The function is equal to (x+2) / (x+2)(x-2), so when you simplify, it would be 1/(x-2). This means that there is a hole in the graph at x=-2, and a vertical asymptote at x=2.
Answer:they alk are right
Step-by-step explanation:
-2(1+2x)=7-x
-2(1)=-2 -2(2x)=-4x rewrite
-2-4x=7-x combine like terms add two to both sides 7+2=9; add x to both sides -4x+x=-3x rewrite -3x=9 divide -3 from both sides 9/-3=-3 rewrite
X=-3
Hope this helps have a nice day!
Okay, let's use x for the 24 page packages and y for the 30 page packages:
x + y = 9
x = -y + 9
Now here's the second equation:
24x+30y = 258
We can input y into our second equation:
24(-y + 9) + 30y = 258
-24y + 216 + 30y = 258
6y = 42
y = 7
9 - 7 = 2, so:
Joann bought 7 :30 paper pakages

First magnitude...
d^2=5^2+3^2
d^2=25+9
d^2=34
d=√34
now for direction...
tanα=y/x
α=arctan(y/x) and we know y=5 and x=3 so
α=arctan(5/3)
α≈59.03624
So the vector of her ride is:
√34, 59.03624° or if you prefer...
√34, 59°2'10" (in standard angle position)
