Answer:

d

Step-by-step explanation:

you have to foil in situations like these, getting you

Solve the following system of equations: <br>y=2x + 1 <br>y = -x+4<br><br>x= ?<br>y=?​
patriot [66]

Answer:

x= 1, y=3

Step-by-step explanation:

y= 2x +1

y= -x +4

Those two equation are in a system that means they need to be true in the same time. Just like I would say look for a car that is red and is a truck in this case we look for x and y is true that y = 2x+1 and is true that y= =x+4.

so y= 2x+1 but y is -x+4 so substitute

-x+4 = 2x +1,  add x on both sides

4= 2x+x +1, subtract 1 from both sides

4-1 = 2x +x, combine like terms

3 = 3x , divide both sides by 3

x=1

if x=1 we substitute in y= -1 +4 = 3

How do you write the equation of a line (in slope intercept form) with three given points?​
Mrrafil [7]

With even just two points, you can find the equation of a line in slope-intercept form.

Slope-intercept form: y=mx+b where m is the slope and b is the y-intercept

<u>1) Solve for the slope (</u>m<u>)</u>

The equation to solve for the slope is m=\frac{y_2-y_1}{x_2-x_1} when the two points are (x_1,y_1) and (x_2,y_2). Plug the coordinates of these points into the equation and solve for m.

Then, plug m into y=mx+b.

<u>1) Solve for the y-intercept (</u>b<u>)</u>

Then, take any of the given points and plug it into y=mx+b along with the slope. Isolate b to get the y-intercept. Then, plug both m and b back into y=mx+b to get your final equation.

I hope this helps!

-1.398 = 2.2 + n/-5.53<br> Does this look good so far? <br> -1398 = 2200 + n/5530 - 2200
insens350 [35]

Answer:

  n = 19.89694

Step-by-step explanation:

You can work the problem using decimal numbers. There is no need to convert everything to integers. Trying to do so just gets you in trouble.

Subtract 2.2 from both sides:

  -1.398 -2.200 = n/-5.53

  -3.598 = n/-5.53

Now, multiply both sides by -5.53:

  (-5.53)(-3.598) = n = 19.89694

_____

The one rule that cannot be violated in algebra is that <em>you must do the same thing to both sides of the equation</em>.

_____

Your "solution" so far has a couple of errors. The first is that you have apparently multiplied all of the numbers by 1000. Unfortunately, when you multiply a denominator by 1000, it is the same as dividing by 1000. So, you have multiplied the left side by 1000, multiplied one term on the right by 1000 and divided another term on the right by 1000. This turns the equation into something different than what you started with, and will give a wrong answer.

The second error is that you have subtracted 2200 only from the right side. This, too, will turn the equation into something different than what you started with, and will give a wrong answer.

If Gabby wants to buy a t-shirt for $35.99 but she has a discount for 10% off, how much is her final cost?
Leno4ka [110]

Answer:

It's $32.39.

Step-by-step explanation:

35.99 - 35.99*10% =

=35.99 - 35.99*0.1

=35.99 - 3.599

=32.391

32.391 is close to 32.39 so we will round it to that number.

The answer is $32.39.
