Answer:

b.) Subtracting 5 then dividing both sides by -2

Step-by-step explanation:

Given expression:

⇒ -2x + 5 = 9

To solve this equation, first we need to remove the 5 on the left side. Then divide both sides by -2.

When done so:

⇒ -2x = 9 - 5

⇒ -2x = 4

⇒ -2x/-2 = 4/-2

⇒ x = -2

What would the inverse be?

Find the inverse of f(x)=2x-3.

1) replace "f(x)" with "y."   Then y=2x-3.
2) interchange x and y.  Then x=2y-3.                   x+3
3) solve this result for y.  Then 2y=x+3, or   y=----------------
                                                                                  2
                            -1           -1           x+3                        
4) replace y with f   (x):    f    (x) = ---------
                                                           2

This is the procedure, with the answer given.

Darya [45]
Let’s say that Keenan give Tisha 8 of the 16 strawberries he had. So Tisha kept 4 of the 8 strawberries she got from Keenan and gave the rest to Suvi. The expression could be written like this: 16-8=8-4=4

Jim's speedboat can travel 24 miles upstream against a 4 mph current. In the same amount of time it travels 26 miles
8_murik_8 [283]

Answer:

speed of the boat = 100 mph

Step-by-step explanation:

Let x = speed of the boat

upstream speed = x - 4

downstream speed = x + 4

time = 24/(x - 4) = 26/(x + 4)

Cross multiply:

24(x + 4) = 26(x - 4)

24x + 96 = 26x - 104

104 + 96 = 26x - 24x

200 = 2x

x = 100 mph
