Answer:
D). -5(x + 2)^2 - 2.
Step-by-step explanation:
Parabola which Opens down and vertex (-2, -2) is :
f(x) = a(x + 2)^2 - 2 where a is negative
Stretch by factor 5 gives:
-5(x + 2)^2 - 2.
Answer:
Step-by-step explanation:
Given that A is a square matrix and A is idempotent
Consider I-A
i) 
It follows that I-A is also idempotent
ii) Consider the matrix 2A-I
So it follows that 2A-I matrix is its own inverse.
Plug in your Y value into the bottom equation like so:
4x + 3x-3=11, combine like terms
7x-3=11 solve for x
7x= 14
x=2
Plug in x value into first equation
y = 3(2) -3
y= 6-3, y = 3
answer: (2,3)
Answer:
x=3
Step-by-step explanation:
lets take x as the number
so
6(x-3)=x-3
since it says "6 times" we know that we will have to multiply the difference by 6 and it says the difference of a number and 3 is equal to 3 less than the number so we know that we are subtracting 3 from x
6x-18=x-3
6x-x=18-3
5x=15
x=3
