Thus, the option C is the correct option.

How to find one solution of equation?

If the equation given a unique and single value of variable after solving then the equation is said one solution equation.

Such equation gives exactly one solution.

Given information-

To find the equation we have to solve each equation one by one.

A)The equation given in the problem is,

[tex]-7x+2&=-3(x-3)-4x-7\\[/tex]

Solve it further,

[tex]-7x+2&=-3x+9-4x-7\\-7x+2&=-7x+2\\.\;\;\;\;\;\;\;\;\;\;\;0=0[/tex]

Thus this equation has no solution. Hence the option A is the incorrect option.

B)The equation given in the problem is,

[tex]14x&=7(2x+2)[/tex]

Solve it further,

[tex]14x&=14x+14\\.\;\;\;0=14[/tex]

Thus this equation has no solution. Hence the option B is the incorrect option.

C)The equation given in the problem is,

[tex]5x+3=-2(2x+3)[/tex]

Solve it further,

[tex]5x+3=-(4x+6)\\5x+3=-4x-6[/tex]

Bring the same variable terms one side.

[tex]5x+4x=-6-3\\9x=-9\\x=-1[/tex]

As the expression of equation gives the value of variable which is -1.Thus this equation has one solution.

Hence the option C is the correct option.

D)The equation given in the problem is,

[tex]3(4x+2)-9=12x-3[/tex]

Solve it further,

[tex]12x+6-9=12x-3\\2x-3=12x-3\\.\;\;\;\;\;\;\;0=0[/tex]

Thus, this equation does not has one solution.

Hence the option D is the incorrect option.

Hence the equation which has only one solution are,

[tex]5x+3=-2(2x+3)[/tex]

Thus, the option C is the correct option.

What is an equation of the line that passes through the points (0, 3) and (5, -3)?

Answers

Answer:

y = -6/5x + 3

Step-by-step explanation:

y2 - y1 / x2 - x1

-3 - 3/ 5 - 0

= -6/5

To find the y-intercept, you need to plug the coordinates into the equation,

y = -6/5x + b

3 = -6/5(0) + b

3 = 0 + b

b = 3

The equation is y = -6/5x + 3

Answer:

co interior angle plz take my and

Answer:

1) Alternate exterior

2) alternate interior

3) consecutive interior angles

Alright so here’s a trick

Alternate already means different sides so look for that.

Interior angles are all the angles inside the two parllel lines.

Exterior angles are all angles out side the two parralel lines.

No matter what if its alternative interior or exterior, it should make a perfect

“/“ or back slash.

Consecutive is on the same side.

Corresponing is also on the same side but it has 1 exterior and 1 interior

Answer:

Airplane goes 550 mph

Bike goes 9 mph

Ship goes 27 mph

Step-by-step explanation:

The airplane goes 1,925 every 3.5 hours

Divide 1925 by 3.5

1925/3.5 = 550mph

Do the same thing with the bike’s numbers:

45/5 = 9

So 9mph

And again with the ship:

432/16 = 27

It also says its three times as fast as the bike so:

9 x 3 = 27

So the ship goes 27 mph
