Answer:

x= 11

Step-by-step explanation:

(7x -1)° + (9x +5)°= 180° (adj. ∠s on a str. line)

7x -1 +9x +5= 180

16x +4= 180 (simplify)

16x= 180 -4 (-4 on both sides)

16x= 176 (simplify)

x= 176 ÷16

x= 11

The sum of the angles on a straight line is 180°

Answer:

3n^2+9+5n^4+55n

Step-by-step explanation:

Steps

$\left(3n^2+9+5n^4-3n\right)+\left(-9n\left(-7\right)-5n\right)$

$\mathrm{Remove\:parentheses}:\quad\left(a\right)=a,\:-\left(-a\right)=a$

$=3n^2+9+5n^4-3n+9n\cdot\:7-5n$

$\mathrm{Add\:similar\:elements:}\:-3n-5n=-8n$

$=3n^2+9+5n^4-8n+9\cdot\:7n$

$\mathrm{Multiply\:the\:numbers:}\:9\cdot\:7=63$

$=3n^2+9+5n^4-8n+63n$

$\mathrm{Add\:similar\:elements:}\:-8n+63n=55n$

$=3n^2+9+5n^4+55n$

An odd function is a function of a form [tex]y=x^n[/tex] where n is an odd number.

Some examples would be functions:

[tex]y=x,y=x^3,\dots[/tex].

A formal definition of odd function is the following.

(Algebraic proof).

Let [tex]f:\mathbb{R}\to\mathbb{R}[/tex] (real function).

The function is odd if the below equation is true for all x and -x for which the function is defined:

[tex]f(x)=-f(-x)[/tex].

Hope this helps.

Answer:

Step-by-step explanation:

real number can be irrational or integer.

otherwise there is no number which can be irrational,integer and real (all together)

Answer: The answer is B) there is no such number.

Step-by-step explanation:

So we have to find which number is irrational, and integer, and a real number. Let's examine the problem closely:

- irrational means not rational and cannot be represented by a simple fraction (like pi )

- an integer means a number that can be written without a fractional component ( -1, 2, 0, -10000 )

- and a real number means that it is not imaginary ( like 2i, [tex]\sqrt{-1}[/tex] )

And our choices here are:

-  -4/2

-  there is no such number

Let's take a look at -4/2. This number is a fraction, but it can be simplified down to -2/1, which is an integer. -2 is a real number, not an imaginary number. But, -2 is not irrational, because as it just was shown here, it CAN be represented by a fraction. So, since only two out of the three criteria are true, then we have to consider choice B.

Answer:

  an inverse variation function with a small value for k

Step-by-step explanation:

The attached graph shows the cases described. The function with the smallest function value for large x is ...

  an inverse variation function with a small value for k

___

On the graph, it is the green curve. The inverse variation functions both continue to decrease for large x, but the function with the smaller k value has a smaller function value.

Answer:an inverse variation function with a small value for k

Answer:

KE = 900,000t²

Step-by-step explanation:

The formula for calculating the kinetic energy of a body is expressed as KE = 1/2mv² where;

m is the mass of the sport car = 2000kg

v is the velocity of the car

Since v = at

v = 30t

Substituting the given values into the KE formula;

KE  1/2 * 2000 * (30t)²

KE = 1000*900t²

KE = 900,000t² Joules where t is the time measured in seconds

Answer:

KE = 900,000t²

Answer:

y = 4  (Answer C)

Step-by-step explanation:

We want to find side y.  The sine function relates the 30 degree angle, the hypotenuse 8 and the opposite side y:

                                          y

sin 30 degrees = 1/2 = -----------

                                           8

so y = 4  (Answer C)

Answer:

To test the effects of the multi-vitamin, we must test it on people with short-term memory loss. So the population should be people with short-term memory loss. The independent variable is the multi-vitamin and the dependent variable is the short term memory state of the people being tested. A control group can consist of people with short-term memory loss NOT being treated by the multi-vitamin.

Answer:

3:1

Step-by-step explanation:

hey there,

< We know Kaleel made 3x as many baskets as John.

We're going to make our ratio Kaleel:John.

The answer would be 3:1 because every time John makes 1 basket, Kaleel makes 3 baskets. If John made 2, then Kaleel would make 6, etc...

Answer:

a. Maurice walked farther.

b. 0.62 m

Step-by-step explanation:

Maurice

4.1 × 1.8 = 7.38 miles

Junnie

2.5 × 3.2 = 8 miles

This shows that Junnie walked more than Maurice.

8 - 7.38 = 0.62

Junnie walked 0.62 m more than Maurice

Answer:

  D.  Graph D

Step-by-step explanation:

The  "y <" tells you two things: (1) shading will be below the line, where y-values are less than those on the line, and (2) the line will be dashed, because the "equal to" case is not included.

Only one graph has a dashed line with shading below: Graph D.

Answer:

constant function has the same output no matter what are the inputs and it is written in the form : y=b where b is a constant  that does not change. the slope of this function always equal to zero.

slope intercept form : y=mx+b ( where m=0)

constant form : y=b ( y equal a constant that does not change)

Answer:

Undefined

Step-by-step explanation:

Use rise/run, (y2 - y1) / (x2 - x1)

Plug in the values:

(7 + 4) / ( 2 - 2)

11/0

= undefined, since you cannot divide by zero

The slope is undefined
