Answer:
r=−9.403283,−6.348173,0.751456
Step-by-step explanation:
Let's solve your equation step-by-step.
7(r3+15r2+48r−44)=r+6
7r3+105r2+336r−308=r+6
Step 1: Subtract r+6 from both sides.
7r3+105r2+336r−308−(r+6)=r+6−(r+6)
7r3+105r2+335r−314=0
Step 2: Use cubic formula.
r=−9.403283,−6.348173,0.751456
Answer:
the answer is c for Friday and 6 3/12 hours for them both combined
Step-by-step explanation:
because 3 5/12 is closest to 3 1/2=3 6/12
for fir day and Saturday day combined it would be 6 3/12
because 5/6 is 10/12 and 5/12 + 10/12 is 15/12 which is also 1 3/12
so add 3 +2=5 and then add the fraction 1 3/12 which would be 6 3/12 hours
Answer:
2
Step-by-step explanation:
A function will not have any repeating x values...it can have repeating y values, just not the x ones
{(0,2),(3,8),(-4,-2),(3,-6),(-1,8),(8,3)}
u would have to remove one of the sets of points that has 3 as its x value....so either remove (3,8) or (3,-6)....because with both of them in there, u have repeating x values
