Need help asap giving 20 points for right answer!!

Step-by-step explanation:

f(x) = 5x - 20

f(-1) = 5(-1) - 20 = - 5 - 20

= - 25

g(x) = x² + 5x - 11

g(2) = 2² + 5(2) - 11 = 4 + 10 - 11

= 3

Thus, f(-1) + g(2) = - 25 + 3 = - 22

Answer:

Step-by-step explanation:

Substituting x as -1 in f(x), f(-1)

F(-1)=5(-1)-20

F(-1)=-5-20

F(-1)=-25

Substituting x as2 into g(x), g(2)

G(x) =2^2+5(2)-11

G(x)=4+10-11

G(x)=3

F(-1)+g(2)=-25+3

=-22

Answer: a. 14 Computers

b. 62 Computers

Step-by-step explanation:

a) What is the amount of increase in computers needed?

Number of Computers sold last month = 48

Percentage increase required = 30%

Amount of increase in computers needed= 30% × 48

= 0.3 × 48

= 14.4

= 14 approximately

b)What is the new amount of computers the team must sell?

This will be the amount of Computers sold last month plus the increase.

= 48 + 14

= 62 Computers

The number of different orders that the marbles can be pulled from the bag is 6 ways

If a bag contains one red, one blue, and one yellow, then the total number of marbles contained is 3 marbles.

If the marbles are pulled from the bag one at a time without replacing them, the number of different orders that the marbles can be pulled from the bag is expressed as:
[tex]3C_1=\frac{3!}{(3-2)!} \\3C_1=\frac{3!}{1!}\\ 3C1=3! = 6ways[/tex]

Hence the number of different orders that the marbles can be pulled from the bag is 6 ways

The number of lemonade should Justin give to each person is 7 with one lemonade still left.

It is given that Justin has 64 ounces of lemonade to divide among 9 people.

We have to find out that how much lemonade should he give to each person.

What will be the value of each part , if 120 is divided in 6 equal parts ?

The value of each part will be 120 divided by 6 or 120 ÷ 6 or 20 i.e., 120 is divided into 6 equal parts of 20 each.

As per the question ,

No. of ounces of lemonade to divide among 9 people = 64

No. of lemonade each people will get = 64 ÷ 9

or

64 ÷ 9 = 7.1111

So , we can't equally divide it because if 7 each is divided between 9 people , one lemonade will still be left.

i.e.,

7 × 9 = 63

64 - 63 = 1

1 still left

Thus , the number of lemonade should Justin give to each person is 7 with one lemonade still left.

Answer:

≈206 Minutes

Step-by-step explanation:

We know that the castle has to be guarded for 24 hours a day. Since there are 60 minutes in an hour, that means it must be guarded for 1,440 minutes (60 * 24 = 1,440). If we split this evenly between each of the 7 knights, through division, we know that they must each be on guard for 205.714285714 minutes, or approximately 206 minutes.

The amount by Cesar’s minimum monthly payment increase will be $91.44.

Cesar only has 12 months left before he pays off his credit card completely.

His current balance = $3,750

                       APR = 17.5%

Now we use the formula :

[tex]\rm Present \ value \ of \ anuity= P=( 1-\frac{1+r}{r} })^{-n}[/tex]

PV = Present Value

P   = Periodic payment

r    = rate per period

n   = number of period

Now for the first case:

PV of annuity = $3,750

P =?

r = 17.5% annually = % monthly  monthly

n = 12 months

Now we put the values in the formula

[tex]3750=P(1-\dfrac{(1+\dfrac{17.5}{1200})^{-12}}{\dfrac{17.5}{1200} } )[/tex]

[tex]P=\dfrac{3750}{\dfrac{1-0.8405}{0.01458} }[/tex]

[tex]P=342.91[/tex]

Now for the second Case :

PV of annuity = 3750 + 1000 = 4750

P =?

r = 17.5% annually = % monthly =  monthly

n = 12 months

Putting the values in the formula

[tex]4750=P(1-\dfrac{(1+\dfrac{17.5}{1200})^{-12}}{\dfrac{17.5}{1200} } )[/tex]

[tex]P=\dfrac{4750}{1-\dfrac{1+\frac{17.5}{1200} }{\frac{17.5}{1200} } }[/tex]

[tex]P=\dfrac{4750}{\dfrac{0.1595}{0.01458} } =434.35[/tex]

Cesar's increased monthly payment will be

434.35 - 342.91 = 91.44

Hence, the amount by Cesar’s minimum monthly payment increase will be $91.44.

Answer:

Step-by-step explanation:

Let length be x

So breadth will be 1/4x

2(x+1/4x)=60

x+1/4x=60/2=30

find lcm and the lcm would be 4 and make denominators equal and add it

4/4x+1/4x=30

5/4x=30

x=30*4/50=6*4=24

Therefore the length is 24/4=6cm and breadth is 24cm.

= 16 points

Good luck !

Answer:

marks awarded for each correct answer = 4

marks awarded for each incorrect answer = -2

No.of Sunil's correct answer = 6

therefore, mark of Sunil's correct answer = 6 x 4 = 24

No.of Sunil's incorrect answer = 4

therefore, mark of Sunil's incorrect answer = 4 x -2 = -8 (here + and - is                                                                                                                  multiplied therefore the final answer will be -)

Sunil's total score = 24(positive marks) - 8(negative marks)

                               =24-8 = 16

Answer:

y = (6/5)x + 29/5

Step-by-step explanation:

To avoid confusion please enclose the fractional exponent inside parentheses:  y= -5/6x +3 =>  y= (-5/6)x +3

The new line is to be perpendicular to the given line (above).  The slope of this new line must be the negative reciprocal of (-5/6), which is (6/5).

Usig the slope-intercept formula, we get y = mx + b, or

1 = (6/5)(-4) + b

The LCD here is 5.  Multiplying all 3 terms by 5, we get:

5 = 6(-4) + 5b, or

5 = -24 + 5b, or

5b = 29

Then b = 29/5, and the desired equation is:

y = (6/5)x + 29/5

Answer:

Commutative Property of Addition: to change the order of numbers in an addition or multiplication operation does not change the sum or the product.

New expression with property used: 5(2j + j + 3)

Combine like terms:  when combining like terms, add their coefficients

The like terms are 2j and j.  Add their coefficients: 2 + 1 = 3, which means that the combination of like terms is 3j.

New expression with property used:  5(3j + 3)

Distributive Property of multiplication over addition: multiplying a sum by a number gives the same result as multiplying each added term by the number and then adding the products together.

So 5(3j + 3) = 5 · 3j + 5 · 3 = 15j + 15

New expression with property used:  15j + 15
