2. The registration at a preschool is $125. Then,

denis23 [38]

The equation of the total cost is y = 475 x + 125, where y is the total cost for x months

a) The rate of change is $475 per month

b) The initial value is $125

c) The independent variable is the number of months (x)

d) The dependent variable is the total cost after each month (y)

Step-by-step explanation:

The given is:

The registration at a preschool is $125
The parents must also pay $475 per month for tuition

Assume that the total cost is y for x months

∵ The registration fee = $125 ⇒ paid once

∵ The parents pay $475 per month for tuition

∵ The number of months is x

∴ The total cost y = 475 x + 125

The equation of the total cost is y = 475 x + 125, where y is the total cost for x months

∵ y = 475 x + 125 is in the form of the linear equation y = m x + b,

m is the slope of the line and b is the y-intercept

∵ The slope of the line m is the rate of change y with respect to x

∴ m = 475

∴ The rate of change is $475 per month

a) The rate of change is $475 per month

∵ b is the initial value of y at x = 0

∴ b = 125

∴ The initial value is $125

b) The initial value is $125

∵ The independent variable is x

∴ The independent variable is the number of months (x)

c) The independent variable is the number of months (x)

∵ The dependent variable is y

∴ The dependent variable is the total cost after each month (y)

d) The dependent variable is the total cost after each month (y)

the equation of the straight line that passes through the point with coordinates of 0,0 and 2,8. do the same for the coordinates

spin [16.1K]

Answer: Equation of a line passes through (0,0) and (2,8): $y=4x$

Equation of a line passes through (0,0) and (4,2): $y=\dfrac{1}{2}x$

Equation of a line passes through (0,0) and (2,10): $y=5x$

Step-by-step explanation:

Equation of a line passes through (a,b) and (c,d) : $(y-b)=\dfrac{d-b}{c-a}(x-a)$

Then, Equation of a line passes through (0,0) and (2,8):

$(y-0)=\dfrac{8-0}{2-0}(x-0)\\\\\Rightarrow\ y=4x$

Equation of a line passes through (0,0) and (4,2):

$(y-0)=\dfrac{2-0}{4-0}(x-0)\\\\\Rightarrow\ y=\dfrac{1}{2}x$

Equation of a line passes through (0,0) and (2,10):

$(y-0)=\dfrac{10-0}{2-0}(x-0)\\\\\Rightarrow\ y=5x$

If you multiply 2 xr you will get the *<br> -radius<br> -circumference<br> -diameter<br> -area

Komok [63]

Answer:

Diameter

Step-by-step explanation:

Variable r stands for radius.

The radius is half of the length within the circle from the two farthest points.

Multiplying this radius will get you the diameter, which is the full length (instead of half) within the circle from the two farthest points.
