Step-by-step explanation:
To find f(-6), simply substitute -6 for x in -2x²+x-5:

The probability of drawing a red face card from a deck of cards is 3/26
Explanation:
In a deck of cards, there are 6 red-faced cards.
Probability = No. of favourable events / Total no. of events
So, the probability of drawing a red-faced card is 6 out of 52 cards.
Thus, the probability of drawing a red face card from a deck of cards is 6/52 = 3/26.
Answer:
160
Step-by-step explanation:
if girls is 6 and boys is 8
and there are 120 girls
120g= 6g * 20
meaning you multiply 8 by the same thing
160= 8b * 20

Answer:
8:11
Step-by-step explanation:
That is a ratio, but you can further simplify by dividing each side of the ratio by the same numbers. Start with basic ones you know, for example 50 will go into both evenly.
3600/50:4950/50
72:99
Keep dividing each side until you can't make even numbers.
72/9:99/9
8:11
Take the .5 of the 17.5 and convert it to a fractin.
we know .5 is equal to 50% or 1/2
now we have a mixed number

in order to convert it into an improper fraction you need to multiply the whole number by the denominator and then add the numerator all while keeping the denominator constant.

so
