Answer:
1
Step-by-step explanation:
The slope of the perpendicular is the negative inverse of the slope of the line.
m = -1 / (-⅓)
m = 3
The slope between the two points is 3, so:
3 = (15 − 6) / (4 − n)
3 (4 − n) = 9
4 − n = 3
n = 1
Answer:
missing exponent is ^3
Step-by-step explanation:
450 divided by 2 is 225. 225-50=175. 225+50=275
John has 275 and Andrew has 175.
In order to get this answer, first you divide the whole number by 2. Then you get the number 225. You then have to subtract 50 from 225 because John gets 50 more than Andrew. Then for John, you have to add 50 to 225. To self-check the answer, here is the formula: 175+275=450. Remember that on these kind of word problems, you first divide the whole. Then subtract and add the number that one person gets more than the other person.
PEMDAS
3 ( x - 7 ) = 9 ( 4x + 5 )
3x - 21 = 36x + 45
-36
-33x - 21 = 45
+21
-33x = 66

-33 -33
x = -2
Your answer should be -2
I hope this helps!
