Answer:
y = 
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 7 when x = 3
k =
=
, thus
y =
x ← equation of variation
When x = 7, then
y =
× 7 = 
Answer:
-9-5x
Step-by-step explanation:
they aren't the same because of the variable on 5x. You can simplify the problem to -9-5x but that's about it unless it equals something.
A. Because you would have to find the common denominator, which in this case is 24. You would change 2 1/3 to 2 8/24, 1 1/8 to 1 3/24 and 1 3/4 to 1 18/24. Add these all up and you get 5 5/24.
Answer:
2580 feet
Step-by-step explanation:
The question is essentially asking for the perimeter.
Considering the lot is a parallelogram at the least, it would be (750+540)*2, or 1290*2, or 2580
Answer:
g(n) = -29×(-4)ⁿ⁻¹
Step-by-step explanation:
This the recursive formula of a sequence g :
g(1)=-29
g(n)=g(n-1)x(-4)
now ,we want to deduce the standard explicit formula of that sequence
It’s clear from the recursive formula (above) that :
_The common ratio = -4
_the first term = -29
Then
the standard explicit formula is : g(n) = -29×(-4)ⁿ⁻¹
