Alan is x like it says
Barry is x-10 because he is 10 years younger than Alan
Kevin is 2x as he is 2 times Alan’s age
Therefore
x+x-10+2x=54
4x-10=54
4x=44
x=11
Alan= 11 years old
Barry is = 1 year old
Kevin is = 22 years old
The equation of the parallel line is y = x + ⇒ 3rd answer
Step-by-step explanation:
Parallel lines has:
- Same slopes
- Different y-intercepts
The slope-intercept form of the equation of a line is y = mx + b, where
- m is the slope of the line and b is the y-intercept
- The formula of m is
∵ Line EF has E (-2 , 5) and F (1 , 3)
∴ = -2 and = 1
∴ = 5 and = 3
- Use the formula of m above to find the slope of line EF
∴
∵ The line is parallel to line EF
∴ Their slopes are equal
∴ The slope of the parallel line is
- Substitute the slope of the line in the form of the equation
∴ y = x + b
- To find b substitute x and y in the equation by the coordinates
of a point on the line
∵ The parallel line passes through point (2 , 6)
∴ x = 2 and y = 6
∴ 6 = (2) + b
∴ 6 = + b
- Add to both sides
∴ = b
∴ y = x +
The equation of the parallel line is y = x +
