The age of Sydney is 25 years old

<u>Solution:</u>

Given that Devaughn is 7 years older than Sydney

The sum of their ages is 57

Let the age of Sydney be "x"

Then according to given information,

Age of Devaughn = x + 7

Now, Sum of Sydney age and Devaughn age = 57

Substituting the values we get,

x + x + 7 = 57

2x + 7 = 57

2x = 57 - 7

2x = 50

x = 25

"x" represents age of Sydney. Hence Sydney's age is 25 years old

Line CD passes through points C(3, -5) and D(6, 0) . what is the equation of the line CD in standard form?​
Kazeer [188]

Answer:

Option 2: 5x - 3y = 30

Step-by-step explanation:

Step 1: Find slope

(0-(-5))/(6-3) = 5/3

Step 2: Find <em>b</em>

y = 5/3x + b

0 = 5/3(6) + b

b = -10

Step 3: Write in slope-intercept form

y = 5/3x - 10

Step 4: Move x over

-5/3x + y = -10

Step 5: Multiply by -3 on both sides

5x - 3y = 30

And we have our final answer!
