We use quadratic formula for that one
remember that √-1=i
so
for
ax^2+bx+c=0
so
given
1x^2+5x-5=0
a=1
b=5
c=-5
solutions:
Answer:
butterflies (b)=50
butterflies in 6 months =20/100×50=10+b =60
butterflies in 12 months =2(6months)
butterflies in 12 months= 120
Answer:
work is pictured and shown
<span> −3|x + 7| = −12
* </span><span> −3(x + 7) = −12
-3x - 21 = -12
-3x = -12 + 21
-3x = 9
x = 9/-3
x = -3
</span>
* −3*[ -(x + 7)] = −12
3x + 21 = -12
3x = -12 -21
3x = -33
x=-33/3
x = -11
answer:
x = -11 and x = -3
Hi Kimberly!
-(19 - 3s) - (8s + 1) = 35
-19 + 3s -8s - 1 = 35
-19 - 1 + 3s - 8s = 35
-20 - 5s = 35
-5s =35 + 20
-5s = 55
Divide both sides by -5
-5s/-5 = 55/-5
s = -11
A+ for Algebra guaranteed! <span />
