Answer:

  A)  Positive (4, 2, 0), negative (0)

Step-by-step explanation:

Descartes' rule of signs tells you the number of positive real roots is equal to the number of sign changes in the coefficients (with allowance for an even number of roots possibly being complex).

The signs of the coefficients are ...

  - + - + -

so there are 4 sign changes. The number of positive real roots will be 4, 2, or 0.

__

Changing the signs of odd-degree terms, you can use the same method to determine the number of negative real roots. With those signs changed, the signs of the coefficients are ...

  - - - - -

so there are 0 sign changes. The number of negative real roots is 0.

_____

The graph shows there are no real roots of either sign. All the roots are complex.

Evaluating and Solving Functions

LEARNING OUTCOMES

Evaluate and solve functions in algebraic form.

Evaluate functions given tabular or graphical data.

When we have a function in formula form, it is usually a simple matter to evaluate the function. For example, the function

[Math Processing Error]

f(x)=5−3x2

can be evaluated by squaring the input value, multiplying by 3, and then subtracting the product from 5.

HOW TO: EVALUATE A FUNCTION GIVEN ITS FORMULA.

Replace the input variable in the formula with the value provided.

Calculate the result.

Answer:

[tex]y=100x[/tex]

Step-by-step explanation:

Given that [tex]x[/tex] is the length measured in meters and

[tex]y[/tex] represents the same length measured in centimeters.

Let us first have a look at the relationship between meters and centimeters units of length.

1 unit of length in meters = 100 units of length in centimeters

Therefore, it can be said that:

2 units of length in meters = 200 units of length in centimeters

3 units of length in meters = 300 units of length in centimeters

4 units of length in meters = 400 units of length in centimeters

OR

[tex]x[/tex] units of length in meters = 100[tex]x[/tex] units of length in centimeters

It is given that [tex]y[/tex] is the length in centimeters.

Therefore, the proportional equation can be written as:

[tex]y=100x[/tex]

Answer:

angles BED and DEA, and angles AEC and BEC are supplementary angles

Step-by-step explanation:

If you do not know what supplementary angles are, then just know that it means two angles added together that equal 180 degrees. So, all you need to do is find two angles on the picture that equal 180 degrees when added together.

Answer:

Integers are a subset of Rational Numbers because all Integers are Rational Numbers.

Step-by-step explanation:

Hope this helped mark me as brainliest (:

Answer: Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers

Answer:

y = -0.5x -2

Step-by-step explanation:

if two lines are perpendicular, their product equals -1

_________________________________________

let the equation of required line be

y = mx + b as given in the problem to be slope intercept form

m = slope

given line

y = 2x

it is also in y = mx + b , comparing this with y =2x

m = 2 and b =0

now

as product of two perpendicular lines = -1

m*2 = -1

thus

m = -1/2 = -0.5

thus,

slope of required line is -0.5

in y = mx + b

m = -0.5

thus,

y = -0.5x + b

given that this line passes through(4,-4)

putting y = -4 and x = 4 in this equation we can find value of b

-4 = -0.5*4 + b

-4 = -2 + b

=> -4 + 2 = b

thus, b = -2

Thus, slope intercept form of equation is y = -0.5x -2

Answer:

C: 19

Step-by-step explanation:

To start we would resolve the absolute value of [tex]|-3|[/tex]. We know that absolute value is the distance from zero so it would be 3.

Our new equation is [tex]3+6/(4-1)*8[/tex]

Now we need to solve in the order of PEDMAS starting with parenthesis to get [tex]3+6/3*8[/tex]

Next in PEDMAS we have Division/Multiplication since we don't have any exponents. We do all the division and multiplication left to right so we would divide to get [tex]3+2*8[/tex]  and then multiply to get [tex]3+16[/tex].

Finally, we only have addition left over so our answer would be [tex]19[/tex]

Answers:

first term = 37

second term = 46

third term = 55

fourth term = 64

==========================================

Explanation:

Start at 37. Add 9 to this term to get the second term. Add 9 to that result to get the next term, and so on.

first term = 37

second term = 37+9 = 46

third term = 46+9 = 55

fourth term = 55+9 = 64

-----------

The nth term formula is

a(n) = 9n+28

It can be found by plugging a = 37 and d = 9 into the general form

a(n) = a + d*(n-1)

The  four terms of the arithmetic sequence with a first term of 37 and a common difference of 9 are: 37, 46, 55, and 64.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms remains constant.

Given:

First term (a1) = 37

Common difference (d) = 9

The arithmetic sequence can be represented as follows:

[tex]a_1[/tex]= 37

[tex]a_2[/tex] = [tex]a_1[/tex] + d

    = 37 + 9 = 46

[tex]a_3[/tex] = [tex]a_2[/tex] + d

   = 46 + 9 = 55

[tex]a_4[/tex] = [tex]a_3[/tex]+ d

   = 55 + 9 = 64

So, the first four terms of the arithmetic sequence are: 37, 46, 55, and 64.
