blagie [28]3 years ago
8 0

We will check each options and verify it

(a)

18-2m

we can plug m=2

18-2\times 2

18-4

14

so, this is FALSE

(b)

7x-\frac{x}{3} >19

we can plug x=3

7\times 3-\frac{3}{3} >19

21-1 >19

20 >19

so, this is TRUE

(c)

6x-1>4x+5

we can plug x=3

6\times 3-1>4\times 3+5

18-1>12+5

17>17

so, this is FALSE

(d)

2x^2-3x+1

now, we can plug x=2

2(2)^2-3(2)+1

8-6+1

3

So, this is FALSE

Which expressions are equivalent to R16? Check all that apply.
Ilya [14]

Option C:  (6^{-4})^{-4}

Option D:  (6^{-2})^{-8}

Option F:  (6^8)^2

Solution:

Given expression: 6^{16}

To find which expression is equivalent to the given expression.

Let us solve this using exponent rule: \left(a^{b}\right)^{c}=a^{b c}

Option A: (6^{0})^{16}

(6^{0})^{16}=6^{0 \times 16}= 6^0

It is not equivalent expression.

Option B: (6^8)^8

(6^{8})^{8}=6^{8 \times 8}= 6^{64}

It is not equivalent expression.

Option C:  (6^{-4})^{-4}

(6^{-4})^{-4}=6^{(-4 )\times (-4)}= 6^{16}

It is equivalent expression for the given expression.

Option D:  (6^{-2})^{-8}

(6^{-2})^{-8}=6^{(-2) \times (-8)}= 6^{16}

It is equivalent expression for the given expression.

Option E:  (6^{-1})^{16}

(6^{-1})^{16}=6^{(-1) \times 16}= 6^{-16}

It is not equivalent expression.

Option F:  (6^8)^2

(6^{8})^{2}=6^{8 \times 2}= 6^{16}

It is equivalent expression for the given expression.

Hence (6^{-4})^{-4}, \ (6^{-2})^{-8}, \ (6^8)^2 are the equivalent expressions.

Option C, Option D and Option F are correct answers.

The vertex of the parabola would be located at which coordinates<br> -6,3<br> 6,3<br> 3,-6<br> 3,6
Artemon [7]
<h3><u>Explanation</u></h3>
  • Given Equation

y = 4 {(x - 6)}^{2}  + 3

  • Vertex Form

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

where a-term determines how wide/narrow/upward or downward of the graph.

h-term determines the changes of graph for x-axis

k-term determines the changes of graph for y-axis.

The vertex of parabola is at (h,k).

y = 4 {(x - ( + 6)})^{2}  + ( + 3)

Therefore, h = 6 and k = 3.

<h3><u>Answer</u></h3>

<u>\large \boxed{(6,3)}</u>
