Answer:
This system has one solution only
Step-by-step explanation:
We have to evaluate the equations shown in the picture you gave
Since the equations differs, they are not the same, this system has only on solution for x and for y.
In fact, if we sum them, we obtain y=0, and then x=2
Answer:
y=-3/4-5
Step-by-step explanation:
plug in ordered pair 1= -3/4(-8)+b
solve for b. b= -5
plug in to y=mx+b
Answer:
0.2952
Step-by-step explanation:
Not enough seats will be available if 23 or 24 people show up.
Required probability = 24C24(0.9005)24 + 24C23(0.9005)23*0.0995 = 0.2952
-1/2 x < -12
Multiply both sides by -1 :
1/2x > 12
x > 12 × 2
x > 24
