F(x)=2x^2+6x-4
G(x)=5x^3-6x^2-3
Find (f+g)(x)
A function assigns the values. The value of (f+g)(x) is (5x³ - 4x² - 6x - 7).
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given F(x)=2x²+6x-4 and G(x)=5x³-6x²-3, therefore, the value of (f+g)(x) is,
(f+g)(x) = f(x) + g(x)
= 2x²+6x-4 + 5x³-6x²-3
= 5x³ - 6x² + 2x² - 6x - 4 - 3
= 5x³ - 4x² - 6x - 7
Hence, the value of (f+g)(x) is (5x³ - 4x² - 6x - 7).

Danielle is trying to solve the equation [tex]8^x=\frac{1}{64}[/tex]. Explain in detail how Danielle should solve this problem. Then solve it step by step showing all your work and tell Danielle what the answer should be.
Answer:
x=-2
Step-by-step explanation:
Given equation:
8^x= 1/64
Ensure both sides of the equation are in power format by changing 1/64
1/64 = 64^-1
8^x = 64^-1
2^3(x) = 2^6(-1)
The bases will cancel out each other
3(x) = 6(-1)
3x = -6
x = -6/3
x = -2
Check
8^x = 1/64
x = -2
8^-2
= 1/8²
= 1/8*8
= 1/64

To solve it, we can rewrite it as:
[tex]x^2 + 7x + 8 = 0[/tex]
Now if we use Bhaskara's formula, we get the solutions:
[tex]x = \frac{-7 \pm \sqrt{(7)^2 - 4*1*(8)} }{2} \\\\x = \frac{-7 \pm \sqrt{17} }{2}[/tex]
Then the two solutions are:

A rental car company charges $63.41 per day to rent a car and $0.05 for every mile driven. Ella wants to rent a car, knowing that: She plans to drive 275 miles. She has at most $200 to spend. What is the maximum number of days that Ella can rent the car while staying within her budget?
Answer:
2 days
Step-by-step explanation:
275 miles times 0.05 = $13.75 for mileage
200-13.75=186.25 left
186.25/63.41(daily fee)= 2.93

1. Write an inequality for this scenario in standard form.
2. Write the inequality in slope-intercept form.
3. Graph the inequality.
Inequalities help us to compare two unequal expressions. The inequality for this scenario in standard form is 2x + 3y > 30.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.

Answer:
x = 25
Step-by-step explanation:
First turn this into an equation:
[tex]\frac{4}{5}[/tex] times x = 20
Now divide both sides by [tex]\frac{4}{5}[/tex]. You can't divide by a fraction, instead you multiply by flipping the fraction. So now you're multiplying both sides by [tex]\frac{5}{4}[/tex].
20 times 5 = 100. Next you divide [tex]\frac{100}{4}[/tex]. This is equal to 25. You have completed the equation and now have the answer:
x = 25

(3+13-10)+14÷2+4 how do you solve this ?
Answer: 17
Step-by-step explanation:
Don't forget about PEMDAS. (parentheses, exponents, multiplication, division, addition, subtraction)
Start with parentheses
(3+13-10)... 13+3= 16, 16-10=6 ...
so (3+13-10)=6
Now we have...
6 + 14 / 2 + 4
No exponents so we go on.
no multiplication so we go on
Now division...
14 / 2 = 7 because 7 x 2 = 14
Now we have...
6 + 7 + 4
now we do addition, addition is commutative so you can add it in any order you want
6 + 7 = 13, 13 + 4 = 17
therefore, the answer is 17

Which scatter plot shows a negative linear association?
A.
B.
C.
D.
Answer:
D
Step-by-step explanation:
If you imagine the dots continued in a connected line, (imagining where the data points will likely go), the line's slope informs you if it is a negative (going down/negative slope) linear association or if it's a positive (going up/positive slope) linear association.
For A, it has a positive slope [as it increases].
For B, it also has a positive slope
For C, there is no correlation, the dots are not showing any trends
For D, there is a negative slope.
This means that the scatter plot D shows a negative linear association.
Option (D) shows a negative linear association between the variables is the correct answer.
A scatter plot is a type of data visualization that shows the relationship between different variables. Scatter plots are used to plot data points on a horizontal and a vertical axis in an attempt to show how much one variable is affected by another.
For the given situation,
The graph shows the data points on a horizontal and a vertical axis.
A scatter plot with an increasing value of one variable and a decreasing value for another variable can be said to have a negative correlation.
Among graphs, in option (D) when one variable tends to increase in the x-axis, the other variable decreases in the y-axis.
Hence we can conclude that option (D) shows a negative linear association between the variables is the correct answer.

The values of x, y, and z are 1, 2, and 3 respectively after using the substitution method.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have a linear equation in three variable:
2x + 3y - z = 5 ...(1)
4x - y - z = -1 ...(2)
x + 4y + z = 12 ...(3)
[tex]\rm \mathrm{Substitute\:}x=\dfrac{5-3y+z}{2}[/tex] (from the equation 1 and 2)
After solving:
[tex]\rm \begin{bmatrix}-7y+z+10=-1\\ \dfrac{5y+3z+5}{2}=12\end{bmatrix}[/tex]
From the above, two equations:
y =2
z =3
Plug the above values in equation 1
x = 1
Thus, the values of x, y, and z are 1, 2, and 3 respectively after using the substitution method.
