Answer:
129
Step-by-step explanation:
(4*2^2+8*2)= 32
(3*2^2-5*2+20)=22
(7*2+30)=44
32+31+22+44=129
Answer: n=2
Step-by-step explanation:
Get graph paper make a graph mark them on your graph and since it says (n,-2) its going down because of the negative 2 i don't think this helped but if it did
I'm sorry for my earlier mistake! The answer is -5-5/3=<span>-20/3</span>
A perpendicular line has an opposite reciprocal slope. This means that the new line will have a slope of -4/3x. Plug in x and y into the equation y=Mx +b where m is the slope (-4/3):
-3=(-3/4)(-3) + b
and isolate b:
b-3=(-3/4)(-3)
b=(-3/4)(-3) +3
b=9/4+3
b=21/4
The final equation is y= -4/3x + 21/4
The y intercept is (21/4).
