Answer: -14
Remove parenthesis to -1-4+(-9)
When there is a “+” in front of an expression in parenthesis, the expression remains the same, so;
-1-4-9 calculate the sum of the negative numbers
-1-4= -5, -5-9= -14

For the given pair of equations, give the slopes of the lines, and then determine whether the two lines are parallel, perpendicu
Nat2105 [25]

Answer/Step-by-step explanation:

Given,

10x - 3y = 3

3x + 10y = 30

Rewrite both equation in slope-intercept form, y = mx + b.

Where, m = slope of the line.

Thus,

✔️10x - 3y = 3

-3y = -10x + 3

y = 10/3x - 1

Slope of this line would be 10/3

✔️3x + 10y = 30

10y = -3x + 30

y = -3/10x + 3

The slope of this line is -³/10.

✔️The two lines are pendivukar to each other because the slope of one is the negative reciprocal of the other.
