9(n+2)-5n for n = 1/4

Step-by-step explanation:

Replace n with the given value, 1/4

9 (1/4 + 2) - 5×1/4

9×9/4 - 5/4 Do inside the parenthesis

81/4 - 5/4 add the terms

76/4 = 19 this i.s the result

19

Step-by-step explanation:

9(n+2)-5n for n = 1/4

Solve :

9(n+2)-5n

Put value of n

= 9(1/4 + 2) - 5 (1/4)

= 9( (1+8)/ 4 ) - 5/4

= 81 /4 - 5/4

= 81-5/4

= 76/4

= 19

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
