Answer:
18
Step-by-step explanation:
5 scores so far + next quiz =6 scores
6 times 16=96
She has to get a quiz score sum of 96 to get an average of 16
18+15+16+14+15=78
96-78=18

<u>We </u><u>have</u><u>, </u>
- Line segment AB
- The coordinates of the midpoint of line segment AB is ( -8 , 8 )
- Coordinates of one of the end point of the line segment is (-2,20)
Let the coordinates of the end point of the line segment AB be ( x1 , y1 ) and (x2 , y2)
<u>Also</u><u>, </u>
Let the coordinates of midpoint of the line segment AB be ( x, y)
<u>We </u><u>know </u><u>that</u><u>, </u>
For finding the midpoints of line segment we use formula :-

<u>According </u><u>to </u><u>the </u><u>question</u><u>, </u>
- The coordinates of midpoint and one of the end point of line segment AB are ( -8,8) and (-2,-20) .
<u>For </u><u>x </u><u>coordinates </u><u>:</u><u>-</u>





<h3><u>Now</u><u>, </u></h3>
<u>For </u><u>y </u><u>coordinates </u><u>:</u><u>-</u>





Thus, The coordinates of another end points of line segment AB is ( -14 , 36)
Hence, Option A is correct answer
Answer: y= -2/7x-2
Step-by-step explanation:
To be parrell they have to have the same slope but different y intercepts.
so just put -2 so it will cross that point
Answer:
x=8 and y=3 (So, yes!)
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
−x+4y=4;−x+3y=1
Step: Solve −x+4y=4 for x:
−x+4y+−4y=4+−4y(Add -4y to both sides)
−x=−4y+4
-x/-1 = -4y+4/-1 (Divide both sides by -1)
x=4y−4
Step: Substitute 4y−4 for x in −x+3y=1:
−x+3y=1
−(4y−4)+3y=1
−y+4=1(Simplify both sides of the equation)
−y+4+−4=1+−4(Add -4 to both sides)
−y=−3
-y/-1 = -3/-1 (Divide both sides by -1)
y=3
Step: Substitute 3 for y in x=4y−4:
=4y−4
x=(4)(3)−4
x=8(Simplify both sides of the equation)
<u>Answer:</u>
x=8 and y=3
