6x - 5 = 6x + 5 what is x?

Mathematics
1 answer:
OlgaM077 [116]3 years ago
3 0

Answer:

This equation does not have a solution.

If you subtract 5 from both sides of the equation, you will get 6x-10 = 6x. Then if you subtract 6x from both sides, you will end up with -10 = 0 which is untrue. Therefore, the equation 6x-5 = 6x+5 has no solution.

Mademuasel [1]

The equation that models the data on pandas is FV = 25(1.066)^t.

<h3>What models the data?
</h3>

The formula for calculating future value of the pandas is:

FV = P (1 + r) ^n

  • FV = Future value
  • P = Present value
  • R = annual population growth
  • N = number of years

FV = 25(1.066)^t

Ivory created a scaled copy of rectangle A.
9966 [12]

The scale factor that Ivory used to create their scaled copy is;

<u><em>Scale is 1 interval on graph represents 4 units of the rectangle. This is 1:4 ratio.</em></u>

  • From the given image, we can see that the y-axis of the rectangle has 3 intervals while the x-axis has 1 intervals

  • Now, from the image, we are told that the area of the scaled copy is 48 square units.

What this means is that the area of the triangle she is trying to represent with that graph is 48 square units.

  • Now, if one interval of the graph is x-units, then it means;

length; y-axis = 3x units

width; x-axis = x units

  • Area of a rectangle is given by;

Area = Length × width

Thus;

3x * x = 48

3x² = 48

x² = 48/3

x² = 16

x = √16

x = 4

<em>Thus, 1 interval on the graph represents 4 units of the rectangle.</em>

Solve by completing the square​
erastovalidia [21]

Answer:

Your answers would be:

x = 10 and x = -8

Step-by-step explanation:

Solve for the zeros:

x² - 2x - 78 = 2

Subtract both sides by 2.

x² - 2x - 80 = 0

Use the quadratic formula: x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

a = 1

b = -2

c = -80

Plug in and solve:

x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-80)}}{2(1)}\\\\x=\frac{2\pm\sqrt{(-2)^2-4(1)(-80)}}{2(1)}\\\\x=\frac{2\pm\sqrt{4-4(-80)}}{2(1)}\\\\x=\frac{2\pm\sqrt{4+320}}{2(1)}\\\\x=\frac{2\pm\sqrt{324}}{2(1)}\\\\x=\frac{2\pm18}{2}\\

Solve for +:

x=\frac{2+18}{2}\\\\x=\frac{20}{2}\\\\x=10

Solve for -:

x=\frac{2-18}{2}\\\\x=\frac{-16}{2}\\\\x=-8

A rectangular kitchen is twice as long as it is wide, and it’s perimeter is 84 feet. Find the dimensions of the kitchen
Stells [14]
So since the kitchens long is wide x 2 if you add the 2 longs it makes a wide so you end up with 3 wides technically. So you divide 84 by 3 and u get 28 so make your 2 wides 28. Then u divide 28 by 2 to get 14 so your longs are 14 and your wides are 28 if u add it all together it’s 84.
