Answer:

\boxed{\sf (b) \ x = -3}

Step-by-step explanation:

\sf Solve \:  for \:  x: \\  \sf \implies 3 - 2x = 9 \\  \\  \sf Subtract  \: 3  \: from \:  both  \: sides: \\  \sf \implies (3 -  \boxed{3}) - 2x = 9 -  \boxed{3} \\  \\  \sf 3 - 3 = 0 :  \\  \sf \implies - 2x = 9 - 3 \\  \\  \sf 9 - 3 = 6 :  \\  \sf \implies  - 2x =  \boxed{6} \\  \\  \sf Divide  \: both \:  sides  \: of  \:  - 2 x = 6  \: by  \:  - 2: \\  \sf \implies  \frac{ - 2 x}{ - 2}  =  \frac{6}{ - 2}  \\  \\  \sf \frac{ - 2}{ - 2}  = 1  :  \\  \sf \implies  x =  -  \frac{6}{2}  \\  \\  \sf \implies x =  -  \frac{3 \times  \cancel{2}}{ \cancel{2}}  \\  \\  \sf \implies x =  - 3

Answer:

<h2><em>X=</em><em>-</em><em>3</em></h2>

<em>Option </em><em>B </em><em>is </em><em>correct </em><em>.</em><em>.</em><em>.</em>

<em>solution \\ 3 - 2x = 9 \\ or \:  - 2x = 9 - 3 \\ or \:  - 2x = 6 \\ or \: x =  \frac{6}{ - 2}  \\ x =  - 3</em>

<em>hope </em><em>this </em><em>helps.</em><em>.</em>

<em>Good </em><em>luck</em><em> on</em><em> your</em><em> assignment</em><em>.</em><em>.</em><em>.</em>

What is the answer
Mrac [35]

Answer:

The coordinates of H′ are (-2,0).

Step-by-step explanation:

It is given that square EFGH stretches vertically by a factor of 2.5 with respect to the x-axis to create rectangle E′F′G′H′.

If a figure stretches vertically by a factor of 2.5 with respect to the x-axis, then the x-coordinates remains same and the points which lie on the axis are also remains the same after stretch.

It is given that the coordinates of H are (-2,0). This point lie on the x-axis, therefore it will remains the same after stretch.

Therefore the coordinates of H′ are (-2,0).

Classify each sequence as arithmetic, geometric or neither
Karolina [17]

Answer:

Geometric sequence = ⁵/9, ⁵/3, 5, 15, 45. . .

Arithmetic sequence = 16, 11, 6, 1, -4 . . .

Step-by-step explanation:

A geometric sequence is a sequence of numbers, in which every number in the sequence after the first term is multiplied by a common ratio, which gives us the next term. The common ratio is the ratio of a term to the term before it.

On the other hand, an arithmetic sequence is a sequence of number have a common difference between each consecutive terms. This common difference is gotten by subtracting a term from the term before it.

Now let's examine each sequence given:

==>16, 11, 6, 1, -4 . . .

11 - 16 = -5

6 - 11 = -5

1 - 6 = -5

-4 - 1 = -5

This is an arithmetic sequence. The commons difference "-5" is the same

==>⁵/9, ⁵/3, 5, 15, 45. . .

⁵/3 ÷ ⁵/9 = ⁵/3 × ⁹/5 = ⁹/3 = 3

5 ÷ ⁵/3 = ⁵ × ⅗ = 3

15 ÷ 5 = 3

45 ÷ 15 = 3

The common ratio "3" is the same. This is a geometric sequence.

For questions 1-3, decide for each graph whether the equation shown is a function. Label each graph
ruslelena [56]

Answer:  Not a function

<u>Step-by-step explanation:</u>

The graph fails the vertical line test.  In other words, when you draw a vertical line anywhere through the curve, the line passes through two points.

Bonus: If you do not have a graph, it is not a function if there is one x-value that has two different y-values.

For example, If (1, 2) and (1, -2) lie on the curve, then it is NOT a function because the x-value (1) has two different y-values (2 & -2).
