If your numbers are 4 1/2 and 2 1/2, then at the end of round 2 brian would have lost 7 points in total
Answer:
y = 2 and y = -5
Step-by-step explanation:
Because the coefficient is not greater than 1, you can simply solve the problem without the quadratic formula.
By using the "x" method, you must figure out what multiplies to give you -10, and adds to give you 3
So, you find your values as 5 and -2. You then set these values equal to zero in terms of Y. As so---- (y+5)=0 and (y-2)=0
Then, you solve out to get your answer! Y is equal to -5 and 2
Answer:
x+y=5
Step-by-step explanation:
y=-x+5
add x to both sides
x+y=5
Let the slower cars speed equal X.
The faster cars speed would be X+5 ( 5 mph faster).
They traveled for 3 hours
Multiply the time of travel by speed to equal the number of miles traveled.
So you have:
3X + 3(X+5) = 267 miles
Simplify the left side:
3X + 3X+15 = 267
Combine like terms:
6x + 15 = 267
Subtract 15 from each side"
6x = 252
Divide each side by 6:
x = 252 / 6
X = 42
The slower car was traveling at 42 mph and the faster car was traveling at 47 mph.
