Answers

Answer 1

Answer:

d and g

Step-by-step explanation:

Given

(x - 2)² = - 16 ( take the square root of both sides )

x - 2 = ± [tex]\sqrt{-16}[/tex] = ± [tex]\sqrt{16(-1)}[/tex] = ± 4i ( add 2 to both sides )

x = 2 ± 4i

Thus

x = 2 + 4i → (d)

x = 2 - 4i → (g)

The function shown is reflected across the y-axis to create a new function.

Which is true about the domain and range of each function?

A.Both the domain and range change.
B.Both the range and domain stay the same.
C.The domain stays the same, but the range changes.
D.The range stays the same, but the domain changes​

Answers

Answer: D. The range stays the same, but the domain changes.

Step-by-step explanation: A function can be reflected over or across an axis. When the function is reflected in the y-axis, it means:

g(x) = f(-x)

i.e, the x-values are opposite to the original function.

In the image below, when we reflected the function across the y-axis, the new one will be drawn at the positive x-axis but still at the negative y-axis as shown in red at the second attachment.

Domain of a function is all the values x can assume. Range of a function is all the results the variable y assume.

According to the new graph, y-values didn't change, so Range stays the same. However, x-values changed their signal. Therefore, domain changes.

What is the exact solution to the equation 4^5x=3^(x-2)
list the steps to get the answer

Answers

Answer: x = -0.377

Step-by-step explanation:

We have the equation:

4^(5*x) = 3^(x - 2)

Now we can use the fact that:

Ln(A^x) = x*Ln(A)

Then we can apply Ln(.) to both sides of the equation to get:

Ln(4^(5*x)) = Ln(3^(x - 2))

(5*x)*Ln(4) = (x - 2)*Ln(3)

(5*x)*Ln(4) - x*Ln(3) = -2*Ln(3)

x*(5*Ln(4) - Ln(3)) = -2*Ln(3)

x = -2*Ln(3)/(5*Ln(4) - Ln(3)) = -0.377

Andrew is x years old. Blake is 7 years younger than Andrew. in 5 years time Blake will be twice the age of Carla. how old Carla now in terms of x?

Answers

Answer: Carla is 1/2x years old

Step-by-step explanation:

The present age of Carla in terms of x is (x - 2) / x.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Andrew's age = x

Blake's  age = x - 7

Carla's age = C

After 5 years,

Blake = (x - 7) + 5 = x - 7 + 5 = x - 2

Now,

x - 2 = 2C

C = (x - 2) / 2

Thus,

Carla's age is (x - 2) / 2.
