Answer:
yes
Step-by-step explanation:
A linear function can have its domain restricted to discrete values. The resulting graph will be of points that would lie on a line.
Yes, a discrete graph can be linear.
Answer:
x = -1/4, y = 5/4.
Step-by-step explanation:
Because of the absolute value equation y = |x - 1| the value of y must be positive.
Solving x - 1 = 3x + 2 :
2x = -3
x = -3/2 and y = -5/2 so x= -3/2 is not a solution.
x - 1 xcan also be negative so we have the equation
- (x - 1) = 3x + 2
1 - x = 3x + 2
-1 = 4x
x = -1/4
y = 1 - - 1/4 = 5/4.
The two pieces are continuous for every
So, our only concern is to make sure that the pieces "glue" continuously at x=7.
To ensure this, we evaluate both pieces at x=7, and impose that the two values are equal.
The first piece evaluates to
The second piece evaluates to
So, we want
We move all terms involving c to the left hand side, and all the numerical constants on the right hand side:
Answer:
25
Step-by-step explanation:
Using the rules of BIDMAS, you first work out the calculation inside the bracket. y-z equals 25-20 which equals 5. then, you work out out the fraction. x=10 so 10/2 equals 5. Then, multiply the value inside the bracket (5) by the outside value(5). This equals 25
