Find an equation for the line in the form ax + by c. where a. b. and c are integers with no factor common to all three and a 20. through (1. -6), perpendicular to x + y = 2 the equation of the line is (type an equation)

The standard form of required line is x-y=7.

Step-by-step explanation:

The standard form of a line is

Where, a,b,c are integers with no factor common to all three and a≥0.

The give equation of line is

Here a=1 and b=1.

The slope of a standard line is

The product of slops of two perpendicular lines is -1.

The slope of required line is 1.

The point slope form of a line is

Where, m is slope.

The slope of required line is 1 and it passes through the point (1,-6). So, the equation of required line is

Add 1 on each side.

Subtract y from both the sides.

Therefore the standard form of required line is x-y=7.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
