5^-x +7=2x+4 solution

Mathematics
1 answer:
vodomira [7]3 years ago
4 0

Simplifying

5x + 7 = 2x + 4

Reorder the terms:

7 + 5x = 2x + 4

Reorder the terms:

7 + 5x = 4 + 2x

Solving

7 + 5x = 4 + 2x

Solving for variable 'x'.

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

Add '-2x' to each side of the equation.

7 + 5x + -2x = 4 + 2x + -2x

Combine like terms: 5x + -2x = 3x

7 + 3x = 4 + 2x + -2x

Combine like terms: 2x + -2x = 0

7 + 3x = 4 + 0

7 + 3x = 4

Add '-7' to each side of the equation.

7 + -7 + 3x = 4 + -7

Combine like terms: 7 + -7 = 0

0 + 3x = 4 + -7

3x = 4 + -7

Combine like terms: 4 + -7 = -3

3x = -3

Divide each side by '3'.

x = -1

Simplifying

x = -1

The lengths of the sides of a triangle are in the extended ratio 6 ​: 7 ​: 9. The perimeter of the triangle is 44 cm. What are t
Dimas [21]

Add 6+7+9, which gives 22.

Divide 44 by 22, which is 2.

Multiply the ratio by 2:

(6 : 7 : 9) * 2 = 12 : 14 : 18

The lengths of the sides are 12cm, 14cm, 18cm.

Which polynomial represents the sum below? (14x2 – 14) + (–10x2 – 10x + 10) A. 4x2 – 10x + 24 B. 4x2 – 10x – 4 C. 24x2 – 24x – 1
Gennadij [26K]

Answer:

answer : B

Step-by-step explanation:

(14x2 – 14) + (–10x2 – 10x + 10) = (14x² - 10x²) -10x + (-14+10)

(14x2 – 14) + (–10x2 – 10x + 10) = = 4x² - 10x - 4

answer : B

Y+5=2(x+1) find x and y intercepts
Andrej [43]

The x and the y intercept are x = 1.5 and y = -3

<h3>How to determine the x and the y intercept?</h3>

The linear equation is given as:

y + 5 = 2(x + 1)

Set x to 0 to determine the y-intercept.

So, we have:

y + 5 = 2(0 + 1)

This gives

y + 5 = 2

Evaluate

y = -3

Set y to 0 to determine the x-intercept.

So, we have:

0 + 5 = 2(x + 1)

This gives

5 = 2(x + 1)

Evaluate

x = 1.5

Hence, the x and the y intercept are x = 1.5 and y = -3
