Mathematics

Art [367]2 years ago

Answer:

Simplifying

(-4x + -2) + -1(13x + 1) = 0

Reorder the terms:

(-2 + -4x) + -1(13x + 1) = 0

Remove parenthesis around (-2 + -4x)

-2 + -4x + -1(13x + 1) = 0

Reorder the terms:

-2 + -4x + -1(1 + 13x) = 0

-2 + -4x + (1 * -1 + 13x * -1) = 0

-2 + -4x + (-1 + -13x) = 0

Reorder the terms:

-2 + -1 + -4x + -13x = 0

Combine like terms: -2 + -1 = -3

-3 + -4x + -13x = 0

Combine like terms: -4x + -13x = -17x

-3 + -17x = 0

Solving

-3 + -17x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + -17x = 0 + 3

Combine like terms: -3 + 3 = 0

0 + -17x = 0 + 3

-17x = 0 + 3

Combine like terms: 0 + 3 = 3

-17x = 3

Divide each side by '-17'.

x = -0.1764705882

Simplifying

x = -0.1764705882

Answer:

x = -3/17

Step-by-step explanation:

<u>Step 1:  Distribute the minus sign</u>

(-4x - 2) - (13x + 1)

-4x - 2 - 13x - 1

<u>Step 2:  Combine like terms</u>

-4x - 2 - 13x - 1

-17x - 3

<u>Step 3:  Solve for x</u>

-17x - 3 = 0

-17x - 3 + 3 = 0 + 3

-17x / -17 = 3 / -17

x = -3/17

Answer:  x = -3/17

Solve over the set of real numbers for the equation below x-2=√2x-1
Anon25 [30]

The set of real numbers for the equation x – 2 = √(2x – 1) will be 5.

<h3>What is the solution of the equation?</h3>

The solution of the equation means the value of the unknown or variable.

The equation is given below.

x – 2 = √(2x – 1)

Square on both side, then we have

               (x – 2)² = 2x – 1

         x² – 4x + 4 = 2x – 1

         x² – 6x + 5 = 0

   x² – 5x – x + 5 = 0

x(x – 5) – 1(x – 5) = 0

       (x – 5)(x – 1) = 0

                         x = 1, 5

The set of real numbers for the equation x – 2 = √(2x – 1) will be 5.

More about the solution of the equation link is given below.

CHOOSE TO ANSWER EITHER QUESTION:
Ugo [173]

Answer:

First one: C. Second One:C.

Step-by-step explanation:

Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years?

a) $13,935.76

b) $12,874.57

c) $13,792.99

To solve this this is an exponential function. The price started at $23,000 and depreciates at 12% so the equation is f(x) = (23,0000)(1-0.12)^4. When calculated results with 13792.99328 which is C.

A rare coin is currently worth $450. The value of the coin increases 4% each year. Determine the value of the coin after 7 years.

a) $613.98

b) $546.78

c) $592.17

To solve this this is also an exponential function. The price started at $450 and  the coin increases 4% each year so the equation is f(x) = (450)(1+0.04)^7. When calculated results with 592.169300656 which is c.

PtichkaEL [24]
Butter pecan: 25
Vanilla: 35
Chocolate: 50

The dotted line between 20 and 30 (butter pecan) will be nothing more than anything including 5. In this case, it is 25 counting up to 30.
The solid lines directly leading to a number will be that number, for instance, chocolate is 50.
