2. Wilton drives a taxicab. He charges $40 per hour. One passenger gave Wilton a tip of $30. Write an expression to represent th

ICE Princess25 [194]

Hopefully this is the correct answer! but your expression would be: y=40x+30
and if he drove for 5hrs then you would plug in 5 for your x value so it would be y=40*5+30 and 40*5 is 200.(the star means multiplying) then add 30 to get a total of $230
so the expression is: y=40x+30
and if he drove for 5hrs then he sould make a total of: $230
hopefully that helped and was the right answer :)

A rectangle has length x and width x – 3. The area of the rectangle is 10 square meters. Complete the work to find the dimension

Tamiku [17]

Answer:

Step-by-step explanation:

Area of rectangle = Length × Width

The given rectangle has a length if x meters

The width of the triangle is (x-3) meters

The area of the rectangle is given as 10 square meters.

Area if rectangle = x(x-3) = 10

Multiplying each term in the parentheses,

x^2 -3x = 10

x^2 -3x -10 = 0

This is a quadratic equation

We will look for two numbers such that when they are multiplied, it will give us -10x^2 and when they are added, it will give -3x. It becomes

x^2 + 2x - 5x -10 = 0

x(x+2)-5(x+2) =0

( x + 2)(x-5) = 0

x = -2 or x = 5

The length of the rectangle cannot be negative so the length is 5 meters

Widith = x+3 = 5-3 = 2 meters

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:
