[tex]w(t) = - 2t + 1[/tex]
To find w(- 7) substitute the value of t that's - 7 into w(t) that's for every t in w(t) replace it with - 7
That's
[tex]w( - 7) = - 2( - 7) + 1 \\ = 14 + 1[/tex]

Your family is planning a vacation for spring break and want to get the best deal. Option
A costs $479 per night and includes airfare in the cost. Option B costs $129 per night
but will cost your family $1750 in airfare. How many nights will your family have to stay
in order for the vations to cost the same amount of money?
Answer:
Step-by-step explanation:
5 nights
The family have to stay 5 nights in order to cost the same amount of money.
Function in one variable:Let us consider that family is staying for x night.
Given that, Option A costs $479 per night and includes airfare in the cost.
So that, [tex]A(x)=479x[/tex]
Also Option B costs $129 per night but will cost your family $1750 in airfare.
So that, [tex]B(x)=129x+1750[/tex]
for the cost of same amount of money,
[tex]A(x)=B(x)\\\\479x=129x+1750\\\\479x-129x=1750\\\\350x=1750\\\\x=1750/350=5[/tex]
The family have to stay 5 nights in order to cost the same amount of money.

Hey can someone help me with this?
Answer:
m∠MON = 24°
Step-by-step explanation:
m∠LOM and m∠MON add up to 90°.
Step 1: Find x
2x + 46 + 3x - 6 = 90
5x + 40 = 90
5x = 50
x = 10
Step 2: Find m∠MON
m∠MON = 3x - 6
m∠MON = 3(10) - 6
m∠MON = 30 - 6
m∠MON = 24°

answer this for 18 points btw theres no fractions decimals just normal find th value of x
Answer:
x = 28°Step-by-step explanation:
From the question the figure above is a triangle.
The sum of angles in a triangle add up to 180°
To find the value of x add up all the angles and equate them to 180 to find the value of x
We have
50 + 2x + 3x - 10 = 180
5x + 40 = 180
5x = 180 - 40
5x = 140
Divide both sides by 5
We have the final answer as
x = 28°Hope this helps you
A population of beetles are growing according to a linear growth model. The initial population (week 0) is p0=6 and the population after 7 weeks is p7=83 find an explicit formula for the beetle population after n weeks.
Answer:
P(n)= p0 + 11(n)
Where p0= population of week 0
P(n) = population of n weeks
n= number of weeks
Step-by-step explanation:
Population of beetles in Week 0= 6
Population of beetles in Week 7= 83
From week 0 to week 7 there are 8 weeks.
But subtracting population of week 0 from population of week 7 gives
= 83-6
= 77
After the subtraction, we have 7 weeks remaining.
Dividing the remaining population by the number of weeks remaining
=77/7
= 11
For n number of weeks, population p of beetles
P(n)= p0 + 11(n)
Where p0= population of week 0
P(n) = population of n weeks
n= number of weeks
Express the following vector in the form v=v1i+v2j+v3k. 3u - v if u=(4,7,-3) and v=(2,-7,5).3u - v = ____ i + ____ j + _____ k.(Simplify your answers.)
Answer:
5i+14j-7kStep-by-step explanation:
Given the vectors u = (4,7,-3) and v=(2,-7,5), both vectors are 3-dimensional in nature and can also be rewritten as;
u = 4i+7j-3k and v = 2i-7j+5k
To get 3u-v, we will substitute the given vectors into the expression;
3u-v = 3(4i+7j-3k) - (2i-7j+5k)
open the parenthesis
3u-v = 12i+21j-9k - 2i + 7j - 5k
collect like terms
3u-v = (12i - 2i) + (21j + 7j) (-9k-5k)
3u - v = 10i+28j-14k
To simplify the answer, we will divide through by 2
3u - v = 10i/2+28j/2-14k/2
3u - v = 5i+14j-7k
Hence the simplified form of the expression is 5i+14j-7k
what is the solution to : 3(1/2 m - 3) =45
Answer:
[tex]m=36[/tex]
Step-by-step explanation:
We can solve for this equation by isolating [tex]m[/tex] on one side. To do this, we can "reverse" the equation.
[tex]3(\frac{1}{2}m - 3) = 45[/tex]
Let's divide both sides by 3.
[tex]3(\frac{1}{2}m-3)\div3 = 45\div3\\\\\frac{1}{2}m - 3 = 15[/tex]
Add 3 to both sides:
[tex]\frac{1}{2}m - 3 + 3 = 15 + 3\\\\\frac{1}{2}m = 18[/tex]
Multiply both sides by two (since [tex]\frac{1}{2}\cdot2=1[/tex])
[tex]\frac{1}{2}m \cdot 2 = 18 \cdot 2\\\\m = 36[/tex]
Hope this helped!

3. Lonnie has a gift card worth $600 for a local entertainment store. Movies cost $20 each and newly released video games cost $50 each. In order to use the gift card, Lonnte must purchase
at least thirteen items. Which is a combination of movies and newly released video games that Lonnie could purchase using his gift card? (2 points)
6 movies and 4 video games
14 movie and 7 video games
O O O O
2 movies and 10 video games
8 movies and 6 video games
Answer:
8 movies and 6 video games
Step-by-step explanation:
Given
[tex]Gift\ Card = \$600[/tex]
[tex]Movies =\ $20[/tex]
[tex]Video\ Game = \$50[/tex]
[tex]Minimum\ Items = 13[/tex]
Required
Determine the items Lonnie can afford
To solve this question, we make use of trial by error method by taking the options one at a time:
Option 1: 6 movies and 4 video games
This option can not be considered because the number of items is not up to the minimum Lonnte must purchase.
Option 2: 14 movies and 7 video games
[tex]Cost = 14 * \$20 + 7 * \$50[/tex]
[tex]Cost = \$280 + \$350[/tex]
[tex]Cost = \$630[/tex]
This option can not be considered because the cost of purchase is greater than Lonnte's worth of Gift card.
Option 3: 2 movies and 10 video games
This option can not be considered because the number of items is not up to the minimum Lonnte must purchase.
Option 4: 8 movies and 6 video games
[tex]Cost = 8 * \$20 + 6 * \$50[/tex]
[tex]Cost = \$160 + \$300[/tex]
[tex]Cost = \$460[/tex]
Hence, the correct option is 8 movies and 6 video games

What number comes next 57, 49, 41, 33, 25_
Answer:
18 I guess
Step-by-step explanation:
because we are subtracting all the number by 8
To find the common difference since all the values go done, we can subtract each value.
57 - 49 = 8
49 - 41 = 8
41 - 33 = 8
33 - 25 = 8
The common difference is 8 so to find the next number, all we need to do is subtract the last number by 8.
25 - 8 = 17
Therefore, the answer is 17

If f(x) = 3^x
+ 10 x and g(x) = 5x - 3, find ( f - g )(x).
Subtract the functions to get that answer
(f - g)(x) = f(x) - g(x)
(f - g)(x) = [ f(x) ] - [ g(x) ]
(f - g)(x) = [ 3^x + 10x ] - [ 5x - 3 ]
(f - g)(x) = 3^x + 10x - 5x + 3
(f - g)(x) = 3^x + 5x + 3
Answer:
3^x+5x+3
