Answer:

y = 7 +ln(x)/4

Step-by-step explanation:

Maybe your parameterized equation is ...

(x, y) = (e^(4t), t +7)

Using t = y-7, we can substitute for t in the expression for x:

x = e^(4(y -7))

ln(x) = 4(y -7)

ln(x) +28 = 4y

y = 7 +ln(x)/4

Which of the following steps indicates the addition property of equality while solving the equation –1 – 6x = x – 15? Question 4

den301095 [7]

Answer:

B) -1-6 x +15 = x - 15 +15

Step-by-step explanation:

Explanation:-

Given equation is –1 – 6 x = x – 15

By addition property of equality

⇒ - 1 - 6 x + 15 = x - 15 +15

⇒ - 6 x + 14 = x

subtracting 'x' on both sides ,we get

⇒ - 6 x -x +14 =0

⇒ - 7 x +14 =0

⇒ -7 x = - 14

Dividing '-7' on both sides , we get

x = 2

The solution of given equation is x = 2

Let U = {3, 6, 9, 12, 15, 18, 21, 24} and A = {9, 12, 15, 21}. A'

miskamm [114]

Answer:

A¹ = { 3 , 6, 18 , 24}

Step-by-step explanation:

Explanation:-

Universal set

If all the sets under consideration are the subsets of a fixed set 'U' then the set 'U' is called the Universal set.

Given U = {3, 6, 9, 12, 15, 18, 21, 24}

Given A = {9, 12, 15, 21}

Compliment Of A

The Complement of a set A is all the objects that do not belong to set A

The Compliment of A is denoted by A¹

A¹ = U - A

= {3, 6, 9, 12, 15, 18, 21, 24} - {9, 12, 15, 21}

A¹ = { 3 , 6, 18 , 24}
