Answer:
The second option
Step-by-step explanation:
4x - 2 > 6x + 8
add 2 to both sides
4x - 2 + 2 > 6x + 8 + 2
2 cancel -2 and it remains
4x > 6x + 10
Now, subtract 6x from both sides
4x -6x > 6x -6x + 10
it remains
-2x > 10
divide via by -2
x > 10/-2
x < -5
When you multiply or divide by a negative, the inequality sign changes

Answer:
x= 2.5
Step-by-step explanation:
We can use ratios to solve
AB AD
------- = ----------
AC AE
X 5
------- = ----------
x+1 7
Using cross products
7x = 5(x+1)
Distribute
7x = 5x+5
subtract 5x
7x-5x = 5x-5x+5
2x= 5
Divide by 2
2x/2 = 5/2
x = 2.5
Answer:
there's no box so I wouldn't know silly
Answer:
b = 2a + 3
Step-by-step explanation:
Here, we want to write an expression for b in terms of a
Mathematically, the formula for the slope of a line is
m = (y2-y1)/(x2-x1)
m is 2
(x1,y1) = (-1,1)
(x2,y2) = (a,b)
Substituting these values
2 = (b-1)/(a-(-1))
2 = b-1/a + 1
2(a + 1) = b-1
2a + 2 = b- 1
2a + 2 + 1 = b
b = 2a + 3
