Step-by-step explanation:
(2c+c) + 12 =78
3c + 12 = 78
78 - 12 = 66
66 ÷ 3 = 22
22 + 22 + 22 + 12 = 78
{ C = 22 }
Answer:
6
Step-by-step explanation:

Answer:
6 1/2
Step-by-step explanation:
because we know that for 150 students ther are meals for five days right? now their are only a hundred students and 150 meals, we know that 50+50=100 right? so if we have 100 meals for all of the students that will be enough for 5 days but 50 more meals would mean 6 1/2 days cuss only half of the students will have a meal, their would only be 50 meals for 50 students
Answer:
Vertex is (-4,3)
Step-by-step explanation:
rewrite the problem from y=-2(x+4)^2+3 to y=ax^2+bx+c
y=-2x^2-16x-29
the parabola points are: a=-2 b=-16 c=-29
then divide x= -b/2(a)
x= -(-16)/2(-2)
simplify: x=-4
go back and plug in x=-4 to get y
y=3
Answer is (-4,3)
