Answer:
x = -7
Step-by-step explanation:
( 5 x − 15 ) 2 = − 100
10x - 30 = - 100
10x = -70
x = -7
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]

6. Find the average rate of change of Pete's height from 3 years
old to 5 years old.
Choices:
o 2 inches per year
o 4 inches per year
O 8 inches per year
Answer:
The Answer is "4 inches per year"
Step-by-step explanation:
To find the Average Rate of Change, you use:
[tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]
So when you insert the numbers from the table, you get:
[tex]\frac{45-37}{5-3}[/tex]
After solving the answer you get is 4. So the avg rate of change is 4 inches per year.

Answer:
5(3)^(n-1)
a*b^n
5 is the second value (n-1), so a=5
the amount triples (*3) every minute, so b=3
D, or an = 5(3)^n-1, is correct!
Let’s break this down...
5 is the number of files that we have in the first minute. The 3 triples the 5. Since there is an exponent, the growth is exponential and will always triple the product before it.

Given h(x)=4x-1, solve for x when h(x)=-9
Step-by-step explanation:
h(x) = 4x - 1
given,
h(x) = -9
now,
h(-9) = 4(-9) - 1
→ -36 - 1
→ -37
hope this answer helps you dear, take care!
Answer:
x = - 2
Step-by-step explanation:
Given h(x) = 4x - 1 and h(x) = - 9, then equating right sides gives
4x - 1 = - 9 ( add 1 to both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2

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....
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
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

What is the equation of the line with a slope of 4 and passes through the point (1, -4)?
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.
Tom is stringing up Christmas lights on his house. The first 2 strings of light have the same number of light bulbs. The 3rd string of light has 12 more light bulbs;? 7 than the first 2 strings. There are a total of 88 light bulbs. How many light bulbs are on the first string?
if a baseball team has lost 50 matches out of the 120 matches played in total, find out their winning percentage?
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%".

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