Determine whether the line Upper L 1L1 whose equation is yequals=5 x minus 95x−9 and the line Upper L 2L2 whose equation is yequals=one fifth x plus 6 1 5x+6 are parallel, perpendicular, or neither.

Neither

Step-by-step explanation:

Let and be the gradients of two lines.

Consider the given lines whose equation is given as y=5x-9 and the line whose equation is given as .

To make a comparison, ensure that the lines are in the slope-intercept form y=mx+c.

In y=5x-9, =5

In , , =

Their product = 1,

Therefore the lines are neither parallel nor perpendicular.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

thus, the first answer choice, y = sec x, is the correct one
