Answer:n=2.3.5(n-2)+9=n=44.6
The answer to your problem is 10m minus 20n or 10m-20n for short.
Answer:
7x - 8y = 37
Explanation:
y+2 = ⅞(x-3) (distribute ⅞ -- x times 7/8, -3 times 7/8)
y+2 = ⅞x - 21/8 (subtract ⅞x from both sides)
y+2-⅞x = -21/8 (subtract 2 from both sides)
y-⅞x = -37/8 <--- result of -21/8 - 2
Multiply both sides by 8 to get ride of fractions
8y - 7x = -37 (rearrange)
-7x + 8y = -37
It's better to have a positive coefficient for x if you can. So multiply both sides by -1. That just means changing the sign of every term on both sides, you get
7x - 8y = 37
Answer:
5
Step-by-step explanation:
The equation of a straight line is :
y=mx+c
where m is the gradient and c is the y-intercept
so if m equals 5 then the gradient is 5
Answer:
x = -√3 /2
y = ½
Step-by-step explanation:
x = cos 150°= -√3 /2
y = sin 150° = ½
