Answer:

H (20) = E

380

Step-by-step explanation:

So, Rana is trying to multiply her hours with her earnings to get the product, that's where the variable E is. H stands for hours, and so you will multiply it by 20 because that's how much she gets per hour.

The variables y and x have a proportional relationship, and y = 15 when x = 3. What is the value of x when y = 4?

Akimi4 [234]

Answer:

$x=\frac{4}{5}=0.8$

Step-by-step explanation:

We have been given that the variables y and x have a proportional relationship, therefore, we can represent the relationship between x and y as: $y=kx$ , where k is proportionality constant.

Let us substitute x=3 and y=15 in above equation to find the value of k.

$15=k*3$

$k=\frac{15}{3}$

$k=5$

Now let us substitute k=5 and y=4 in our proportionality equation to find the corresponding value of x.

$4=5x$

$x=\frac{4}{5}$

$x=0.8$

Therefore, the value of x will be 0.8, when y equals to 4.

Answer:

The y-intercept is - 372 and it means that if the manufacturers do not produce and sell any blenders they will have a loss of $ 372.

Explanation:

The polynomial that represents the function is:

$P(x)=8x+0.3x^2-0.0013x^3-372$

Where the variable, x, represents the number of blenders produced and sold monthly, and P(x) is the monthly profit in dollars obtained for the sale of x blenders.

As for the question, the y-intercept is the point on the graph where the function crosses the y-axis, i.e. where the input of the function is x = 0.

Therefore, the y-intercept is the value of the function for x = 0, P(0), and it is found by substituting 0 for x in the polynomial function, which is shown next:
