What is the error in the equation

dimulka [17.4K]

Answer:

The fifth line contains the error.

Step-by-step explanation:

Line 1 is the equation.

Lines 2, 3, and 4 are correct.

The error is in the 5th line.

The square root of a negative number is not a real number, so if this problem is solved only with real numbers, there is no solution.

If imaginary numbers are allowed, then the last line should read:

$x = \pm\dfrac{i\sqrt{11}}{2}$

Andrea's Sequoia gets 12 miles per gallon while driving in the city, and 20 miles per gallon while on the highway. The last time

Oxana [17]

Answer:

60miles

Step-by-step explanation:

if they drove x miles in the city and y miles on the highway then you know that

x + y = 280

x/12 + y/20 = 16

x + 12y/20 = 16*12 = 192

8y/20 = 88

y = 220

x = 280-y = 280-220 = 60

Solve the system using elimination.

scZoUnD [109]

Answer:

y=50 and x=-173/2

Step-by-step explanation:

52-2y=-48

∴-2y=-100

y=50

and 2x+3y=-23

y=50→(1)

2x+3y=-23→(2)

Putting y=50 in equation (2), we get

⇒2x+3y=-23

⇒2x+3(50)=-23

⇒2x+150=-23

⇒2x=-23-150

⇒2x=-173

⇒x=-173/2

∴y=50 and x=-173/2
