Answer:

-2x^3 + 1/7x - 1

Step-by-step explanation:

Answer:

-2x*3+x/7-1

Step-by-step explanation:

In standard form for polynomials, you would put the monomial with the highest degree in the front first, then the second most, and so on. -2x*3 has a cubic degree, so it will come first. x/7 has a constant degree, so it will come next. Finally, -1 has no degree, so it will come last.

mph = miles per hour. This person ran 13 miles PER HOUR, and there are 13 hours.

Answer:

3 sides - Triangle.

4 sides - Quadrilateral.

5 sides - Pentagon.

6 sides - Hexagon.

7 sides - Heptagon.

8 sides - Octagon.

9 sides - Nonagon.

10 sides - Decagon.

Step-by-step explanation:

Answer:

Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =riserun Slope = rise run .

as you should already know, to get the inverse of any relation we start off by doing a quick switcheroo on the variables and then solve for "y".

[tex]\stackrel{f(x)}{y}=\cfrac{3}{4}x+9\implies \stackrel{quick~switcheroo}{x=\cfrac{3}{4}y+9}\implies x-9=\cfrac{3y}{4}\implies 4x-36=3y \\\\\\ \cfrac{4x-36}{3}=y\implies \cfrac{4}{3}x-12=\stackrel{f^{-1}(x)}{y}\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

Answer:for .4 it is c=6

Step-by-step explanation:

first you do 6+3=9 then 3+5=8 then add 9+8=17

Answer:

We can use the ratio of proportional sides to help us solve the question.

m        4

---- = -----

3         2

Using cross products

2*m = 4*3

2m = 12

Divide each side by 2

2m/2 = 12/2

m = 6

The value of m that makes the triangles similar is 6

Answer:

20 TO 6, 20:6 OR 20/6

Step-by-step explanation:

All of the ratios that represent the number of students who prefer chocolate ice cream to the number of students who prefer vanilla ice cream, are 20 to 6, 20:6 or 20/6.

What is ratio?

A ratio displays the multiplicity of two numbers. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. Similarly, the ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.

Given:  There are 20 students in our class who prefer chocolate ice cream.

There are 6 students in our class who prefer vanilla ice cream.

Since the ratio can be expresses as, a/b, a:b or a to b.

So,

the ratio can be express as, 20 to 6, 20:6 or 20/6.

Therefore, all of the ratios that represent the number of students who prefer chocolate ice cream to the number of students who prefer vanilla ice cream, are 20 to 6, 20:6 or 20/6.

Answer:

a v-shaped graph with a minimum at (-2,-1) and x-intercepts at -1 and -3

Step-by-step explanation:

if you need to graph the function then start by creating an x-y table of values:

when x=0, y=1

so you the point: (0, 1)

when x=2, y=3

you have another point: (2,3)

when x=-2, y = -1

third point: (-2,-1)

when x=-3, y = 0

fourth point: (-3,0)

Answer:

y=-2x-7

Step-by-step explanation:

Answer:

Angle A = 180

Step-by-step explanation:

180=7x+40

Subtract 40 from both sides

140 = 7x

Divide 7 from both sides

20=x

Substitue 20 in for x

7(20)+40

140+40 = 180

Answer:

x = 18

< A = 166

Step-by-step explanation:

Angles A and B are corresponding angles, therefore they have the same measure. Using this information, you get the following equation:

7x + 40 = 3x + 112

-3x         - 3x

4x + 40 = 112

     - 40   - 40

4x = 72

Divide both sides by 4.

x = 18

Solve for A:

7(18) + 40 = 166
