George is twice as old as Edward, and Edward's age exceeds Robert's age by 4 years. If the sum of the three ages is at least 56

marshall27 [118]

Answer:Robert's minimum age is 11 years.

Step-by-step explanation:

Let x represent George's age.

Let y represent Edward's age.

Let z represent Robert's age.

George is twice as old as Edward. It means that

x = 2y

Edward's age exceeds Robert's age by 4 years. It means that

z = y - 4

If the sum of the three ages is at least 56 years, it means that

x + y + z ≥ 56 - - - - - - - - - - 1

Substituting x = 2y and z = y - 4 into equation 1, it becomes

2y + y + y - 4 ≥ 56

4y - 4 ≥ 56

4y ≥ 56 + 4

y ≥ 60/4

y ≥ 15

z = y - 4 = 15 - 4

z ≥ 11

A line passes through the points (-1,-1) and (5,8) which points lie on the same line?

djverab [1.8K]

Answer: all points $(x,y)$ that satisfy $y=\frac{3}{2}x+\frac{1}{2}$

Step-by-step explanation:

The slope of the line is

$\frac{-1-8}{-1-5}=\frac{-9}{-6}=\frac{3}{2}$

So, substituting into point-slope form, the equation is

$y+1=\frac{3}{2}(x+1)\\\\y+1=\frac{3}{2}x+\frac{3}{2}\\\\y=\frac{3}{2}x+\frac{1}{2}$

Therefore, all points $(x,y)$ that satisfy $y=\frac{3}{2}x+\frac{1}{2}$ will lie on the same line.
