The variable x equals x=7
Answer:
$1200
Step-by-step explanation:
Let the roof be square shaped
Area of the roof = L²
L is the side length of the roof
Given
L = 40ft
Area of the roof = 40²
Area of the roof = 1600ft²
If plants used for a green roof cost $0.75 per square foot, this means
1 ft² = $0.75
Let the cost needed to cover both sides of the roof be y, hence;
1600ft² = y
Divide both expressions
1/1600 = 0.75/y
y × 1 = 0.75×1600.
y = 0.75×1600
y = 1200
Hence it will cost $1200 to cover both sides of the roof
The equation is y=2x+5 and there are two options like that so yea
Answer:
1/40
Step-by-step explanation:
2/4*7/10
=2/28/10
=0.0714/10
=0.00714
Rational function:
A rational function is any function which can be defined by a rational fraction,
that is an algebraic fraction such that both the numerator and the denominator are polynomials
Let's assume
numerator polynomial is p(x)
denominator polynomial is q(x)
so, we can write rational function as
now, we will check each options
option-A:
we know that
we always get hole from rational function only
For exp:
Here , hole is at x=3
so, this is TRUE
option-B:
rational functions can not have irrational numbers
because we have both numerator and denominators are polynomial
so, this is FALSE
option-C:
We can get slant asymptote from rational function
For exp:
Here , slant line is y=x-3
so, this is TRUE
option-D:
Rational functions can have axis of symmetry
so, this is TRUE
