If (x+28y)/x=50 then what does (y+28x)/y=

17

Step-by-step explanation:

(x+28y)/x =50

Multiply each side by x

(x+28y)/x *x =50*x

x+28y = 50x

Subtract x

x-x+28y = 50x-x

28y = 49x

Divide by y

28y/y = 49x/y

28 = 49 x/y

Divide by 49

28/49 = x/y

We want to find

(y+28x)/y

Rewriting as

y/y +28 (x/y)

1 + 28(x/y)

Replacing x/y with (28/49)

1 + 28(28/49)

1 +28*28/49

1+784/49

1+16

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
