Find the x -intercept and the y -intercept. Then use them to graph the line of 6x+2y=-12

Neko [114]

The x intercept is when y=0
6x+0=-12
x=-2, now you have point A with coordinates (-2, 0)
The y intercept is when x=0
0+2y=-12
y=-6, so you have another point with coordinates (0, -6)
Connect those two points, you have your graph. It is a line.

3-^1 x (4 x 6) x 2-^3

xeze [42]

$\huge{ \boxed{ \mathbf{ \blue{Problem:-}}}}$

$\bold{ {3}^{ - 1 \ } (4 \times 6) \times {2}^{ - 3} }$

$\huge{ \boxed{ \bf{ \blue{Solution:-}}}}$

$\bold{ {3}^{ - 1}(4 \times 6) \times {2}^{ - 3} }$

$= \bold{ \frac{1}{3}^{1} (4 \times 6) \times { \frac{1}{2}^{3} } }$

$= \bold{ \frac{1}{3} \times 24 \times \frac{1}{8} }$

$\bold{= 1}$

Which of the following equations have exactly

Anestetic [448]

Answer:

-5x + 12 = –12x – 12

-5x + 12 = 5x + 12

-5x + 12 = 5x – 5

Step-by-step explanation:

First degree equations

A first degree equation has the form

ax + b = 0

There are some special cases where the equation can have one, infinitely many or no solution

If $a\neq 0$ , the equation has exactly one solution

If a=0 and b=0 the equation has infinitely many solutions, because it doesn't matter the value of x, it will always be true that 0=0

If a=0 and $b\neq 0$ the equation has no solution, because it will be equivalent to b=0 and we are saying it's not true. No matter what x is, it's a false statement.

We have been given some equations, we only need to put them in standard form

-5x + 12 = –12x – 12

Rearranging

7x + 24 = 0

It has exactly one solution because a is not zero

.......................

-5x + 12 = 5x + 12

Rearranging

-10x + 0 = 0

It has exactly one solution because a is not zero

.......................

-5x + 12 = 5x – 5

Rearranging

-10x + 17 = 0

It has exactly one solution because a is not zero

.......................

-5x + 12 = -5x – 12

Rearranging

0x + 24 = 0

It has no solution, no matter what the value of x is, it's impossible that 24=0

Answer: These are the equations with exactly one solution

-5x + 12 = –12x – 12

-5x + 12 = 5x + 12

-5x + 12 = 5x – 5
