Answer:
12
Step-by-step explanation:
A₃ = 3 * 2⁽³⁻¹⁾ = 3 * 2² = 3 * 4 = 12
Answer:
See below
Step-by-step explanation:
I think it’s four less than the quotient of a number cubed and seven, increased by three
I hope you get this right!
Use subtitution method to solve the problem.
First, change y to the value of x in order to find the exact value of x.
x + y = 4
y = 4 - x
Second, subtitute y with 4 - x from the first equation
y = -x² + 2x + 4
4 - x = -x² + 2x + 4
move all terms to the left side
x² - 2x - x + 4 - 4 = 0
x² - 3x = 0
x(x - 3) = 0
x = 0 or x = 3
Third, now we have 2 values of x. Find the value of y for each of x
For x = 0
y = 4 - x
y = 4 - 0
y = 4
For x = 3
y = 4 - x
y = 4 - 3
y = 1
The solution is (0,4) and (3,1). The answer is option b
Answer:
42 minutes
Step-by-step explanation:
70% x T = 98
7T/10 = 98
7T = 980
T = 140 mins
140 - 98
= 42 minutes
Answer:
B
Step-by-step explanation:
(1/3)^-4
=1/[(1/3)^4]
=1/(1/81)
=81
