Answer:

its greater than 10 but lesser than 100 because simplifying them in fractional form indeed informs u that its greater than 10

Answer:

x = 2

Step-by-step explanation:

4x +4=12

    -4.   -4

   4x.= 8

 divide both saide by 4

x. = 2

Subtract 4 from both sides

4x + 4 - 4 = 12 -4

Simplify

4x = 8

Divide both sdes by 4

4x/4 = 8/4

Simplify

x = 2

What do u need? Tell me :)

Answer:

x=18

Step-by-step explanation:

You add 1 on each side so you have 7x=126. Then you divide each side by 7, so you get x=18! Hope this helps!

Answer:

D. {(1, -8), (4, -6), (1, -6) (5,4)}

Step-by-step explanation:

The Range of a Relation

Is the set of all second elements of ordered pairs (y-coordinates). Only the elements used by the relation or function constitute the range.

For example, for the ordered pair of a relation (5,2), 5 belongs to the domain and 2 belongs to the range.

Given the range {-8,-6,4} we only have to go through the options and check which one has these values as the second element of the ordered pairs.

Note option D has y-coordinates -8, -6, -6, and 4. Those values correspond to the given range, thus the answer is

D. {(1, -8), (4, -6), (1, -6) (5,4)}

4.3 hours is your answer

Answer:

15 grams .

Step-by-step explanation:

We need to multiply the percentage as a decimal (0.30) with the amount of chocolate (50 g):

0.30*50 = 15 g

There are 15 grams of cocoa in the chocolate bar.  

Work Shown:

30% = 30/100 = 0.30

30% of 50 = 0.30*50 = 15

Here's another way to think about it: If we had 100 grams of chocolate and 30% are cocoa, then we have 30 grams of cocoa by definition of what percentage means. Divide the 100 in half to get 50, so we'll have to divide the 30 in half to get 15.

Answer:

[tex]x = 40[/tex]

[tex]y = 5[/tex]

Step-by-step explanation:

[tex]4x = 2x+80\\2x = 80\\x = 40[/tex]

Edit: Solve for Y

A straight line is 180 degrees so one side (the x side) is 160°, The Y side is 20, and  you can work backwards by -

[tex]8y - 20 = 20\\8y = 40\\y = 5[/tex]

Answer:

2³ x 3²

Step-by-step explanation:

The prime factorization of a number is the process of breaking down a number to a set of prime numbers that their product will give the original number:

          72

      2   x    36

      2 x 2 x 18

      2 x 2 x 2 x 9

       2 x 2  x 2 x 3 x 3

So;

  The prime factorization is 2³ x 3²

Answer: 4/5

Step-by-step explanation:

5(y + 2) = 4(x - 3)

Divide each side by 5

5/5(y + 2) = 4/5(x - 3)

(y + 2) = 4/5(x - 3)

This is in point slope form

(y  - y1) = m(x - x1)

Question 17

--------------------

Explanation:

We know that a = 1 so it matches with the 'a' value in y = x^2. Otherwise, the shapes wouldn't match up and they wouldn't be congruent.

The vertex we want is (h,k) = (2,-3)

Therefore,

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

y = 1(x-2)^2 + (-3)

y = (x-2)^2 - 3

================================================

Question 18

--------------------

Explanation:

The equation y = 3(x-1)^2 - 4 is in the form y = a(x-h)^2 + k which is known as vertex form.

a = 3 being positive tells us the graph opens upward and we have a min point. There is no max point as it goes on forever upward.

The min point is k = -4 which is the y coordinate of the vertex.

================================================

Question 19

--------------------

Explanation:

The equation opens up, so the value of 'a' must be positive. This narrows our choices to A or B.

We eliminate choice A because that graph is more narrow compared to y = x^2. Choice B is wider and flatter compared to y = x^2 due to 1/2 being smaller than 1.
