Mama L [17]3 years ago

Answer:

{x,y} = {25/9,23/9}

Step-by-step explanation:

// Solve equation [2] for the variable  x  

 

 [2]    x = -4y + 13

// Plug this in for variable  x  in equation [1]

  [1]    5•(-4y+13) + 2y = 19

  [1]     - 18y = -46

// Solve equation [1] for the variable  y  

  [1]    18y = 46  

  [1]    y = 23/9  

// By now we know this much :

   x = -4y+13

   y = 23/9

// Use the  y  value to solve for  x

Help? which one is it
Ierofanga [76]

Here's the solution,

The given figure is of a parallelogram,

and we know that opposite sides of a parallelogram are equal, so

=》

y + 19 = 2y

=》

19 = 2y - y

=》

y = 19

and,

=》

2x - 8 = x + 16

=》

2x - x = 16 + 8

=》

x = 24

hence, the values are :

x = 24

y = 19

Cally wants to coat her driveway with a winter sealer. Her driveway is 18 feet long and shaped like a trapezoid. At the garage d
stellarik [79]

Answer:

Amount of Winter sealer for 2 coats[in square feet] = 576 square feet

Step-by-step explanation:

Given:

Length of drive way at garage door = 12 feet

Length of drive way at street = 20 feet

Length of total driveway = 18 feet

Find:

Amount of Winter sealer for 2 coats[in square feet]

Computation:

Amount of Winter sealer for 2 coats[in square feet] = 2[Area of trapezoid]

Amount of Winter sealer for 2 coats[in square feet] = 2[(1/2)(Sum of parallel side)(Height)]

Amount of Winter sealer for 2 coats[in square feet] = 2[(1/2)(12 + 20)(18)]

Amount of Winter sealer for 2 coats[in square feet] = 2[(1/2)(32)(18)]

Amount of Winter sealer for 2 coats[in square feet] = 32 x 18

Amount of Winter sealer for 2 coats[in square feet] = 576 square feet

trasher [3.6K]

Solution

write the division as a fraction = 12y^4-4y^3 - 6y^2 + 36y - 22 over y-3 multiplied by r over y-3

r ×(2y^4 - 4y^3- 16y^2 + 36y- 22) over (y-3)^2

2ry^4 - 4ry^3 - 16ry^2 + 36ry - 22r over (y-3)^2
