Answer:
y=12x-4
Step-by-step explanation:
To find the slope intercept form, we know the m(slope) but we need to find b.
y and x is given to us, so we can find b.
Plug in the numbers provided into the slope intercept form.
y=mx+b
20=(12)(2)+b
20=24+b
To find b, we have to get b by itself. So, we subtract both sides by 24.
-4=b
Now that we found b, we can plug this into the equation.
y=12x-4
Step-by-step explanation:
MID POINT =[(X1 +X2)/2 , (Y1 +Y2)/2]
WE KNKW THAT A(2,–8) AND THE MID POINT IS (3,3)
SUBSTITUTING INTO THE EQUATION ABOVE
(3,3) = [(2+ X2)/2 ,(–8+ Y2)/2]
EQUATING THE X COORDINATES
=> 3 = (2+ X2)/2 (CROSS MULTIPLY)
=> 6 = 2 + X2
X(subscript 2)= 4
EQUATING THE Y COORDINATES
=> 3 =(–8 +Y2)/2 (CROSS MULTIPLY)
6 = –8 +Y2
=> Y(subscript 2)= 14
THEREFORE THE COORDINATES OF B ARE (4 ,14)
hope this helps :)
Answer:
She wrapped 5 presents
Step-by-step explanation:
She used 2cm to wrap each present
8cm = 4x
x is the amount of presents
divide by 4
x= 2 cm
Given 10 cm, divide by 2 to determine amount of x, or presents
