False solution; [1⅐, -3 3⁄7]

Step-by-step explanation:

{x - 2y = 8

{4x - y = 8

-¼[4x - y = 8]

{x - 2y = 8

{-x + ¼y = -2 >> New Equation

____________

-1¾y = 6

y = -3 3⁄7 [Plug this back into both equations to get the x-coordinate of 1⅐]; 1⅐ = x

What is the slope of a line that is perpendicular to the line whose equation is 8y−5x=11?
ElenaW [278]

9514 1404 393

Answer:

  -8/5

Step-by-step explanation:

When you solve for y, the slope of the line is the x-coefficient. For the given line, that is ...

  8y = 5x +11 . . . . . add 5x

  y = 5/8x +11/8 . . . . divide by 8

The given line has a slope of 5/8. The perpendicular line will have a slope that is the opposite of the reciprocal of this:

  -1/(5/8) = -8/5 . . . . slope of perpendicular line

In 2000, Greenville had a population of 63,205 people. Greenville’s population increased by 2500 people each year. In 2000, Spri
Llana [10]

Answer:

year 6.6025 if there is no typo in your question and numbers are right.

Step-by-step explanation:

G = 63205 + 2500x

S = 50000 + 4500x

since 9% of 50000 = 0.09(50000) = 4500

find when G = S

63205 + 2500x = 50000 + 4500x

subtract both sides by 2500x to move x terms to the right

63205 = 50000 + 2000x

subtract both sides by 50000 to move the number to the left, so we can get like terms on each side

13205 = 2000x

divide both sides by 2000

x = 6.6025
