Answer:
w=2, -3
Step-by-step explanation:
minus 25 from each side
1+-25+4w^2+4w=25+-25
combine like terms
-24+4w^2+4w=0
factor out the greatest Common factor
4(-6+w+w^2)=0
factor a trinomial
4((-3+-1w)(2+-1w))=0
I hope this helps!
7/10 - 1/4 use common denominators
28/40 - 10/40 = 18/40 = 9/20
Answer:
Step-by-step explanation:
Gradient of a line =( y2 - y1)/x2 - x1
From the question, x1=4,y1=-1,x2=1,y2=0.
Therefore, substitute for these values in the above formula
m = 0-(-1)/1-4
= 0+1/-3
= -1/3.
Therefore, y-y1/x-x1 = -1/3
y - y1 = -1/3(x - x1)
y - (-1) = -(x-x1)/3
y+1 = - (x - 4)/3
Multiply through by 3
3y+3= -x+4
3y +x=4-3
x+3y= 1
Therefore the answer is A.
