Answer:
A. (a,0)
D. (a/2, b/2)
Step-by-step explanation:
Let's assume a and b means x and y coordinate if the x and y axes.
So the coordinates are now (0,0) ,(x,y) , (2x,0)
So all point from 0 to 2x lies on the sides of triangle
And all points from 0 to y lies on the
sides of the trianglee.
So we have three. Equation of the triangle .
One is x= y
So (a/2, b/2) is correct.
Second is 2x = 0y
So (a,0) is correct.
Answer:
a) linear. Cost per minute is a constant.
b) f(x) = 40 -0.15x
d) f(100) = 25. The remaining value is $25 after using 100 minutes.
Step-by-step explanation:
a) Since the cost per minute is a constant, the remaining dollar value of the phone decreases by the same amount for each minute used. The cost as a function of minutes used is a linear function with a constant rate of change.
__
b) The value starts at $40 and decreases by $0.15 for each increment of x (minutes used). The function can be written as ...
f(x) = 40 -0.15x
__
d) Put 100 where x is in the function definition and do the arithmetic.
f(100) = 40 -0.15×100 = 40 -15
f(100) = 25
According to the variable and function definitions, x=100 means 100 minutes have been used; f(x) = 25 means the remaining value of the phone is 25 dollars.
f(100) = 25 means the phone's remaining value is $25 when 100 minutes have been used.
Yes it is a solution plug in 2 for x so it would be y=4(2) which would be y=8 and then u just plug in 8 for y and 2 for x and add 6
Answer:
f we are talking about months of births its qualitative, if numbers such as 11, 10, 5, representing days or months or years is involved as data then it is quantitative.
Step-by-step explanation:
Answer:
Technically not on a graph but on a table yes it matter but here if I were you I would do (2,2) and (-1,-4)
Step-by-step explanation: y=mx+b
(2,2) and (-1,-4) 2=2(2)+b Answer is: y=2x+(-2)
x1 y1 x2 y2 2=4+b
-4-2=-6 -2=b
-1-2=-3 y-intercept
m=2
slope
