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.

Answer:

only the green and pink line repent a proportional relationship

Answer:

remember,a percent means "per 100".You can describe the change as a fraction comparing the amount of change to the original and then use a proportion to rewrite your problem as a percentage out of 100.

[tex]y=3\sqrt{x-1}[/tex]

The domain is x ≥ 1 as x cannot be less than 1 or else it'll become negative in square root which you cannot find a value.

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)}

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!

Step-by-step explanation:

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

Step-by-step explanation:

Answer:

f(2) = 28

Step-by-step explanation:

[tex] \rm f(x) = 8 {x}^{2} + 4x - 12 [/tex]

[tex] \rm Evaluate \: 8 x^2 + 4 x - 12 \: where \: x = 2: \\ \\ \rm \implies f(2) = 8 \times {2}^{2} + 4 \times 2 - 12 \\ \\ \rm \implies f(2) = 8 \times 4 + 8 - 12 \\ \\ \rm \implies f(2) = 32 - 4 \\ \\ \rm \implies f(2) = 28[/tex]

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)

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:

y=4x+3

y=-2x+3

Step-by-step explanation:

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
