Answer:

$(x,y) = (1,-12)$

Step-by-step explanation:

Given

$y = 6x - 18$

Required

Find a solution

To do this, we assume a value for x, then solve for y.

Let x = 1

Substitute 1 for x in $y = 6x - 18$

$y = 6*1 - 18$

$y = 6 - 18$

$y= -12$

Hence, a solution is:

$(x,y) = (1,-12)$

The vertices of a right triangle are (0, 0), (1, 0), and (0, 1).

Alchen [17]

Answer:

(3,3)

Step-by-step explanation:

Given

$Vertices: (0,0)\ (1,0)\ (0,1)$

$Scale\ Factor = 3$

Required

Determine which can't be any of the new vertices

First, we need to determine the new vertices:

$New\ Vertex = Scale\ Factor * Old\ Vertex$

For (0,0):

$New\ Vertex = 3 * (0,0)$

$New\ Vertex = (3 * 0,3 * 0)$

$New\ Vertex = (0,0)$

For (1,0):

$New\ Vertex = 3 * (1,0)$

$New\ Vertex = (3 * 1,3 * 0)$

$New\ Vertex = (3,0)$

For (0,1):

$New\ Vertex = 3 * (0,1)$

$New\ Vertex = (3 * 0,3 * 1)$

$New\ Vertex = (0,3)$

<em>Comparing the calculated new vertices to the list of given options; (3,3) can't be any of the new vertices of the new triangle</em>

The answer for 10 2/3×31/8 rounded to the nearest whole number?

BigorU [14]

$10 \frac{2}{3} ( \frac{31}{8})$ can be changed into this equation:

$\frac{32}{3}( \frac{31}{8} )$

The 32 and 8 have a common factor of 8 and can be simplified to become this equation:

$\frac{4}{3} ( \frac{31}{1})$

Now multiply across to get $\frac{124}{3}$ which then simplifies to $41 \frac{1}{3}$ which as a decimal is 41.333 (repeating 3s). Nearest whole number is 41.

Your answer is 41
