3/4x-1/2y=12 ax-by=9
what is the value of a/b

Step-by-step explanation:

Hello,

I assume that we are looking for a and b so that

ax - by = 9

<=>

we can notice that 12 = 4 * 3

so we need to multiply by 3 and divide by 4 to get 9 from 12

Then, we can identify a and b

Then

hope this helps

answ9x x 3=

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
