2m-n / 3mn

Step-by-step explanation:

Answer: 5 miles

Step-by-step explanation:

Answer: D

Step-by-step explanation:

A and C are linear equations therefore we can eliminate them.

We are left betwen C and D.

C.

x²=25

x=5, x=-5

For C, we can eliminate because when you solve for x, you get 2 linear equations. You may see the x² and think it's linear, but when you solve it, you get 2 linear equations.

We are left with D. Even if you graph it and it doesn't look like a parabola or quadratic, it is still a quadratic equaiton. The 1/ makes it split both ways.

Answer:

(x (8 x^2 - 20 x + -33))/(2 (x - 3))

Step-by-step explanation:

Simplify the following:

4 x^2 + 2 x - (42 x)/(4 (x - 3))

The gcd of 42 and 4 is 2, so 42/4 = (2×21)/(2×2) = 2/2×21/2 = 21/2:

4 x^2 + 2 x - x/(x - 3) 21/2

Put each term in 4 x^2 + 2 x - (21 x)/(2 (x - 3)) over the common denominator 2 (x - 3): 4 x^2 + 2 x - (21 x)/(2 (x - 3)) = (8 (x - 3) x^2)/(2 (x - 3)) + (4 (x - 3) x)/(2 (x - 3)) - (21 x)/(2 (x - 3)):

(8 x^2 (x - 3))/(2 (x - 3)) + (4 x (x - 3))/(2 (x - 3)) - (21 x)/(2 (x - 3))

(8 (x - 3) x^2)/(2 (x - 3)) + (4 (x - 3) x)/(2 (x - 3)) - (21 x)/(2 (x - 3)) = (8 (x - 3) x^2 + 4 (x - 3) x - 21 x)/(2 (x - 3)):

(8 x^2 (x - 3) + 4 x (x - 3) - 21 x)/(2 (x - 3))

Factor x out of 8 (x - 3) x^2 + 4 (x - 3) x - 21 x, resulting in x (8 (x - 3) x^(2 - 1) + 4 (x - 3) - 21):

(x (8 x^(2 - 1) (x - 3) + 4 (x - 3) - 21))/(2 (x - 3))

2 - 1 = 1:

(x (8 x (x - 3) + 4 (x - 3) - 21))/(2 (x - 3))

8 x (x - 3) = 8 x^2 - 24 x:

(x (8 x^2 - 24 x + 4 (x - 3) - 21))/(2 (x - 3))

4 (x - 3) = 4 x - 12:

(x (4 x - 12 + 8 x^2 - 24 x - 21))/(2 (x - 3))

Grouping like terms, 8 x^2 + 4 x - 24 x - 21 - 12 = 8 x^2 + (-24 x + 4 x) + (-12 - 21):

(x (8 x^2 + (-24 x + 4 x) + (-12 - 21)))/(2 (x - 3))

4 x - 24 x = -20 x:

(x (8 x^2 + -20 x + (-12 - 21)))/(2 (x - 3))

-12 - 21 = -33:

Answer: (x (8 x^2 - 20 x + -33))/(2 (x - 3))

57 + (-6)=51

since 6 is negative you subtract 6 from 57

Answer:

10/3

Step-by-step explanation:

6 length is 2 height.

So 10(6+4) length is 10/3 height

Answer:

x = 10/3

Step-by-step explanation:

These two triangles are similar by AA similarity, as they share angle A, and both have right angles.

Not we can set up a ratio:

6/(6+4) = 2/x

6/10 = 2/x

3/5 = 2/x

Multiply both sides by 5x,

3x = 10

Divide both sides by 3:

x = 10/3

(a) Sample range appears to be a biased estimator since it consistently underestimated the population range.

Step-by-step explanation:

The sample ranges appear to be centered below 32

I got this right on Khan

In this exercise we have to use, in addition to the knowledge of statistics, the graph informed in the exercise in this way, we can say that:

Letter A

When we look at the graph, the maximum points are at 21 and 31, while the samples ranges appear to be centered below 32, that is we can say that the letter A is more appropietate.

Answer:

The height of trapezoid is 7km.

Step-by-step explanation:

Given that the area of trapezoid formula is A = 1/2×(a+b)×h where a and b represents the length and h is the height. By substituing the values, you are able to find the height :

[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]

Let a = 4km,

Let b = 8km,

Let area = 42km²,

[tex]42 = \frac{1}{2} \times (4 + 8) \times h[/tex]

[tex]42 = \frac{1}{2} \times 12 \times h[/tex]

[tex]42 = 6 \times h[/tex]

[tex]6h = 42[/tex]

[tex]h = 7 \: km[/tex]

Answer: 7km

How many days do you exercise in a week?

Step-by-step explanation:

The topic is students' weekly exercise so the question has to be about that. also, there are up to 7 days worth of data and there a 7 days in a week. so she most likely asked the question, "How many days do you exercise in a week?".

Answer:

B

Step-by-step explanation:

(12g²h⁷)(3g⁻²h⁻⁴) = 12 * 3 * g²⁺⁽⁻²⁾ * h⁷⁺⁽⁻⁴⁾

                            = 36 * g⁰ * h³

                            = 36 * 1 * h³

                            = 36h³

Any variable or constant to the power of zero is 1

a⁰ = 1 ;    12⁰ = 1  ;   (-5)⁰ = 1

The transformation for the given function is vertical compression or stretch.

The given functions are y=3x² and y=x².

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The graph for the given functions can be determined as follows

To find the transformation, compare the expression to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Horizontal Shift: None

Vertical Shift: None

Reflection about the x-axis: None

Reflection about the y-axis: None

Vertical Compression or Stretch: Compressed

Therefore, the transformation for the given function is vertical compression or stretch.
