Answer:
Option (c) is correct.
is the correct expression
Step-by-step explanation:
Given : Expression and
We have to subtract from
and choose the correct expression from the given options.
Consider the given expressions and
we have to subtract from
Thus, while subtracting we write term after 'from' before.
Therefore, is the correct expression
Also subtracting gives same result.
So, option (c) gives the same result as obtained from given expression.
Answer:
f^-1(x) = (x - 1)/2
Step-by-step explanation:
f(x) = 2x + 1
y = 2x + 1
x = 2y + 1
2y + 1 = x
2y = x - 1
y = (x - 1)/2
f^-1(x) = (x - 1)/2
Answer:
a4 = -12
Step-by-step explanation:
Buy a new car at market value for $15,000. Car depreciates 20% upon transfer of ownership.
Lease a $15,000 car on a 3 year lease. The monthly payment is $199 and all lease payments are required in the lease.
None of these events will impact the net worth of an individual
Answer:
The answer is true.
Step-by-step explanation:
A polar equation describes the relation between r and θ. Here 'r' is the distance from the origin to a point curve. 'θ' is the angle made by a point on a curve, the pole, and the positive x-axis.
So, the statement - Polar equations can describe graphs as functions, even when their equations in the rectangular coordinate system are not functions - is true.
Answer:
The smaller number is 18
Step-by-step explanation:
Let the numbers be and
where x is the smaller number;
.
The sum of the numbers is 100.
The sum of 8 and the larger number is equal to 5 times the smaller number.
Put equation (2) into equation (1).
Answer:
The smaller number is 18.
Step-by-step explanation:
We have given that
The sum of two numbers is 100. The sum of 8 and the larger number is equal to 5 times the smaller number.
Let x and y are two numbers.
Let y is the larger number.
x+y = 100 eq(1)
y+8 = 5x eq(2)
From eq(1), we have
y = 100-x
Putting above eq(3) into eq(2), we have
100-x+8 = 5x
108 = 5x+x
108 = 6x
x = 108/6
x = 18
Hence, the smaller number is 18.
