What is the value of the expression shown below?
(2/3)²+5×2-4

Answer:

A. -6

Step-by-step explanation:

Simplify the given expression.

(6x^4 - 3x^2) + (x^2 - 5)(qx^2 + 5) =

= 6x^4 - 3x^2 + qx^4 + 5x^2 - 5qx^2 - 25

= 6x^4 + qx^4 + 2x^2 - 5qx^2 - 25

= (6 + q)x^4 + (2 - 5q)x^2 - 25

Set ti equal to the given solution.

(6 + q)x^4 + (2 - 5q)x^2 - 25 = 32x^2 - 25

The solution has no 4th degree term, so

6 + q = 0

q = -6

As a check, the solution's x^2 term is 32x^2, so

(2 - 5q)x^2 = 32x^2

2 - 5q = 32

-5q = 30

q = -6

Once again, we get q = -6.

Answer: A. -6

Step-by-step explanation:

The graph that best represents an increasing function is (a) A graph shows a non linear curve that joins the ordered pairs (0, 0), and (2.5, 1), and (4, 3).

For a graph to represent an increasing function, then as the input values increases, the output values must also increase

This means that:

As the x values increases, the y values must also increase

Hence, the graph that best represents an increasing function is (a)

This is so because as x increases from 0 through 2.5 to 4, y increases from 0 through 1 to 3

Answer:

which type of equation just tell we are here to help if we can

Answer:  Take the information given in the situation. Consider the relationships between the amounts, numbers and unknowns that are in the description.

If the word "is" or "are" is included in the description, that is equivalent to an equal sign.

Words like "and," "also" "more than" and "combined" are clues that there may be addition. "Total" often means the sum of an addition equation.  

"From" and "difference" are clues that there is subtraction.

"Times" "by" and "of" art clues for multiplication. "Find the Area of. . ." dedinitely requires multiplication.

"Ratio," 'into' "per" and "among" are clues to division.

Use a letter x, y, d, t, or whatever helps identify the

Step-by-step explanation: Without a specific situation, it is impossible to give a specific answer.

Examples:  The total number of seats in the auditorium is 125. 75 tickets have been sold already. How many more tickets are left. (This is the unknown)

The Total is  the given 75 plus the unknown.

125 = 75 + x   is the equation to start with

What is three-fourths of twelve?  "What" is the unknown.

x = 3/4 × 12  is the  equation to start with.

The ratio of red marbles to blue marbles is 2:3  There are 25 marbles all together. How many red marbles and how many blue marbles.

In this question there are two equations

2r + 3b = 25 This is the equation for the total    r = 2b/3 is the division

Substitute the value of "r" from the second equation to solve the first equation

2(2b/3) + 3b = 25

Answer:

see below

Step-by-step explanation:

x - 2/5= 7

Add 2/5 to each side

x - 2/5 + 2/5 = 7+2/5

x = 7 2/5

or if

( x-2) /5 = 7

Multiply each side by 5

(x-2) /5 *5 = 7*5

x-2 = 35

Add 2 to each side

x-2+2 = 35+2

x = 37

Answer:

or

Step-by-step explanation:

x - 2/5= 7

find out what x is

x - 2/5 = 7

x - 2 = 7 (5)

x - 2 = 35

x = 35 + 2

x = 37

--------

or

x - 2/5 = 7

x = 7 + 2/5

Answer:

66

Step-by-step explanation:

Answer:

Lets numeralise the question,

According to question 32+ ? = 98

So if we take the unknown value as x then we will get,

32+x=98

So by transposing we get,

x=98-32

=  66

So 66 should be added to 32 to get 98

By the remainder theorem, dividing [tex]f(x)[/tex] by [tex]x-2[/tex] leaves a remainder of [tex]f(2)[/tex], which is

[tex]f(2)=2(2)^4+(2)^3-8(2)-1=\boxed{23}[/tex]

which makes B the correct answer.

The remainder when f(x) = 2x^4 + x^3- 8x - 1 is divided by x - 2 is 23

A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.

Polynomial based on degree is linear, quadratic, cubic.

The remainder theorem states that when a polynomial, f(x), is divided by a linear polynomial x - a, the remainder of is to f(a)

Given that f(x) = 2x⁴ + x³ - 8x - 1 is divided by x - 2

x - 2 = 0

x = 2

f(2) = 2(2)⁴ + (2)³ - 8(2) - 1 = 23

Hence The remainder when f(x) = 2x^4 + x^3- 8x - 1 is divided by x - 2 is 23

Answer: Orange.

Step-by-step explanation:

The graph of the slopes of the red function is equal to the derivate of the red function.

First, let's analyze the red function (from left to right).

First we can see that the red function is positive, and it decreases (so we must have a negative slope here).

Then we can see a little inflection point where the red function seems to be constant for a bit (here the slope must become zero for a little bit).

Then the red function keeps decreasing (so the slope is negative again).

Then the graph of the slope is:

Negative, then it increases to zero, and it decreases again.

The only graph that does this is the orange one, so the answer is orange.

Answer:

the answer is c

Step-by-step explanation:

Becuase he is given 100 dollars and he uses 20 dollars a day, so you put x with 20 to calculate how many days that he can spend $20 on

Day 1: money spent = 20

Day 2: total money spent = 20+20 = 2*20

So, for x days, total spent money should be 20*x = 20x

At an instant, say, after x days.

=> saving = total amount - spent

=> money left = 100 - 20x

=> y = 100 - 2x

=> y = - 2x + 100

[tex](f + g)(x) = - 4 {x}^{2} - 6x - 1 - {x}^{2} - 5x + 3 \\ [/tex]

[tex](f + g)(x) = - 5 {x}^{2} - 11x + 2 \\ [/tex]
