The Problem Requires To Show The Work, And Provide Justification Statements That Are Mathematically Correct

Answers

Answer 1

Answer:

Step-by-step explanation:

From the table you have points (-1, 3) and (2, 9)

general equation

y-y1 = m (x-x1)

the slope m= (y2-y1) / (x2-x1) = 9-3/ 2+1 = 6/3 =2

so the equation shhould be

y+1=2(x-3)

Sydney equation is wrong because her slope is wrong 1/2

Un groupe d'amis décide d'organiser une sortie au restaurant. Ils prennent contact avec un restaurateur qui leur propose une formule à 20 € par convive. Le jour de la sortie, cinq personnes ne peuvent venir. Les participants doivent alors payer 22 € par personne. Combien de personnes étaient initialement prévues ?

Answers

Answer:

55

Step-by-step explanation:

Assuming that, initially, there were x people at the time of planning.

As given that, initially, the cost for 1 person = € 20

So, Total cost = € 20x ...(i)

As on the day of the outing, five people cannot come, so the number of people on the outing = x-5.

Now, due to the lesser number of people, i.e (x-5), the cost for 1 person = € 22.

Total cost = € 22(x-5) ...(ii)

As total cost remains the same, so equation the total cost from equations (i) and (ii), we have

[tex]20x= 22(x-5) \\\\\Rightarrow 20x=22x-22\times 5 \\\\\Rightarrow 22x-20x= 110 \\\\\Rightarrow 2x=110 \\\\\Rightarrow x=110/2=55.[/tex]

Hence, at the time of planning, there were 55 people.

first one, x = 90
second one, x = 10, 5x = 50, 2x = 20

Answer:

For the first picture, x = 126 and therefore x - 30 = 96

Second picture:

Step-by-step explanation:

since the sum of the angles is 540°, we can say that

x + x + (x - 30) + (x - 30) + (x - 30) = 540

5x - 90 = 540

5x = 630

x = 126

therefore x - 30 = 96°

_____________________________________

2nd picture

we use the same method as we did in the first picture:

5x + 2x + 110 = 180

7x + 110 = 180

7x = 70

x = 10, 5x = 50, 2x = 20

On the radio one morning, a weather reporter stated that the tempature was two degrees below zero, but the tempature would cotinue to rise throughout the day. Which inequality can be used to represent readings, T, that day? A. T < -2 B. T < -2 ( _ UNDER < ) C. T > - 2 D. T > -2 ( _ UNDER >)

Answers

Answer:

T ≥ -2

Step-by-step explanation:

Given

Temperature = 2° below 0°

Required

Represent as an inequality

First, we need to calculate the temperature in the morning.

2° below 0 means.

Temperature = 0° - 2°

Temperature = -2°

Next, we determine the temperature at any time.

The question says the temperature continues to rise during the day.

Represent this with T

This means T will be greater than -2°

However, we need to consider where the temperature started from.

In other words, T = -2

Combine T = -2 and T = -2 together, we have:.

T ≥ -2

Hence, the inequality that represents the scenario is T ≥ -2

Harley was eating pizza and had already eaten six pieces before his sister, Samantha, got home. Samantha was worried that she was not going to get a fair share of the pizza and wanted to know how many pieces were in the pizza originally. Harley told her, "I have only eaten 3/8 of the pizza. How many slices where in the pizza when it was whole

Answers

Answer:

16 pieces of pizza when the pizza was whole.

Step-by-step explanation:

You know that 6 pieces are equal to 3/8 of the pizza.

Let x represent the total number of pieces and write an equation:

3

-- times x = 6

8

Multiply each side of the equation by 8:

8 times 3

            -- x = 8 times 6

            8

3x = 48

Divide each side of the equation by 3:

3x     48

---  =  ---

3        3

x = 16

Step-by-step explanation:

Which of the following is not an ordered pair from the function f(x) = -3x + 4?
A. (2,-2)
B. (5, -11)
C. (-3, 13)
D. (-6, 21)

Answers

Answer: D


Explanation: For this problem you can substitute f(x) and x for 21 and -6 respectively.

Thus, we have 21=-3(-6)+4

The correct answer is D. (-6, 21), as it is not an ordered pair from the function f(x) = -3x + 4.

To determine which of the ordered pairs is not from the function f(x) = -3x + 4, we need to substitute the x-value of each ordered pair into the function and check if it matches the corresponding y-value.

A. (2, -2)

Substituting x = 2 into the function: f(2) = -3(2) + 4 = -6 + 4 = -2

The y-value (-2) matches the given ordered pair. This is a valid solution.

B. (5, -11)

Substituting x = 5 into the function: f(5) = -3(5) + 4 = -15 + 4 = -11

The y-value (-11) matches the given ordered pair. This is a valid solution.

C. (-3, 13)

Substituting x = -3 into the function: f(-3) = -3(-3) + 4 = 9 + 4 = 13

The y-value (13) matches the given ordered pair. This is a valid solution.

D. (-6, 21)

Substituting x = -6 into the function: f(-6) = -3(-6) + 4 = 18 + 4 = 22

The y-value (21) does not match the given ordered pair (-6, 21). This is not a valid solution.

Therefore, the correct answer is D. (-6, 21), as it is not an ordered pair from the function f(x) = -3x + 4.

The Exterior Angle Theorem states that the measure of the exterior angle of a triangle is

equal to the sum of the measures of the two remote interior angles of the triangle. Angle

PMU is an exterior angle to nPBM and its corresponding remote interior angles are /PBM

and /BPM. So, I can calculate the sum of those two angle measures to find the measure

of /PMU

what is the value of x in the triangle 50° and 55° in the bottom with x at the top 50 on the left 55 on the right

Answers

So, we know that the internal angles of a triangle add up to 180 degrees, yes?  

60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.

Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!
