Answer:
(-6,3)
Step-by-step explanation:
Find the slope of the line passing through the given points.
(2,3)(-1,-6)
Answer:
The slope is 3/1 or 3.
Step-by-step explanation:
The slope equation is y2-y1/x2-x1. Plug the coordinates into the equation and you get -6-3/-1-2 = -9/-3 = 9/3 = 3/1 = 3.
I need help ASAP thank you
According to the first scale, 2 red balls = 1 star.
According to the second scale, 2 triangles = 1 star
So,
1 triangle = 1 red ball
1 star = 2 red balls
1 red ball = 1 red ball
Therefore, 2 + 1 + 1 = 4 red balls
The last scale needs 4 red balls

Answer:
1) [tex]\frac{dy}{dx}=12x^2+6x-6[/tex]
2) [tex]x\leq-1\text{ or } x\geq 1/2[/tex]
Step-by-step explanation:
So we have the equation:
[tex]y=4x^3+3x^2-6x-1[/tex]
Part A)
We want to find the derivative of the above function. So:
[tex]\frac{dy}{dx}=\frac{d}{dx}[4x^3+3x^2-6x-1][/tex]
Expand:
[tex]\frac{dy}{dx}=\frac{d}{dx}[4x^3]+\frac{d}{dx}[3x^2]+\frac{d}{dx}[-6x]+\frac{d}{dx}[-1][/tex]
Use the power rule. Therefore, our derivative is:
[tex]\frac{dy}{dx}=3(4x^2)+2(3x)+(-6)+(0)[/tex]
Simplify:
[tex]\frac{dy}{dx}=12x^2+6x-6[/tex]
Part B)
We want to find the range of the values of x such that:
[tex]\frac{dy}{dx}\geq 0[/tex]
So, all we have to do is substitute our derivative in:
[tex]12x^2+6x-6\geq0[/tex]
And solve for this quadratic inequality!
Solve it normally. Pretend the inequality is with an equal sign. So:
[tex]12x^2+6x-6=0[/tex]
Divide everything by 6:
[tex]2x^2+x-1=0[/tex]
Factor. We can use -2 and 1. So:
[tex]2x^2+2x-x-1=0[/tex]
From the first two terms, factor out 2x.
From the third and fourth terms, factor out a negative. So:
[tex]2x(x+1)-(x+1)=0[/tex]
Grouping:
[tex](2x-1)(x+1)=0[/tex]
Zero Product Property:
[tex]2x-1=0\text{ or } x+1=0[/tex]
Solve for x in each case:
[tex]x=1/2\text{ or } x=-1[/tex]
So, the zeros of our function is -1 and 1/2.
Looking above, we can see that this is a greater than inequality.
Since this is a greater than inequality, our solution is all values to the left of the first zero and all values to the right of the second zero.
Therefore, our solution is:
[tex]x\leq-1\text{ or } x\geq 1/2[/tex]
In interval notation, this is:
[tex](-\infty,-1]\cup[1/2,\infty)[/tex]
So, for all values within the above interval, our derivative, dy/dx, will be greater than or equal to 0.
And we're done!

Kassy is traveling to Peru for her summer vacation. She looks at a map of the path of her flight. Her plane leaves from Texas, located at(5, 16) on the map’s coordinate grid, and then heads to its destination, Peru, located at(7, 8) on the map’s coordinate grid. Find the distance of Kassy's trip according to her map. Round your answer to the nearest hundredth.
Answer:
(6,12)
Step-by-step explanation:
Use the mid point formula to find the answer. Add the first x value to the second and divide by two for your x midpoint, then add the first y value to the second y value and divide by two for your y midpoint.
Kevin can travel 12 1/2 miles in 1/3 hours what is his average speed in miles per hours
Hey there! I'm happy to help!
We see that Kevin travels 12 1/2 miles in 1/3 hours. We want to see how far he travels in one hour. To do this, we simply multiply by 3!
12 1/2×3=37 1/2
Therefore, Kevin travels at 37 1/2 mph.
Have a wonderful day! :D

A triangle has side lengths of (6.2v-5.5)(6.2v−5.5) centimeters, (8.5v-6.7)(8.5v−6.7) centimeters, and (6.6w+7.6)(6.6w+7.6) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Given:
Side lengths of triangle are (6.2v-5.5) cm, (8.5v-6.7) cm, and (6.6w+7.6) cm.
To find:
The expression which represents the perimeter of the given triangle.
Solution:
We know that perimeter of a triangle is the sum of all sides of a triangle. So,
[tex]Perimeter=(6.2v-5.5)+(8.5v-6.7)+(6.6w+7.6)[/tex]
On combining like terms, we get
[tex]Perimeter=(6.2v+8.5v)+6.6w+(-5.5-6.7+7.6)[/tex]
[tex]Perimeter=14.7v+6.6w+(-4.6)[/tex]
[tex]Perimeter=14.7v+6.6w-4.6[/tex]
Therefore, the perimeter of the triangle is [tex]14.7v+6.6w-4.6[/tex].

