-12 x (1/3)? what is this equal to!

Answer:

-4

Step-by-step explanation:

-12 times 1/3.

It's pretty much just -12x1, then divided by 3.

-12x1 is equal to -12.

Your equation is now simplified, making it easier to solve.

Your equation is: \frac{-12}{3}

-12 divided by 3 is -4, because when a negative number is divided (or multiplied) by a positive number, the quotient (or product) is negative.

-12 x (1/3) = -12/3 = -4.

Switch the second equation to equal y so...
y=-2x-3
then plug in for y in the first equation
2x+4(-2x-3)=6
2x-8x-12=6
-6x=18
x=-3
now plug in for y
2(-3)+y=-3
-6+y=-3
y=3

3. A regular pentagon has a perimeter of 10x + 15. What is the length of che side?
Ivan

Answer:

C

Step-by-step explanation:

A pentagon has 5 sides. Given that it is a regular pentagon, these 5 sides are equal.

The perimeter is the total length of all the sides of the pentagon. Since these 5 sides are all equal, we can divide the perimeter by 5 to obtain the length of a side of the pentagon.

Perimeter= 10x +15

Length of each side

= (10x +15) ÷5

= 2x +3

Write the slope-intercept form of the equation of each line​
Vera_Pavlovna [14]

First let's talk about the blue line.

You can see its rising so its slope is certainly positive. But by how much is it rising? You can observe that each unit it rises it goes 1 forward and 1 up so its slope is the ratio of 1 up and 1 forward which is just 1.

We have thusly,

y=x+n

Now look at where blue line intercepts y-axis, -1. That is our n.

So the blue line has the equation of,

y=x-1

Next the black lines. The black lines are axes so their equations are a bit different.

First let's deal with x-axis, does it have slope? Yes but it is 0. The x-axis is still, not rising nor falling. Where does x-axis intercept y-axis? At 0. So the equation would be,

y=0x+0=0

Now we have y-axis. Does y axis have a slope? Yes but it is \infty. The y-axis rises infinitely in no run. Where does it intercept y-axis? Everywhere! So what should the equation be? What if we ask where does y-axis intercept x-axis and write its equation in terms of x. Y-axis intercepts x-axis at 0 which means its equation is,

x=0

That is, every point of a form (0,a) lies on y-axis.

Hope this helps :)
