How many solutions are there to the system of equations graphed below if the lines are parallel

mash [69]

If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

Sorry, this is a general answer. I could not view the graph below...

The larger number is 18 more than twice the smaller. If the sum of the two numbers is 93, find both numbers

Ganezh [65]

Answer:

larger number=18+(2x)

smaller number=x

(18+2x)+x=93

18 +3x=93

3x=93-18

3x=75

x=25

18+2(25)

18+50

larger number =68

smaller number=25

Solve for the vector x + 2a - b in terms of the vectors a and b. (If needed, use BOLD vector form on calcPad Vector menu.) x + 2

nikdorinn [45]

Answer:

x+2a-b=5x+5a-2*3a+2*b

x+2a-b=5x+5a-6a+2b

x+2a-b=5x-a+2b

5x-x=2a-b+a-2b

4x=3a-3b

4 x=3(a-b)

x=3/4(a-b)

The volume of two similar solids are 128 m3

arsen [322]

Answer:

Solution given:

The volume of two similar solids are 128 m³

and 250 m³.

surface area of larger solid is 250m²

let surface area of smaller solid be x.

Since they are similar

$\frac{250}{128} = \frac{250}{x}$

x=128

the surface are of the

smaller solid is 128m²
