<span>To predict f(x) when x equals 8 we simply substitute.
So f(x) = 25x2 28x + 585
f(8) = 25 (8)^2 - 28 (8) + 585
f(8) = 25 * 64 - 224 + 585
f(8) = 1600 - 224 + 585 = 1961
Hencse f(8) = 1961</span>
Z/3+10=-7/10
multiply both sides
10z + 300 = -21
move the constant to the right
10z= -21 - 300
Calculate
10z = -321
divide both sides ^^
answer : z=-321/10
