Evaluate 17s^2 + 32s +180

dezoksy [38]

Answer: 66s + 180

How:

17 s ^ { 1 } 2 + 32 s + 180
Calculate s to the power of 1 and get s.

17s\times 2+32s+180
Multiply 17 and 2 to get 34.

34s+32s+180
Combine 34s and 32s to get 66s.

Final answer should be 66s + 180

Find the slope of a line parallel to y=-2/5x + 4/5

nydimaria [60]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have to, if two lines are parallel then their slopes are equal.

Given the line $y = - \frac {2} {5} x + \frac {4} {5}$ , with slope $m_ {1} = - \frac {2} {5}$ . A parallel line will have slope $m_ {2} = - \frac {2} {5}$ and its equation will be of the form:

$y = - \frac {2} {5} + b$

Answer:

A line parallel to the given line will have slope $m = - \frac {2} {5}$
