What is a characteristic of all cubic functions? (Pictures included)
Answer:
I believe it's A: They are always increasing.
Step-by-step explanation:
The cubic function is one where the coefficient a, b, c, and d are correlational the variable are real numbers and are polynomial numbers. The function is either one or three real roots. The graph of the function is a cubic curve.
The example of a cubic function is that of the forms of y = ax3 + bx2 + cx + d, where the a, b, c, and d are constants. The cube root function is inverse to the cube function.Hence they are increasing option A is correct.

-5m+10= -20+10
How do I check this problem
Answer:
m = 4
Step-by-step explanation:
-5m+10= -10
or, -5m = -10-10
or, m = -20/-5
or, m = 4

Solve for “x”
4x + 7 = 5
Answer:
x=-1/2 or -0.5
Step-by-step explanation:
You would subtract 7 on both sides and that leaves you with 4x=-2 then you would divided by 4 to get x=-0.5
Answer:
Here, this should work.
The answer is x = 1/2
What is the additive Inverse (zero pair) of 3k
Answer:
-3000
Step-by-step explanation:
an additive inverse of a number is a number, when added to, makes zero. So if its 3000 than the inverse would be -3000 since it equal 0

solve for b please help me
Answer:
B = 7 (?)
Step-by-step explanation:
(b + 3) / 5 = 2
5 (b + 3) / 5 = 2 x 5
Simplify it --> b + 3 = 10
b + 3 - 3 = 10 - 3 (subtract 3 from both sides)
B = 7

find the vertex parabola of f(x)= (x+1)² -3? please I need it right away
Answer:
(-1, -3)
Step-by-step explanation:
y = a(x – h)^2 + k, then the vertex is the point (h, k)
f(x) = (x+1)^2 - 3
so h = -1, and k = -3
so the vertex is (-1, -3)
Mike completed an online course that contained 20 core topics in a total of
40 learning hours. How many topics did he complete in 12 hours time?
Answer:
6 hours
Step-by-step explanation:
What you have to do is find the unit rate, which would be 20/40 which is .5 ( half an hour, 30 mins ) . Then you would do 30 x 12 = 360 ( 6 hours ).

Linn is making cookies. Each batch of cookies
requires 7/8 cup of flour for every 1/4 cup of sugar.
How can Linn find the number of cups of flour she needs to use with 4 cups of sugar?
Choose one option from each drop-down menu to answer the question.
To find the unit rate for the number of cups of flour for each cup of sugar, Linn can
Choose...
The unit rate is Choose...
Next Linn should
Choose...
to find that she needs Choose...
cups of flour.
Answer:
4 cups of sugar require 14 cups of sugar
Step-by-step explanation:
Given
[tex]\frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar[/tex]
Required
Determine the cups of flour for 4 cups of sugar
First, we need to determine the unit rate for 1 cup of sugar.
This is done by multiplying both sides by 4
[tex]4 * \frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar * 4[/tex]
[tex]\frac{7}{2}\ cup\ flour = 1\ cup\ sugar[/tex]
Next, we determine cup of flour for 4 cups of sugar.
This is done by multiplying both sides by 4
[tex]4 * \frac{7}{2}\ cup\ flour = 1\ cup\ sugar * 4[/tex]
[tex]2 * 7\ cup\ flour = 4\ cup\ sugar[/tex]
[tex]14\ cup\ flour = 4\ cup\ sugar[/tex]
Hence;4 cups of sugar require 14 cups of sugar
Solve G(x) for the given domain. Include all of your work in your final answer. Submit your solution.
G(x) = 3x 2 - 2x - 1
G(a + b) =
Answer: 3a^2+6ab+3b^2-2a-2b-1
Step-by-step explanation:
For G(x), we must plug in (a+b) into G(x):
G(a+b) = 3(a+b)^2-2(a+b)-1
= 3(a+b)(a+b)-2(a+b)-1
= factor: 3(a^2+ab+ab+b^2)- (2a+2b)-1
= multiply: 3a^2+3ab+3ab+3b^2-(2a+2b)-1
= now factor the last part: 3a^2+3ab+3ab+3b^2-2a-2b-1
= add/subtract: 3a^2+6ab+3b^2-2a-2b-1
Answer: 3a^2+6ab+3b^2-2a-2b-1
Answer:
Answer: 3a^2+6ab+3b^2-2a-2b-1
Step-by-step explanation:
For G(x), we must plug in (a+b) into G(x):
G(a+b) = 3(a+b)^2-2(a+b)-1
= 3(a+b)(a+b)-2(a+b)-1
= factor: 3(a^2+ab+ab+b^2)- (2a+2b)-1
= multiply: 3a^2+3ab+3ab+3b^2-(2a+2b)-1
= now factor the last part: 3a^2+3ab+3ab+3b^2-2a-2b-1
= add/subtract: 3a^2+6ab+3b^2-2a-2b-1
Answer: 3a^2+6ab+3b^2-2a-2b-1

