Step-by-step explanation:

simplify both sides of the equation

add 4x to both sides subtract 3 from both sides. Divide both sides by 9 and that's it

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

The equation which has only one solution are,

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

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.

[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.

[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.

[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.

[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.

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:

12% decrease

Step-by-step explanation:

So you have to do V2 aka 132-150 to get -18/150. Then, you multiply it by 100 to get 0.12. they you multiply 0.12 by 100 and you get -12% change, or 12% decrease.

Answer:

The answer is 5

Step-by-step explanation:

5 × 5 is 25, so the square root is going to be 5.

Answer:

Both f(x) and g(x) have the same output value at x = 5

Step-by-step explanation:

When we are writing a function, while x gives the input value, writings like f(x), g(x) or h(x) will represent the output values of the input value of x

Now, looking at the relation, we are told that the value of f(x) = g(x) at x = 5

What this mean is that at x = 5; the output value of g(x) is the same as the output value of f(x)

Hence, we can conclude that both functions have the same output value at the given input value of x = 5

Answer:

D) Both f(x) and g(x) have the same output value at x = 5.
