PLEASE HELP! [99 POINTS] !! SERIOUS ANSWERS ONLY !!!
umka21 [38]
Hello!

We can find out our answer by plugging in the point (1,1) to see which equation works.

y=1.4(1.2)≠1
y=1.2≠1
y=0.5+0.3≠1
y=0.2+1.2≠1

As you can see, none of these answers are correct. You could make the last equation true by switching 0.2 to -0.2. It may have been a typo, so I would say the best answer is D.

I hope this helps!

If x=1 find the value of x2 +2x + 1<br><br>​
Nataly [62]

Hey there!

x^2 + 2x + 1

= 1^2 + 2(1) + 1

= 1 * 1 + 2 + 1

= 1 + 2 + 1

= 3 + 1

= 4

Therefore, your answer is: 4

Good luck on your assignment and enjoy your day!
