Determine which statement is true about the graph of a function

Mathematics
1 answer:
Mashcka [7]4 years ago
6 0
The correct answer here is B.

Let's start with the first statement: "The degree of the function is even."  

This statement is true as both ends of the graph are approaching negative infinity and is resembles y=x^2 (an even degree function).

Second Statement: "The leading coefficient is negative."
This is also true has this parabola is faced downwards, meaning it is negative.  Also, a quadratic that has a maximum as its vertex is always going to be a negative function.

A washer and dryer cost $652 combined. The washer cost $48 less than the dryer. What is the cost of the dryer?
Levart [38]

Answer:

The dryer costs $350

Step-by-step explanation:

<u>Step 1:  Make a system of equations</u>

<em>w + d = 652</em>

<em>w = d - 48</em>

<em />

<u>Step 2:  Plug in the know w into the first equation</u>

d - 48 + d = 652

2d - 48 + 48 = 652 + 48

2d / 2 = 700 / 2

<em>d = 350</em>

<em />

Answer:  The dryer costs $350

Y=4x^2+7x vertex form
cricket20 [7]
Use completing the square:

Ex:
y = x^2 +4x  \\  \\ y= x^2 +4x +(\frac{4}{2})^2- (\frac{4}{2})^2 \\  \\ y = (x^2 +4x+4) - 4 \\  \\ y = (x+2)^2 - 4

Now apply to your problem.
First factor out the '4' in front of the 'x^2' term
y = 4(x^2 + \frac{7}{4}x)
Apply completing the square:
y = 4(x^2 + \frac{7}{4}x +(\frac{7/4}{2})^2 -(\frac{7/4}{2})^2) \\  \\ y = 4[(x^2 + \frac{7}{4}x+\frac{49}{64}) - \frac{49}{64} ] \\  \\ y = 4(x + \frac{7}{8})^2 - \frac{49}{16}

The area expression of 6s^2 represents the surface area of a cube with edges of length s. What is the surface area of a cube wit
Romashka [77]
A = 6s²

a) s = 3in, subtitute

A = 6 · 3² = 6 · 9 = 54 (in²)

b) s = 1.5 m, subtitute

A = 6 · 1.5² = 6 · 2.25 = 13.5 (m²)
