How do I write "x is a nonnegative number" using an inequality symbol?

If it's "non-negative", then it must be positive. If it's positive, then it must be more than zero. Use an inequality symbol to write "X is more than zero".

If a squareroot is multiplied by the same (like your example) it turns the number in squareroot as natural number.

squareroot 13 • 3 squareroot 13 = 13•3= 39

Hope it helps!

Consider two parallel line segments.

Kaylis [27]

Answer:

Part A: -3/7

Part B: y = -2

Step-by-step explanation:

Parallel lines have the same slope. Find the slope of CD. Then substitute it to find the value needed for AB.

The slope formula is

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{4-1}{-5-2} = \frac{3}{-7}$

Use the same formula and solve for y.

$m = \frac{y_2-y_1}{x_2-x_1}\\\\-\frac{3}{7}= \frac{y--5}{-6-1} \\\\\frac{3}{-7} =\frac{y+5}{-7}\\\\3 = y+5\\3-5 = y\\-2 = y$

If XY = 5x-3 and XZ=44, find x and the value of YZ

mixer [17]

The midpoint of a line divides the line into equal halves.

<em>The value of x is 5</em>
<em>The value of YZ is 22</em>

<em />

Given that:

$XY = 5x -3$

$XZ = 44$

Y is the midpoint of XZ. So:

$XZ = 2 \times XY$

$44 = (5x - 3 ) \times 2$

$44 = 10x - 6$

Collect like terms

$10x = 44 +6$

$10x = 50$

Divide both sides by 10

$x = 5$

Recall that: Y is the midpoint of XZ

This means that:

$YZ = \frac12 XZ$

$YZ = \frac12 \times 44$

$YZ = 22$

Hence, the value of x is 5 and YZ is 22
