The answer
<span>to eliminate t from the parametric equations x=t^2+3 and y=4t
we have t²= x-3, and then t= sqrt(x-3), but we know that y=4t, which implies t=y/4. We only substitute the value of t by y/4, so </span>t= sqrt(x-3) wich is equivalent to y/4=sqrt(x-3), so at last y= 4 sqrt(x-3). t exactly eliminated.
so the true answer is
<span>D)She should first substitute y for t before solving.</span>
Answer:
B
Step-by-step explanation:
B bc if you simplify correctly and bring 27 + 7 and divide that by the quotient, it gives you answer B
Answer:
5 44 32 1 45
Step-by-step explanation:
Answer:
C
The "inverse operation" is just a way of saying "what do you do to isolate the variable". In this case, we isolate y, so we have to move all terms to the right side. To do that, we subtract 12 from each side to there will only be "y" on the left side.
Answer: Gonzo runs 0.435 seconds faster than Kermit.
Step-by-step explanation:
This is just a simple subtraction problem.
To make both numbers even in place value, add a 0 (zero) in the back of 12.35 to make it 12.350.
Then you simply subtract using regrouping methods:
12.350
11.915 -
————
0.435
Now let’s check our answer:
11.915
0.435. +
—————
12.35
As a result, Gonzo ran 0.435 seconds faster than Kermit.
