Answer:

y =  -  \frac{4}{5} x + 2 \frac{3}{5}

Step-by-step explanation:

To solve for y, we have to arrive at the equation of y= ____.

4x + 5y = 13

<em>-4x</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

5y = - 4x + 13

<em>Divide</em><em> </em><em>by</em><em> </em><em>5</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

<em>y =  -  \frac{4}{5} x +  \frac{13}{5}  \\ y =  -  \frac{4}{5} x + 2 \frac{3}{5}</em>

Nth sequence term question
SSSSS [86.1K]
One example is when n is 11. 11^2 + 4 = 125. 11 is odd but the 11th term of the sequence, 125, is not prime because 125 is divisible by 5 and 25.

-3r + 7 - 3r - 12 in simplest form
Akimi4 [234]
Since the co-efficient or "r" is "-3" and "-3", it will simplify to "-6" as -3-3= -6.
then the two constant terms with are "7" and "-12" will simplify to "-5" as 7-12=-5. therefore, the simplest form is -6r -5

hope it helped!
