Help me pls subtract 28.9 -9.25

19.65

Step-by-step explanation:

you line 28.9 with 9.25 below it and then you subtract it. take it one column at a time.

28.9

-  9.25

the imaginative zero becomes 10 and then the 9 becomes an 8 so 10-5=5 and 8-2=6

then you subtract 9 from 28 and get 19

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

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)
