X=-1 and y=3
To solve this, because y is equal to 2x+5, you can substitute 2x+5 into the bottom equation for y.
You now have 3x - (2x + 5) =-6
This can be solved like a normal equation. Multiply each term in the parenthesis by -1.
3x - 2x - 5 = -6
Subtract 2x from 3x
x - 5 = -6
Add 5 to both sides
x=-1
Now you can solve for y by plugging -1 in for x in either equation. Im going to use the top one.
y= 2(-1)+5
y= -2+5
y=3
You can check your answer by plugging in the values for x and y into both equations and making sure both sides equal each other.
Answer:
Relative maximum
Step-by-step explanation:
10 × 75 = 750 minutes to file 100% of the files. (Approximately 12.5 hours)
= 0.7
70% of these files = 750 × 0.7 = 525 minutes.
Converting 525 minutes into hours, Jan would to take 8.75 hours to file 70% of the files.
Log 5x³-log x²=2
Log A-log B=log A/B
log 100=2 (⇔10²=100)
log (5x³/x²)=log 100
log 5x=log 100
Then:
5x=100
x=100/5
x=20
Answer: x=20.
The center of data is a single number that summarizes the entire data set. The median is the midpoint value of a data set, where the values are arranged in ascending or descending order. The median can be used to find the center of data when the numbers in the data set contain one or more outliers.
