does anybody know this????

Answer:

(f - g)(x) = -x² + 3x + 7 ⇒ D

Step-by-step explanation:

In the expression x - a, you will subtract a from x

Let us solve the question using this fact

f(x) = 3x + 1

g(x) = x² - 6

→ We need to find (f - g)(x), which means subtract g from x

∵ (f - g)(x) = (3x + 1) - (x² - 6)

→ The negative sign before (x² - 6) will change their signs

∵ - (x² - 6) = -(x²) + -(-6)

→ Remember (-)(+) = - and (-)(-) = (+)

- (x² - 6) = -x² + 6

→ Substitute it in (f - g)(x)

∴ (f - g)(x) = 3x + 1 - x² + 6

→ Add the like terms

∴ (f - g)(x) = 3x - x² + (1 + 6)

∴ (f - g)(x) = 3x - x² + 7

→ Re-arrange the terms from the greatest power of x

(f - g)(x) = -x² + 3x + 7

Solve for x.

-x + 4 = 32

1. x = 36
2. x = 28
3. x = -28
4. x = -36

Answers

Answer:

x=-28

Step-by-step explanation:

-x+4=32

-x=32-4

-x=28

x= -28

Answer is x=-28 because 32-4 is 28 then you divide by -1 because you can’t have a -x so it’ll be -28

How much is the number 727731000 in percent form




I need yall to answer this question quickly you will recieve a ton of points if you do.

Answers

Answer:

72773100000%

Step-by-step explanation:

"Percent" means "per 100" or "over 100". So, to convert 727731000 to percent we rewrite 727731000 in terms of "per 100" or over 100.

Multiply 727731000 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

7277310001×100100=72773100000100

72773100000/100 is 72773100000 over 100 and means 72773100000 per 100. 72773100000 "per 100" means 72773100000 "percent" or 72773100000%

Therefore, we have shown that

727731000 = 72773100000%

Simplified Conversion:

Multiply by 100 and add the percent sign %

727731000 × 100 becomes 72773100000%

Shortcut Conversion:

Move the decimal point 2 places to the right and add the percent sign %

727731000 becomes 72773100000%

727731000% because your just putting it over a 100.

Answers

Answer:

Total Amount spent on all the cards = $ 42.3

No of cards  = 16 .

Step-by-step explanation:

The cost is calculated by multiplying the number of items with their costs. As we have different costs for each card we will add the costs of different cards to get the total costs.

Janet buys 3 postcards for $1.05.

Janet spends 3* $1.05= $ 3.15

Rosie buys five postcards for $1.75

Rosie spends 5 * $ 1.75= $ 8.75

Tanya buys eight postcards for $3.80

Tanya spends 8 * $3.80 = $ 30.4

Total Amount spent on all the cards = $ 3.15+$ 8.75+$ 30.4= $ 42.3

No of cards = 3 + 5+ 8= 16 cards were bought .

. If the difference between a number and its reciprocal is 24/5, find the number.​

Answers

Answer:

The answer is 5/25 you just switch it

Answer:

number is 5

Step-by-step explanation:

The reciprocal of a number n is [tex]\frac{1}{n}[/tex] , thus

n - [tex]\frac{1}{n}[/tex] = [tex]\frac{24}{5}[/tex]

Multiply through by 5n to clear the fractions

5n² - 5 = 24n ( subtract 24n from both sides )

5n² - 24n - 5 = 0 ← in standard form

(n - 5)(5n + 1) = 0 ← in factored form

Equate each factor to zero and solve for n

n - 5 = 0 ⇒ n = 5

5n + 1 = 0 ⇒ 5n = - 1 ⇒ n = - [tex]\frac{1}{5}[/tex]

However, n > 1 , thus n = 5

That is the number is 5

Answer:⬇️

Step-by-step explanation:

Reorder 5 5 and 5x 5 x . Using the slope-intercept form, the slope is 5 . The equation of a perpendicular line to y=5x+5 y = 5 x + 5 must have a slope that is the negative reciprocal of the original slope.

Waich of the following is a true statement about perpendicular lines?
A. Perpendicular lines intersect to form a 45° angle.
B. Perpendicular lines can also be parallel lines.
C. Perpendicular lines cannot be parallel to each other.
D. Perpendicular lines intersect in at least two points.

Answers

Answer:

C

Step-by-step explanation:

perpendicular lines intersect at a 90 degree angle, meaning it is not answer choice A.

B is incorrect because perpendicular lines intersect, so they can not be parallel.

C is correct because parallel lines never intersect, so perpendicular lines can never be parallel to each other.

D is incorrect because perpendicular lines only intersect at one point and create four consistent right angles.

The art club is raising money for a new equipment. They need $842.36 to purchase new supplies and have received a $300.00 donation. The remaining amount will be equally divided among 4 different fundraisers throughout the summer. How much money will each fundraiser need to raise in order to purchase the new net and equipment?

Answers

Answer: Each fundraiser need to raise $ 135.59  in order to purchase the new net and equipment.

Step-by-step explanation:

Money required = $ 842.36

Donation amount = $ 300.00

Amount left to arrange  =  (Money required - Donation amount )

= $ (842.36- 300.00)

=  $ 542.36

Number of fundraisers = 4

Money required to arrange by each fundraiser = (Amount left to arrange) ÷4

= $ (542.36÷4)

= $ 135.59

Hence, each fundraiser need to raise $ 135.59  in order to purchase the new net and equipment.
