Answer:

C. 2x-y>-7

Step-by-step explanation:

The Line is not part of the region since is drawn in the graph using a dotted line, but we still need to find its equation.

The equation of a line is y=mx+b, where 'm' is the slope.

'm' can be obtained using the following formula.

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

To find the slope, as well 'b' we need points from the line, those will be (-6,-5), (0,7) as (x2,y2) and (x1,y1) respectively

Evaluating those point in the formula we have 'm' =2

Using now the above result and the point (0,7) in the equation y=mx+b, we obtain the value for 'b'.

7=2*0+b7

b=7

Hence our line is y=2x+7, and if we write it in standard form we obtain the following> y-2x=7.

Now, since our line is not part of the region, and the region is below that line, there is the < sign.

Hence the inequality that corresponds to the figure is y-2x<7 or, if we multiply by -1 (changin orientation of signs)   2x-y>-7

A typical tip in a restaurant is 18% of the bill. If the bill is 150,what would the typical tip be​
Natasha_Volkova [10]

<u><em>You want to leave a 18% tip on a meal that cost $150.</em></u>

<u><em>First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.</em></u>

<u><em>Second, you need to find out what 18% of your $150 meal cost is.This is always done by multiplying 0.18 by $150.00, or</em></u>

<u><em></em></u>

<u><em>0.18 x $150.00=$27.00.</em></u>

<u><em>So, the amount of tip you are going to leave is $27.00.</em></u>

<u><em></em></u>

<u><em>This makes the total cost of your meal (to write on your charge slip or other payment)</em></u>

<u><em></em></u>

<u><em>$150.00 + $27.00 = $177.00. </em></u>

If the triangle on the grid below is translated by using the (x,y) -&gt; (x+5, y-2) rule, what will be the coordinates of B'?
Art [367]
We know that
the coordinates of point B ( -5,0)

the translation has the following rule
(x,y)--------> (x+5, y-2)
so
(-5,0)-----> (-5+5,0-2)-----> (0,-2)

the answer is
<span>(0, –2) </span>
