Aclass is trying to eliminate t from the parametric equations x=t^2+3 and y=4t. beth says that she can write t=sqrt(x-3) to eliminate the parameter. why is this wrong? she should have added 3 to x, not subtracted. she should always solve for t as a function of y. she should have taken both the positive and negative square root. she should first substitute y for t before solving.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
