Solve for x. x-2/4 - x+3/3 = -2

1 answer:

7 0

The LCD is 12. Thus, your

(x-2)/4 - (x+3)/3 = -2 becomes 12((x-2)/4 - (x+3)/3 = -2), or

3(x-2) - 4(x+3) = -36

Then 3x - 6 - 4x - 12 = -36. Combining like terms,

-x = -36 + 18, or -x = -18, or x = 18.

Check this result by subbing 18 for x in the given equation.

Please note: You must use parentheses here as indicated to eliminate any ambiguity about order of operations and what divides into what.

Graph the line with slope 2 5 and y -intercept − 7 .

tia_tia [17]

Answer:

See attachment

Step-by-step explanation:

We want to graph the line with slope

$m = \frac{2}{5}$

and y-intercept ,

$b = - 7$

The equation of this line is

$y = \frac{2}{5}x - 7$

Starting at -7 on the y-axis, we run 5 units and rise 2 units right.

Then draw a line through the y intercept and the new point

The graph is shown in the attachment.

Can anyone help me with dis

dolphi86 [110]

Answer:

Slope is 2.

Step-by-step explanation:

So to find slope, we need to take the change in the y value, and the change in the x value, and then divide them. This may be confusing, so here is just 3 formulas in 3 seperate steps that we use to find it:

Step 1 - $x_2-x_1=change_.in_.x$

Step 2 - $y_2-y_1=Change_.in_.y$

Step 3 - $\frac{Change_. in_. y}{Change_.in_.x}=slope$

So lets start by doing step one.

All we need is to look for two x values. Lets use 5 and 6:

6-5=1

So 1 is our change of x. This is our 1st step.

Next we can use 2 y values, note that these should be the 2 y values that go wiht the x values above. So this means we have to use -3 and -1:

-1-(-3) = 2

So 2 is our change in y. This is our 2nd step.

Now lets plug this into:

$\frac{Change_. in_. y}{Change_.in_.x}=slope$ :

$\frac{2}{1} = 2$

So our slope is 2. Completing our 3rd and final step.

Hope this helps!

The price of a game that’s been discounted 18% OFF ITS list price (x)

marta [7]

First you convert the percentage into a decimal. 18% to 0.18, then you multiply that decimal to the price of the item being discounted and bam, you have your price.
