Use the zeros of the following quadratic to find the x-value of the vertex.y = x2 – 4x – 5
A.5
B.2
C.–2
D.–5

Answers

Answer 1
Answer: 1. y = x^2 - 4x - 5
= x^2 - 4x + 4 - 4 - 5
= (x^2 - 4x + 4) -4 - 5
y = (x-2)^2 - 9 Here, the vertex is at (2, -9) 

2. x = 2 (the vertical line that goes through the vertex) 
3. The graph of this function is called a parabola. To graph a parabola, use 
its vertex (in this case, (2, -9) ) and y-intercept (y = -5). The y-intercept is the constant in the given equation. Use the fact that the vertical line through the vertex is a line of symmetry. Plot the point corresponding to the y-intercept that lies on the other side of the vertical line x = 2. 

4. The graph is translated 2 units to the right and 9 units down.

lois wants to send a box of oranges to a friend by mail. The box of oranges cannot excede a mass of 10 kg. If each orange has a mass of 200g, what is the maximum number she can send?

Answers

Answer:

Maximum number of oranges Lois can send is:

50

Step-by-step explanation:

Lois wants to send a box of oranges to a friend by mail.

The box of oranges cannot exceed a mass of 10 kg.

1 kg=1000 g

10 kg=10000 g

i.e. Mass of box cannot exceed 10000 g

Each orange has a mass of 200 g.

Mass of 50 oranges=50×200 g

                                =10000 g

Hence, maximum number of oranges Lois can send is:

50
easy first cover kilograms into grams 1kg=1000g. resulting in 10,000g dividing that by the weight of the oranges getting 10,000/200=50 so the answer is 50 oranges. (assuming they all weigh the same)

Find the value of x in the equation 4x - 11 = 11.

Answers

Answer:

x = 5.5

Step-by-step explanation:

4x - 11 = 11

4x = 11 + 11

4x = 22

x = 22/4 = 5.5
