Answer:
y = -1/4x - 1
Step-by-step explanation:
4x - 1
Change 4x to -1/4 to make the slope perpendicular
Then put (4, -2) on x and y to find b
-2 = -1/4(4) + b
-2 = -1 + b
-2 + 1 = -1
b is -1
So your final answer in slope intercept form is y = -1/4x - 1
x and y varies directly and the equation will be: y=480.x
Step-by-step explanation:
We need to write the equation to represent the relationship between x and y
We can find if x and y varies directly or indirectly.
Checking if x and y varies directly
if x and y varies directly then y=kx or y/x = k then k is constant
if x=2 and y=960 then k is:
k=y/x= 960/2 = 480
if x=2 and y=960 then k is:
k=y/x = 1440/3=480
if x=2 and y=960 then k is:
k=y/x= 2880/6=480
if x=2 and y=960 then k is:
k=y/x=3840/8 = 480
Since y/x = 480 for every value of y and x in the table, so x and y varies directly and the equation will be:
y= kx
y=480.x

area = I x w
so 25 x 13 = 325 square inches
Answer:
$15
Step-by-step explanation:
$3 correspond is the 20% discount of the total price.
If the total price is x then you can express the discount as:
0.20x = 3
x = 3/0.20
x = 15
