Which equation is the inverse of y = 100 – x??

y=1100-
y = 10+ 5x
y = 100+
y=+{X-100

Hey there,

Okay so for inverse equations I use the method in which you switch the variables and solve for y.

So the equation y = 100 - x would look like:

Now we solve for y in this equation:

Since the y is negative and we are solving for a positive we divide by -1 on both sides:

So the inverse of y = 100 - x would have to be -x + 100 = y.

Hope I helped,

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
