Henry has 13 chances to get a second turn.
Step-by-step explanation:
When two number cubes numbered from 1 to 6 are rolled, the number of possible outcomes are 36.
The 36 possible outcomes are as follows :
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)
(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)
(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)
(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)
(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)
(6,1), (6,2), (6,3), (6,4), (6,5), (6,6).
It is given that, Henry gets the second turn if he rolls a sum that is an even number less than 10.
Therefore, the even numbers less than 10 are {2,4,6,8}.
Check for the sum of outcomes that gives the result of even number less than 10.
Sum of (1,1) (1,3) (1,5) gives 2,4,6 which are even numbers less than 10 ⇒ 3 chances.Sum of (2,2) (2,4) (2,6) gives 4,6,8 which are even numbers less than 10 ⇒ 3 chances.Sum of (3,3) (3,5) gives 6 and 8 which are even numbers less than 10 ⇒ 2 chances.Sum of (4,2) (4,4) gives 6 and 8 which are even numbers less than 10 ⇒ 2 chances.Sum of (5,1) (5,3) gives 6 and 8 which are even numbers less than 10 ⇒ 2 chances.Sum of (6,2) gives 8 which is a even number less than 10 ⇒ 1 chance.The total number of chances to get second turn = 3+3+2+2+2+1 = 13 chances.
Therefore, Henry has 13 chances to get a second turn.
1. What are the solutions (coordinate points) to the system of equations?
y=x^2+5x+6 and y=3x+6
2. Prove algebraically what type of function this is (even, odd, or neither).
f(x)=x^6-x^4
3. Given the function f(x)=x^2+3x-2
What is the average rate of change for the function from 2 to 6? Show your work.
Question 1
The given system of equations is:
[tex]y = {x}^{2} + 5x + 6 \\ y = 3x + 6[/tex]
Equate the two equations:
[tex] {x}^{2} + 5x + 6 = 3x + 6[/tex]
Rewrite in standard form:
[tex] {x}^{2} + 5x - 3x + 6 - 6 = 0[/tex]
[tex] {x}^{2} + 2x = 0[/tex]
[tex]x(x + 2) = 0[/tex]
[tex]x = 0 \: or \: x = - 2[/tex]
When we put x=0, in y=3x +6, we get:
[tex]y = 3(0) + 6 = 6[/tex]
One solution is (0,6)
When we put x=-2, into y=3x+6, we get:
[tex]y = 3( - 2) + 6 = 0[/tex]
Another solution is (-2,0)
The solutions are; (0,6) and (-2,0)
Question 2:
The function is
[tex]f(x) = {x}^{6} - {x}^{4} [/tex]
Let us put x=-x,
[tex]f( - x) = {( - x)}^{6} - {( - x)}^{4} [/tex]
This gives:
[tex]f( - x) = {x}^{6} - {x}^{4} [/tex]
We can observe that:
[tex]f(x) = f( - x)[/tex]
This is the property of an even function.
Question 3:
The given function is
[tex]f(x) = {x}^{2} + 3x - 2[/tex]
The average rate of change of f(x) from x=a to x=b is given as:
[tex] \frac{f(b) - f(a)}{b - a} [/tex]
This is the slope of the secant line connecting the two points on f(x)
From x=2 to x=6, the average rate of change
[tex] = \frac{f(6) - f(2)}{6 - 2} \\ = \frac{ {6}^{2} + 3 \times 6 - 2 - {2}^{2} - 3 \times 2 + 2 }{4} \\ = \frac{36 + 18 - 4 - 6}{4} \\ = \frac{44}{4} \\ = 11[/tex]
The average rate of change is 11

Write the equation of a line in slope-intercept form whose slope is 6 and y-intercept is -7
Answer:
y = 6x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 6 and c = - 7, thus
y = 6x - 7 ← equation of line
Final answer:
The equation of the line with a slope of 6 and y-intercept of -7 is y = 6x - 7.
Explanation:
The equation of a line in slope-intercept form is y = mx + b, where m represents the slope and b is the y-intercept. In this case, we are given a slope (m) of 6 and a y-intercept (b) of -7. Thus, by substituting these values into the slope-intercept formula, we get the equation of the line as y = 6x - 7.

Step-by-step explanation:
two friends bought a $14 pizza. Each person bought their own drink. The total cost of the food can be represented by the expression $2x + $14. What expression represents the cost of food for one person
The expression representing the cost of food for one person is $x + $7.
For the expression that represents the cost of food for one person if two friends bought a $14 pizza, and each person bought their own drink at $2x (where x is the number of drinks).
To find the cost for one person, we start with the total cost expression $2x + $14. Since there are two friends, we divide this total cost by 2. The expression for the cost of food for one person is $x + $7. This represents the individual cost of one person's drink at $2x, divided by 2, plus half of the pizza cost, which is $14 divided by 2, resulting in $7.

