Answer:

See below in bold.

Step-by-step explanation:

y = -x^2 - 2x - 5

Convert to vertex form:

y = -(x^2 + 2x) - 5

y = - [(x + 1)^2 - 1] - 5

y = -(x + 1)^2  + 1 - 5

y = -(x + 1)^2 - 4

So the vertex of the graph is at (-1 , -4) and it is a maximum because the coefficient of x^2 is negative.

So the range is all values of f(x) up to and including -4.

In interval notation this is (-∞, -4].

Point D is 1/2 of the distance between which two points?
USPshnik [31]

Answer:

B and E

Step-by-step explanation:

B = - 6, D = - 2, E = 2

d(B, D) = - 2-(-6)= - 2 + 6 = 4 units

d(D, E) 2 - (-2) = 2 + 2 = 4

Since, d( B, D) = d( D, E)

Therefore, Point D is 1/2 of the distance between B and E.

if one more freaking person tell me that 120 / 37 is 3 with a decimal I'm going to delete this app because it is just three
lawyer [7]
But 37 is not a factor of 3, in fact it is a prime number so anything that is divisible by it (other than 1) will be a decimal. So, my friend here you have another person on this app telling you that it is not 3 and is in fact 3.2432 (;;;

A cell phone company offers two plans for unlimited calling. The first plan has a monthly charge of $25 and 8.08 per text messag
Alja [10]
The answer is 125 messages.
Firstly the best thing to do is create two different equations.
1. y=25+.08x
2. y=20+.12x
Then you plug into Desmos and see at what point they cross. They cross at (125, 35).
Therefore for 125 text messages would cost 35$ for each plan.
