The answer is -1/4.
Hope this helps
F(x) = 4x - 1
All you have to do is substitute the values in the domain for x in the function.
f(-1) = 4(-1) - 1
f(-1) = -4 - 1
f(-1) = -5
f(0) = 4(0) - 1
f(0) = -1
f(1) = 4(1) - 1
f(1) = 4 - 1
f(1) = 3
And so on.
Answer:
the two numbers are 16 and -25
Step-by-step explanation:
Let the two numbers be x and y
x+y=-9
x-y=-41
By substitution
y=-9-x
x-(-9-x)=-41
x+9+x=-41
2x=-41-9
2x=-50
x=-25
y=-9-(-25)
y=16
The question is relating Rhonda's distance travelled and time taken
If 45 miles = 3 hours
Then, 1 mile = 3/45 hours
Therefore, it will take Rhonda 1/15 hours to travel 1 mile.
Since the average height is 60 inches and its deviation is 2 inches, one deviation to the right (or higher) is 62 inches (60 + 2). Two deviations is 64 inches, three deviations is 66 inches, and four deviations is 68 inches.
Since the average weight is 100 pounds and its deviation is 5 inches, we repeat the process from finding heights to get to 115 pounds. That takes three deviations.
The MORE deviations away, the more unusual it is. So the height (4 deviations) is more unusual than the weight (3 deviations).
