Answer:

18 weeks

Step-by-step explanation:

So, Hugo received $100 for his birthday.

He saved $20 per week. Let x denote the weeks that passed. Therefore:

[tex]y=100+20x[/tex]

This equation represents the total money y Hugo has after x weeks.

The printer cost $460. Thus, set y to $460:

[tex]460=100+20x[/tex]

Solve for x.

Subtract 100 from both sides:

[tex]360=20x[/tex]

Divide both sides by 20:

[tex]x=18[/tex]

Therefore, it took Hugo 18 weeks to save up $460.

Answer:

Domain ( -4,0, 5) Range ( -7, -3, 2, 6)

Step-by-step explanation:

The domain and range of the given relation {(4, -7), (0, 6), (5,-3), (5, 2)}

is:

Domain = { 4, 0, 5, 5 }

Range = { -7, 6, -3, 2 }

Given,

{(4, -7), (0, 6), (5,-3), (5, 2)}

We need to find what is the domain and range of this relation.

A function has an input and an output.

Example: f(x) = x + 4

Now,

x = 1, 2, 3

f(1) = 1 + 4 = 5

f(2) = 2 + 4 = 6

f(3) = 3 + 4 = 7

Here,
Domain = 1, 2, 3

Range = f(1), f(2), f(3) = 5, 6, 7

We can also write it as { (1,5), (2,6), (3,7)}

Find the relation.

(4, -7)

Here,

domain = 4 and range = -7

(0, 6)

domain = 0 and range = 6

(5,-3)

domain = 5 and range = -3

(5, 2)

domain = 5 and range = 2

Find the domain and range of {(4, -7), (0, 6), (5,-3), (5, 2)}.

Domain = { 4, 0, 5, 5 }

Range = { -7, 6, -3, 2 }

Thus the domain and range of the given relation {(4, -7), (0, 6), (5,-3), (5, 2)}

is:

Domain = { 4, 0, 5, 5 }

Range = { -7, 6, -3, 2 }

Step-by-step explanation:

Answer:48

Step-by-step explanation:

If x = 1, then 3*1 = 3 which when modded with 5, we get 3 as a remainder. In other words, 3/5 = 0 remainder 3. We don't use the quotient at all when it comes to modular arithmetic. All we care about is the remainder.

If x = 2, then 3*2 = 6 which leads to remainder 1 when we divide by 5. Therefore, 3x = 1 (mod 5) when x = 2.

If x = 3, then 3*3 = 9 = 4 (mod 5) because 9/5 = 1 remainder 4.

So 3x = 4 (mod 5) when x = 3.

We don't need to check D since x = 3 is a solution and it's smaller than x = 4.

If you wanted to check x = 4, then 3*4 = 12 = 2 (mod 5) because 12/5 yields a remainder of 2.

Answer:

He can buy up to 20 tickets (ie 20 tickets or less)

The equation is 10+3.25x+5 = 80

========================================================

Explanation:

10 = admission cost

3.25 = cost per ticket

x = number of tickets

3.25x = cost from buying x number of tickets

5 = cost of nachos & coke

10+3.25x+5 = total cost of admission, tickets, and food/drink

10+3.25x+5 = 80 since this is the amount he has in his pocket

---------------

Let's solve for x

10+3.25x+5 = 80

3.25x+15 = 80

3.25x = 80-15 .... subtract 15 from both sides

3.25x = 65

x = 65/3.25 ........ divide both sides by 3.25

x = 20

Billy can buy up to 20 tickets (ie 20 tickets or less).

Answer:

1/2x+5/2

Step-by-step explanation:

1. Change f(x) to y

y = 2x – 5

2. Switch x and y.

x = 2y – 5

3. Solve for y by adding 5 to each side and then dividing each

side by 2.

x+5=2y

4. Change y back to f^-1(x)... in other words the inverse

f^-1(x)=(x+5)/2

= 1/2x+5/2

Step-by-step explanation:

y=f-1(x)=1/2(x+5)

explanation: write y equals 2x - 5 and now interchange X and Y it becomes x equals 2y - 5

now solve for y equals F -1 (x) equals 1/2(x + 5)

g(x)= (x + 5) / (2)

is the inverse function of F (x)= 2x - 5

Answer:

you find the gcf/ greatest common factor of both numbers which is 6, so 6 plastic containers

Step-by-step explanation:

If the triangles are similar, that means their side to side ratios will be the same.

For example, we are given the side lengths 6 and 9 to corresponding sides.

Meaning that the side to side ratios are 6:9, or 2:3.

Using this, we can find the missing side length value.

58:x = 2:3

[tex]\frac{58}{x}=\frac{2}{3}[/tex]

[tex]2x=174[/tex]

[tex]x=87[/tex]

The missing side length is 87.

Step-by-step explanation:

To solve this, first, take 22 minutes and divide it by 60 minutes, which is the number of minutes in an hour. Then, add two to the value, and multiply it by six square meters per hour, which is the rate that David can paint the wall. From there, you get 14.2 square meters which he painted in 2 hours and 22 minutes. Divide 14.2 square meters by the length of 11 meters to get 1.290 meters. Since they asked you to round to the nearest meter, you get 1 meter.
