Consider functions f and g such that composite g of is defined and is one-one. Are f and g both necessarily one-one. Let f : A → B and g : B → C be two functions such that g o f : A ∴ C is defined. We are given that g of : A → C is one-one.
Answer:
C. 50 degrees
Step-by-step explanation:
Because 6x + 5x = 110° and x = 10
5×10 = FEG 50°
Answer:
6x+4y=12
Step-by-step explanation:
when x-intercept is 0
6(0)+4y=12
0+4y=12
divide by 4 both side
y=3
when y-intercept is 0
6x+4(0)=12
6x+0=12
6x=12
divide by 6 both side
x=2
Answer:
Step-by-step explanation:
Original Ratio = New Ratio All these problems are done the same way. Try to conquer the language.
The original ratio = 24 inches wide / 12 inches tall
Shawna's new ratio = you don't know / 2 inches in height (or tall)
Call what you don't know = x
24/12 = x / 2 Cross multiply
12 * x = 24 * 2 Combine the right
12 * x = 48 Divide by 12
12x/12 = 48/12
x = 4
So the new height is 4 inches.
Alice has read 150 pages, you would multiple 200 by .75 (75%). If Nina had read 50% of her book and she read 150, you multiple by 2, and get 300. So Nina has 300 pages in her book.