What is subtracting fractions from mixed numbers for grade 4
Answer:
see below
Step-by-step explanation:
So when you have mixed numbers, you have to turn them into regular fractions. How you change them into regular fractions is multiplying the whole number by the denominator (the bottom number in the fraction) and then adding that number to the numerator (the top number in the fraction). So, for example you have
3[tex]\frac{2}{3}[/tex]
3 x 3 = 9
9 + 2 = 11
so, 3[tex]\frac{2}{3}[/tex] = [tex]\frac{11}{3}[/tex]
After you change the mixed fractions that you have into normal fractions, then you can normally subtract the two fractions. If they have the same denominator, then you just subtract the numerators like normal numbers and leave the denominators alone.
[tex]\frac{11}{3}[/tex] - [tex]\frac{2}{3}[/tex] = [tex]\frac{9}{3}[/tex]
If there are different denominators, then you have to multiply one or more fractions by any number so that both fractions have the same denominator.
For example,
[tex]\frac{11}{3}[/tex] - [tex]\frac{7}{6}[/tex]
you have to multiply [tex]\frac{11}{3}[/tex] by two, so that the denominator will equal six. This is the only way that you will be able to add or subtract the two fractions.
2([tex]\frac{11}{3}[/tex]) = [tex]\frac{22}{6}[/tex]
[tex]\frac{22}{6}[/tex] - [tex]\frac{7}{6}[/tex] = [tex]\frac{22-7}{6}[/tex] = [tex]\frac{15}{6}[/tex]
Then, if you are asked to, this fraction can be simplified if you divide both the denominator and the numerator by [tex]\frac{3}{3}[/tex], so
[tex]\frac{15}{6}[/tex] divided by [tex]\frac{3}{3}[/tex] is equal to [tex]\frac{5}{2}[/tex].
This works because [tex]\frac{3}{3}[/tex] = 1.

First of all, we have product of 2 functions [tex]e^{1/x}[/tex] and [tex]x^{2}[/tex]
[tex]y^{'} =u\frac{dv}{dx}+v\frac{du}{dx}[/tex]
Let [tex]u=e^{1/x}[/tex] and [tex]v=x^{2}[/tex]
using chain rule for [tex]u[/tex], [tex]\frac{du}{dx}=-\frac{1}{x^2}[/tex]
and [tex]\frac{dv}{dx}=2x[/tex]
Therefore,
[tex]y^{'} =u\frac{dv}{dx}+v\frac{du}{dx}=e^{1/x}(2x)+x^{2} (-\frac{1}{x^2})=e^{1/x}(2x-1)[/tex]

Marvin Martian, Aly Alien, and Hank Human are all looking for a hidden spaceship. Their probabilities of
finding the spaceship first are as follows:
P(Marvin wins) = 30%
P(Aly wins) = 0.2
P(Hank wins)
Put the following events in order from least to most likely.
Aly wins
Hank wins
Marvin wins
Answer: Aly , Marvin, Hank
Step-by-step explanation:
Aly has the lowest with 20, Marvin has 30, and hank has 50. it says least to mostly likely to win
The question pertains to probabilities. It has been determined that the most probable event is either Hank winning or Marvin winning, and it's least likely for Aly to win.
Explanation:The question is regarding the probability of three individuals, Marvin Martian, Aly Alien, and Hank Human, finding a hidden spaceship first. We know the probabilities of Marvin and Aly finding it first but the probability of Hank finding it is not given.
However, from the properties of probability, we know that the sum of the probabilities for all possible outcomes is 1. Therefore, if we add the probabilities of Marvin and Aly finding the spaceship first, we get 0.30(30%) + 0.2(20%) = 0.5(50%). We then subtract this from 1 to get Hank's probability, which is, therefore, 1 - 0.5 = 0.5(50%).
So, in order from least to most likely: Aly wins (0.2 or 20%), then Hank and Marvin are equally likely to win (0.5 or 50% each).

30% of number A is 10 more than 20% of number B. 30% of number B is 35 more than 20% of number A. Find the numbers A and B.
PLEASE PLEASE DUE TODAY!!!
Final answer:
To solve for A and B, we translated the word problem into two algebraic equations and then solved the system of equations step-by-step to find that A equals 200 and B equals 250.
Explanation:
We are given two equations based on the relationship between 30% of number A and 20% of number B, and vice versa. Let's translate the words into algebraic expressions where A and B represent the numbers we need to find:
0.30A = 0.20B + 10 (Equation 1)
0.30B = 0.20A + 35 (Equation 2)
Now let's solve this system of equations step-by-step:
Multiply both sides of Equation 1 by 10 to clear out decimals: 3A = 2B + 100.
Multiply both sides of Equation 2 by 10 as well: 3B = 2A + 350.
Rearrange Equation 1 to get A on its own: A = (2B + 100) / 3.
Substitute the expression for A from step 3 into Equation 2: 3B = 2((2B + 100) / 3) + 350.
Multiply through by 3 to clear the fraction: 9B = 4B + 200 + 1050.
Simplify to find B: 5B = 1250, so B = 250.
Substitute B back into the equation from step 3 to find A: A = (2(250) + 100) / 3, so A = 200.
Therefore, the numbers we are looking for are A = 200 and B = 250.

