For each equation given below, write ONE related equation. a) x + 5 = 18 b) 66x =330
GenaCL600 [577]

Answer:

x = 13 ; x = 5

Step-by-step explanation:

The easiest related equation to get is simply solving for x:

a) x + 5 = 18

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 5 from both sides:

x + 5 (-5) = 18 (-5)

x = 18 - 5

x = 13*

b) 66x = 330

Isolate the variable, x. Divide 66 from both sides of the equation:

(66x)/66 = (330)/66

x = 330/66

x = 5*

*Note: An equation simply is a expression that has an equal sign. This means that as long as there is an equal sign, it counts as an equation.

Match the information on the left with the appropriate equation on the right.
zaharov [31]

Answer:

See attachment below

Step-by-step explanation:

For the first option, we are given m = - 2 / 3, b = 3. This is likely in the point - slope form y = mx + b, where m = slope and b = y - intercept. Thus, the equation of the line in point - slope form given this information, should be y = - 2 / 3x + 3. It seems as if none of the following equations match this form, so let us interchange the equation a bit,

y = - 2 / 3x + 3,

y + 2 / 3x = 3,

2x + 3y = 9 - Option C

_______________________________________________________

Next we are given m = - 3 / 2, and that this line passes through the point ( 4, - 1 ). Substitute m as - 3 / 2, x as 4, y as - 1, knowing point ( 4, - 1 ), into the form y = mx + b - solving for b.

- 1 = ( - 3 / 2 )( 4 ) + b,

b = 5,

Thus the equation in point - slope form should be y = - 3 / 2x + 5. None of the choices match this, so let us again alter the equation,

y = - 3 / 2x + 5,

2y = - 3x + 10,

- 2y = 3x - 10 - Option A

_______________________________________________________

( 6, 3 ) and ( 3, 1 ) is given to lie on this line. The slope of the line should be as follows,

Slope = 3 - 1 / 6 - 3 = 2 / 3

Now let us determine the y - intercept ( b ) by substitute one of the points, say ( 6, 3 ). In this case x = 6, and y = 3,

3 = ( 2 / 3 )( 6 ) + b,

b = - 1,

y = 2 / 3x - 1 = Option D
