Answer:

A

Step-by-step explanation:

S = (n - 2)180   (divide by 180 on both sides)

[tex]\frac{S}{180}[/tex] = n - 2  ( add 2 on each side)

[tex]\frac{S}{180}[/tex] + 2 = n

Answer:

(x²+3x-88) square units

Step-by-step explanation:

Area of a rectangle = Length × Width

Given

length of a rectangle is (x-8)units

Its width is (x+11) units.

Required

Expression for the area of the rectangle

Substituting the given function into the formula.

Area of the rectangle = (x-8)(x+11)

Area of the rectangle = x(x)+11x-8x-88

Area of the rectangle = x²+3x-88

Hence the expression that represents the area of the rectangle is x²+3x-88 units²

teresa: use difference of 2 squares

rico: 6561 is not a perfect square

pg. 2

i think teresa is right and that 6561 can be broken down

problem 1: (x^4-81)^2=(x^2-9)^4=(x-3)^8

problem 2: a. false b. rico

pg. 3

problem 3: a. -1(3x+5)^2 b. teresa is right because it cant still be a perfect square trinomial while having a negative first term.

problem 4: a. (y+3)^2 b. teresa

pg. 4

problem 5: a. (x^n+y^n)(x^n-y^n) b. teresa

teresa got more right, rico is buying pizza

Step-by-step explanation:

On colum x there just adding by 2 until the 5 on colum y your just adding 6

Answer:

The values of y and x

Step-by-step explanation:

The values are not proportional to each other because each value divided (x÷y and the other way around : y÷x)) does not have the same answer.

Answer:

is this about corona but the answer is 23

Step-by-step explanation:

Answer:

x = 0 and x = 1

Step-by-step explanation:

From the table of values

f(x) = g(x) = 1 when x = 0 , and

f(x) = g(x) = 0.25 when x = 1

The solution to f(x) = g(x) are x = 0 and x = 1

Answer:

113.33 km/hr

Step-by-step explanation:

Given that :

From Austin

Drive 1 : Speed of 120km/hr for 1.5 hours

Stop time = 0.5 hour

Drive 2 : speed of v2 for 45 minutes to finally reach Houston

Total distance (Austin to Houston) = 265 km

Total distance : (distance on drive + distance on second drive)

Distance = speed * time

(120 * 1.5) + (v2 * 45/60) = 265

180 + 0.75v2 = 265

0.75v2 = 265 - 180

0.75v2 = 85

v2 = 85 / 0.75

v2 = 113.33km/hr

v2 = 85 / 0.75

v2 =

y = 1/4x is the answer.

No need for + b because the graph has a y intercept of (0, 0) and will go through the point (4, 1)

Answer:

Step-by-step explanation:

JK + KL = JL

where:

JK = 7x + 8

KL = 2x + 2

JL = 55

plugin values into the equation:

7x + 8 + 2x + 2 = 55

7x + 2x = 55 - 8 - 2

9x = 45

x = 45 / 9

x = 5

KL = 2x + 2

KL = 2(5) + 2

KL = 12

Answer:

for the first one the answer is 28-9=18 and 30-13=17 are not the same but are close and for the second one the answer is $30 for the phone plan cause 200×0.15=30

If you use 50 minutes in a month, both plans will cost $32.50.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

2.

A. Let x be the number of minutes used in a month. Then, the cost of Plan A is given by:

Cost(A) = 0.09x + 28

The cost of Plan B is given by:

Cost(B) = 0.13x + 30

To find the number of minutes that will make the plans cost the same, we need to set Cost(A) equal to Cost(B) and solve for x:

0.09x + 28 = 0.13x + 30

0.04x = 2

x = 50

Therefore, the plans will cost the same if you use 50 minutes in a month.

B. If you use 50 minutes in a month, the cost of Plan A will be:

Cost(A) = 0.09(50) + 28 = 32.50

The cost of Plan B will also be:

Cost(B) = 0.13(50) + 30 = 36.50

Therefore, if you use 50 minutes in a month, both plans will cost $32.50.

3.

A. Let C be the monthly cost and t be the number of text messages sent. Then, the linear model that represents the monthly cost is:

C = 0.15t + base cost

The base cost is the cost for unlimited calling, which is not specified in the problem.

B. If you send 200 text messages, the monthly cost will be:

C = 0.15(200) + base cost

C = 30 + base cost

The total cost will depend on the base cost for unlimited calling.

Step-by-step explanation:

Answer:

Good for him

explanation:

53.82

Answer:

Let's see what to do buddy...

Step-by-step explanation:

If it is 5 + 2/3

_________________________________

Step (1)

First we have to find all she has :

[tex]5 \frac{2}{3} = 5 + \frac{2}{3} = \frac{5 \times 3}{3} + \frac{2}{3} = \\ \frac{15}{3} + \frac{2}{3} = \frac{17}{3} [/tex]

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

[tex] \frac{17}{3} \div 4 = \frac{17}{3} \times \frac{1}{4} = \frac{17}{12} \\ [/tex]

So each of her friends receive 17/12 .

_________________________________

_________________________________

_________________________________

If it is 5 × 2/3

_________________________________

Step (1)

Firs we have to find all she has :

[tex]5 \times \frac{2}{3} = \frac{10}{3} \\ [/tex]

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

[tex] \frac{10}{3} \div 4 = \frac{10}{3} \times \frac{1}{4} = \frac{10}{12} \\ [/tex]

So each of her friends receive 10/12 .

And we're done.

Answer:

40 degrees

Step-by-step explanation:

-10+40=30

Answer :-

30°F – (–10°F)

= 40°F

Answer:

first table, the answer is -1

f(x)=x always rmmbr that so f(3)=-1 bcoz of the value 3 which represents the Term.

in second table, the values are at a 12 difference.

23-12=11, 11-12=-1,-1-12=-13, so -13-12=-25 and so on

second option is correct.

hope you understood best of luck

Answer:

It will take [tex]\frac{19}{101}[/tex] hour.

Step-by-step explanation:

The rule of the distance is:

Distance = speed × time

∵ An object is traveling at a steady speed of [tex]10\frac{1}{10}[/tex] km/h

∴ The speed =  [tex]10\frac{1}{10}[/tex] km/h

∵ The object will travel [tex]1\frac{9}{10}[/tex] km

∴ The distance =  [tex]1\frac{9}{10}[/tex] km

→ We need to find how long will it take it to travel this distance

→ Substitute the values of distance and speed in the rule above

∵  [tex]1\frac{9}{10}[/tex]  =  [tex]10\frac{1}{10}[/tex] × time

→ To find the time divide both sides by  [tex]10\frac{1}{10}[/tex]

∴ The time =  [tex]1\frac{9}{10}[/tex]   ÷  [tex]10\frac{1}{10}[/tex]

→ Change the mixed numbers to an improper fraction

∵  [tex]1\frac{9}{10}[/tex] = [tex]\frac{(1)(10)+9}{10}=\frac{19}{10}[/tex]

∵   [tex]10\frac{1}{10}=\frac{(10)(10)+1}{10}=\frac{101}{10}[/tex]

∴  The time = [tex]\frac{19}{10}[/tex] ÷ [tex]\frac{101}{10}[/tex]

- Reverse the fraction after the division sign, then change ÷ to ×

∴ The time =  [tex]\frac{19}{10}[/tex] × [tex]\frac{10}{101}[/tex]

→ 10 up will cancel 10 down

∴ The time =   [tex]\frac{19}{101}[/tex] h

It will take [tex]\frac{19}{101}[/tex] hour.
