Answer: Gradient is 3 and y-intercept is 15

Step-by-step explanation:

by rearranging the equation so y is on 1 side we get:

y = 3x + 15

the gradient is the number before the x (coefficient)

the y intercept is the number that is not multiplied by the x, in this case 15

Answer:

The relation represented by the ordered pair is not a function

The given parameter is represented as

{(-2, 4), (-1, 3), (0, 2), (-2, 0), (1, 1)}

As a general rule;

For a relation to be considered a function, the following must be true:

One x value must not point to several y values

Using the above as a guide, the ordered pair in the relation are not functions

This is because one x value must not point to several y values

Hence, (d) the ordered pair is not a function

Bob is walking at the rate of 6 kilometer per hours

Jack and Bob leave their houses at 10:00 am walking toward each other and they meet at 10.30 am.

The distance between two houses = 7 kilometer

The speed of the Jack = 8 kilometer per hour

The distance traveled by Jack in 30 minutes = 8 / 2

= 4 kilometer

The remaining distance = 7 - 4

= 3 kilometer

Bob traveled 3 kilometers in 30 minutes

Then the speed of the Bob = 3 × 2

= 6 kilometer per hour

Answer:

4/3

Step-by-step explanation:

so in y=mx+b form.

m=slope b=y-int

Subtract 5 from both sides to isolate y on a side.

4x-6=3y

Divide both sides by 3 to isolate y on one side.

(4/3)x-2=y

y=(4/3)x-2

m=4/3

b=-2

So the slope is 4/3

Answer: x = 1/2 , -3/2

Step-by-step explanation:

Use the quadratic formula:

a=4

b=4

c=-3

x= -4 +- sqrt16-4(4)(-3) / 8

= -4 +- sqrt16+48 / 8

= -4 +- sqrt64 / 8

= -4 +- 8 / 8

Split it to (-4 + 8) / 8 and (-4 - 8) / 8

4/8 and -12/8 = 1/2 and -3/2

The finalized set is { 3 , 4 ,7 , 10 }

Only numerical variables, whether continuous or discrete, can be used to calculate the mean. It is calculated by merely dividing the total number of values in a data set by the sum of all the values in the data set.

The given set is {3,4,7}

3 + 4 + 7 =14

To calculate the mean we divide the sum by the number of numbers present

So we must add 10

because if we add 10 to the set we get

3 + 4 + 7 + 10= 24

Thus the mean = [tex]\frac{24}{4}[/tex]

When we divide these two numbers we get :

mean = 6

The best way Antonio's budget can be modified to help him save enough is D. Antonio could reduce his monthly entertainment expenses by $75 and his food expenses by $50 to pay the monthly rent. He could take $200 out of savings once for the deposit

A budget is an estimate of revenue and expenses for a given period of time that is usually compiled and re-evaluated on a regular basis. A budget expresses intended expenditures as well as recommendations for how to meet them with resources.

Saving is the portion of one's income that is not spent on current expenses. In other words, it is money set aside for future use rather than being spent immediately. An expense is a cost incurred by businesses in the course of their operations. Wages, salaries, maintenance, rent, and depreciation are expenses.

At Letter2go, Betsie can purchase the 250 envelopes. As an example, 250 envelopes cost £31.9 in the Letter2go store but £33.17 in the Value World store.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations.

From Letters 2 go:

Pack of 25 envelopes for £3.19

If we look at the price of envelopes at shop 1, which is Value World,

The cost of a pack of 10 envelopes is £1.99.

Also, buy 2, get one is free

Which means that 1 pack = £1.99

2 packs = 2×£1.99 = £3.98

Also, with 2 packs Betsie get 1 pack free

So, Betsie gets 3 packs for £3.98.

1 pack = 10 envelopes

3 packs = 30 envelopes.

Hence,

In shop Value World:

30 envelopes = £3.98

1 envelope = £3.98/30

250 envelopes = (3.98/30)×250

So, 250 envelopes will cost £33.17 in Shop Value World.

From shop Letter 2 go:

25 envelopes = £3.19

1 envelope = £3.19/25

250 envelopes = (3.19/25)×250

The number of red marbles in the bag is 12.

We are given a bag. The bag contains two types of marbles. There are red and blue marbles in the bag. The ratio of marbles is four red marbles to thirteen more blue marbles than red marbles. Let the ratio of the number of red marbles to that of blue marbles be denoted by the variable "r".

r = 4/(13 + 4) = 4/17

The number of red marbles and blue marbles in the bag is 4x and 17x, respectively, where "x" is a variable. We know that the number of blue marbles in the bag is 51. We can write the following equation to find the value of "x".

17*x = 51

x = 51/17 = 3

Hence, the number of red marbles is 4x = 4*3 = 12.

Answer:

24 people

Step-by-step explanation:

600 = 25x + 50  Subtract 50 from both sides of the equation

550 = 25x  Divide both sides by 25

24 = x

Answer: x = 22

Step-by-step explanation:

We need to use trial and error for this.

20 - 25 seems like a reasonable range to substitute x with.

C(20) = 25(20) + 50

C(20) = 500 + 50

C(20) = 550.

This means that 20 is not the answer. Let's try 21.

C(21) = 25(21) + 50

C(21) = 525 + 50

C(21) = 575.

This means that 21 is also not the answer. let's try 22.

C(22) = 25(22) + 50

C(22) = 550 + 50

C(22) = 600.

This means that 22 is the maximum number of people for a budget of $600.

It will take 96.7 days for the whole US population to get infected.

Given information;

The number of people infected with coronavirus doubles every 3.3 days as following;

1 → 2 →  4 → 8 → 16 → 32 → 64 → . . . . . . . . . . . . → 333,000,000

Let 'x' denotes number of 3.3 days passed the for cases 333,000,000.

⇒ [tex]2^x = 333,000,000[/tex]

For the above equation applying log on both sides. we get;

x(In 2) = In (330,000,000)

x =  In (330,000,000)/(In 2)

x = 28.3

Therefore;

So, total no. of 3.3 days passed = 1 + x

                                                     = 1 + 28.3

                                                     = 29.3

And number of days for 1 to 330,000,000 = 29.3 * 3.3 days

                                                                      = 96.7 days

Hence, it will take 96.7 days to infect the total population in US.

Option (3) is correct. A translation of 3 units down.

What is translation of points?

A point's linear displacement from its starting position is referred to as translation. In an x - y coordinate plane, a point's coordinates are labelled with respect to the origin by first indicating the horizontal position and then the vertical position.

Given: The coordinates of Quadrilateral EFGH and its image, Quadrilateral E'F'G'H', are given below,

E(-5, 5)   ⇒ E'(-5, 2)

F(-3, 4) ⇒ F'(-3, 1)

G(-2, 1) ⇒ G'(-2, -2)

H(-4, 2) ⇒ H'(-4, -1)

From above we can see that the y - coordinate of each point is decrease by 3.

Which is the translation of 3 units down.

Nachelle gets 50 points when signing up: 50+#x=#

Nachelle earns 12.5 points for each visit: 50+12.5x=#

Nachelle need at least 170 points: 50+12.5x=170

Subtract 50 from both sides: 50-50+12.5x=170-50

50-50 cancel out so now your left with 12.5x=170-50

Subtract the 170 and 50: 12.5x=120

Divide 12.5 from both sides: 12.5x÷12.5=120÷12.5

12.5x÷12.5 cancel out so the inequality is now x=120÷12.5

Divide 120 and 12.5: x=9.6

Since there is no such thing as 9.6 visits, round to 10.
