Answer:

95 balloons

Step-by-step explanation:

red = 40

green- 40x(3/5) = 24

yellow- 24÷(2/3) =36

36× (1/36) = 1. 1 yellow balloon popped

24× (1×12) = 2. 2 green balloons popped

40×(1/20) =2. 2 red balloons popped

40+24+36= 100

2+2+1=5

100-5 = 95 balloons left for decorations

Step-by-step explanation:

A linear equation can have one or more variables.

The function is given as:

[tex]\mathbf{T = 5.50p + 7f}[/tex]

(a) The constraints when T = 40

Substitute 40 for T in [tex]\mathbf{T = 5.50p + 7f}[/tex]

[tex]\mathbf{5.50p + 7f = 40}[/tex]

The variables in the above equation are p and f

Hence, the constraints are the cost of a package of plain coffee and the cost of a package of flavored coffee

(b) Solve for f

In (a), we have:

[tex]\mathbf{5.50p + 7f = 40}[/tex]

Subtract both sides by 5.50p

[tex]\mathbf{7f = 40 -5.50p }[/tex]

Divide both sides by 7

[tex]\mathbf{f = \frac{40 -5.50p}7 }[/tex]

Hence, the equation of f is:

[tex]\mathbf{f = \frac{40 -5.50p}7 }[/tex]

(c) The maximum number of flavored coffee when she buys 3 packages of plain coffee

In (b), we have:

[tex]\mathbf{f = \frac{40 -5.50p}7 }[/tex]

Substitute 3 for p

[tex]\mathbf{f = \frac{40 -5.50 \times 3}7 }[/tex]

[tex]\mathbf{f = \frac{40 -16.50}7 }[/tex]

[tex]\mathbf{f = \frac{23.5}7 }[/tex]

Divide

[tex]\mathbf{f = 3.36 }[/tex]

Remove the decimal part (do not approximate)

[tex]\mathbf{f = 3 }[/tex]

Hence, the maximum number of packages of flavored coffee she can buy is 3

From the question;

1) Ruby will save $95 after ten weeks

2) The equation for ww weeks is; S = $25 + ($7 x ww)

Total savings after 10 weeks:

Ruby saves $7 per week from her after school job, and she already has $25, so her total savings after 10 weeks can be calculated as follows:

Total savings = Initial savings + (Weekly savings x Number of weeks)

Total savings = $25 + ($7 x 10)

Total savings = $25 + $70

Total savings = $95

So, Ruby would have a total of $95 after 10 weeks of saving.

Expression for the amount of money Ruby would have saved in ww weeks:

Let "S" represent the total savings after ww weeks.

Expression: S = $25 + ($7 x ww)

Answer:

The difference between the two values is -9

The resulting expressions for [tex](f\,\circ\,g)(x)[/tex] and [tex](g\,\circ\,f)(x)[/tex] are [tex]5- 2\cdot x^{2}[/tex] and [tex]-4\cdot x^{2} + 12\cdot x -5[/tex], respectively.

A composition is a operation two functions in which the independent variable of the first function is substituted by the entire second function. In other words, we have the following expressions:

[tex](f\,\circ\,g) (x) = f(g(x))[/tex] (1)

[tex](g\,\circ \,f)(x) = g(f(x))[/tex] (2)

If we know that [tex]f(x) = 2\cdot x - 3[/tex] and [tex]g(x) = 4 - x^{2}[/tex], then we have the following compositions:

[tex](f\,\circ\, g) (x) = 2(4-x^{2})-3[/tex]

[tex](f\,\circ\,g)(x) = 5-2\cdot x^{2}[/tex]

[tex](g \circ f) (x) = 4 - (2\cdot x-3)^{2}[/tex]

[tex](g\,\circ f) (x) = -4\cdot x^{2} +12\cdot x -5[/tex]

The resulting expressions for [tex](f\,\circ\,g)(x)[/tex] and [tex](g\,\circ\,f)(x)[/tex] are [tex]5- 2\cdot x^{2}[/tex] and [tex]-4\cdot x^{2} + 12\cdot x -5[/tex], respectively.

Solution by graphing: (5, 2)

Step-by-step explanation:

y = x - 3  

y = - 3/5x + 5

To solve systems of linear equations graphically, you'll have graph each equation using 2 pairs of points.  

A great starting point is always using its intercepts:

y = x - 3

where the y-intercept is (0, -3).

To find its x-intercept, set y = 0 and solve for the value of x:

y = x - 3

0 = x - 3

Add 3 to both sides:

0 + 3 = x - 3 + 3

3 = x

Therefore, the x-intercept = (3, 0).

y = - 3/5x + 5

where the y-intercept is (0, 5).

Next, you could find a value of x that easily cancels out the fraction given by the slope (m) = -3/5. An input value of x = 5 cancels out the denominator of the slope:

y = - 3/5x + 5

y = - 3/5(5) + 5

y = -3 + 5

y = 2

Therefore, the other point that you could use to plot on the graph is (5, 2).

For y = x - 3, we'll use the line's intercepts: (0, -3) and (3, 0).  

For  y = - 3/5x + 5, we'll use (0, 5) and (5, 2).  

Plotting these points on the graph will give us a solution of (5, 2), as it is the point where both lines intersect. Attached is a screenshot of the graphed lines.

Answer:

x+x refers to x being added

For Eg:

5+5=10

x+x refers to x being multiplied

For Eg:

5*5 = 25

So you can see that the product is greater than sum

Not always though,

For Example take 2+2=4

and 2*2 = 4

Interestingly 2^2 is also equal to 4
