Answer:
x = -1/8 x (Option D)
Step-by-step explanation:
First find the slope which is rise / run = difference in y values / corresponding difference in x values
= ( 0.5 - (-0.5) / (-4 - 4)
= 1 / -8
= -1/8
Using the point-slope form of the equation of a line
y - y1 = m(x - x1), here we have m = -1/8 and (x1, y1) = ( -4, 0.5) , so:-
y - 0.5 = 1/8(x - (-4)
y - 0.5= -1/8(x + 4)
y = -1/8 x - 0.5 + 0.5
y = -1/8 x (answer)

Angles 5 and 1 are corresponding angles because the line intersects two parallel lines
Answer:
it is different because ax^2+bx+c with a ≠1 means that a is not equal to 1
and x^2+bx+c is different because x^2 is equal to 1x^2 but we dont usually write the 1 because it doesnt make any difference

Answer:
92.5
Step-by-step explanation:
The total of Megan's scores is ...
94 +81 +87 +93 = 355
so her current average is 355/4 = 88.75
The score (s) Megan needs for a 90 average is ...
(2/3)(88.75) +(1/3)s = 90
2(88.75) +s = 270 . . . . . . . . multiply by 3
s = 270 -177.5 = 92.5
Megan needs a score of 92.5 on her final to have an overall average of 90.
