Answer:

x<2

Step-by-step explanation:

Let's solve your inequality step-by-step.

2x−1<3

Step 1: Add 1 to both sides.

2x−1+1<3+1

2x<4

Step 2: Divide both sides by 2.

2x/ 2 < 4/ 2

x<2

Answer:

1) The straight line on the graph below intercepts the two coordinate axes. The point where the line crosses the x-axis is called the [x-intercept]. The [y-intercept] is the point where the line crosses the y-axis. Notice that the y-intercept occurs where x = 0, and the x-intercept occurs where y = 0.

2) There's another important value associated with graphing a line on the coordinate plane. It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." ... This point will always have an x coordinate of zero.

Answer: 4*sqrt(66)

This is the same as saying $4\sqrt{66}$

===========================================================

Explanation:

x = length of segment BD

Because BD is an altitude of triangle ABC, this means the triangle is split into two smaller right triangles which are similar to the original. All three right triangles are similar to one another.

What this leads to is the proportion

CD/BD = BD/AD

Apply substitution and solve for x.

24/x = x/44

24*44 = x*x .... cross multiply

1056 = x^2

x = sqrt(1056)

x = sqrt(16*66)

x = sqrt(16)*sqrt(66)

x = 4*sqrt(66)

Notice how I factored 1056 in such a way that I pulled out the largest perfect square factor (16). Then I used the rule $\sqrt{x*y} = \sqrt{x}*\sqrt{y}
$ to break up the root.
