2-5 x 1/2 = 0.2 (Length x Width)
Answer:
-43K+17
Step-by-step explanation:
(–9k3 + 12k2 + 9) – (10k3 + 3k2 + 4k – 8)
-9.3=-27 10.3=30
12.2=24 3.2=6
=(-27k+24k+9) - (30k+6k+4k-8)
COLLECT LIKE TERMS
=(-3k+9) - (40K-8)
= -3k+9-40k+8
= -43k+17
Hello!
We can put the x values in and see if we get y
Option 1:
Set A: y = 4x - 2
Do the first values
y = 4(-1) - 2
y = -4 - 2
y = -6
Look at the next one to be sure
y = 4(1) - 2
y = 4 - 2
y = 2
So the set A equation is correct we can look at set be now
y = x + 4
y = -5 + 4
y = -1
Try the next one to be sure
y = -2 + 4
y = 2
So the set B equation is also correct
The answer is the first one
Hope this helps!
You will turn 0.30 into a fraction, an when you do, you get 3/10, so that is your answer.
Option A, there seems to be no error
