I need to solve for x

I Need To Solve For X

Answers

Answer 1

Answer:

x=2+√14

Step-by-step explanation:

log(x)+log(x−4)=1

log(x to the second power−4x)=1

Step 1: Solve Logarithm.

log(x2−4x)=1

10log(x2−4x)=101(Take exponent of both sides)

x2−4x=101

x2−4x=10

x2−4x−10=10−10(Subtract 10 from both sides)

x2−4x−10=0

For this equation: a=1, b=-4, c=-10

1x2+−4x+−10=0

x=

−b±√b2−4ac

2a

(Use quadratic formula with a=1, b=-4, c=-10)

x=

−(−4)±√(−4)2−4(1)(−10)

2(1)

x=

4±√56

2

x=2+√14 or x=2−√14

Check answers. (Plug them in to make sure they work.)

x=2+√14(Works in original equation)

x=2−√14(Doesn't work in original equation)

Answer:

x=2+√14

Some please help, select all the intervals where g is increasing

Answers

Answer:

[tex]( - inf, - 3.5) \\ ( - 1, 2.5)[/tex]

These are interval for increasing (doesnt include relative max-min)

Step-by-step explanation:

Increasing means when we input the value of x and we get the increase of y-value.

A bit hard to imagine? You can look at the graph instead. The name already says it all, Increasing Graph. The graph keeps rising and rising till the max and that is increasing.

The decreasing is when the graph decreases to minimum. The graph would face down for decreasing.

Since we only want the increasing. We look at the graph and tell which region does the graph face up and that is the increasing.

Manny bought a brand new car for $29,750. The car depreciates in value by 12% each year. Find the value of the car after 6 years. Round your final answer to the nearest hundredth.

Answers

Answer: $13,846.02

Step-by-step explanation:

The car cost $29,750 when it was first bought.

It will then depreciate at a rate of 12% per year. This means that the value of the car reduces by 12% per year.

To find the value of the car in the 6th year, you can use the compound interest formula:

= Value of car * ( 1 - rate) ^ no. of years

= 29,750 * ( 1 - 12%)⁶

= ‭13,816.021581824‬

= $13,846.02

Answers

Answer:

The value of x is 3

Step-by-step explanation:

Here, we want to find the value of x

to do this, we apply the principle of similar triangles

That would work as follows;

4/x + 5 = 7/(2x + x + 5)

4/x + 5 = 7/3x + 5

4(3x + 5) = 7(x + 5)

12x + 20 = 7x + 35

12x - 7x = 35-20

5x = 15

x = 15/5

x = 3

Work out the percentage change to 2 decimal places when a price of £57.99 is decreased to £49.99.

Answers

Answer:

Percentage change in price = 13.80%

Step-by-step explanation:

Given that:

Original price = £57.99

Decreased price = £49.99

Difference = Original price - Decreased price

Difference = 57.99 - 49.99

Difference = £8.00

Percent change = [tex]\frac{Difference}{Original\ price}100[/tex]

Percent change = [tex]\frac{8.00}{57.99}*100[/tex]

Percent change in price = 13.80%

Hence,

Percentage change = 13.80%

what is the answer to -2(-4x-3)-5x+3=-3

Answers

Answer:

X= -4

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

Distribute the -2 to the parentheses:

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

8x + 6 - 5x + 3 = -3

Add like terms:

3x + 9 = -3

Solve for x:

3x = -12

x = -4

So, the answer is x = -4

What is range?

In statistics, the range of a set of data is the difference between the largest and smallest values. Difference here is specific, the range of a set of data is the result of subtracting the sample maximum and minimum.

According to question, we have to find different range.

The range of data: [tex]52,48,57,47,49,60,59,51[/tex]

[tex]=60-47=13[/tex]

The range of data:[tex]5,9,13,6,4,5,8,12,12,6[/tex]

[tex]=13-4=9[/tex]

The range of data: [tex]97,106,99,97,115,95,108,100[/tex]

[tex]=115-95=20[/tex]

The range of data : [tex]27,13,35,19,71,12,66,47,39[/tex]

[tex]=71-12=59[/tex]

Hence, we can conclude that

The range of data: [tex]52,48,57,47,49,60,59,51[/tex] is [tex]13[/tex]

The range of data:[tex]5,9,13,6,4,5,8,12,12,6[/tex] is [tex]9[/tex]

The range of data:[tex]97,106,99,97,115,95,108,100[/tex] is [tex]20[/tex]
