Kinsley's age is 7 years less than twice Jacobs age if kensley is 13 years old how old is Jacob
Answers
Answer:
Age of Jacob is 10 years.
Step-by-step explanation:
Let the age of Jacob = x years and age of Kinsley = y years
Then by first statement " Kinsley's age is 7 years less than twice of Jacob's age"
y = 2x - 7
By second statement " Kensley is 13 years old "
y = 3 years
By putting y = 13 years in the equation
13 = 2x - 7
2x = 13 + 7
2x = 20
x = [tex]\frac{20}{2}[/tex] = 10 years
Therefore, age of Jacob is 10 years.

Which equation shows an example of the associative property of addition?
(-7 + 1) + 71 = -7+ (i + 78)
(-7 + 1) + 7i = 71 +(-7i+1)
71% (-77 + 1) = (71-71) + (7ix)
(-71 + 1) + 0 = (-71 +1)
Answers
D
(-71+1) + 0 = (-71+1)
This is because the whole equation involves addition thus it is an example of associative property of addition
Answer:
(-71 + 1) + 0 = (-71 +1)
Step-by-step explanation:
Given 3 numbers: a,b,c
Associative property of addition: (a + b) + c = a + (b + c)
On this case: a= -71
b = 1
c = 0
(a + b) + c = (-71 + 1) + 0 = -70 + 0 = -70
(-71 + (1 + 0)) = (-71 + 1) = -70
Both the sums are equal to -70 and hence the associative property of addition for the three numbers a= -71, b = 1, c= 0 holds.
All the other options in the question contain a reference to variable i and does not have the same three values a,b,c on both sides of the equality. So they do not represent the associative property.
What are the solutions to the equation 4x2+3x=24-x
Answers
Answer:
x=2 x=-3
Step-by-step explanation:
4x2+3x=24-x
Subtract 24 from each side
4x^2 +3x -24 = 24-24 -x
4x^2 +3x -24 = -x
Add x to each side
4x^2 +3x+x -24 = -x+x
4x^2 +4x -24 = 0

Using the zero product property
x-2 =0 x+3 =0
x-2+2=0+2 x+3-3=0-3
x=2 x=-3
Answer:x=-3 , x = 2
Step-by-step explanation:
First move the expression ( 24-x) to the left.
This gives us 4x^2+3x+24-x.
Collect the like terms which gives us 4x^2+4x+24
4x^2+4x-24 = 0. Divide both sides by 4.
x^2 + x-6 = 0
Factorise the expression so you get (x+3)(x-2)=0
Solve the equations x+3 = 0 and x-2=0
The final solutions are x=-3 and x=2.

The inequality x - 7 > -20 is solved by adding 7 to both sides, resulting in x > -13. The graph of this inequality has an open circle at -13 with shading to the right.
To solve the inequality x - 7 > -20, you want to isolate the variable x on one side. You can do this by adding 7 to both sides of the inequality:
x - 7 + 7 > -20 + 7
x > -13
So, the solution to the inequality is x > -13. To graph this solution on a number line, you would draw an open circle at -13 and shade to the right, indicating that x can be any value greater than -13 but not including -13 itself.

5)
a. it dips between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)
b. it is taken at the vertex aka the lowest point so the height is -0.25
Answer:
Part 1:
[tex]y= (x-4)(x-5)[/tex]
Part 2:
[tex](\frac{9}{2}, - \frac{1}{4})[/tex]
Part 3:
[tex]Y=20[/tex]
Part 5:
The height:
[tex]-\frac{1}{4}[/tex]
The time:
[tex]\frac{9}{2}[/tex]s
Step-by-step explanation:
[tex]y = x^{2} -9x+20[/tex] Is a quadratic equation.
Part 1:
We use [tex]x = \frac {-b \pm \sqrt {b^2 - 4ac}}{2a}[/tex] to factor quadratic equations
[tex]y = x^{2} -9x+20[/tex]
a=1 b=-9 c=20
[tex]x = \frac {-(-9) \pm \sqrt {(-9)^2 - 4(1)(20)}}{2(1)}[/tex]
[tex]x = \frac {9 \pm \sqrt {81 -80}}{2}[/tex]
[tex]x = \frac {9 \pm {1}}{2}[/tex]
we solve both possibilities
[tex]x = \frac {9 + {1}}{2}=5[/tex]
[tex]x = 5[/tex]
[tex]x = \frac {9 -{1}}{2}=4[/tex]
[tex]x=4[/tex]
The factored form would be
[tex]y= (x-4)(x-5)[/tex]
Part 2:
We use the formula to find the x coordinate of the vertex of a parabola
[tex]V_{x}=\frac{-b}{2a}[/tex]
[tex]y = x^{2} -9x+20[/tex]
a=1 b=-9 c=20
[tex]V_{x}=\frac{9}{2}[/tex]
Now we substitute the value of x in [tex]y = x^{2} -9x+20[/tex] to find the value of the coordinate y of the vertex
[tex]y = \ (\frac{9}{2} )^{2} -9(\frac{9}{2}) +20\\ y= \frac{81}{4} -\frac{81}{2} +20\\ y= -\frac{1}{4}[/tex]
The vertex of the parabola is
Vertex:
[tex](\frac{9}{2}, - \frac{1}{4})[/tex]
Part 3:
the y-intercept is when the value of x = 0.
We substitute this value in [tex]y = x^{2} -9x+20[/tex]
[tex]y = 0^{2} -9(0)+20= 20[/tex]
The y-intercept is [tex]y=20[/tex]

