plzzzzzzzzz help and the answer choice i have on there is not the answer just where i accidently hit lol

Answer:

Infinitely many solutions

Step-by-step explanation:

Note that 2(2x+3y=12) is 4x+6y=24, which is the first equation. Therefore, by canceling the equations out, you have 0=0, which means whatever one side equals, the other side ALWAYS equals that.

Answer:

g(f(x)) = x

Yes, the functions are inverses.

Step-by-step explanation:

Hi there!

We're given:

[tex]f(x) = 8x-7[/tex]

[tex]g(x)=\displaystyle\frac{x+7}{8}[/tex]

To solve for g(f(x)), plug f(x) into g(x) as x:

[tex]g(f(x))=\displaystyle\frac{(8x-7)+7}{8}\\\\g(f(x))=\displaystyle\frac{8x-7+7}{8}\\\\g(f(x))=\displaystyle\frac{8x}{8}\\\\g(f(x))=x[/tex]

Because g(f(x)) = x, the two functions are inverses.

I hope this helps!

Answer:

(B) all surveys have a sampling error.

Step-by-step explanation:

Answer:

51°

Step-by-step explanation:

We know that all angles in a triangle add up to 180°

We have one of them, 68° for now.

We also know the angle on the outside of the triangle that forms with one side being extended. That side is a straight line (180°)

Which means the interior angle there would be 180-119 = 61°

This means that we have 2 out of 3 angles now. Now we just add them up and subtract them from 180°.

180° - (68+61) = 51° is our final answer.

Let me know if that makes sense, or if you have any other questions.

Hope I helped! :)

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

2(x+9)+142=180       corresponding angles are equal and angles on a straight line=180

2(x+9)=180-142

x+9=38/2

x=19-9

x=10

Step-by-step explanation:

2 times = +1 dollars for Paula, +0.50 dollars for Jacki

Try multiplying it the least amount of times to Paula can have more and so 20 times and Paula will have 20 dollar sand Jacki will have 19.75, therefore she needs to do 20 laps.

Answer: don’t know what your requesting but a lot of these are wrong

Answer:

[tex]x = 2\sqrt{55}[/tex]  

Step-by-step explanation:

Given the values for the leg and hypotenuse:

a (leg) = 6 cm

c (hypotenuse) = 16 cm

Use the Pythagorean Theorem to find the value of the other leg, x:

[tex]x = \sqrt{c^{2} - a^{2} }[/tex]

[tex]x = \sqrt{16^{2} - 6^{2} }[/tex]

[tex]x = 2\sqrt{55}[/tex]  

Answer:

Your answer is [tex]\sqrt{220}[/tex] or 14.8323969...

Step-by-step explanation:

[tex]A^{2} +B^{2} =C^{2} \\x^{2} + 6^{2} =16^{2}[/tex]

[tex]x^{2} =16^{2} -6^{2} \\[/tex]

[tex]x^{2}[/tex] = 256 - 36

x = [tex]\sqrt{220}[/tex]

Answer:

a) 3x^2 + x - 2

b) 28m

Step-by-step explanation:

a) Since the Area for a normal square is b*l (base x length)

Do the same with this (Using FOIL ig)

(3x - 2) * (x + 1)

3x^2 + 3x - 2x - 2

3x^2 + x - 2

b) Since it's asking us to find out what the number will be while x = 3m, just substitute 3 for every "x" in the answer we got for a

3(3)^2 + (3) - 2

3(9) + (3) - 2

27 + 3 - 2

30 - 2

28m

Therefore the actual area of this rectangle is 28m

Answer:

Step-by-step explanation:

Step-by-step explanation:

The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).

The expressions that represent the perimeter of the square are  p = 4(6m-3) and p = 24m - 12. And p = 24m - 12 is the simplest form of the expression.

A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.

Given:

The side of the square is 6m-3 unit.

And all the sides of the squares are equal.

And the perimeter p of the square is,

= the sum of all the sides.

p = 4 x one side.

p = 4(6m-3)

The above expression represents the perimeter of the given square.

Simplifying,

p = 24m - 12

This is the simplest form of the expression.

Therefore, the required expression are p = 4(6m-3) and p = 24m - 12.
