Answer:
Step-by-step explanation:
After derive a couple of times you can see
Replacing n by 7 and x by 1 we get
You have the right concept for problem #1 but made an error.
x = -x + 2
2x = 2 (added "x" to both sides ---<em>this is where you made the error</em>)
x = 1 (divided both sides by 2)
Given that y = 3x – 10 and y = -2x -15
(-1 , -13)
substituting equation 1 to the equation 2
Y = 3x – 10
3x – 10 = -2x -15
3x + 2x = -15 + 10
5x = -5
X = -1
Substitute -1
Y = 3(-1) – 10
Y = -13

Rule: if you have graph of function y=f(x) and a>0, then:
1. y=f(x-a) is translation a units right;
2. y=f(x+a) is translation a units left;
3. y=f(x)-a is translation a units down;
4. y=f(x)+a is translation a units up;
Since g(x)=f(x+2)-5, then firstly you have to translate the graph of function y=f(x) two units left and secondly 5 units down.
You have r^2 = 64 and want to find the square root of 64, which we'll call r.
√(r^2) = r = plus or minus √64
or: r = plus or minus 8
