The answer is c

let’s say he rents it for 2 hours,

t= hours, so t=2

20 is the deposit and since t is multiplied by 8,

8(2) + 20

<h3>Hello there!</h3><h3>Answer: c) the hourly rate for renting the bicycle </h3>

The reason why answer choice "c) the hourly rate for renting the bicycle" would be the correct answer because 8 represents the hourly rate of the bike.

A coefficient is a number that that is multiplicative. In other words, it's a number that has a variable next to it, in which makes it change when we know the value of the variable.

8 is right next to "t", in which t represents the amount of hours it was rented for.

What this means is that the number 8 represents the cost of the bike per hour.

The quick computing company discovered that it costs 45$ to produce 2 calculators, 143$ to produce 4 calculators,and 869$ to pro
telo118 [61]
<span>Using the points (2, 45) (4, 143) and (10, 869), we can plug them into the following system of 3 equations using the y = ax^2 + bx + c format:

45 = a(2)^2 + b(2) + c
143 = a(4)^2 + b(4) + c
869 = a(10)^2 + b(10) + c

which simplifies to:

45 = 4a + 2b + c
143 = 16a + 4b + c
869 = 100a + 10b + c

Solving the system, we get a = 9, b = -5, and c = 19. Thus the equation is:

c(x) = 9x^2 - 5x + 19

If you have a TI graphing calculator, you can also enter the points by pressing Stat -> Edit and enter (2, 45) (4, 143) and (10, 869) into it. Go back and calculate the QuadReg of the points from the Calc tab and it will give you the same answer.

Now that we know the function that will produce the price of production for any number of calculators, plug in x = 7 and it will give you the price to produce 7 calculators.

c(x) = 9x^2 - 5x + 19
==> c(7) = 9(7)^2 - 5(7) + 19
==> c(7) = 441 - 35 + 19
==> c(7) = 425

Therefore, it costs $425 to produce 7 calculators.

Hope this helps.

the coordinates of points a and b are (2,4) and (-2,-4) respectively. what is the slope of the line that connects the two points
solmaris [256]

we are given two points as

(2,4) and (-2,-4)

Let's assume

first point as (x1,y1)=(2,4)

so, x1=2 and y1=4

Second  point as (x2,y2)=(-2,-4)

so, x2=-2 and y2=-4

now, we can use slope formula

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug values

m=\frac{-4-4}{-2-2}

now, we can simplify it

m=2

so, slope is 2 ..................Answer
