They are mad as easy try it on your own your answer is suppose to be 80
Answer:
A. f and h
Step-by-step explanation:
For a linear function the First Differences of the y-values must be a constant. i.e. if we take the difference between any two consecutive y values or values of f(x) it should be the constant. For this rule to work, x values must change by the same number every time, which is true for all three given functions.
For function f:
The values of f(x) are: 5,8,11,14
We can see the difference in consecutive two values is a constant i.e. 3, so the First Difference is the same. Hence, function f is a linear function.
For function g:
The values of g(x) are: 8,4,16,32
We can see the difference among two consecutive values is not a constant. Since the first differences are not the same, this function is not a linear.
For function h:
The values of h(x) are: 28, 64, 100, 136
We can see the difference among two consecutive values is a constant i.e. 36. Therefore, function h is a linear function.
Hello from MrBillDoesMath
Answer: 12, 9
Discussion:
Let x be the first number and y the second number. The form the problem statement:
x + y = 21
x - y = 3
Add the two equations. This gives:
(x + x ) + ( y-y) = 21 + 3 =>
2x + 0 = 24 =>
x = 12
Since x -y =3, substituting in the value of x gives, 12 - y = 3 so y = 9
Thank you,
Mr. B
Point-slope formula;
y - y1 = m(x - x1) given point(-1, 4) and slope(m) is 4.
y - 4 = 4(x - (-1)
y - 4 = 4x + 4
y = 4x + 4 + 4
y = 4x + 8 << the equation.
hope this helped, God bless!
Answer:
as in the question it is given that 50 people liked both songs 40 liked folk songs and 80 liked none of the song so we can add the number of people
50+40+80
170
Step-by-step explanation:
the people involved in the survey were 170
