3x + 2y = -26 ........(1)

2x - 6y = -10........(2)

Multiplying (1) by 3

= 9x + 6y = -26

Adding (1) and (2)

= 9x + 6y = -78

= 2x - 6y = -10 (+)

---------------------------

11x = - 88

x = -8

Substituting x in (2)

-16 - 6y = -10

-6y = 6

y = -1

Write the equation of a line parallel to y=3

goldenfox [79]

The line y=3 is a horizontal line, and a horizontal line has a slope of zero. The only lines parallel to a horizontal line are other horizontal lines. Therefore, there is no slope. The slope is the coefficient of x in the slope-intercept form: y = mx + b. m stands for the slope, and b is the y-intercept.

How does finding the square root of a number compare to finding the cube root of a number?

Setler79 [48]

Answer:

See explanation below

Step-by-step explanation:

To find the principal square root of a number, we the number with an index of 2. The base then become the principal square root.

In the same way, we find the cube root of a number by writing the number with an index of 3 and the base becomes the cube root of the given number.

For instance:

$64=8^2\implies 8=\sqrt{64}$
