Answer: 30
Step-by-step explanation:
Simple formula is
LCM*GCF=PRODUCT OF 2 NUMBERS
120 * 10 = 40 * x
1200 = 40x
x = 1200/40
x = 30

The domain of a function is the range of values for which the function is defined. Since your function is a graph, look at the minimum and maximum values of X for that graph. The graph is a straight line connecting (3,2) to (7,12). So the legal values of X are every value between 3 and 7. And since the value 3 exactly is acceptable as well as the value 7 being acceptable, then the range is from 3 to 7 inclusive. Now look at the available answers and you'll see that
"3 ≤ x ≤ 7 or x is between 3 and 7, inclusive"
is one of the available choices and it's correct.</span>
Answer:
Step-by-step explanation:
Assuming this is the slope equation
-2 is the slope
x is point x
5 is the y intercept
y is point y
the regular equation it y = mx + b
the slope is negative so it is decreasing aka gooing down
sorryy if this is the wrong answer to your question
I think its 1
Step-by-step explanation:
if it ain't my bad
We will assume that we have a function relating between the time and the temperature. Any point in this function can be expressed as (x,y) where x is the time and y is the temperature (any point is expressed as (time, temperature)).
We have two points given:
<span>At 7 p.m. the temperature is 72 degrees F: First point is (7,72)
</span><span>At 10 p.m. the temperature is 52 degrees F: Second point is (10,52)
The rate of change is simply the slope of this function, this slope can be calculated as:
rate of change = (y2-y1) / (x2-x2)
we have y2= 52, y1= 72, x2= 10 and x1= 7
Substituting in the equation, we can calculate the rate of change as follows:
rate of change = (52-72) / (10-7) = -6.667 degrees/hours
Note: The negative sign indicated a DECREASE in the temperature.</span>
