Ok so this question:
y + 1 = - ( x - 2 ) (distribute the negative inside the parenthesis)
y + 1 = -x + 2 (substitute the y= -1)
-1 + 1 = -x + 2
0 = -x + 2 (take two to the other side)
-2 = -x (divide the negative away from x)
2 = x
Answer:
x=36
y=6
Step-by-step explanation:
Let the numbers be x and y
Condition 1
x=6y ----------(1)
Condition 2
x-y=30 ------------(2)
Putting 1 in 2
6y-y=30
5y=30
Dividing both sides by 5
y=6
Now
Putting y=6 in 1
We get
x=6(6)
x=36
The correct answers are: 1/2, 2 and -2.
To get this, factor f(x)
f(x)=2x^3-x^2-8x+4
f(x)= (2x^3-x^2) - (8x -4)
f(x)= (2x-1)(x^2) + (2x-1)(-4)
f(x)= (2x-1)(x^2-4)
f(x)= (2x-1)(x-2)(x+2)
2x-1=0
2x=1
x=1/2
x-2=0
x=2
x+2=0
x=-2
Option 4 is the answer.
50+30
=80
10(5+3)
= 10×8
=80
Hence, the correct option => 10(5+3)
Hope it helps!
