It is more effective if I explain using examples. So, for multiplication, you just have to multiply the magnitude, then add the exponents of the base 10. For example, when you multiply 5.2×10³ and 1.6×10², the solution would be:
(5.2)(1.6)(10³⁺²) = 8.32×10⁵
Now, for division, you will have to divide the magnitudes, and subtract the exponents by numerator minus denominator. The solution is as follows:
(5.2/1.6)(10³⁻²) = 3.25×10¹
It’s hard to help, since there’s no picture :/
5y^2-2y-2 = 0
y = 1/5+ √11/5 or 1/5 - √11/5
You can write it as 9/10 because the other terms will cancel out.
Answer:
y=1/3x+1
Step-by-step explanation:
y=mx+b
y=1/3x+b
2=1/3(3)+b
2=1+b
1=b
y=1/3x+1
