Answer:
its c
Step-by-step explanation:
Answer:
-21 r^5
Step-by-step explanation:
(7r) (-3r^4)
Multiply the coefficients
7*(-3)
-21
Multiply the variables
r * r^4 = r^(4+1) = r^5
-21 r^5
Answer:
1/2
Step-by-step explanation:
2/3 times 3/4 is 6/12, and 6/12 in simplest form is 1/2.
F(x) = 1.25(38 - x)
Finding the inverse of a function:
y = f(x)
y = 1.25(38 - x)
Solve for x:
y = 1.25(38 - x)
y/1.25 = 38-x
x = 38 - y/1.25
Switch x and y.
y = 38 - x/1.25
f^-1(x) = 38 - x/1.25
Answer: two equations represent the situation are
y = 3x and y = x + 4
Step-by-step explanation:
The smaller number was represented by x and its values on the x coordinate.
The larger number was represented by y and its values on the y coordinate.
The larger number is equal to 3 times a smaller number. This means that
y = 3x
Also, the sum of the smaller number and 4 is the larger number. This means that
y = x + 4
