Hugo decided to pay $2 a week to his brother to buy a bicycle. The equation y – 10 = –2(x – 10) models the amount of money he owes for the bike, where x is the number of weeks and y is the amount of money he still needs to pay. How much did the bicycle cost? $ After how many weeks will Hugo finish paying for the bike? weeks

Answers

Answer 1

Answer:

Answer:

bicycle cost is 30

he will finish paying for the bike at 15 weeks

Step-by-step explanation:

-10=-2x+20, x=15

2x=30

2x15=30

Answer 2

Answer:

Answer:

the answers should be

the first one is 30

the second one is 15

Two cupcakes require 2/3 of a cup of icing with one cup of icing. How many cupcakes would you be able to frost?

Answers

To determine how many cupcakes you can frost, you need to find the ratio of cupcakes to icing required. According to the given information:

- Two cupcakes require 2/3 of a cup of icing.
- This means that one cupcake requires (2/3) / 2 = 1/3 cup of icing.

Now, you can calculate how many cupcakes can be frosted with one cup of icing:

Number of cupcakes frosted = (1 cup of icing) / (1/3 cup of icing per cupcake)

Number of cupcakes frosted = (1 cup) / (1/3 cup) = 3 cupcakes

So, with one cup of icing, you would be able to frost 3 cupcakes.

$\textsf{The correct answer is the third one (below the one that you selected).}$

Explanation:

$\sf\n\textsf{In first option, when x = 2, y = 1 and -1. There are two y-values for one x-value}\n\textsf{so this is not a function.}$

$\textsf{In second option, there are infinite y-values for x = 3. So this is also not a}\n\textsf{function.}$

$\sf\n\textsf{In the third option, there are unique y-values for every values of x. Hence this is}\n\textsf{a function. Actually, the function shown here is a cubic function }y=x^3.$

$\textsf{In the last option, x = 1, y = 2, -2. Here also exists two y-values for a single x}\n\textsf{value. So this is also not a function.}$

Y= − 7x y= 4x+22 Solve the system by substitution

Answers

Answer:

x = -2 u got this

Step-by-step explanation:

-7x = 4x + 22

-11x = 22

x = -2

Easy bro

Final answer:

To solve the system of equations by substitution, solve one equation for one variable and substitute the expression into the other equation. In this case, solve the first equation for y, then substitute that value of y into the second equation. Solve for x and substitute the value back into the first equation to find y. The solution to the system of equations is x = -2 and y = 14.

Explanation:

To solve the system of equations by substitution, we need to solve one equation for one variable and substitute that expression into the other equation.

In this case, we can solve the first equation for y:

y = −7x

Now we substitute this value of y into the second equation:

−7x = 4x + 22

Next, we solve this equation for x:

−7x - 4x = 22

-11x = 22

x = -2

Finally, we substitute this value of x back into the first equation to find y:

y = -7(-2)

y = 14

Therefore, the solution to the system of equations is x = -2 and y = 14.

It takes Gary 1 hour to milk all the cows, and it takes Dana 1.5 hours. How long will it take them to do the job together? Please explain all the steps and models/equations used. Thanks so much.

Answers

It takes Gary 1 hour to milk all the cows. 1 hour per job ==> 1 job per hour.

It takes Dana 1.5 hours. 1.5 hour per job ==> 1/1.5 job per hour.

Working together, they can do (1/1 + 1/1.5) job per hour.

To add these fractions, put them over a common denominator:

(1/1 + 1/1.5) = (1.5/1.5 + 1/1.5) = (2.5/1.5) = 5/3 job per hour.

5/3 job per hour ==> 3/5 hour per job.

3/5 hour = 36 minutes.

b - squareroot of 4 is 2and the squareroot of 9 is 3. 5 is between 4 and 9, meaning it must be between 2 and 3. Also a negative so on the left of the 0.

c - sqrt of 1 is 1 and sqrt of 4 is 2. between 1 and 2. closer to 2 (because 3 is closer to 4) than to 1.
