(a)
- right-most point is (6,12) (always use this one)
- left-most point is (3,31)
- slope is 9/-3
point-slope form : y-12 = 9/-3(x-6)
my work portion:
y-12 = 9/-3(x-6)
•SIMPLIFY 9/-3
y-12 = -3(x-6)
•DISTRIBUTE -3(x-6)
y-12 = -3x+18
• MOVE -12 ONTO THE OTHER SIDE AND CHANGE ITS SIGN
y = -3x+18+12
• ADD 18 and 12
y = -3x+30
slope intercept form : y=-3x+30
(b)
i don’t understand . im sorry .
hope this helped :)
Answer:
$1083
Step-by-step explanation:
Let the actual amount be x
So since 12% convenience fee is given
It means 12%of x
That's 12/100×x
And he paid $130
So let's solve
12/100 ×x=130
12x/100=130
12x=100×130
12x=13000
Let's make x the subject of formula by dividing both sides by 12
x=1083.333
Approximately 1083
Therefore the actual fee is $1083
The square root of 16 is 4
4×4=16
4*4=16
Answer:
6:5 in simplest form
Step-by-step explanation:
First set up proportion
18.75 : 27 = 100 : x
Then multiply outer numbers and inner numbers within each other.
18.75x = 2700
Then divide 2700 with 18.75 to get 144.
And 144 is the answer..
