Answer:
Step-by-step explanation:
Rate of change is another term for the slope.
rate of change = slope = (change in y)/(change in x)
<u>Function A:</u>
y = mx + b (m = slope)
y = 4x - 3
Function A has a slope of 4.
The rate of change for function A is 4.
<u>Function B:</u>
Take two points.
(-1, 0) and (1, 4)
slope = (y2 - y1)/(x2 - x1)
slope = (4 -0)/(1 - -1)
slope = 4/2 = 2
The rate of change for function B is 2.
Answer:
A=Pe^rt
P= princible (1300)
e= (2.71828)- function on a graphing calculator
r = interest rate (.05 or 5%)
t = time (10 years)
A = 1300e^.05(10)
A = 1300e^.5
A = 2143.337652
A = 2143
Answer:
$3.50 + 3·$4.50
Step-by-step explanation:
The total amount of any purchase is computed as the sum of products of quantity and price.
_____
In some instances is is helpful to keep the units (dollars) with the numbers they apply to. Most times, the units will be left off, and you're expected to make sure they work out properly some other way.
9 + 60 -42x
9+60 = 69
= 69- 42x
That the equation could be combined into like terms