If (6,39) and (-5,-49) are two anchor pint find the equation of the line
Answer:
[tex]y =8x+9[/tex]
Step-by-step explanation:
The points are (6,39) and (-5,-49)
We need to find the equation of this line.
The slope is given by:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
[tex]m = \frac{ - 49 - 39}{ - 5 - 6} [/tex]
[tex]m = \frac{ - 88}{ - 11} [/tex]
[tex]m = 8[/tex]
We use the formula:
[tex]y-y_1=m(x-x_1)[/tex]
We substitute the point (6,39) and m=8 to get:
[tex]y - 39 = 8(x - 6)[/tex]
We expand to obtain:
[tex]y - 39=8x-48[/tex]
[tex]y =8x-48 + 39[/tex]
[tex]y =8x + 9[/tex]
To find the equation of the line passing through two points, we can use the point-slope form of a linear equation:
[tex]\[y - y_1 = m(x - x_1)\][/tex]
Where:
- [tex]\( (x_1, y_1) \)[/tex] is one point on the line.
- [tex]\( m \)[/tex] is the slope of the line.
First, let's find the slope (\(m\)) using the two given points:
[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]
Given points:
[tex]\( (x_1, y_1) = (6, 39) \)\( (x_2, y_2) = (-5, -49) \)\[ m = \frac{-49 - 39}{-5 - 6} \]\[ m = \frac{-88}{-11} \]\[ m = 8 \][/tex]
Now, we have the slope (\(m\)). We can choose either of the two given points and plug them into the point-slope form. Let's use \( (6, 39) \):
[tex]\[ y - 39 = 8(x - 6) \][/tex]
Now, we can simplify this equation to get it into slope-intercept form (\(y = mx + b\)):
[tex]\[ y - 39 = 8x - 48 \]\[ y = 8x - 48 + 39 \]\[ y = 8x - 9 \][/tex]
So, the equation of the line passing through the points (6, 39) and (-5, -49) is [tex]\( y = 8x - 9 \).[/tex]

What is the horizontal asymptote of the rational function f(x) = 3x / (2x - 1)?
Answer:
Step-by-step explain
Find the horizontal asymptote for f(x)=(3x^2-1)/(2x-1) :
A rational function will have a horizontal asymptote of y=0 if the degree of the numerator is less than the degree of the denominator. It will have a horizontal asymptote of y=a_n/b_n if the degree of the numerator is the same as the degree of the denominator (where a_n,b_n are the leading coefficients of the numerator and denominator respectively when both are in standard form.)
If a rational function has a numerator of greater degree than the denominator, there will be no horizontal asymptote. However, if the degrees are 1 apart, there will be an oblique (slant) asymptote.
For the given function, there is no horizontal asymptote.
We can find the slant asymptote by using long division:
(3x^2-1)/(2x-1)=(2x-1)(3/2x+3/4-(1/4)/(2x-1))
The slant asymptote is y=3/2x+3/4
Answer:
y = 3/2.
Step-by-step explanation:
This is the ratio of the coefficients of the terms in x of highest degree of the function:
y = 3/2.

x > -4
Step-by-step explanation:
Step 1: To combine like terms means to add the same variable numbers together.
-6x + 5 - 4x < 45
-10x + 5 < 45
Step 2: Subtract 5 from both sides
-10x + 5 - 5 < 45 - 5
-10x < 40
Step 3: Divide both sides by -10
-10x / -10 < 40 / -10
Since you divided by a negative, you need to reverse/flip the sign.
x > -4
Answer: x > -4
Steps to solve:
-6x + 5 – 4x < 45
~Combine Like Terms
(-6x - 4x) + 5 < 45
~Simplify
-10x + 5 < 45
~Subtract 5 to both sides
-10x + 5 - 5 < 45 - 5
~Simplify
-10x < 40
~Divide -10 to both sides and switch the symbol since we're dividing a negative number
-10x/-10 > 40 / -10
~Simplify
x > -4

[tex]\frac{-25}{-5}=5,\:\quad \frac{-125}{-25}=5,\:\quad \frac{-625}{-125}=5[/tex]
[tex]\mathrm{The\:ratio\:of\:all\:the\:adjacent\:terms\:is\:the\:same\:and\:equal\:to}[/tex]
[tex]r=5[/tex]
So, the sequence is geometric.
as
[tex]\mathrm{The\:first\:element\:of\:the\:sequence\:is}[/tex]
[tex]g_1=-5[/tex]
[tex]r=5[/tex]
so
[tex]g_n=g_1\cdot r^{n-1}[/tex]
[tex]\mathrm{Therefore,\:the\:}n\mathrm{th\:term\:is\:computed\:by}\:[/tex]
[tex]g_n=-5\cdot \:5^{n-1}[/tex]
Therefore, Li Jing's formula i.e. [tex]\boxed{g_n=-5\cdot \:5^{n-1}}[/tex] is right.
