Answer:

Infinitely many solutions (the lines are identical)

Step-by-step explanation:

Let's start by getting each equation into slope intercept form (y=mx+b)

-14x-14y=28

-14x-28=14y

-x-2=y

and

7x+7y= -14

7x+14= -7y

-x-2=y

We can see that these two lines are identical which means that there are an infinite amount of answers

Answer:

Step-by-step explanation:

x + 2y = 8

x - y = 2

x + 2y = 8

-x + y = -2

3y = 6

y = 2

x - 2 = 2

x = 4

a: 2×2+7×+6ft 2

house: 58×28= 1,624

a: 1624 ft 2

Answer:

x = 1 or -5/2

Step-by-step explanation:

-2x^2 - 3x + 5 = 0

multiply all through by -1

2x^2 + 3x - 5 = 0

....... 2x^2 × 5 = 10x^2 = +5x × -2x

(2x^2 + 5x)-(2x - 5) = 0

x(2x + 5) - 1(2x + 5) = 0

x - 1 = 0 or 2x + 5 = 0

x = 1 or 2x = - 5

x = 1 or -5/2

Answer: D

Step-by-step explanation:

Fill in the x's with -2 for the first time to get one answer then go back and fill in 4 for the second answer.

g(-2)= 10

g(4)=-8

Proving g(-2) is greater than g(4).

Answer.

Step-by-step explanation:

Given = sum of two exterior angle of a triangle is 272 .

rule of triangle is that each and every angle which are outside a triangle is 360.

so, 272 + x = 360

x = 360 - 272

x = 88

Answer:

The answer is 80.5!

Step-by-step explanation:

The reason to the answer is because volume of a cuboid is l×B×H

(Substitute the values)  L = 2 , B = 3.5 , H = 11.5

2 × 3.5 × 11.5

Therefore, when we multiply these numbers we get, the answer 80.5!

Answer:

[tex]a = \{1,4,9,16,25,36,49,64,81,100\}[/tex]

Step-by-step explanation:

Given

[tex]ax^2 - 64[/tex]

Required

Determine possible values of a

For the expression to be a difference of two squares, then a must be a perfect square between 1 and 100 (inclusive).

Let [tex]a = k^2[/tex] where [tex]k \ge 1[/tex]

When k = 1

[tex]a = 1^2 = 1[/tex]

k = 2

[tex]a = 2^2 = 4[/tex]

k=3

[tex]a = 3^2 = 9[/tex]

It goes on until k = 10

[tex]a = 10^2 = 100[/tex]

So, the possible values of a are:

[tex]a = \{1,4,9,16,25,36,49,64,81,100\}[/tex]

Answer:

Geometric

Step-by-step explanation:

The given sequence is; 39, 156, 468, and 936 Geometric sequence.

Three parameters differentiate between which geometric sequence we're talking about. The first parameter is the initial value of the sequence. The second parameter is the quantity by which we multiply the previous term to get the next term. And the third parameter is the length of the sequence. It can be finite or infinite.

Consider that the initial term of a geometric sequence is a and the term by which we multiply the previous term to get the next term is r.

Thus, the nth term of such sequence would be;  [tex]T_n = ar^{n-1}[/tex]

We have been given that the sequence is; 39, 156, 468, 936

Hence, the given sequence is; 39, 156, 468, and 936 Geometric sequence.

179 pregunta 43/24

Answer: 24

Step-by-step explanation:

Because if you do 4.80 times 5 you’ll get 24 because each orange cost $4.80

Answer:

the cost of 5 oranges would be $2.00

Step-by-step explanation:

To solve this we need to find the unit rate and when we do this we can solve this problem.  To find that we need to divide 4.80 by 12 once we do that we just have to multiply that number by 5 to get our answer, when you divide you'll get 0.4 and then multiply that by 5 and you'll get $2.00.

Answer:

x > 4; r–1(x) = 4 + StartRoot StartFraction 11 Over x EndFraction EndRoot

Step-by-step explanation:

We are given that

[tex]r(x)=\frac{11}{(x-4)^2}[/tex]

We have to find the domain of restriction on r(x) and corresponding inverse function.

Let

[tex]y=r(x)=\frac{11}{(x-4)^2}[/tex]

[tex](x-4)^2=\frac{11}{y}[/tex]

[tex]x-4=\sqrt{\frac{11}{y}}[/tex]

[tex]x=\sqrt{\frac{11}{y}}+4[/tex]

[tex]r^{-1}(y)=\sqrt{\frac{11}{y}}+4[/tex]

Now, replace x by y and y by x then, we get

[tex]r^{-1}(x)=\sqrt{\frac{11}{x}}+4[/tex]

The function is not defined at x=4

But,

The inverse function defines for all positive real values.

Therefore, domain of r(x)=x>4 and inverse function

[tex]r^{-1}(x)=\sqrt{\frac{11}{x}}+4[/tex]

Option:

x > 4; r–1(x) = 4 + StartRoot StartFraction 11 Over x EndFraction EndRoot
