Answer:
c)
Step-by-step explanation:
Find the LCM of 5, 6 = 30
P1 = (-7, -9)
P2 = (-2, 4)
ratio = 1/4
x = (-7 + 0.25(-2))/(1 + 0.25)
= (-7 - 0.5) / 1.25
= -7.5/1.25
= -6
y = (-9 + 0.25(4)) / (1 + 0.25)
y = (-9 + 1) / 1.25
y = -8/1.25
y = 6.4
The coordinate sof the point are (-6, 6.4)
Answer:
D
Step-by-step explanation:
substitute t=-3 in the equation
3(-3) squared +5(-3)+6=18
1 lb is equal to 16 oz
so you would do 16*9 which equals 144.
9 lb= 144 oz
Answer:
7.5 days
Step-by-step explanation:
A working = 10 days
AB working = 4 days
AB = 4 --> 10B = 4
/10 /10
B = .4
AB = 3
A(.4) = 3
/.4 /.4
A working alone = 7 .5 days
<em>*pretty much solve for B and then equal AB to the amount of days the worked together before B left, 3 days, then it gives you the amount of time A must work to finish the house alone*</em>
