on Monday Steven read 9 pages of his new book to finish the first chapter on Tuesday he needs to read double the number of pages

GarryVolchara [31]

Answer=18 pages

Steven read 9 pages on Monday. If he needs to read DOUBLE that amount on Tuesday, then we need to take the number of pages he read on Monday and times it by 2.

9*2=18pages

Steven needs to read 18 pages on Tuesday.

**Remember that Double is the same as 'two times more', or 2x more...

Answer:

1). g(-9) = -81.914

2). Last option

Step-by-step explanation:

1). f(x) = x²

For x = -9

f(-9) = (-9)² = 81

g(x) = $\frac{32}{2x-17}$

g(-9) = $\frac{32}{[2(-9)-17]}$

= $\frac{32}{-35}$

= - $\frac{32}{35}$

(g - f)(-9) = g(-9) - f(-9)

= $-\frac{32}{35}-81$

= $\frac{-32-2835}{35}$

= $-\frac{2867}{35}$

= -81.914

2). The relation is not a function because this function doesn't passes a vertical line test.

Last option will be the answer.
