-The equation is actually
5x^2 -2x+1=0;
-The discriminant is b^2 -4ac=4-4•5•1=4-20=-16
-this means that the equation has no real number solutions
Answer:
<em>EF = 5 units</em>
Step-by-step explanation:
If ΔABC and ΔDFE are congruent, then
AB = DF
BC = FE
CA = ED
and
angles A and D are congruent
angles B and F are congruent
angles C and E are congruent
Answer:
3
Step-by-step explanation:
because there are only three pictures
-3x+5y=80 if the x = -10 and y = 10
x+5y=40 if the x= -10 and y= 10
[(100-15)/100 * $3]
= $2.55
$5.35 - $2.55
= $2.80 |80% paper|
80/100 = 2.80/x
4/5 = 2.80/x
4x = 14
x = 3.5
Original price of the paper = $3.50
