5x-3y=11
So first you need to switch -3y with 11 first because the the formula is y=mx+c
So, 5x -11= 3y
Now make y as the subject: 3y= 5x-11
Now divide both of the numbers by 3 to make it y=mx+c
So, y=3/5x-11
y=1.67x-3.67

Now try the another one by yourself by using my steps and remember that when you are switching the side. suppose if 3=5x if I will switch the side for this it will move from positive to negative so it will be -5x=-3.
If you want to switch from negative to positive it will be 3=5x (this is just an example)

I hope you understood my explanation. Thank me later.

6.5 + (−2) + 10.5 I could probably do this but its kind of hard to understand. Explain?
elena-s [515]
Hello! Let's work this problem from left to right to make things a bit easier ;)

6.5+(-2) is the same as 6.5-2, since adding a negative is the same as subtracting a positive. 6.5-2=4.5

Now, we have to add 10.5 to 4.5, which gives us the grand total of 15. I hope this helped! Let me know if you need anything else!

Bring the fraction a/a−4 to a denominator of 16−a^2<br><br> really do appreciate this thx
RSB [31]

Answer:

-a(a+4)/(16 - a²)

Step-by-step explanation:

            a/(a - 4)                  Multiply by (a + 4)/(a + 4)

= a(a + 4)/[(a – 4)(a + 4)]     Multiply the denominatorator terms

= a(a + 4)/(a² - 16)               Multiply by -1/(-1)

= -a(a+4)/(-a² + 16)              Reorder terms in denominator

= -a(a+4)/(16 - a²)

PLEASE HELP ME, ILL BRAINLIEST YOU ill give u 30 points if you help
lisov135 [29]

Answer:

x = 58

y = 90

Step-by-step explanation:

  • This is a rhombus becuase it a quadralterial and it has four right triangles, and it diagonals bisect each others so it cant be a trapezoid, and paralleolgram. and it doesnt have four right corner angles so it cant be a square or rectangle or kite.

A rhombus inner angle measure is 90 degrees.

So

y = 90

This means the upper left angle of the top triangle measure is 58 becuase triangle interior theorem.

Since a rhombus bisects angles, angle x measure 58.
