Graph the system of inequalities y<5x-1, y<img src="https://tex.z-dn.net/?f=%20%5Cgeq%20" id="TexFormula1" title=" \geq " alt

zhannawk [14.2K]

The inequalities that are given in this item are given below,
y < 5x - 1
y ≥ -3x +4

We dropped the inequalities sign to solve for the values of x and y for the intersection.
y = 5x - 1
y = 3x + 4

Substituting the y from the first equation to the y of the second equation,
5x - 1 = 3x + 4
2x = 5
x = 5/2

Substituting for y,
y = (5)(5/2) - 1
y = 25/2 - 1 = 11.5

The intersection is (5/2, 11.5)

The solutions of the system of inequalities lie in the 3rd and 4th quadrants.

Find the sum of the summation of 2 i minus 9, from i equals 3 to 10.

amid [387]

Answer:

$\sum_3^{10}(2i-9) =32$

Step-by-step explanation:

First we write the problem in summation notation.

The sum of the summation of 2 i minus 9, from i equals 3 to 10 is:

$\sum_3^{10}(2i-9)$

Now we solve the expression

$\sum_3^{10}(2i-9) = (2(3) -9) + (2(4) -9) + (2(5)- 9) + (2(6) -9) +(2(7) -9)+\\\\(2(8) -9)+ (2(9) -9)+ (2(10) -9)\\\\\\\sum_3^{10}(2i-9) = (6 -9) + (8 -9) + (10- 9) + (12 -9) +(14 -9)+ (16 -9)+\\\\(18 -9)+ (20 -9)\\\\\\\sum_3^{10}(2i-9) = (-3) + (-1) + (1) + (3) +(5)+ (7)+ (9)+ (11)\\\\\\\sum_3^{10}(2i-9) =32$
