What I would do is draw out a number line and draw a line above the fractions 5/8 and 3/8, to show the differences. I hope this helped. :)
Answer:
D. 16
Step-by-step explanation:
1. Because these are vertical angles (opposite pair of angles that are formed by intersecting lines), these are congruent. That means (8x-8) = (7x+8).
2. (Solving)
Step 1: Subtract 7x from both sides.
Step 2: Add 8 to both sides.
Step 3: Check if solution is correct.
Therefore, the answer is D. 16.
Hello,
I)
1 solution with multiplicity 2
(2x+1)²=0
II) ANSWER C (-4.41, -1.59)
-3-√2 and -3+√2
III)
y=x²+2x
y=3x+20
==>x²+2x=3x+20
==>x²-x-20=
Δ=1+4*20=81=9²
(x=(1-9)/2=-4 and y= 3*(-4)+20=8 ) or (x=(1+9)/2=5 and y=3*5+20=35)
