X + 19 ≥ 8.3 <<< your inequality equation
x ≥ 8.3 - 19
x ≥ -10.7 << your solution
hope this helps, God bless!
Answer:
Step-by-step explanation:
y-4x=6
y=6+4x, using this value in 2y-3x=4 gives
2(6+4x)-3x=4
12+8x-3x=4
5x+12=4
5x=-8
x= -8/5= -1.6, making y=6+4x become
y=6+4(-1.6)
y= -0.4, so the solution is the point
(-1.6, -0.4)
Answer:
15.5 seconds.
Step-by-step explanation:
From the time the driver activated the brakes until he stopped, he travelled 76 - 14 = 62 meters.
During this time the car slowed down from 8 m/s to 0 m/s.
Assuming the deceleration was constant during this time we can apply one of the equations of motion for constant acceleration:
s = (u + v)t / 2 where u = initial velocity, v = final velocity, s = distance and t = the time, so:-
62 = (8 + 0)t/ 2
62 = 8t/2
4t = 62
t = 15.5 seconds.
Answer:
-4.5c > 9 will have its inequality symbol reversed
-215 ≤ -52d will have its inequality symbol reversed
Step-by-step explanation:
anytime you are multiplying or dividing an inequality by a negative you must reverse the inequality symbol
