Tristan has $18 in his wallet. He plans to spend $3 per day on lunch. The equation y=−3x+18 represents the total amount of money he has after x days. Graph the equation.

Answer:

f(x) = x²    increases at a faster rate than g(x) = 2x.

f(x)

Reason:

x =  0,   1,   2,   3,   4,   5,   6,   7

f(x) = 0,   1,  4,  9,   16,  25,   36,   49

g(x) = 0,  2,  4,   6,    8,  10,    12,    14.

Comparing the values of f(x) and g(x), we can see that that of f(x) are far higher than that of g(x) for the same values of x.

So f(x) increases at a faster rate.

Answer:

Valid solutions

(20,20)

(32,12)

(6,36)

Invalid solutions

(-4,40)

(36,-8)

(15,22.5)

Step-by-step explanation:

First, plot each point on the graph to determine whether it lies in the solution set.

All the points lie within the shaded region, so they are all solutions to the inequality.

Now, consider restrictions to the domain and range. Since x is the number of wallets and y is the number of hats, each x- and y-value must be a positive whole number. That leaves only the following points as valid solutions.

(20,20)

(32,12)

(6,36)

Answer:

Starting time = 11:43 pm last night

Step-by-step explanation:

The time that her train started from the station is as follows

Given that

Grandparents reached the place at 9:20AM

The travelled time is 9 hours and 37 mins i.e. 9:37 hours

Starting time = Reached time - journey time

Starting time = 9:20 am - 9:37 hrs

= 11:43 pm last night

Answer:

- 10.35°C

Step-by-step explanation:

Given that :

Temperature at 6 AM for four consecutive days :

X : -12.1°C, -7.8°C, -14.3°C, and -7.2°C

The average temperature :

ΣX / n

n = sample size = number of days = 4

[(-12.1) + (-7.8) + (-14.3) + (-7.2)] / 4

= - 41.4 / 4

= - 10.35°C

Hence, the average 6 AM temperature for the four days is - 10.35°C

Answer:

the  height of the pole is 220 centimeters

Step-by-step explanation:

The computation of the height of the pole is shown below

Here we applied the pythagoras theorem

Given that

Hypotenuse = 221 = c

And, base = 21 cm = b

a^2 + b^2 = c^2

So, the height is

= 21^2 cm - 221 cm

= 441 cm - 221 cm

= 220 cm

Hence, the  height of the pole is 220 centimeters

Answer:

4√3/3 and 8√3/3

Step-by-step explanation:

For a 30-60-90 triangle, the ratio of the sides according to the side facing the respective angle is;

1 : √3 : 2

So from what we have ;

Root 3 is 4

a : 4 : b

1 : √3 : 2

From the options, we have our answer as the 30 being half of the 90

So that is;

4 √3/3 and 8 √3/3

it would be about 51 or 52 percent exact but if you have to round about 50 percent was taken off the shirt.

Answer:

1. C   Add/subtract the same quantity to/from both sides

2. A  Yes

Step-by-step explanation:

Start with Equation A.

3x - 1 = 7

Add 1 to both sides.

3x = 8

First question:

How can we get Equation B from Equation A?

Answer:

C   Add/subtract the same quantity to/from both sides

Second question:

Based on the previous answer, are the equations equivalent?

Since by doing a valid step (adding 1 to both sides) Equation A became Equation B, the two equations are equivalent.

Answer:

A  Yes

Answer:

Area = 3,656.6 m²

Step-by-step explanation:

Area enclosed by the track is composed of two semicircles and a rectangle.

Area = area of two semicircles + area of rectangle

= 2(½*πr²) + L*W

Where,

radius of semicircle (r) = ½of 40 m = 20 m

Length of rectangle (L) = 60 m

Width of rectangle (W) = 40 m

Plug in the values

Area = 2(½*π*20²) + 60*40

Area = 400π + 2,400

Area = 3,656.6 m² (aooroximated to nearest tenth)

Step-by-step explanation:

Answer:

The required table is:

Input                   Output

-1                           3

0                           5

1/2                         6

3                            11

Step-by-step explanation:

The function defined that the output of the function can be determined by multiplying the input by 2 and adding 5.

i.e.

if input = x, then output = 2x+5

We are given

Inputs:  

-1, 0,  1/2 and 3

Thus,

When input x = -1, then output = 2(-1) + 5 = -2+5 = 3

When input x = 0, then output = 2(0) + 5 = 0 + 5 = 5

When input x = 1/2, then output = 2(1/2) + 5 = 1 + 5 = 6

When input x = 3, then output = 2(3) + 5 = 6 + 5 = 11

Therefore, the required table is:

Input                   Output

-1                           3

0                           5

1/2                         6

3                            11