We went to the market to buy some fruit. We decided to buy some apples, strawberries, and oranges. If we buy 2 apples, 3 boxes of strawberry, and 4 oranges, the fruit would cost $15.30. If we buy 1 box of strawberry, 4 apples, and 2 oranges, the fruit would cost $10.90. If we buy 1 orange, 5 apples and 2 boxes of strawberry, the fruit would cost $13.70. Use the Gaussian Elimination Method to solve for the price of each fruit.
Step-by-step explanation:
Let the amount of apples bought be x
Amount of strawberries bought be y and;
amount of oranges bought be z
If we buy 2 apples, 3 boxes of strawberry, and 4 oranges, the fruit would cost $15.30, then this will be expressed as;
2x+3y+4z = 15.30 ........... 1
If we buy 1 box of strawberry, 4 apples, and 2 oranges, the fruit would cost $10.90, this will be expressed as:
4x+y+2z = 10.90 ......... 2
If we buy 1 orange, 5 apples and 2 boxes of strawberry, the fruit would cost $13.70, this is expressed as:
5x+2y+x = 13.70 .......... 3
Solving the three equations simultaneously:
2x+3y+4z = 15.30 ........... 1
4x+y+2z = 10.90 ......... 2
5x+2y+z = 13.70 .......... 3
Reduce the number of equations
multiply equation 1 by 2 and subtract from equation 2
equation 1 * 2 will give:
4x+6y+8z = 30.6 ........... 4
eqn (4)-eqn(2)
6y-y + 8z-2z = 30.6-10.90
5y+6z = 19.7 ......... 5
Also multiply equation 2 by 5 and eqn 5 by 4 and subtract from each other.
eqn(2)* 5 will give:
20x+5y+10z = 54.5 .......... *
eqn(3) * 4 will give
20x+8y+4z = 54.8.......**
Subtsrct ** from *
8y-3y+(4z-10z)= 54.8-54.5
5y-6z = 0.3 .................. 6
Equate 5 and 6 and solve:
5y+6z = 19.7 ......... 5
5y-6z = 0.3 .................. 6
subtract:
6z+6z = 19.7+0.3
12z = 20
z = 20/12
z = 1.67
Substitute z = 1.67 into eqn 6
5y-6(1.67) = 0.3
5y - 10 = 0.3
5y = 10.3
y = 10.3/5
y = 2.06
Substitute z = 1.67 and y = 2.06 into equation 1
From 1:
2x+3y+4z = 15.30
2x+3(2.06)+4(1.67) = 15.30
2x+6.18+6.68 = 15.30
2x+12.86 = 15.30
2x = 15.30-12.86
2x = 2.44
x = 2.44/2
x = 1.22
Therefore 1 apple costs $1.22, 1 strawberry costs $2.06 and 1 orange costs $1.67

Find roots (zeroes) of : F(x) = 5x3+x2-32
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 5 and the Trailing Constant is -32.
The factor(s) are:
of the Leading Coefficient : 1,5
of the Trailing Constant : 1 ,2 ,4 ,8 ,16 ,32
Let us test ....

A Zoo keeps a tiger-to-lion ratio of 7:3. If the Zoo has room for 70 animals,
then how many of them can be tigers?
Answer:
49
Step-by-step explanation:
7x7=49
3x7=21
49+21=70
Answer:
49 tigers
Step-by-step explanation:
Let, there are 7x numbers of tigers
and 3x numbers of lions, where x is a proportionate constant.
Then by the condition,
7x+3x= 70
or, 10x =70
or, x = 7
so, tigers = 7×7= 49

Jillian is using integer tiles to add 7 + (negative 2). She uses the steps below. Step 1 7 positive tiles. Step 2 7 positive tiles and 2 negative tiles. Step 3 7 positive tiles and 2 negative tiles. 2 positive and 2 negative tiles are circled. Step 4 7 + (negative 2) = 2 Jillian has made an error. In which step does it occur? Step 1 Step 2 Step 3 Step 4 Mark this and return
Answer:
Step 4Step-by-step explanation:
Given the expression 7+(-2)
Let 7 be 7 positive tiles since it is a positive number
Let -2 be 2 negative tiles being a negative number
7+(-2) = 7 positive tiles and 2 negative tiles
note that + * - will give minus sigh (-), the expression will become:
7+(-2) = 7-2
7-2 = 5
Hence the expression gives 5 positive tiles not 2 positive tiles according to Jillian calculations in step 4.
Hence Jillian made an error in step 4

28 = 3x – 7x + 4
Check:
Answer:
x= -6
Step-by-step explanation:
28=3x - 7x + 4
Combine Like Terms:
28= -4x + 4
Subract four from both sides (in order to isolate the variable):
24= -4x
Divide by -4 from both sides:
x= -6
Answer:
x= -6
Step-by-step explanation:
1. Subtract the x's
28 = -4x + 4
2. Subtract the 4 by both sides
(28 - 4) = -4x + (4-4)
3. Solve
24 = -4x
4. Divide Both sides by -4
24/-4 = -4/-4 x
5. Solve
-6 = x or x = -6

question number 36 the answer is always true because rational numbers are numbers that can be turned into fractions or simple fractions easily and any integers that is positive added together will provide a positive answer.
37. the answer is always true because and a negative integer and a negative integer added together will give a negative answer.
38. sometimes true. a positive intergee plus a negative interger can give a positive or negative answer. eg -3+2=-1 but -4+8=4
39. always true. + multiply + =+
40. never true. - multiply - = +
