Answer: B. 2=3x+10x^2
Step-by-step explanation:
The expression means the quadratic function equation.
B = 10x^2 + 3x -2 = 0
the equation is [-b ±√(b^2 -4ac)]/2a
b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.
Answer:
3.25 +7.25m
Step-by-step explanation:
The cost of membership in Jump Rope Gym can be modeled by ...
total cost = initial fee + m × (monthly fee)
j = 6.50 +17.50m
Likewise, the cost for Run Run Run Gym is ...
r = 9.75 +24.75m
Then the savings by joining the Jump Rope Gym is ...
r -j = (9.75 +24.75m) -(6.50 +17.50m) = 3.25 -7.25m . . . .savings

The answer is A. The probability that you draw hearts than spades is 1/16
If drawing more than one card with replacement:
The probability of drawing a specific card each time is 1/52n
n= the number of draws.
The probability of drawing a specific card each time is 1/13n.
The probability of drawing a specific suit each time is 1/4n.
Since you draw two types of cards,each time you drew is 1/4 so 1/4 times 1/4 is 1/16.
Kind of cofusion right
