Answer:
This is the same as writing y = (1/2)x + 3
========================================================
Explanation:
Two points on the blue line are (0,3) and (2,4)
To go from the left point to the right, we go up 1 and over to the right 2.
Slope = rise/run = 1/2
Or we can use the slope formula to get the same value
m = (y2-y1)/(x2-x1)
m = (4-3)/(2-0)
m = 1/2
The y intercept is b = 3 because this is the location on the vertical y axis where the blue line crosses. This is the location (0,3).
With m = 1/2 and b = 3, we go from y = mx+b to y = (1/2)x + 3
On a piece of paper, that would look like the equation
Answer:
y is just being multiplyed by -4 :)
Step-by-step explanation:
in other words -4x
Answer:
this
Step-by-step explanation:
Product Rule of Exponents aman = am + n
When multiplying exponential expressions that have the same base, add the exponents.
Example:
Multiply: 4x3 · −6x2
Solution:
Multiply coefficients: 4 · −6 = −24
Use the product rule to multiply variables : x3 · x2 = x3 + 2 = x5
4x3 · −6x2 = −24x5
Answer: ↓↓
Step-by-step explanation:
The original value of the cellphone is $650. The function represents an exponential decay because if it was exponential growth, the function would look like this:
