Answer:
(-5,-13)
Step-by-step explanation:
Find the vertex of the parabola y=1/5x^2+2x−8.
In this equation a=15 and b = 2.
x= -2/2(1/5) = -2/2/5 = -2/1 * 5/2 = -5
Substitute −5 into the equation y=1/5x^2+2x−8
y=1/5(−5)^2+2(−5)−8
y=5−10−8
y=−13
The vertex is (−5 , −13)
Answer:
=6x+3y
Step-by-step explanation:
3X+3(X+Y)
Distribute:
=3X+(3)(X)+(3)(Y)
=3X+3X+3Y
Combine Like Terms:
=3x+3x+3y
=(3x+3x)+(3y)
=6x+3y

Answer:
The heaviest baby have to gain to reach a healthy level by 42 ounces.
Step-by-step explanation:
It is said that the 500-gram babies are going to have to make four times their weight [to reach a healthy level].
So, the healthy level of weight is (500 × 4) = 2000 gm i.e. 2 kg.
Now, 1 kg is equivalent to 35.274 ounces.
So, 2 kg will be equivalent to (35.274 × 2) = 70.548 ounces.
So, the heaviest baby with weight 28.6 ounces have to gain weight to reach a healthy level by (70.548 - 28.6) = 41.948 ounces ≈ 42 ounces. (Answer)
