A=-1 or a=-3 hope this helps
4x^2-3x+4y^2+4z^2=0
here we shall proceed as follows:
x=ρcosθsinφ
y=ρsinθsinφ
z=ρcosφ
thus
4x^2-3x+4y^2+4z^2=
4(ρcosθsinφ)^2-3(ρcosθsinφ)+4(ρsinθsinφ)^2+4(ρcosφ)
but
ρ=1/4cosθsinφ
hence we shall have:
4x^2-3x+4y^2+4z^2
=1/4cosθsinθ(cosθ(4-3sinφ))+4sin^2(φ)
Commission = 20% x 85 = $17
Salary = $82 + $17 = $99 <=== this much she made.
ANSWER:
5a+2b
add the like terms together
Yeah bro just take the 2 and subtract on both side so the y is left alone flip the 100 so now its 001 divide it by 1 and the answer is 007 like the spy.
