Answer:

x = 5

Step-by-step explanation:

Given that,

63:(5x-3x-1)=21:3\\\\or\\\\\dfrac{63}{(5x-3x-1)}=\dfrac{21}{3}\\\\\dfrac{63}{(2x-1)}=7

Cross multiplying both sides,

63=7(2x-1)\\\\9=2x-1

Taking like terms together,

10=2x\\\\x=5

So, the value of x is equal to 5.

Find the slope and the equation please<br><br>and step by step PLEASE.​
Svetllana [295]

Answer:

y = \frac{-4}{5}x + 1

Step-by-step explanation:

Slope is rise over run, or the vertical progression over the horizontal progression.

Your example has a line that heads downwards, so we know that the slope is negative. If we count the squares, the "rise" is down by 4. We count the squares going horizontally and there are 5. So, your slope is \frac{-4}{5}.

The other half of the equation is the y-intercept, or where the line crosses the y axis. It appears to be at (0 , 1), so we can say that your y-intercept is 1.
