Convert to slope-intercept form, y = mx + b.
12 = 4x - 6y
Subtract 4x to both sides:
12 - 4x = -6y
Divide -6 to both sides:
y = 2/3y - 2
Now its in slope-intercept form, y = mx + b, where 'm' is the slope.
So the slope is 2/3.
Ages of Kim and Kevin are 50 and 20 respectively.
<u>Step-by-step explanation:</u>
Step 1:
From given details, form equations. So let present age of Kevin be x.
In 10 years, Age of Kim = 2(x + 10)
5 years ago, Age of Kim = 3(x - 5)
Step 2:
Difference between these two period is 15.
⇒ 2(x + 10) - 3(x - 5) = 15
⇒ 2x + 20 - 3x + 15 = 15
⇒ -x = -20
⇒ x = 20
Step 3:
Calculate Kim's age.
In 10 years, Kim's age = 2(x + 10) = 2 × 30 = 60
So present age of Kim = 60 - 10 = 50
Answer:
a = 18
Step-by-step explanation:
3(x+6)-x = 2x + a
Distribute
3x +18 -x = 2x+a
2x +18 = 2x+a
Subtract 2x from each side
18 = a
