What is the simplified value of the expression below?
-8*(-3)

Answer: y = (x+2)^2

Aka: B

Step-by-step explanation:

Did it on edge just now !

The equation y = (x + 2)² has a graph that is a parabola with a vertex at

(-2, 0).

Option B is the correct answer.

A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.

The equation of a parabola:

y = a(x-h)^2 + k

We have,

The equation that has a graph that is a parabola with a vertex at (-2, 0) is

y = (x + 2)².

The general equation for a parabola is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

Comparing this general equation to y = (x + 2)²,

We can see that h = -2 and k = 0, which means that the vertex of the parabola is (-2, 0).

Therefore,

The equation y = (x + 2)² has a graph that is a parabola with a vertex at

(-2, 0).

Answer:

X=0

Y=4

Step-by-step explanation:

3x=12-3y

x=4-y

Plug 4-y in for x in the other equation:

2(4-y)+4y=16

8-2y+4y=16

2y=8

y=4

If x=4-y and y=4, x=4-4=0

Answer:

A reflection in the line y = -2, then a translation 2 units right.

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Rigid transformation are transformation that preserves the shape and size of the object. Rotation, reflection, translation are rigid transformation whereas dilation is not a rigid transformation.

Any transformation regarding dilation changes the side length of the object and hence the area.

From the question, only one option is right. The rest options are not right because they involve dilation. The correct option is:

A reflection in the line y = -2, then a translation 2 units right.

Answer:

1. slope formula?

2. (0,6)

3. y= -3x+6

Step-by-step explanation:

because the original formula to make a like is y=mx+b.

just plug the values you have into the equation knowing that m is the slope and b is the y intercept.

the slope would be rise/run which in this case the rise is -6 and the run is 2.

so m= -6/2 = -3

and b = 6 because x is 0 when y is 6 for this graph.

(btw I put -6 as the rise because you are going down 6 units instead of going up)

The company needs to sell 8 units in order for the net income to equal $0

The net income function is given as:

[tex]f(x) = 9x^2 - 54x - 144[/tex]

When the net income is 0, then f(x)  = 0.

So, we have:

[tex]9x^2 - 54x - 144 = 0[/tex]

Divide through by 9

[tex]x^2 - 6x - 16 = 0[/tex]

Expand the above equation

[tex]x^2 +2x- 8x - 16 = 0[/tex]

Factorize the above equation

[tex]x(x +2)- 8(x + 2) = 0[/tex]

Factor out x + 2 in the above equation

[tex](x - 8)(x + 2) = 0[/tex]

Split and solve for x

[tex]x = 8[/tex] or [tex]x =-2[/tex]

The units of product cannot be negative.

So, the value of x is [tex]x = 8[/tex]

Hence, the company needs to sell 8 units

Answer:

21 Books in total

Step-by-step explanation:

If you just want the total number of books, here:

If each student has 3 books, and there are 7 students, we can create the equation: 7 * 3 :because this is showing that 7 people each have 3 books

7 * 3 = 21 so There are 21 books in total

Another we could write it is 3 + 3 + 3 + 3 + 3 + 3 + 3 because there are 7 students with 3 books each. Adding this up would equal 21.

Answer:

At the beginning of the first day there were 75 pistachios in the jar.

Step-by-step explanation:

Given that each day, Robert eats 40% of the pistachios left in his jar at that time, and at the end of the second day, 27 pistachios remain, to determine how many pistachios were in the jar at the start of the first day you must perform the following calculations:

100 - 40 = 60

60 = 27

100 = X

100 x 27/60 = X

2700/60 = X

45 = X

60 = 45

100 = X

100 x 45/60 = X

4500/60 = X

75 = X

Therefore, at the beginning of the first day there were 75 pistachios in the jar.

Answer:

  C

Step-by-step explanation:

The subscript (n-1) is used to indicate the term previous to term (n). In this sequence, each term is 0.5 more than the previous term, so the recursive relation ...

  [tex]a_n=a_{n-1}+0.5[/tex]

is the appropriate one. This matches choice C.

__

Additional comment

Of course, if the next term is 0.5 more than the last, then the previous term is 0.5 less than the present one. The sequence can be described in this "backward" fashion by the recursive relation of choice A. While that does work to describe the sequence, it is usually not the form we desire for a recursive relation.

If Janie cuts half a stick of butter into four equal pieces, one-eighth (1/8) portion of the whole stick of butter is in each of the pieces.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

It is given that Jenny needs 1/2 of a stick of butter for a recipe. She cuts the half stick of butter into four equal pieces.

The portion of the whole stick of butter in each of the pieces is found as,

= (1/2) / 4

=1/8

Thus, if Janie cuts half a stick of butter into four equal pieces, one-eighth (1/8) portion of the whole stick of butter is in each of the pieces.
