Answer: x =9

Step-by-step explanation:

These are corresponding angles, meaning they are equal. (the same angle). Set them equal to each other to solve. 13x+ 3 = 12x +12. Subtract 3 from both sides. 13x = 12x + 9. Subtract 12x from both sides. X = 9

Solve the inequality 2(4x-3)>-3(3)+5x

Sholpan [36]

Answer:

$x > -1\\$

Step by step explanation:

$~~~~~2(4x-3) > -3(3)+5x\\\\\implies 8x-6 > -9+5x\\\\\implies 8x > -9+6+5x\\\\\implies 8x > -3+5x\\\\\implies 8x -5x > -3\\\\\implies 3x > -3\\\\\implies x > -\dfrac 33\\\\\implies x > -1$

If FG=10 and HJ = 10. Which additional facts guarantee that FGHJ is a parallelogram? check all that apply.

Kamila [148]

Yes, if FJ || GH, and also if FG || HJ, since a parallelogram has two pairs of parallel sides.

now, we know FG = HJ = 10, but if it's a parallelogram, then the other two sides must also have the same length, so chances are FJ = GH = 15.

What sort of information can you get from conditional frequencies that you couldn't get by just looking at the relative frequenc

shepuryov [24]

Answer:

<h2>Conditional frequencies offer more specific information to analyse certain data set.</h2>

Step-by-step explanation:

A conditional frequency is a type of relative frequency which involves a condition to be defined.

For example, the conditional frequency of having a house given that the person is female. Notice that this example shows the condition "being female", so the conditional frequency would be all females who own a house.

On the other hand, the relative frequency is just a ratio between the frequency of the data and the total number of data. It's doesn't includes a condition to be defined, that's the difference.

Therefore, conditional frequencies offer more specific information to analyse certain data set.

Anyone that can help me with this?

mrs_skeptik [129]

If a rational function is not continuous, it'll be due to one of two reasons. Either it has a hole, or it has an asymptote. Plug in -5 for x in the denominator of the rational function. What do you get? You get zero in the denominator, meaning the function is undefined at x=-5.

A parallelogram has an area of 81 m² and a base of 9 m. What is the height of the parallelogram?

garri49 [273]

Answer:

9 m

Step-by-step explanation:

Let me just say WHY this is your answer before we solve it!

This is your answer because, if 9x9=81, then what else do you need. To find the area of something, you just need to <u>MULTIPLY!</u>

SO, to find the area of this, we just have to divide 81 by 9, and the answer of that is the answer of YOUR awesome question!

81÷9=????

C'mon, ya know it!
