Answer:
S = {-1, 1, 3, 5, 7}
Step-by-step explanation:
Given the set
{x | x is an odd integer between - 2 and 9}
Odd numbers between -2 and 9 are -1, 1, 3, 5, 7
Remember that -2 and 9 are excluded since the odd numbers must be in between the 2 values.
Hence the required set is S = {-1, 1, 3, 5, 7}
two times the sum of a number, x and 9 is at most four times the number. Write and solve an inequality to find to value of the number
Answer:
n ≥ 9
Step-by-step explanation:
let n = number
2(n + 9) ≤ 4n
2n + 18 ≤ 4n
18 ≤ 2n
9 ≤ n

Multiple the polynomial (4x^2 + 4x + 6)(7x + 5)
Answer:
28 x³ + 48 x² + 62 x + 30
Step-by-step explanation:
Explanation:-
Given that the polynomial equation
(4 x² + 4x +6)(7x+5)
Multiply
⇒ 4 x² ( 7 x+5) + 4 x ( 7x+5) + 6 (7x+5)
⇒ 28 x³ + 20 x² + 28 x² + 20 x + 42 x + 30

Answer:
[tex]x=-4\text{ and } x=3[/tex]
Step-by-step explanation:
We are given the second derivative:
[tex]g''(x)=(x-3)^2(x+4)(x-6)[/tex]
And we want to find its inflection points.
To do so, we will first determine possible inflection points. These occur whenever g''(x) = 0 or is undefined.
Next, we will test values for the intervals. Inflection points occur if and only if the sign changes before and after the point.
So first, finding the zeros, we see that:
[tex]0=(x-3)^2(x+4)(x-6)\Rightarrow x=-4, 3, 6[/tex]
So, we can draw the following number-line:
<----(-4)--------------(3)----(6)---->
Now, we will test values for the intervals x < -4, -4 < x < 3, 3 < x < 6, and x > 6.
Testing for x < -4, we can use -5. So:
[tex]g^\prime^\prime(-5)=(-5-3)^2(-5+4)(-5-6)=704>0[/tex]
Since we acquired a positive result, g(x) is concave up for x < -4.
For -4 < x < 3, we can use 0. So:
[tex]g^\prime^\prime(0)=(0-3)^2(0+4)(0-6)=-216<0[/tex]
Since we acquired a negative result, g(x) is concave down for -4 < x < 3.
And since the sign changed before and after the possible inflection point at x = -4, x = -4 is indeed an inflection point.
For 3 < x < 6, we can use 4. So:
[tex]g^\prime^\prime(4)=(4-3)^2(4+4)(4-6)=-16<0[/tex]
Since we acquired a negative result, g(x) is concave down for 3 < x < 6.
Since the sign didn't change before and after the possible inflection point at x = 3 (it stayed negative both times), x = -3 is not a inflection point.
And finally, for x > 6, we can use 7. So:
[tex]g^\prime^\prime(7)=(7-3)^2(7+4)(7-6)=176>0[/tex]
So, g(x) is concave up for x > 6.
And since we changed signs before and after the inflection point at x = 6, x = 6 is indeed an inflection point.

Which expression is equivalent to 6x+7-12*2-(3 to the power 2 +3)-x
Step-by-step explanation:
Questions about equivalent expressions usually feature both simple expressions and complex expressions. To check which complex expression is equivalent to the simple expression:
Distribute any coefficients: a(bx\pm c)=abx\pm aca(bx±c)=abx±aca, left parenthesis, b, x, plus minus, c, right parenthesis, equals, a, b, x, plus minus, a, c.
Combine any like terms on each side of the equation: xxx-terms with xxx-terms and constants with constants.
Arrange the terms in the same order, usually xxx-term before constants.
If all of the terms in the two expressions are identical, then the two expressions are equivalent.
Example
How do we solve for unknown coefficients?
Some questions will present us with an equation with algebraic expressions on both sides. On one side, there will be an unknown coeffient, and the question will ask us to find its value.
For the equation to be true for all values of the variable, the two expressions on each side of the equation must be equivalent. For example, if ax+b=cx+dax+b=cx+da, x, plus, b, equals, c, x, plus, d for all values of xxx, then:
aaa must equal ccc.
bbb must equal ddd.
To find the value of unknown coefficients:
Distribute any coefficients on each side of the equation.
Combine any like terms on each side of the equation.
Set the coefficients on each side of the equation equal to each other.
Solve for the unknown coefficient.
Example
How do we rearrange formulas?
Formulas are equations that contain 222 or more variables; they describe relationships and help us solve problems in geometry, physics, etc.
Since a formula contains multiple variables, sometimes we're interested in writing a specific variable in terms of the others. For example, the formula for the area, AAA, for a rectangle with length lll and width www is A=lwA=lwA, equals, l, w. It's easy to calculate AAA using the formula if we know lll and www. However, if we know AAA and www and want to calculate lll, the formula that best helps us with that is an equation in which lll is in terms of AAA and www, or l=\dfrac{A}{w}l=
w
A
l, equals, start fraction, A, divided by, w, end fraction.
Just as we can add, subtract, multiply, and divide constants, we can do so with variables. To isolate a specific variable, perform the same operations on both sides of the equation until the variable is isolated. The new equation is equivalent to the original equation.
The value of equivalent expression is,
⇒ 5x - 29
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 6x + 7 - 12 × 2 - (3² + 3) - x
Now, We can simplify as;
⇒ 6x + 7 - 12 × 2 - (3² + 3) - x
⇒ 6x + 7 - 24 - (9 + 3) - x
⇒ 6x + 7 - 24 - 12 - x
⇒ 5x - 29
Thus, The value of equivalent expression is,
⇒ 5x - 29

An orchard has 8 times many apple trees as pear trees. There are 981 trees in all. How many more apple trees than pear trees does have it?
Answer:
there are 763 more apple trees than pear trees
Step-by-step explanation:
so, first we write the words into equations.
8P = A because there are 8x apples per x pear, so to make it equal we must multiply pears by 8. P+A = 981. replacing "A" in the second equation with "8P" to get P+8P=981=9P divide both sides by 9 to get 109 pear trees. knowing this we can get 981-109=A=872 apple trees. the problem asks for A-P which we can replace the numbers to get (872)-(109)=763 more trees
There are 763 more Apple trees than Pear trees.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the number of pear trees be x.
An orchard has 8 times many apple trees as pear trees.
So, Apple trees = 8x
Now, total trees = 981
x+ 8x= 981
9x= 981
x= 981/9
x = 109
and, Apple trees = 8 (108)= 872.
So, there are 763 more Apple trees than Pear trees.
