Answer:
x=3, y= -2
Step-by-step explanation:
Multiplying :
(4x+3y =6)*-3
(3x+5y =-1)*4
-12x -9y= -18
12x+20y= -4
Add the equations
20y-9y = -4-18
11y = -22
y= -22/11 = -2
3x +5* -2= -1
3x -10 = -1
3x = 10-1
x= 9/3 =3
To write an equation you need a slop and y intercept. To find the slop use the formula y2-y1 /x2-x1. and for the y intercept use the formula y=mx+b
Answer:
That smile tho lol
anywayssssss
b= 16 mm
Step-by-step explanation:
Pythagorean theorem is a^2 + b^2= c^2, so-
12^2 +b^2= 20^2
144+b^2=400
b^2=400-144
b^2= 256
b= 16
