-6x+11 = 7-10x show all work

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

collect like terms ( when a negative sign crosses the equality sign it becomes positive and vice versa)

-6x + 10x=7-11

4x=-4

divide both sides by the coefficient of x

4x/4=-4/4

x=-1
Answer 2
Answer: Easy

-6x + 11 = 7 - 10x
Substract 11 from both sides=
-6x = -4 - 10x
Add 10x to both sides
4x = 4
Now divide both sides by the same factor
Answer is x = -1

Someone please help me graph! And I can someone please give me the 5 short answers at the bottom ?

Answers

y = (2/3)x - 1/3
y + 1/3 = (2/3)x
(3/2)*(y+1/3) = x
(3/2)y + 1/2 = x

f^-1(x) = (3/2)x + 1/2
This is the inverse you need to graph.  You can plot this yourself, or use a graphing calculator.

The domain of f^-1(x) is all real numbers
The range of f^-1(x) is all real numbers

For the next 2, just plug in the values and solve:

f(2) = 1
f^-1(-19) = -28

a rainstorm produced a rainfall of 2 inches per hour how many hours would it take to get a rainfall amount of one foot

Answers

There are 12 inches in one foot.  If it rains 2 inches per hour, that means it would take 6 hours to rain 12 inches, or one foot.

6 hours x 2 inches/hour = 12 inches or 1 foot
12 inches in 1 ft. 2 inches per hour. 12 divided by 2 = 6hrs.

A pyramid has a square base with sides 8" and a slant height of 5". Total Area =

Answers

The total area of the pyramid that has 8 inches as its base and 5 inches as its slant hieght is 144 square inches. This is computed by (perimeter of square times slant height) divided by two plus square of the base. It will be equal to (36 x 5) / 2 = 64, which will give us the answer of 144 square inches.

Answer:

144 square units

Find 4 consecutive odd integers whose sum is 232

Answers

4 consecutive odd integers whose sum is 232 are : 55, 57, 59, 61

How to find the sum of consecutive integers?

1 + 2 + 3 + ... + n = (n(n+1))/(2)

Let the first integer be x and x is an odd number.

Let Four consecutive odd integers are;

x, x + 2, x + 4, x + 6

(x) + (x + 2) + (x + 4) + (x + 6) = 232

4x + 12 = 232

4x = 232 - 12

4x = 220

x = 220/4

x = 55

x + 2 = 55 + 2 = 57

x + 4 = 55 + 4 = 59

x + 6 = 55 + 6 = 61

The numbers are : 55, 57, 59, 61

 4 consecutive odd integers...
x, x + 2, x + 4, x + 6

(x) + (x + 2) + (x + 4) + (x + 6) = 232
4x + 12 = 232
4x = 232 - 12
4x = 220
x = 220/4
x = 55

x + 2 = 55 + 2 = 57
x + 4 = 55 + 4 = 59
x + 6 = 55 + 6 = 61

so ur numbers are : 55, 57, 59, 61
