X = t +4
y = t^2
Rewrite the first equation:
x = t+4
Subtract 4 from each side:
t = x-4
Replace t in the 2nd equation with the rewritten equation:
y = x-4^2
Rewrite x-4^2 as (x-4)(x-4)
Use FOIL to get y = x^2-8x+16
The answer is D.
About 260 because 202 plus 57 equals 259 and that'll round to 260

Answer: There are 32 cards left to be signed
Step-by-step explanation:
Hi, the correct question is:
<em>The Smiths are sending out a batch of holiday cards. Emily signed 2/5 of the cards. Then Josh signed 1/9 of the remaining cards. Tatiana signed 20% of what Josh had left. If there were 75 cards in all, how many cards are left to be signed?
</em>
So, to answer this question:
Emily signed 2/5: so, we have to multiply the number of cards (75) by the amount that she signed:
Then, we subtract the result to the total amount of cards:
- 75-30 =45 cards left to be signed
Repeating the process with Josh (now the total number of cards is 45)
And finally we repeat the process with Tatiana ( using the decimal form of 20% ⇒ 20/100= 0.2)
- 40x 0.2=8
- 40-8 = 32 cards left to be signed

y = -1/2 x - 2
