Andrew answered the following inequality, his work is shown below:
−5x − 7 ≤ − 52
−5x ≤ −45
x ≤ 9
What mistake did he make?
A. He should have added 7 to both sides in the first step.
B. He should have flipped the symbol in the last step.
C. He should have divided both sides by -5 in the first step.
D. He should have divided negative 45 by negative 5 and gotten -9.

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

40 i don’t know lololol

where is the graph? need more info

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
