4(3x 5)=-4

Solve for x and show work

Answers

Answer 1
Answer:

Answer:

x = -2 if its 4(3x + 5) = -4

OR

x = 4/3 if its 4(3x - 5) = -4

Step-by-step explanation:

Your missing an plus or minus sign.

4(3x + 5) = -4          / multiply contents of parentheses by 4

12x + 20 = -4          / subtract 20 from both sides

12x = -24                / divide both sides by 12

x = -2

OR

4(3x - 5) = -4          / multiply contents of parentheses by 4

12x - 20 = -4          / add 20 to both sides

12x = 16                / divide both sides by 12

x = 16/12              / simplify

x = 4/3
Answer 2
Answer:

Answer: -2

Step-by-step explanation:

To solve the equation 4(3x + 5) = -4, we need to follow these steps:

Step 1: Distribute the 4 to the terms inside the parentheses.

This gives us 12x + 20 = -4.

Step 2: Subtract 20 from both sides of the equation to isolate the variable term.

We get 12x = -4 - 20, which simplifies to 12x = -24.

Step 3: Divide both sides of the equation by 12 to solve for x.

Dividing both sides by 12 gives us x = -24/12, which simplifies to x = -2.

So, the solution to the equation 4(3x + 5) = -4 is x = -2.

how many elements must a set have if the number of proper subsets of the set 1/2 of the total number of subsets of the set?

Answers

A proper subset of a set A is a subset that is strictly contained in A and excludes at least one member of A. The empty set is also a proper subset of any nonempty set. 
So there is only 1 element that a set must have if the number of proper subsets is 1/2 of the total number of subsets. 
For example: A = { 4 }
Proper subset : {  }     ( 1 )
All subsets: { } , { 4 }   ( 2 )
1 = 1/2 * 2
Answer: 1 element.

Find the range of f(x) = 3x - 5 for the domain {-1.5, 2, 4}A) {-8, 10, -1, -1}
B) {-9.5, 1, 7}
C) {8, 10, 1, 1}
D) {9.5, -1, -7}

Answers

For this case we have the following function:

f (x) = 3x - 5

To find the values of the range of the function, we substitute the values of the domain.

We have then:

For x = -1.5:

f (x) = 3 (-1.5) - 5\nf (x) = -4.5 - 5\nf (x) = -9.5

For x = 2:

f (x) = 3 (2) - 5\nf (x) = 6 - 5\nf (x) = 1

For x = 4:

f (x) = 3 (4) - 5\nf (x) = 12 - 5\nf (x) = 7

Therefore, the values of the range are given by:

{-9.5, 1, 7}

Answer:

the range of f (x) = 3x - 5 for the domain {-1.5, 2, 4} is:

B) {-9.5, 1, 7}
B is the answer

Because A and C could not be since the set have 4 results

D could not be because f(4)=. 12-5=7 not -7
