You can easily tell if Keisha will finish reading the book by this equation:
y = 325 - 25x
where y is the number of pages left, and x is the number of days. A point slope for has a standard form of y - y1 = m(x - x1). Thus, we arrange it in this manner:
y = 25(13 - x)
Then, substitute x = 10:
y = 25(13 - 10)
y = 75
So, Keisha will not be able to finish the book in 10 days. There are still 75 pages left to read.
Answer:
Associative Property of Addition
Step-by-step explanation:
When you add, you can group the numbers in any combination.
Answer:
Ellipses (special case is called a circle), hyperbolas, parabolas.
Step-by-step explanation:
These are all conic sections.
A conic section is defined by the cross section of a plane and a double-napped cone. There are other special cases called degenerate conics, which are lines and points (occurs when the equation does not follow the usual pattern, however, these are not considered main conics). The main types of conics are: ellipses, hyperbolas, and parabolas.
The illustration below gives more insight into the question.
I hope this helps.
When you solve an inequality, you should always be extra careful to check that you don't multiply it by a negative number - because if you do, then you have to change the sign!
So here, the mistake is in this step:
−9x≥ −36
x ≥ 1.
you should change the sign to ≥
x≤1!
The third one correctly eliminates the y-value from the equation.
