What is the solution for y=-2/3x -2 and y= -2x+2

1 answer:

7 0

Y=-2/3 x-2
y=-2x+2
We solved this equations system by equalization method.
-2/3 x -2=-2x+2
Least common multiple: 3
-2x-6=-6x+6
-2x+6x=6+6
4x=12
x=12/4=3

y=-2x+2
y=-2(3)+2=-6+2=-4

Solution: x=3; y=-4

To chek:
y=(-2/3)3-2=-4
y=-2(3)+2=-6+2=-4

98. What is the sum of the first 27 terms in the arithmetic series 25 +19+13 + ...?

jeka57 [31]

Answer:

sum of the first 27 terms = -1431

Step-by-step explanation:

<h3>arithmetic series sum of the first n terms formula:</h3>

$s_{n} = \frac{n}{2} (2a + (n - 1)d)$

n = 27 terms

first term, a = 25

common difference, d = 19 - 25 = -6

substitute the values into the formula

$s_{27} = \frac{27}{2} (2(25) + (27 - 1)( - 6))$

$s_{27} = 13.5(50 + 26( - 6))$

$s_{27} = 13.5(50 - 156)$

$s_{27} = 13.5( - 106)$

$s_{27} = - 1431$
