Solve the equation |x-2|-3=0 first by finding the zeros of<br> y=|x-2|-3 and then algebraically.
tino4ka555 [31]

Answer:

The solution of given equation are -1 and 5.

Step-by-step explanation:

The given equation is

|x-2|-3=0

We need to solve the above equation by finding the zeros of

y=|x-2|-3

The vertex form of an absolute function is

y=a|x-h|+k

where, a is constant and (h,k) is vertex.

Here, h=2, k=-3. So vertex of the function is (2,-3).

The table of values is

   x           y

   0         -1

   2         -3

   4         -1

Plot these points on a coordinate plane and draw a V-shaped curve with vertex at (2,-3).

From the given graph it is clear that the graph intersect x-axis at -1 and 5. So, zeroes of the function y=|x-2|-3 are -1 and 5.

Therefore the solution of given equation are -1 and 5.

Now solve the given equation algebraically.

|x-2|-3=0

Add 3 on both sides.

|x-2|=3

x-2=\pm 3

Add 2 on both sides.

x=\pm 3+2

x=3+2 and x=-3+2

x=5 and x=-1

Therefore the solution of given equation are -1 and 5.

A boat can travel 333 miles on 37 gallons of gasoline. How much gasoline will it need to go 486 miles?
pochemuha
<h3>Answer:  54 gallons</h3>

Work Shown:

(distance)/(gallons used) = (distance)/(gallons used)

(333 miles)/(37 gallons) = (486 miles)/(x gallons)

333/37 = 486/x

333x = 37*486 .... cross multiplication

333x = 17,982

x = (17,982)/333

x = 54 gallons

You need 54 gallons to travel 486 miles.
