Answer:
y= -x+5
Step-by-step explanation:
→first you need to identify 2 points. I'm using (5,0) and (0,5)
→second you need to find the slope using y2-y1/x2-x1 as your formula
5-0/0-5= 5/-5=-1
→then you need to use y-y1=m(x-x1) formula
y-0=-1(x-5)
(distribute the -1)
y-0= -1x+5 (+5 because a negative times a negative is a positive)
(combine like terms)
y= -1x+5
→once you solve you get y= -x+5
4(0.5x + 2.5y - 0.7y - 1.3y + 4)
multiply 4 by all in parentheses
(4*0.5x)+(4*2.5y)+(4*-7y)+(4*-1.3y)+(4*4
=2x+10y-28y-5.2y+16
combine like terms
=2x-23.2y+16
ANSWER:
Expression simplified 2x-23.2y+16
Hope this helps! :)
I am not quite sure on the first one but I am thinking it's Rotational and reflectional.
The second one is 240°

Answer:
Hello ?????????????? hello !!!!
This can be expanded through the tangent angle addition formula:
tan(α+β)=tanα+tanβ1−tan -α + tanβ
Thus,tan(x+y)=tanx+tany1−tan x tany
Hope it helps you
