Answer 2

Answer:

1.2

Step-by-step explanation:

Add the common variables, -y, 4y, and 7y, to get 10y. Then add the regular numbers 2, 6, 4, to get 12. I think youre trying to get y so it would be 1.2       (Sorry if its wrong)

Annabelle is working two summer jobs, making $10 per hour babysitting and making $20 per hour lifeguarding. In a given week, she can work no more than 19 total hours and must earn no less than $290. If Annabelle worked 3 hours babysitting, determine the minimum number of whole hours lifeguarding that she must work to meet her requirements. If there are no possible solutions, submit an empty answer.

Answers

Answer:

she would need to work at least 13 hours lifeguarding to get to the 290 her with the of working an extra 3 hours  

Step-by-step explanation:

subtract the 30 dollars from babysitting from the 290 needed you 260 then divide it by 20

The minimum number of whole hours lifeguarding that she must work to meet her requirements will be 14 hours.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Annabelle is working two summer jobs, making $10 per hour babysitting and making $20 per hour lifeguarding.

In a given week, she can work no more than 19 total hours and must earn no less than $290.

Now,

Let x represents the number of hour for babysitting, and 'y' represents the number of hours for lifeguarding.

Since, In a given week, she can work no more than 19 total hours and must earn no less than $290.

Hence, We can formulate;

⇒ x + y < 19

And, 10x + 20y > 290

So, For Annabelle worked 3 hours babysitting, the minimum number of whole hours lifeguarding is,

⇒ 3 + y < 19

⇒ y < 16

And, 10x + 20y > 290

⇒ 30 + 20y > 290

⇒20y > 290 - 30

⇒ 20y > 260

⇒ y > 13

Thus, The possible value of y = 14, 15

So, The minimum number of whole hours lifeguarding that she must work to meet her requirements will be 14 hours.

For what value of the constant a does the system of equations below have infinitely many solutions?

Answers

Answer:

1)  Try a = 23/2. With this value, equation 1 multiplied by 2 is exactly the same as equation 2.

2) Try dividing 2005/3 + 2005/4 - 2005/6. Ignore the fractional parts.

3) If you are allowed to repeat the letters, then you should have: 3^3 = 27

Answer:

a = 8

Step-by-step explanation:

For the 2 equations to have infinite solutions we require the solution to be in the form

0 = 0

Given

2x + 5y = - 8 → (1)

6x = 16 + a - 15y ( add 15y to both sides )

6x + 15y = 16 + a → (2)

Multiply (1) by - 3

- 6x - 15y = - 24 → (3)

Adding (2) and (3) term by term gives

0 + 0 = 16 + a - 24

For the right side to be zero , then

16 + a =  24 ( subtract 16 from both sides )

a = 8

Answer:

Conclusion:

The rate of change of function 1  = 3

The rate of change of function 2 = 5/3

Hence, function 1 has a greater rate of change

The initial Value of function 1 = y = 2

The initial Value of function 2 = y = 3

Hence, function 2 has a greater initial value.

Step-by-step explanation:

Function 1)

Determining rate of change for function 1:

x        1         2         3         4

y       5        8          11        14

Finding the rate of change or slope using the formula

Rate of change = m = [y₂-y₁] / [x₂-x₁]

Taking any two points, let say (1, 5) and (2, 8)

Rate of change = m = [8-5] / [2-1]

                                 = 3/1

                                  = 3

Therefor, the rate of change of function 1 = m = 3

using point-slope form to determine the function equation

y-y₁ = m (x-x₁)

where m is the rate of change or slope

substititng m = 3 and the point (1, 5)

y - 5 = 3(x - 1)

y - 5 = 3x-3

y = 3x-3+5

y = 3x + 2

Thus, equation of function 1 will be:

y = 3x + 2

Determining Initial Value for Function 1:

substituting x = 0 in the equation to determine the initial value

y = 3(0)+2

y = 0+2

y = 2

Therefore, the initial Value of function 1 will be: y = 2

Function 2)

Determining the rate of change for function 2:

Given the function 2

[tex]y\:=\:\frac{5}{3}x+3[/tex]

comparing with the slope-intercept form of a linear function

y = mx+b     where m is the rate of change

so the rate of change of function 2 = m = 5/3

Determining Initial Value for Function 2:

substituting x = 0 in the equation to determine the initial value

[tex]y\:=\:\frac{5}{3}x+3[/tex]

[tex]y\:=\:\frac{5}{3}\left(0\right)+3[/tex]

[tex]y = 0+3[/tex]

[tex]y = 3[/tex]

Therefore, the initial Value of function 2 will be: y = 3

Conclusion:

The rate of change of function 1  = 3

The rate of change of function 2 = 5/3

Hence, function 1 has a greater rate of change

The initial Value of function 1 = y = 2

The initial Value of function 2 = y = 3

Hence, function 2 has a greater initial value.
