Answer:

All values of X is the solution.

Step-by-step explanation:

<em>All values of X is the solution.</em>

Solving the equation you get x<1 and x >-3/2 (which translates into x< -3/2 because you have to flip the sign when negative.

Graphing that gets you to the point where you can see that both lines are on the same space (I can't really show it to you, I hope you understand)

Meaning all values of x are the solution.

:) hope this helps!

Isolate the x in both cases. What you do to one side, you do to the other.

11x + 4 < 15

Subtract 4 from both sides

11x + 4 (-4) < 15 (-4)

11x < 11

isolate the x, divide 11 from both sides

11x/11 < 11/11

x< 1

x < 1 is your answer for the first one

Again, isolate the x.

12x - 7 > -25

Add 7 to both sides

12x - 7 (+7) > -25 (+7)

12x > -18

Isolate the x, divide 12 from both sides

12x/12 > -18/12

x > -1.5 is your answer for the second one.

Komok [63]

Answer:

Write the written problem into an equation to get:

3x +2 = 5x -4

To solve:

Add 4 to each side:

3x+6 = 5x

Subtract 3x from each side:

2x = 6

Divide both sides by 2:

x = 6/2

x = 3

If the diameter of the semicircle is 1.7 centimeters, what is the circumference of the semicircle?

spin [16.1K]

The formula for circumference is $C=2 \pi r$ or $C= \pi d$ . We have a diameter for the semicircle, so let's use the diameter formula. $C= \pi (1.7)$ which is either $C=1.7 \pi$ or C = 5.338 if we multiply pi in as 3.14. BUT this is only half a circle, so we only have half that distance around the outside. Therefore, the circumference of half this circle is 2.669 cm. But we need to add the 24 mm in. 24 mm in centimeters is 2.4 cm. So 2.669 + 2.4 = 5.069

Determine which ordered pair makes the equation true.<br> 2x + y = 11

slavikrds [6]

There is no one ordered pair that makes the equation true, this is a line which has infinitely many ordered pairs that are true...

2x+y=11 subtract 2x from both sides and you have the line in slope intercept form..

y=11-2x

For any real given value of x, you will get one real unique corresponding value for y, resulting in infinitely many unique (x,y) values, points, or ordered pairs, satisfying the given equation.

I assume that you were given "choices" to pick from because of the above reality. So if any of your choices does not satisfy y=11-2x it is not an ordered pair satisfying the equation.

(50 POINTS) Math Inverse Functions please help

Afina-wow [57]

Answer:

See below.

Step-by-step explanation:

An inverse function has the x and y coordinates switched. For example, if a function has point (1, 3), then the inverse function has point (3, 1).

Let's find the ordered pairs of the inverse function. We take all the ordered pairs of the original function:

(1, 3), (7, 4), (8, 6), (9, y)

Now we switch x and y in each ordered pair to come up with the inverse function.

The inverse function has these ordered pairs:

(3, 1), (4, 7), (6, 8), (y, 9)

For a relation to be a function, a value used as an x-coordinate can appear only once.

The last ordered pair is (y, 9). For the inverse relation to be a function, y cannot be 3, 4, or 6.
