Answer:

x=0

Step-by-step explanation:

Assuming the two sides are equal length

2x+15 =x+15

Subtract 15 from each side

2x =x

Subtract x from each side

2x-x = x-x

x=0

Step-by-step explanation:

<em>Given</em><em>, </em>

<em>RSTU</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>parallelogram</em><em>, </em>

<em>so</em><em>,</em><em> </em><em>we</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em>,</em>

<em>let's</em><em> </em><em>find it</em><em>, </em>

<em>2</em><em>x</em><em>+</em><em>1</em><em>5</em><em> </em><em>=</em><em> </em><em>x</em><em>+</em><em>1</em><em>5</em><em> </em><em> </em><em> </em><em>(</em><em>opposite</em><em> </em><em>side of</em><em> </em><em>parallelogram</em><em> </em><em>are</em><em> </em><em>equal</em><em> </em><em>and</em><em> </em><em>parallel</em><em>)</em>

<em>2</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>5</em><em>-15</em>

<em>x</em><em>=</em><em>0</em>

<em>Therefore</em><em>, </em><em>the</em><em> </em><em>value of</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>0</em><em>.</em>

<em>If</em><em> </em><em>you</em><em> </em><em>have</em><em> </em><em>doubt</em><em>.</em><em> </em><em>then</em><em> </em><em>let's</em><em> </em><em>clear</em><em> </em><em>it</em><em> </em><em>by</em><em> </em><em>putting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em>.</em>

<em>so</em><em>,</em><em> </em><em>2</em><em>×</em><em>0</em><em>+</em><em>1</em><em>5</em><em> </em><em>=</em><em> </em><em>0</em><em>+</em><em>1</em><em>5</em>

<em>1</em><em>5</em><em>=</em><em>1</em><em>5</em><em> </em><em>{</em><em>as</em><em> </em><em>already</em><em> </em><em>said</em><em> </em><em>that</em><em> </em><em>the</em><em> </em><em>sides</em><em> </em><em>are</em><em> </em><em>equal</em><em>}</em>

<em>proved</em><em>.</em><em>.</em>

<em>so</em><em>,</em><em> </em><em>the</em><em> </em><em>value of</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>0</em><em>.</em>

Suppose z is proportional to the square root of x. If z = 717 when x = 9, find the proportionality constant k.??
Dahasolnce [82]

Answer:

  239

Step-by-step explanation:

Write the equation. Fill in the given values, and solve for the unknown,

  z = k√x

  717 = k√9

  k = 717/3 = 239

The constant of proportionality is 239.

Determine the equation of each line with the following properties:
iris [78.8K]

Answer:

a) y =2/3 x + 7.

b) x = -1

c) y = -4/5 x - 1/5

d) y = -3/2 x + 5/2.

Step-by-step explanation:

a) Intercept form y = mx + b where m = 2/3 and  b = 7

b) y can take any value but x is always -1.

c) Slope m = (-1-3)/ (1 - -4)

= -4/5

Using point-slope form where m = -4/5 and x1 y1 = 1 , -1:

y - y1 = m(x - x1)

y - -1 = -4/5(x - 1)

y + 1 = -4/5x + 4/5

y = -4/5 x - 1/5

d)  The slope m of the line perpendicular to this line is:

-1 / 2/3

m = -3/2.

When x = -1 , y = 4 so using the slope intercept form of a line

y = mx + b

4 = -3/2 * -1 + b  where b = the y-intercept.

4 = 3/2 + b

b = 4 - 3/2 = 5/2.

The equation is  y = -3/2 x + 5/2.
