2) and (2, 6) have the same x-values.  So (2, 6) is above (2, 2) on the same vertical line.  

To calculate the distance between them, find the difference between their y-values:  6 - 2 = 4

Therefore, one pair of sides of the rectangle are 4 units in length.

From inspection, we can see that (2, 6) and (5, 6) have the same y-values.  So (5, 6) is to the right of (2, 6) on the same horizontal line.  

To calculate the distance between them, find the difference between their x-values:  5 - 2 = 3

Therefore, the other pair of sides of the rectangle are 3 units in length.

Therefore:

Perimeter of a rectangle = 2 × length + 2 × width

                                         = 2 × 4 + 2 × 3

                                         = 8 + 6

                                         = 14 units

Answer:

Explaining the concept:

We have been given a piecewise function, which means that this function is defined differently for different values

notice that in the function, at the end of each row, we have an 'if' statement

if the input value satisfies the if statement, the function of that respective row will be used

Finding the Values:

h(-5):

since the input value is unequal to -2, the first function will be used (because the if statement at the end of the first function is satisfied by the input value)

h(x) = -(x/4) - (2)      (since x ≠ -2)

replacing x with -5

h(-5) = -(-5/4) - 2

h(-5) = (5-8) / 4

h(-5) = -3/4

h(-2):

From the 2 if statements, we notice that this input value satisfies the second statement (x = -2)

Therefore, the second function will be used

h(x) = -1 (for x = -2)

h(-2) = -1

h(0):

This input values satisfies the first if statement.

Hence, the first function will be used

h(x) = (-x/4) - 2              (for x ≠ -2)

replacing x with 0

h(0) = (-0/4) - 2

h(0) = -2

Step-by-step explanation:

Hope this helps

Answer:

Using distributive property you jsut multiply the number outside the parenthesis by each number inside.
In this case its
1/2 ( p + 4)

So multiply each number (or variable) by 1/2

And leave the sign if nothing changes

1/2 * p = 1/2p

1/2 * 4 = 2

You’d get
1/2p + 2

product = multiplication

so it's    2 * (x+4) = 22

* = product / multiplication

sum = addition

2 * (x+4) = 22

2x + 8 = 22

2x = 14

x = 7

The amount Cheryl earned from the per time job is $82.

The three of them earned $550 from their part time jobs.

Li Ying earned $28.

Daniel earned 4 times as much as the total amount of Cheryl and Li Ying's earnings.

let

x = amount Cheryl earned

y =  amount Daniel earned

Therefore,

y = 4x + 112

y - 4x = 112

The three of them earned $550. Therefore,

x + y = 522

Let's combine the equation.

y - 4x = 112

x + y = 522

5x = 410

x = 410 / 5

x = 82

Therefore, Cheryl earned $82.

Assume the  cost in dollars of a call, y, is a linear function of the time in minutes, the linear equation that gives the cost of a Sunday call is y = 0.05x + 0.34

The linear equation is represented as follows:

y = mx + b

where

m = slope

b = y -intercept

Therefore,

(44, 2.54)(10, 0.84)

m = [tex]\frac{0.84-2.54}{10-44}[/tex]

m = [tex]\frac{-1.7}{-34}[/tex]

m = $0.05

Therefore,

y = cost in dollars

x = time in minutes

0.84 = 0.05(10) + b

0.84 - 0.5 = b

b = 0.34

Therefore,

y = 0.05x + 0.34

Step-by-step explanation:

1. Convert percentages into fractions or decimals

For fraction: divide 17 by 100 and remove the % sign.

[tex][17][/tex]%[tex]=\frac{17}{100}[/tex]

For decimal: move the decimal point 2 places to the left and remove the % sign.

[tex][17][/tex]%[tex]=0.17[/tex]

2. Multiply the decimal or fraction by the quantity that equals 100%

100%=47

[tex]17/100*47=0.17*47=7.99[/tex]

So hence, 17% is $7.99 of $47

3. Add the Tip with the Cost of the Meal (will give final answer)

to make things easier -

The missing number that will make both expressions to be equivalent expressions is: 110.

Two expressions are equivalent if they have the same value.

Given the following expressions:

Let x represent the missing number in the second expression. Thus, equate both expressions and solve for x.

200r -(-110) = x + 200r

200r + 110 = x + 200r

Add like terms

200r - 200r + 110 = x

110 = x

x = 110

Therefore, the missing number that will make both expressions to be equivalent expressions is: 110.

Step-by-step explanation:

ALEX=54/60×100=90%

Answer:

To find c you know that angles on a straight line equal 180° (supplementary angles). So 70+30+∠C=180.

Now we can solve this.

100+c=180.

Move the 100 over to the other side.

100-100+c=180-100

Simplify.

∠C=80°

Because we know that the two lines with double arrows are parallel, we can use the rule that alternate interior angles are congruent. This means that ∠E=70.

∠E=70°

Since the total sum of the angles in a triangle are equal to 180°, we know that ∠D+∠C+∠E=180. Because we already know ∠C and ∠E we can put those numbers in for them. 80°+70°+∠D=180°. Now we can solve this.

80+70+D=180

Simplify this.

150+D=180

Now we move the 150 over to the other side to get D by itself.

150-150+D=180-150

Simplify.

D=30

∠D=30°

Now we can find the vertical angle opposite ∠A by using the alternate interior angles rule again this time using the parallel lines with only one arrow on them. The vertical angle opposite ∠A=30°. Since vertical angles are congruent ∠A=30°.

∠A=30°

We are going to use the alternate angles rule one more time to solve for ∠B (this rule is very important when dealing with parallel lines), we could also use the corresponding angles rule but for simplicity we will just stick with the alternate angles rule. Because the vertical angle opposite ∠A is equal to 30°, we can see that the supplementary angle opposite ∠B=30°. Because this angle is supplementary with B we know that 30+B=180.Now we can solve this.

30+B=180

Now we move the 30 over to the other side.

30-30+B=180-30

Simplify.

B=150

∠B=150°

Answer:

1/2

Step-by-step explanation:

7/10 - 1/5

=> 7/10 - 1*2/5*2

=> 7/10 - 2/10

=> (7-2)/10

=> 5/10

=> 1/2

first, you have to make sure they have the same bottom number so you would make 1/5 2/10.

7/10-2/10

which is 5/10

you would simplify it and get 1/2 because 5 is half of 10

Answer:

y = 4x + 8

Step-by-step explanation:

parallel mean the same slope so you can start with an equation of:

y = 4x + b

now we solve for b by inserting the coordinates and solving for b:

0 = 4 ( -2) + b

0 = -8 + b

8 = b

now put b into the equation:

y = 4x + 8
