quadratic equations can be soled by 3 methods
factorization
completing square
quadratic formula
but factorization is the simplest
Sq of 196 is 14 then x2 = 28 then 25= 5
Answer:
Step-by-step explanation:
%change=100(final-initial)/initial
%change=100(260-150)/150
%change=220/3%. (roughly 73.33%)
260(1+220/300)
260(520/300)
451 (rounded to nearest whole person)
1.) 6x=12
x=2
3(2)+3y=-9
6+3y=-9
3y=-3
y=-1
(2,-1)
2.) 7x=-35
x=-5
5x+2y=-19
5(-5)+2y=-19
-25+2y=-19
2y=-44
y=-22
(-5,-22)
3.) 4x=-16
x=-4
2(-4) +3y=1
-8+3y=1
3y=-7
y=-7/3
(-4,7/3)
4.)7x=35
x=5
2(5)+3y=-5
10+3y=-5
3y=5
y=5/3
(5,5/3)
5.) 2x=-8
x=-4
x+4y=4
-4+4y=4
4y=0
y=1
(-4,1)
Can’t answer without an image of the angle, sorry
