Answer:
discriminant is zero (0)
Step-by-step explanation:
Actually, you have a double root here: {6, 6}: "two real, equal roots." That tells us immediately that the value of the discriminant was zero (0).
40/x = 40/x+5 + 2/60
-> i don’t have a sketchbook or calculator at the moment so pls figure out the final answer yourself
Answer:
Step-by-step explanation:
It has to be less than 6 , x+y<6
Now in inequalities that have 7 and 5 in them, 7 represents the cost of first ingredient and 5 the cost of second ingredient.multiply each of that number with quantity of that ingredient and sum both up we get the price of the mixture.
the mixture has to be less than 30 that means that it costs less than 30 but 30 can be the answer as well.
The last answer is 7x + 5y
Answer:
9 games
Step-by-step explanation:
If he purchase 1 game, he spent $12.50. If he purchased 2 games, he spent 2(12.50) = $25.
This means he spent 12.5x for x number of games.
His total spending will be 12.5x + 20. He has $17.50 left on the card from $150.
150 - (12.5x + 20) = 17.5
150 - 12.5x -20 = 17.5
130 - 12.5x = 17.5
-12.5x = 17.5 - 130
-12.5x = -112.5
x = 9
Answer:
161700 ways.
Step-by-step explanation:
The order in which the transistors are chosen is not important. This means that we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
3 transistors from a set of 100. So
So 161700 ways.
