What are the solutions to the equation ( 5 x − 15 ) 2 = − 100 ?

Answers

Answer 1

Answer:

x = -7

Step-by-step explanation:

( 5 x − 15 ) 2 = − 100

10x - 30 = - 100

10x = -70

x = -7

Answer 2

Answer:

x = -7

Step-by-step explanation:

[tex]\left(5x-15\right)\cdot \:2=-100\\\\\frac{\left(5x-15\right)\cdot \:2}{2}=\frac{-100}{2}\\5x-15=-50\\5x-15+15=-50+15\\5x=-35\\\\\frac{5x}{5}=\frac{-35}{5}\\\\x=-7[/tex]

calculate the state income tax owed on a $50,000 per year salary (answer is not 2500)

Answers

The total tax paid is $2,300 on the yearly salary of $50,000

What tax rate applies to the first $10,000 of salary?

The first $10,000 of the salary would be charged to tax at 3% whereas the next threshold beyond $10,000 up until $50,000, in other words, the difference between the first $10,000 and $50,000, which is $40,000 is taxed at 5%.

The tax on the first $10,000 is computed as shown below:

tax on the first $10,000=$10000*3%

tax on the first $10,000=$300

The tax on the remaining $40,000 is 5% of the amount

The tax on the remaining $40,000=5%*$40,000

The tax on the remaining $40,000=$2,000

In other words, the total tax paid on the $50,000 annual salary is the sum of $300 and the $2000

total tax paid=$300+$2,000

total tax paid=$2,300

HELP ME WITH THIS TWO PROBLEMS
1. When I add 6 to five times my number I get 36. My mystery number is ....

2. When I add 7 to three times my number I get 43. My mystery number is....

Answers

Answer:

1) 6 & 2)12

Step-by-step explanation:

Solve the equations backwards-

1) Subtract 6 from 36, and then divide by 5.

36 = 6 + 5x

(36 - 6)/5 = x

x = 6

2) Subtract 7 from 43, and then divide by 3.

43 = 7 + 3y

(43 - 7)/3 = y

y = 12

the data set represents the total number of tickets each person purchased for a play. 0, 0, 1, 1, 1, 2, 2, 2, 4, 4 what is the median of the data? 1 1.5 2 2.5

Answers

The median of the data 0, 0, 1, 1, 1, 2, 2, 2, 4, 4 is 1.5

There are three measures of central dispersion:

Mean: This is the average of the given data in the distribution.

Median: It is the middle value of the set when the set is either arranged in ascending or descending order.

Mode: This is the value that has the largest occurrence in the distribution.

Given:

0, 0, 1, 1, 1, 2, 2, 2, 4, 4

The are 10 values in the data

So, we have two middle values: 1 and 2

Median = (1 + 2) / 2

= 3/2

= 1.5

Therefore, the median of the data 0, 0, 1, 1, 1, 2, 2, 2, 4, 4 is 1.5

Answer:

x = - 2

Step-by-step explanation:

Given h(x) = 4x - 1 and h(x) = - 9, then equating right sides gives

if a baseball team has lost 50 matches out of the 120 matches played in total, find out their winning percentage?​

Answers

To find the amount of matches won:

120 – 50 = 70

So the baseball team has won 70 matches.

To convert this to a percentage:

(Matches won / Total matches ) x 100

(70/120) x 100 = 58.3% (rounded to 1 decimal place)

The percentage is the indicating hundredth thus the percentage of winning is 58.33%.

What is the percentage?

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

As per the given,

Total matches = 120

Number of lost matches = 50

Number of winning match = 120 - 50 = 70

Winning percentage = (70/120) x 100 = 58.33%

Hence "The percentage is the indicating hundredth thus the percentage of winning is 58.33%".

What is the equation of the line with a slope of 4 and passes through the point (1, -4)?

Answers

Answer:

y=4x-8

Step-by-step explanation:

m=4 (1,-4)

-4=4(1) + c

-4=4+c

-4-4=c

-8=c

y=4x-8

Answer: y = 4x - 8

Step-by-step explanation:

The best way to go about this is to first put the information you know into point-slope form, which is:

[tex]y-y_{1} =m(x-x_{1})[/tex]

[tex]y_{1}[/tex] and [tex]x_{1}[/tex] represent the values of our point (1, -4), so:

[tex]y_{1}=-4[/tex], and [tex]x_{1}=1[/tex].

[tex]m[/tex] represents our slope of 4, so:

[tex]m=4[/tex]

From this, we can plug in our values:

[tex]y-(-4)=4(x-1)[/tex]

A little simplification and distrobution takes us to this:

[tex]y+4=4x-4[/tex]

Then simply subract 4 from both sides to get this:

[tex]y=4x-8[/tex]

An easier way to reason this is to visualize the line in your head and figuring out what the y-intercept is so you can go strait into the [tex]y=mx+b[/tex] form where b is the y-intercept.
