What is the inverse of the function f(x) = x +3?A. h(x) =1/3 x + 3
B. h(x) = 1/3x – 3
C. h(x) = x – 3
D. h(x) = x + 3

Answers

Answer 1
Answer:

Answer:

Option C is correct that is h(x)=x-3

Step-by-step explanation:

We have been given a function:

f(x)=x=3

\text{let y}=f(x)

y=x+3

x=y-3

Hence,f^(-1)y=y-3

Therefore, f^(-1)x=x-3

Hence, Option C is correct that is h(x)=x-3
Answer 2
Answer: f(x) = x + 3
y = x + 3
x = y - 3

Inverse is h(x) = x - 3

How do I solve: 8 – (m - 3) = 7 – 3m​

Answers

Answer:

m=-2

Step-by-step explanation:

8-(m-3)=7-3m

8-1(m)-1(-3)=7-3m

8-m+3=7-3m

-m+3m+8+3=7-3m+3m

2m+8+3=7

2m+11=7

2m=-4

m=-2

What is the midpoint of AB if A(6,-2) and B(10,4)

Answers

Answer:

(8, 1)

Step-by-step explanation:

Lets say you had 2 points, (x₁, y₁) and (x₂, y₂). The midpoint of these two lines would be:

((x_1+x_2)/(2),(y_1+y_2)/(2))

Lets use (6, -2) for (x₁, y₁) and (10, 4) for (x₂, y₂):

((6+10)/(2),((-2)+4)/(2))=((16)/(2),(2)/(2))=(8,1)

So the midpoint of AB would be (8, 1).

I hope you find my answer helpful.

What is the positive solution of x2 – 36 = 5x?

Answers

The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus: x^2 - 36 = 5x x^2 - 5x - 36 = 0 x^2 + 4x - 9x - 36 = 0 x(x + 4) - 9(x + 4) = 0 (x - 9)(x + 4) = 0 x - 9 = 0 or x + 4 = 0 x = 9 or x = -4 Therefore, the positive solution of x^2 - 36 = 5x? is 9.

short answer is 9 for anyone who wants it.

Yes the full answer is -4, 9 but the question asks for the POSITIVE SOLUTION so the answer is just 9

Story problem that can be solved by finding the sum of 506,211 and 424,809

Answers

Answer:

The sum of bill he has to pay is $931,020.

Step-by-step explanation:

Given : Numbers 506,211 and 424,809

To find : Story problem that can be solved by finding the sum of numbers ?

Solution :

Taking an assumptions to create a story,

Ram buys two things i.e. watch and bag from store.

The cost of watch is $506,211.

The cost of bag is $424,809.

Total bill of ram is given by adding the price of the items.

i.e. T=\$506211+\$424809

Adding the amount,

T=\$931020

Therefore, The sum of bill he has to pay is $931,020.
