For #6
x + y = -10
x - y = 2
First solve for y in one of the equations
x - y = 2
-y = 2 - x
y = -2 + x
y = x - 2
Now substitute into one of the equations and solve for x
x + y = -10
x + x - 2 = -10
2x - 2 = -10
2x = -8
x = -4
Answer:
Step-by-step explanation:
The new brakes decrease the probability that a vehicle will collide with another vehicle. Because the anti-lock brakes cut the time it takes a car to stop by 50%, then total collision will be reduced.
But also give drivers an incentive to drive faster, which could potentially increase the number of car accidents.
Because drivers know that the new brakes cut the time it takes to stop and if they drive faster than before, maybe the new brakes won´t be able to reduce accidents and maybe collisions will increase.
1+1= 2
Big brain >:3 Ty for the points tho ^^
Answer:
2x*x
2x*-5
1*x
1*-5
2x²-10x+x-10 add numbers that have similar variables
-2x²-10x+x-10
=[-2x²-9x-10]
At least 4
10% of 12 is 1.2
So 30% is 3.6
And 1% 0.12
So 2% is 0.24
Plus 3.6 onto 0.24 and you get 3.84
