Answer:

x = -2

Step-by-step explanation:

x - 5 + 12 + 2x = 4(8 – 11x) + 7(1 + 9x)

x - 5 + 12 + 2x = 32 - 44x + 7 + 63x

x - 5 + 12 + 2x = 32 - 44x + 7 + 63x

x + 2x + 44x - 63x = 32 + 7 + 5 - 12

- 16x = 32

- x = 32 / 16

- x = 2

x = -2

Mariana solved a linear equation and found that it had an infinite number of solutions. Which could have been the final line of
Fofino [41]

Answer:

0=0

Step-by-step explanation:

Well, the linear equation can be expressed as y=ax+b in the solution of linear equations, there 3 main cases can be concluded as final lines. 1st case - the linear equation has no solution (for example, 0*x=5 has no solutions). 2nd case - the linear equation has one solution (for example 4*x=3 where the only one solution is x=0.75) and the 3rd case - the linear equation has infinite number of solutions (for example 0*x=0). So, in our case (3rd case) the last line can be concluded as 0=0.

Answer:

y = - 9.1768x2 + 122.2567x + 14.9091

Step-by-step explanation:

Given the following :

Month (x) Daily Rental Price (y) 1 $154 2 $205 3 $266 4 $358 5 $403 6 $425 7 $437 8 $430 9 $381 10 $285 11 $211 12 $195

Using the online regression equation graphing tool ; The quadratic model obtained in the form,

y = Ax^2 + Bx + C is :

y = - 9.1768x2 + 122.2567x + 14.9091

Attached below is a picture of the quadratic regression curve.
