Answer:

w=54

Step-by-step explanation:

Answer:

W = 54

Step-by-step explanation:

Angles on a straight line add up to 180

180 - 126 = 54

Answer:

x = 6

Step-by-step explanation:

Based on the two secants intersecting theorem, thus:

(x + 4)*4 = (3 + 5)*5

x*4 + 4*4 = (8)*5

4x + 16 = 40

4x + 16 - 16 = 40 - 16 (subtraction property of equality)

4x = 24

4x/4 = 24/4 (Division property of equality)

x = 6

x = 8 and y = 4

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.

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.

Answer:

Part-to-part ratios provide the relationship between two distinct groups

Step-by-step explanation:

For example, the ratio of men to women is 3 to 5, or the solution contains 3 parts water for every 2 parts alcohol. Part-to-whole ratios provide the relationship between a particular group and the whole populations (including the particular group).

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

Step-by-step explanation:

Expand the factors and compare the coefficients of like terms.

Given

(mx + 2)(3x - 5) ← expand using FOIL

= 3mx² - 5mx + 6x - 10

Compare to 12x² - 14x - 10

For the 2 to be equal, then the coefficients of like terms must be equal.

Compare coefficients of x² terms

3m = 12 ( divide both sides by 3 )

m = 4 → C

Step-by-step explanation:

Answer:

Conclusion:

The rate of change of function 1  = 3

The rate of change of function 2 = 5/3

The initial Value of function 1 = y = 2

The initial Value of function 2 = y = 3

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

The initial Value of function 1 = y = 2

The initial Value of function 2 = y = 3
