Suppose that Eldi has x years old now :

x + 4 = 3 × ( x - 10 )

x + 4 = 3x - 30

Add both sides 30

x + 4 + 30 = 3x - 30 + 30

x + 34 = 3x

Subtract both sides x

x - x + 34 = 3x - x

34 = 2x

2x = 34

Divide both sides by 2

2x ÷ 2 =34 ÷ 2

x = 17

_____________________________

Thus Eldi is 17 .

What is the equation of the line that passes through the point (-6, -2) and has a slope of 1/6

Levart [38]

<h2>Answer:</h2>

Step 1: Determine b by using the point (-6,-2), the given slope, and the slope intercept formula, y = mx + b.

$y = mx + b\\\\-2 = \frac{1}{6}(-6) + b\\\\-2 = -1 + b\\\\-1 = b$

Step 2: Now that we have b, we can determine the equation of the line.

$y = \frac{1}{6}x -1$

I didn't use + (-1) because b is negative. Therefore you need to change the equation from y = 1/6x + (-1) to y = 1/6x - 1.
