use the values in the table to determine the slope.

Answer:

Step-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

Answer: [tex]2\frac{2}{9}[/tex]

Convert all Mixed Numbers into an Improper Fraction

Multiply 1×3 and get 3. Now add 3+1 and get 4.

1 1/3 = 4/3

Do Keep Change Flip (KCF)

Keep: 4/3

Change: ÷ into ×

Flip: 3/5 into 5/3

Multiply

[tex]\frac{4}{3}*\frac{5}{3}=\frac{20}{9}[/tex]

Divide

[tex]\frac{20}{9}=2\frac{2}{9}[/tex]

Q: How does 20/9 equal 2 2/9?

A: Divide 9 and 20 and get 2 r2 (r = remainder). The 2 becomes the mixed number. The remainder becomes the numerator. 9 becomes the denominator.

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

Answer:

Step-by-step explanation:

5 nights

The family have to stay 5 nights in order  to cost the same amount of money.

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.

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]

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°

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

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!

Answer:

m = 36

Step-by-step explanation:

Step 1:

3 ( 1/2m -3 ) = 45

Step 2:

3/2m - 9 = 45

Step 3:

3/2m = 54

Step 4:

54 ÷ 3/2

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

Step-by-step explanation:

You have to substitute n to get the answer therefore, substitution.

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 ]
