Offers are parallel because they would never intersect
Naw bruv i’m doing the same problems rn and i’m struggling gl tho
General rule for multiplication or division between 2 numbers:
if you multiply or divide by:
1. same signs, answer is postive
2. different signs, answer is negative
so we have a -12 and a +9.9 so the answer is negative
then you divide 12 by 9.9
so the answer is negatiive, remember that
then divide as if positive
do
12/9.9
multiply by 10/10
120/99
simplify
120/99
factor out the 3/3
40/33
do the division (you can use calculator)
1.212121212121212121212121212
then it is negative so
-1.212121
Answer:
D. y = x - 3
Step-by-step explanation:
First, find the slope (m) of the line it is perpendicular to using the points of the line, (4, 2) and (-1, 7):
Thus, the slope (m) of the line that is perpendicular to the line that runs through (4, 2) and (-1, 7) would be the negative reciprocal of -1.
The slope (m) if the line that is perpendicular to the other line = 1
Thus, substitute m = 1 and (a, b) = (1, -2) into y - b = m(x - a)
y - (-2) = 1(x - 1)
y + 2 = x - 1
Subtract 2 from both sides
y = x - 1 - 2
y = x - 3
Answer:
Step-by-step explanation:
focus distance=9
a=2 f²=a²+b² ==> b²=9²-2²=77 ==> b=√77
