Answer:

The sum is equal to $-905,200$

Step-by-step explanation:

we know that

The formula to calculate the sum is equal to

$Sn=n\frac{(a1+an)}{2}$

In this problem

$n=775$ -----> number of terms

a1 is the first term

$a1=(-3(1)-4)=-7$

an is the last term

$an=(-3(775)-4)=-2,329$

substitute

$Sn=775\frac{(-7-2,329)}{2}=-905,200$

Answer:

$\large\boxed{x=3,\ y=0\to(3,\ 0)}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}2x+3y=6&(1)\\x=-2y+3&(2)\end{array}\right\\\\\text{Substitute (2) to (1):}\\\\2(-2y+3)+3y=6\qquad\text{use distributive property}\\\\(2)(-2y)+(2)(3)+3y=6\\\\-4y+6+3y=6\qquad\text{subtract 6 from both sides}\\\\-y=0\to\boxed{y=0}\\\\\text{Put the value of y to (2):}\\\\x=-2(0)+3\\\\x=0+3\\\\\boxed{x=3}$
