If y=-8 and x= -3 what’s x when y= 6

Part 1)

Part 2)

Step-by-step explanation:

Analize two problems

Part 1) If y varies directly with x, and If y=-8 and x= -3 what’s x when y= 6

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

step 1

Find the value of the constant of proportionality k

For x=-3, y=-8

substitute the given values

step 2

Find the linear equation

step 3

Find the value of x when y=6

substitute the value of y in the linear equation

solve for x

simplify

Part 2) If y varies inversely with x, and If y=-8 and x= -3 what’s x when y= 6

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or

step 1

Find the value of the constant of proportionality k

For x=-3, y=-8

substitute the given values

step 2

Find the  equation

step 3

Find the value of x when y=6

substitute the value of y in the equation

solve for x

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
