Answer: y = 8*x + 5
Step-by-step explanation:
Here we have the points (1, 13), (2, 21), (3, 29), (4, 37)
You can see that the x-component always increases by one unit, while the y-component always increases by 8 units.
Then we can conclude that this is a linear relationship.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Here we can use the fact that our line passes through the points (1, 13) and (2, 21)
Then the slope of our line is:
a = (21 - 13)/(2 - 1) = 8
Then:
y = 8*x + b
To find the value of b, we can use again the fact that our line passes through the point (1, 13)
This means that when x = 1, the value of y is 13, if we replace that in the equation we get:
13 = 8*1 + b
13 = 8 + b
13 - 8 = b
5 = b
Then:
y = 8*x + 5
This means the amount charged for x hours, is:
y = 8*x + 5

Step-by-step explanation: use the values of a, b, and c to find the discriminant. give me brainliestt
Answer: D = -8
Step-by-step explanation:
Ohh okk so the discriminant basically helps find the number of solutions to a quadratic equation
If D(discriminant) is:
< 0 there are no solutions
= 0 there is one solution
> 0 there are two solutions
The discriminant is found using
b^2 - 4ac
Here a = 3
b = -4
c = 2
(-4)^2 - 4(3)(2)
16 - 24
-8

okay, so you've got your zeros right here actually. it's very simple, so I'll give you the reader's digest: SET THEM ALL TO ZERO
x-1=0 add your one, so that's x=1
x+3=0, subtract your 3, so that's x= -3
the last one is tricky: 2x+1=0, 2x= -1, but you can go further. divide your two, and you're left with x= -1/2

every 3 years the resale of a refrigerator decreases by 100 dollars.
its basically the rate that the price goes down for resale value of a refrigerator
Step-by-step explanation:
Let's take the points displayed on this graph:
(300, 3) (200, 6) and (100, 9).
Our first value in the points represents the amount of money for the resale value of a refrigerator, and the second value represents the number of years after the original purchase. So, as we can see, as the years increase, the value goes down $100 dollars every three years.
3 years after original purchase: $300
Increase years by three, value goes down by $100
6 years after original purchase: $200
The rate of change in this situation means that for every resale three years after the original purchase, the value will decrease by $100.
