14.578 = 1 x 10 + 4 x 1 + 5/10 + 7/100 + 8/1000 = 10 + 4 + 0.5 + 0.07 + 0.008
I don't answer the grammar but if you asked how many kids in total (not counting duplicate people that signed up for both) then 1073 student registered for the courses
Answer:
3xy-15 thats the simplified form
The equation of a line perpendicular to the line 2x − 5y = 7 is y = (-5/2)x + b
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables or numbers.
Two lines are said to be perpendicular if the product of their slopes is equal to -1.
The slope of the line:
2x - 5y = 7
5y = 2x - 7
y = (2/5)x - 7
The slope of the line 2x - 5y = 7 is 2/5. The slope of the line perpendicular is -5/2
Hence:
The equation of a line perpendicular to the line 2x − 5y = 7 is y = (-5/2)x + b
