Part A:
Yes, the data represent a function because there is at least one x-value for every y-value.
Part B:
When x=6 in the input-output table, y=14. When x=6 in the relation f(x)=7x-15, f(x)=7(6)-15=27. <span>The equation has a greater value when x=6.
Part C:</span>
Set f(x) equal to 6 in the equation:
6=7x-15
Solve for x:
7x=21
x=3
<span>x=3 when f(x)=6</span>
Answer:
1 38888888889/50000000000
Step-by-step explanation:
The answer to the first part equation is 1080 ( 3*15*24). The answer to the second question ( 16*20*6) is 1920. Then you divide 1920/ 1080= 1 38888888889/50000000000
Answer:
D is the correct choice
Step-by-step explanation:
To get the y-intercept, we write the equation in the standard form
The standard form is ;
y = mx + b
So we have to rewrite the equation this very form
Thus, we have that;
0.05y = 0.4x + 1.25
we simply isolate the y value
To do this, we divide through by 0.05 and the y-intercept value will be ;
1.25/0.05 = 25
Kevan is 8
katie is 14
Melanie is 16
I think this is the answer.
