10 is B. 9 is 28.8

Step-by-step explanation:

Answer:

x = -1, y = 2

Step-by-step explanation:

plug the first equation into the second to get: 4x-20x=16

simplify: -16x=16

therefore, x = -1, and y = 2

For second one

Vertex is (-3,0)

There is only one x intercepts

Answer:

vertex = (-3, 0)

axis of symmetry: x = -3

one real root at x = -3

Step-by-step explanation:

The vertex is the turning point of the curve (so the maximum point for parabolas that open downwards, and the minimum point for parabolas that open upwards)

The axis of symmetry is the vertical line that goes through the vertex of a parabola.  So this will be the line of the x-value of the vertex.

The roots of a parabola are the points where the curve intersects (or touches) the x-axis.  

First graph

vertex = (3, -4)

axis of symmetry: x = 3

roots: x = 1, 5

Second graph

vertex = (-3, 0)

axis of symmetry: x = -3

one real root at x = -3

Answer:

First term: 6

Common difference:  15/4

Step-by-step explanation:

General form of arithmetic progression:

[tex]a_n=a+(n-1)d[/tex]

(where [tex]a[/tex] is the initial term and [tex]d[/tex] is the common difference between terms)

Question (a)

[tex]\implies a_3=a+(3-1)d=a+2d[/tex]

[tex]\implies a_9=a+(9-1)d=a+8d[/tex]

[tex]\implies a_{25}=a+(25-1)d=a+24d[/tex]

Question (b)

General form of a geometric progression:  [tex]a_n=ar^{n-1}[/tex]

(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)

Therefore, the first three terms of a geometric series are:

[tex]a_1=ar^0=a[/tex]

[tex]a_2=ar^1=ar[/tex]

[tex]a_3=ar^2[/tex]

To find the common ratio:

[tex]r=\dfrac{ar^2}{ar}=\dfrac{ar}{a} \implies \dfrac{a_3}{a_2}=\dfrac{a_2}{a_1}[/tex]

If the 3rd 9th and 25th terms of an arithmetic progression form the first three consecutive terms of a geometric series, then inputting these into the above formula for r:

[tex]\implies \dfrac{a+24d}{a+8d}=\dfrac{a+8d}{a+2d}[/tex]

[tex]\implies (a+24d)(a+2d)=(a+8d)(a+8d)[/tex]

[tex]\implies a^2+26ad+48d^2=a^2+16ad+64d^2[/tex]

[tex]\implies 10ad=16d^2[/tex]

[tex]\implies 10a=16d[/tex]

The 6th and 7th terms of the arithmetic progression are:

[tex]a_6=a+5d[/tex]

[tex]a_7=a+6d[/tex]

If the sum of the 7th and twice the 6th term of the arithmetic progression is 78, then:

[tex]\implies a_7+2(a_6)=78[/tex]

[tex]\implies (a+6d)+2(a+5d)=78[/tex]

[tex]\implies 3a+16d=78[/tex]

Substituting  [tex]10a=16d[/tex]  into  [tex]3a+16d=78[/tex]  and solving for a:

[tex]\implies 3a+10a=78[/tex]

[tex]\implies 13a=78[/tex]

[tex]\implies a=6[/tex]

Substituting [tex]a=6[/tex] into  [tex]3a+16d=78[/tex]  and solving for d:

[tex]\implies 3(6)+16d=78[/tex]

[tex]\implies 16d=60[/tex]

[tex]\implies d=\dfrac{15}{4}[/tex]

Answer:

Step-by-step explanation:

This is called a 'System of equations'.

Say that you have these two expressions, and the unknown is "b".

5b = y

4b+2 = y

Now we can solve two ways; graph it or solve it.

Solving it, we can see that they both equal y, so:

5b=4b+2

move 4b to the left side by subtraction:

(5b-4b) =2

b = 2

let's see what y equals when b = 2

5 * 2 = y

10 = y

Graphing it we see they intersect, or solve at

(2,10) or b=2, y=10

Answer: the cost of the couch is 664 and the cost of the coffe table is 332

Step-by-step explanation:

X is the cost of the coffee table and 2x is the cost of the couch (which is two times more than the coffee table)

2x + x = $996

3x = $996

x = 996/ 3

x = $332 (this is what the coffee table cost)

2x => 2(332)

2x => $664 (the cost of the couch which is two times the cost of the coffee table)

together, $332 + $664 = $996 total

Answer:

-3y -15

Step-by-step explanation:

2y - 5(y-3) = 2y -5y - 15

                = -3y -15

Your welcome, and feel free to comment if you need have any questions!

The simplified value of the expression, 2y−5(y−3) using the Distributive property is 15- 3y.

Given Expression:

2y−5(y−3)

Using Distributive property

[tex]{\text} a *(b+c) = (a *b) + (a*c)[/tex]

So, applying the Distributive property in the expression  5(y - 3) gives

5(y - 3) = 5y - 15

Substituting the value 5y - 15 in 2y−5(y−3) as

2y−5(y−3) = 2y - (5y-15)

                 = 2y - 5y + 15

Now, operating the simplified value is

2y−5(y−3) = 15 - 3y

Thus, the simplified expression is -3y + 15.

Answer:

Distributitive Property

Step-by-step explanation:

The correct justification for the first step in solving the provided equation is that the first step should be distributive Property

Property of equality says that by performing any mathematical operation, of both sides of a expression does not change the original value of the equation.

The equation given in the problem is,

[tex]3(x - 4) + 1 = 12x[/tex]

To solve the above equation, we need to open the brackets of the equation. To do this, we need to use the distributive property of the equality.

This can be done by multiplying the number 3 inside the bracket (x-4). This operation simplify the equation, to solve it further. Therefore,

[tex]3x - 3\times4 + 1 = 12x\\3x - 12 + 1 = 12x[/tex]

Hence, the correct justification for the first step in solving the provided equation is that the first step should be distributive Property.
