Use substitution
Since you know y = 2, you can plug in 2 for y in the first equation
2 = 4x - 10
12 = 4x
x = 3
The solution is (3,2)
X = 3, y = 2
Answer:
The total surface area of this square pyramid is
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to
we have
----> the length side of the square base
----> the height of the triangular faces
substitute the values
h(-3) = -(-3) ^2
= - 9
f(g(6)) =
g(6) = 3-6 =- 3
f(-3) = 3(-3) =-9
gh(x)= 3-(-x^2)
= 3+x^2
g^-1 (x) =
y = 3-x
exchange y and x and solve for y
x=3-y
x-3 = -y
-x+3 =y
g^ -1 (x) = -x+3