2. You can use the formula a = ñ to find the batting average a of a batter who has
h hits in n times at bat. If a batter has a batting average of 265 and has been at bat
200 times, how many hits does the batter have?
Answer:
the batter have hits 754
Step-by-step explanation:
given:
If a batter has a batting average of 265 and has been at bat
200 times
find:
how many hits does the batter have?
batting average = 265 / 100 = 0.265
number of bat times = 200
let hits = h
aver = bat times
no. of hits
0.265 = 200 bat times
h
cross multiply:
0.265 h = 200
h = 200 / 0.265
h ≅ 754.72
therefore,
the batter have hits 754
Answer:
hits = 754
Step-by-step explanation:
If a batter has a batting average of 265 and has been at bat
200 times
batting average = 0.265
number of bat times = 200
aver = bat / h
0.265 = 200 / h
0.265 h = 200
h = 200 / 0.265
h ≅ 754.72
How do you find the product when two exponents have the same exponent and different bases?
Answer:
When you multiply two numbers or variables with the same base, you simply add the exponents. When you multiply expressions with the same exponent but different bases, you multiply the bases and use the same exponent.

Question 4 5 pts For the equation: -k - 4k = 3 (k – 10) - 6 (k - 6), what is the value of k?
K = -3
Step-by-step explanation:1. Simplify -k-4k to -5k
-5k=3(k-10)-6(k-6)
2. Distribute Parentheses/Expand
-5k=3k-30-6k+36
3.Simplify 3k-30-6k+36 to -3k +6
-5k=-3k+6
4. Add 3k to both sides
-5k+3k=6
5. Simplify -5k+3k to -2k
-2k=6
6. Divide both sides by -2
k=-6/2
7. Simplify 6/2 to 3
k=-3

Clara recorded the weather forecast in the table. Radio Forecast Day Forecast Monday 5° below 0 Tuesday 0° Wednesday 2° below 0 Thursday 3° above 0 On which day would she use a positive number to write the temperature? Monday Tuesday Wednesday Thursday
Answer: Thursday
Explanation: its Thursday because Monday is 5° below 0 is a negative number and Wednesday is 2° below 0 is also a negative number because its below 0. Now on Thursday its 3° above 0 which is the correct answer you need because its above the negative numbers of 0 which = a positive number now Tuesday is 0° which is just 0 nothing else.
Simple <3
Answer:
its Thursday

there are three consecutive integers with a sum of 39. which integers are they?
Answer:
The three integers are
11, 13, and 15.
Step-by-step explanation:
We shall consider the integers as
x, (x+2), and (x+4). The sum of these is 39, so we can write:
x+(x+2)+(x+4)=39
Open the brackets and simplify.
x+x+2+x+4=39 3x+6=39 Subtract 6 from each side.3x=33 Divide both sides by 3.x=11 Therefore: (x+2)=13and (x+4)=15
Answer:
The three integers are 11, 13, and 15 .
Step-by-step explanation:
We shall consider the integers as x, ( x + 2 ) , and ( x + 4 ) . The sum of these is 39, so we can write:
x + (x + 2) + (x + 4) = 39
Open the brackets and simplify.
x + x + 2 + x + 4 = 39
3x + 6 = 39
Subtract 6 from each side.
3x = 33
Divide both sides by 3.
x=11
Therefore: (x + 2) = 13 and (x + 4) = 15
Tell which set or sets the number below belongs to: natural numbers, whole numbers, integers, rational numbers, irrational numbers, or real numbers.
Answer:
irrational numbers and real numbers
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Tell which set or sets does the number 8/9 belong to: natural numbers, whole numbers, integers, rational numbers, irrational numbers, or real numbers?
Natural numbers are positive whole numbers and they start from 1. Negative numbers and zero are not natural numbers. Example of natural numbers are 1,2, 3, 4... and since 8/9 is a fraction, hence it is not a natural number.
8/9 is not also a whole number. Whole numbers are not written as fractions.
Integers are both positive and negative whole numbers including zero. They are not expressed as ratio of two whole numbers. They are not fractions as well hence 8/9 is not an integer.
Real numbers are both rational numbers and irrational numbers. They can be expressed as a ratio of two integers and can be expressed as decimal. Hence 8/9 is a real number and also irrational numbers.
An irrational number when written as decimal, the number after the decimal does not terminate.
8/9 = 0.888888888888...
As we can see, the number 8 after the decimal point is infinite, hence the reason why 8/9 is an irrational number
What is the product of 2x - 5 and 3x2 + 5x - 7? Write your answer in standard form.
Answer:
(2x - 5) (3x^2 + 5x - 7) = 6x^3 - 5x^2 - 39x + 35
Step-by-step explanation:
Given:
2x - 5 and 3x2 + 5x - 7
Product of two values means multiplication of the two values
(2x - 5) (3x^2 + 5x - 7)
6x^3 + 10x^2 - 14x - 15x^2 - 25x + 35
Collect like terms
6x^3 + 10x^2 - 15x^2 - 14x - 25x + 35
Simplify
6x^3 - 5x^2 - 39x + 35
(2x - 5) (3x^2 + 5x - 7) = 6x^3 - 5x^2 - 39x + 35
Therefore product of 2x - 5 and 3x2 + 5x - 7 is 6x^3 - 5x^2 - 39x + 35
