Answer:

x = -2, x = 6

Step-by-step explanation:

18 = 3|x - 2| + 6

12 = 3|x - 2|

4 = |x - 2|

4 = x - 2    and    -4 = x - 2

x = 6    and    x = -2

How do I determine the 50th term for the sequence <br> -5, -1, 3, 7, 11
Mademuasel [1]
The sequence is going up by 4 so u have to multiply each term by four and the -5 is it’s 0th term as well it’s beginning so you have to input that in the equation as well
4(50) - 5 = 200 - 5 = 195
I’m not very good at explaining so I hope u get it

The edge of each cube used to build this rectangular prism is 13
kolbaska11 [484]

Answer:

\frac{3}{3} * \frac{2}{3} *\frac{3}{3} =\frac{2}{3} \ in^3

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

Step-by-step explanation:

The question is missing the attached figure.

The edge of each cube used to build this rectangular prism is 1/3 inch long. Based on the attached figure.

the volume of the prism = length × height × width

length = 3 * \frac{1}{3} = \frac{3}{3}

height = 3 * \frac{1}{3} = \frac{3}{3}

width = 2 * \frac{1}{3}= \frac{2}{3}

So the volume of the prism = \frac{3}{3} *\frac{3}{3} *\frac{2}{3} =\frac{2}{3} \  in^{3}

∴ The equation that shows the volume of the prism, in cubic inches

= \frac{3}{3} * \frac{2}{3} *\frac{3}{3} =\frac{2}{3} \ in^3

  2. [Multiplication Property of Equality] Multiply 2 on both sides:                      \displaystyle \frac{1}{3} = \frac{1}{\sqrt{x}}
  3. [Multiplication Property of Equality] Cross-multiply:                                      \displaystyle \sqrt{x} = 3
  4. [Equality Property] Square both sides:                                                           \displaystyle x = 9

<em>y-coordinate</em>

  1. Substitute in <em>x</em> [Function]:                                                                                \displaystyle y = \sqrt{9}
  2. [√Radical] Evaluate:                                                                                         \displaystyle y = 3

∴ Coordinates of A is (9, 3).

Which equation represents a line that passes through (2,-1/2) and has a slope of 3 ?
Anna11 [10]

Answer:

C. y + \frac{1}{2} = 3(x - 2)

Step-by-step explanation:

Given

Point:  (2,\frac{-1}{2})

Slope: 3

Required

Equation of line

Let m represents the slope of the line;

m is calculated as thus

m = \frac{y - y_1}{x - x_1}

where (x_1,y_1) = (2,\frac{-1}{2})

So; x_1 = 2; y_1 = \frac{-1}{2}

m = 3

By substituting the right values in the formula above;

m = \frac{y - y_1}{x - x_1} becomes

3 = \frac{y - \frac{-1}{2}}{x - 2}

Multiply both sides by (x - 2)

3 *(x - 2) = \frac{y - \frac{-1}{2}}{x - 2} *(x - 2)

3 *(x - 2) = (y - \frac{-1}{2})

3 *(x - 2) = (y + \frac{1}{2})

3(x - 2) = (y + \frac{1}{2})

3(x - 2) = y + \frac{1}{2}

Reorder

y + \frac{1}{2} = 3(x - 2)

Hence, the equation that represents the line is y + \frac{1}{2} = 3(x - 2)
