-2x < -6
Soloha48 [4]

Answer:

x > 3

Step-by-step explanation:

This is based on the concept 'when a negative number is multiplied to both sides of the inequality, the sign gets reversed. For example, x > - 2 when it is multiplied by - 1, it becomes - x < 2.'

*only when the number is -ve.

Similarly, in this question, multiply both sides by - 1.

2x > 6

x > 6/2

x > 3

For more : take - 5 > - 2, as you know

Note that 5 is actually greater than 2. To make this true we change signs

What is the value of y in the equation 2(3y + 7 + 5) = 196 − 16? (1 point) Group of answer choices 13 14 26 28
Tema [17]

Answer:

Option c) is correct.

The value of y in the given equation is 26 ie., y=26

Step-by-step explanation:

Given equation is

2(3y+7+5)=196-16

Now to the find the value of y in the above equation.

To find y simplify the above equation

2(3y+7+5)=196-16

2(3y+12)=180

Now apply distributive property

6y+24=180

6y=180-24

=\frac{156}{6}

Therefore y=26

Option c) is correct.

The value of y in the given equation is 26 ie., y=26

EXTRA POINTS* how do you graph y = -3x - 9
Andreas93 [3]

Answer:

See Below

Step-by-step explanation:

Ok, your equation is in slope intercept form (y= mx + b), where m is the slope and b is the y intercept.

y = -3x -9

y = mx + b

m = -3

b = -9

Soo, plot the y-intercept first. (-9)=> (0,-9)

Then go down 3 over 1 (do this twice) (in my case, down 9 over 3)  

Then draw the line.
