Answer:

B-The graph is incorrect. He should have shaded to the right of –8.

Step-by-step explanation:

We examine the steps Alfonso follows in graphing the inequality x > -8.

Step 1: Draw a number line, and place an open circle at –8.

A number line going from negative 13 to negative 3. An open circle is at negative 8.

The first step is correct, since we use an open circle for > or < and a closed circle for \leq \:or\: \geq.

Step 2: Shade to the left of –8 to represent the infinite solutions to x greater-than negative 8.

This step is incorrect since <u>values to the left are always less than.</u>

He should have shaded to the right of -8.

<u>The error made is Option B. </u>

CHECK:

x=-7

-7>-8 (TRUE)

Line p contains point (6, -5) and is perpendicular to line q. The equation for line q is y = 3x + 5. 1) Write an equation for li
wel

Answer:

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

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. To find the line, convert the slope of q and substitute it with (6, -5) into point slope form.

y = 3x + 5 is q. It has a slope of 3. So p will have a slope of -1/3.

y - y_1 = m(x-x_1)\\y - -5 = -\frac{1}{3}(x - 6)\\y + 5 = -\frac{1}{3}x + 2\\y = -\frac{1}{3}x -3

Step-by-step explanation:

2n=1\times \left(3\sqrt{2}\right)\times \:2

2n=2 \times 3\sqrt{2}

2n=6\sqrt{2}

\frac{2n}{2}=\frac{6\sqrt{2}}{2}

Please help!!! I don’t know which one to choose which one do u choose
bixtya [17]

Answer:

A h+p ≤15

50h+500p ≥ 2500

Step-by-step explanation:

h = headphone and

p = pianos

We can only ship a maximum of 15 total

h+p ≤15

We must sell  at least 2500 dollars of product.  Headphones are 50 and pianos are 500

50h+500p ≥ 2500

Given it's midpoint and one endpoint apply the midpoint formula and solve for x and y midpoint (22,15) endpoint (18,6
Nutka1998 [239]
Midpoint formula

mid of (x1,y1) and (x2,y2) is
( \frac{x2+x1}{2}, \frac{y2+y1}{2})

so

(22,15)=( \frac{18+x1}{2}, \frac{6+y1}{2})
therefor

22=\frac{18+x1}{2}
and
15=\frac{6+y1}{2}

slv each
22=\frac{18+x1}{2}
times both sides by 2
44=18+x1
minus 18 both sides
26=x1

15=\frac{6+y1}{2}
times both sides by 2
30=6+y1
minus 6
24=y1

the other point is (26,24)
