I’m pretty sure it’s D, if you count your boxes from the origin you go up four and over one so it would be 4x for slope
X⁴ - 81 = x⁴ - 9² (Difference of 2 squares, then we an write it:
(x²-3)(x²+3) =0, → then (x²-3) = 0 and (x²+3)=0
(x²-3) = 0 → x² = 3 → x = +√3 and x = -√3
(x²+3) =0 → x² = -3 → x = +√-3 and x = -√3→ or i√3 AND x = -i√3
A{ -3 , +3 , -i√3 , i√3}
A) 5x⁴-8 <----- the tell-tale guy is the exponent of the variable, is 4, so the degree is 4, 5x then minus then 8, two terms, a BInomial
b) 4a²-2a-16 <---- same tell-tale guy, a² has a higher exponent than say "a", so, the degree is the higher exponent, degree of 2
it has 3 terms, thus is a TRInomial
c) 9m³ <---- well, is the only term, variable exponent is 3, so, degree of 3
only one term means is a MONOmial.
Answer:
3/2 or 1.5
Step-by-step explanation:
So, We Need To Write An Equation To Find This:
AD = lAl + lDl
So:
AD = l-7l + l8l
l-7l= 7.
AD = 7 + 8
7+8 = 15
AD = 15
So, AD = 15. This Means That The Answer Is B.