(06.02 mc) the equation of line cd is y=3x-3. Write an equation of a line perpendicular to line cd in slope intercept form that contains points 3,1
Answers
Answer:
y = - [tex]\frac{1}{3}[/tex] x + 2
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 )
y = 3x - 3 ← is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex], hence
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation of the perpendicular line
To find c substitute (3, 1) into the partial equation
1 = - 1 + c ⇒ c = 1 + 1 = 2
y = - [tex]\frac{1}{3}[/tex] x + 2 ← equation of perpendicular line

Add 7 to boht sides of the equation:
[tex]-7+9x+7=20+7\\\\9x=27[/tex]
And finally, divide both sides by 9:
[tex]\frac{9x}{9}=\frac{27}{9}\\\\x=3[/tex]
How many ounces of trial mix are in a bag that weighs.908 kilograms?
Answers
Answer:
32028.8 ounces
Step-by-step explanation:
We are given that there are 908 kilograms of of trial mix are in a bag and we are to find the number of ounces of the same amout of mix in the bag.
For that, we will use the ratio method.
We know that, 1 kg = 35.274, so:
[tex] \frac { 1 k g }{908kg} =\frac{35.274 oz}{x}[/tex]
[tex]x=32028.8[/tex]
Therefore, there are 32028.8 ounces of mix in the bag.
Final answer:
To find the amount of trail mix in ounces from 0.908 kilograms, convert the weight to grams and then to ounces using the conversion of 1 oz = 28.35 g, resulting in approximately 32.012 ounces of trail mix.
Explanation:
To convert the weight of the trail mix from kilograms to ounces, we need to use the conversion factor: 1 oz is produced by a mass of 28.35 g. First, convert the kilograms to grams by multiplying by 1000, because there are 1000 grams in a kilogram. Then, once we have the weight in grams, we can convert grams to ounces using the provided conversion rate.
Here's the calculation step by step:
Convert kilograms to grams: 0.908 kg × 1000 = 908 grams.
Convert grams to ounces: 908 g ÷ 28.35 g/oz = 32.012 ounces (rounded to three decimal places).
Thus, a bag that weighs 0.908 kilograms contains approximately 32.012 ounces of trail mix.

This is one way of doing it. Break down every number and every variable into a product of the simplest factors. Then see how many of each factor appear in both monomials.
12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h
g^5h^2 = g * g * g * g * g * h * h
So far you see every single prime factor of each monomial.
Now I will mark the ones that are present in both. Those are the common factors.
12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h
g^5h^2 = g * g * g * g * g * h * h
The greatest common factor is the product of all the factors that appear in both monomials.
GCF = g * g * g * g * g * h * h = g^5h^2

=6x^3-3x^3y^2
the answer is 3x^3(2-y^2).
6x^3 + (-3x^3y^2) =
6x^3 - 3x^3y^2 =
3x^3(2-y^2)

Answer:
[tex] y = 2 5 0 ( 0 . 8 9 ) ^ x [/tex]
Initial value: 250
Decay
Decay rate: 11%
[tex] y = 4 0 ( 1.11 ) ^ x [/tex]
Initial value: 40
Growth
Growth rate: 11%
Step-by-step explanation:
The function we have on the left of the table is:
[tex] y = 2 5 0 ( 0 . 8 9 ) ^ x [/tex]
Initial value (when x = 0): [tex] y = 2 5 0 ( 0 . 8 9 ) ^ 0 [/tex]
y = 250 (initial value)
Growth or Decay: 0.89 < 1 so decay
Decay rate: (1 - 0.89) * 100 = 11%
Function on right side:
[tex] y = 4 0 ( 1.11 ) ^ x [/tex]
Initial value (when x = 0): [tex] y = 4 0 ( 1 . 1 1 ) ^ 0 [/tex]
y = 40 (initial value)
Growth or decay: 1.11 > 1 so growth
Growth rate: (1.11 - 1) * 100 = 11%

3+5/2 = 4
The median is 4
Hope this helps!
Answer:
4
Step-by-step explanation:
The median is the middle, since the amount of data is an even number we need to add up the third number and fourth number. These are 3 and 5 respectively. Adding these up gives up 8. Dividing this by 2 is 4.
