Answer:
$2.25
Step-by-step explanation:
18/8=2.25
Pi = 3.141593
Radius = half diameter
Calculate Circumference = 2 pi r (2*pi*radius)
Calculate Time = Circumference / Speed
Answer:
y = -4x
Step-by-step explanation:
Find the slope (m) and the y-intercept (b) of the line. Thereafter, substitute the value of each into y = mx + b to get the equation of the line.
✔️Find the slope (m) using two points on the line, (-2, 8) and (0, 0):
Slope (m) = change in y/change in x
m = (0 - 8)/(0 - (-2))
m = -8/2
m = -4
✔️Find y-intercept (b):
Y-intercept = 0, this is where the line intercepts the y-axis.
b = 0
✔️Substitute m = -4 and b = 0 into y = mx + b:
y = -4x + 0
y = -4x
You would have to use the matrices option on the calculator, clearly defining your variables. (Also arrange them so that the variables are in the same exact spot in equation equations; i.e. variables on the left side in a certain order and the answer on the right side)
Begin by clicking 2nd--> matrix (its in x⁻¹)--> edit --> [A] --> specify the size to be 3×4
Write out just the coefficient of each variable, all under a single column (for the specific variable).
The answer (or the number on the right side of the equation) would be the last box on the right.
Return back to the home screen with 2nd--> quit (under mode)
Click 2nd--> Matrix--> math --> B: rref( --> 2nd --> matrix--> names--> [A] --> enter.
Click enter to see the solution.
Hope I helped :)
Answer:
y ≤1
Step-by-step explanation:
The range is the output values
It has a max at 1 and can be any value below 1
y ≤1
