Answer:
The question is incorrect as it lacks the "x" component. Function f(x) cannot be stated without the x, elseways it couldn't be called "f(x)"
I believe is like this
12 • (2x + 9) • (3 - x)
Step by step solution :
Step 1 :
Equation at the end of step 1 : (3 • (2x + 9) • 4) • (3 - x)
Step 2 :
Equation at the end of step 2 : 12 • (2x + 9) • (3 - x)
Step Three:
Final Result: 12 • (2x + 9) • (3 - x)
They would have 2 because is it 10:1 just double it to be 20:2
Answer:
A.
Gradient: 4
x-intercept: (1,0)
y-intercept: (0,-4)
B.
Gradient: - 3
x-intercept: (-1,0)
y-intercept: (0,-3)
Line y=5x=40
x-intercept: 8
y-intercept: 40
Step-by-step explanation:
y -5x = 40
x-intercept: 0-5x=40
-5x = 40. x = 40/-5
x = -8
y-intercept: y -0 = 40
y = 40
Answer:
The value of k remains constant for table 2
Step-by-step explanation:
Given tables of X values and Y values
To find which tables show the property of direct proportional:
Since Y is direct proportion to X
We write,
y=kx [Equation]
where k is constant of proportion.
Therefore, If the value of k remains constant for any table then, that table shows a direct proportion between y and x values.
For first table :
Now,
when x=1, y=3
Putting into Equation
y=kx
3=k(1)
k=3
Similarly, other calculations are carried out and put it into the form of a table
Note: Figure show tables of given and their respective k values.
Thus, the value of k remains constant for table 2
