First, disregard the sign for absolute value and solve for x.
2x - 1 = 3x + 5
2x - 3x = 5 + 1
-x = 6
x = -6
Now, you have to interpret the absolute value. The absolute value of x is always the positive version of whatever the number is. Since x = -6, its absolute value is 6. Therefore, the possible value for x is only one, which is 6.
X^2 - 8x + 13 = 0
subtract 13 from both sides
x^2 - 8x = -13
-8/2 = -4, (-4)^2 = 16, add 16 to both sides
x^2 - 8x + 16 = -13 + 16
factor the left side
(x - 4)^2 = 3
Answer:
x = 6
Step-by-step explanation:
3x + 16 = 34
34 - 16 = 18
3 x ? = 18
3 x (6) = 18
18 + 16 = 34
Hope this helps :D
Answer:
y=-2x+3
Step-by-step explanation:
=(4/7)^3
=(4/7)*(4/7)*(4/7)
=4*4*4 / 7*7*7
=4^3 / 7^3
=64/343
Answer is D.
