[tex](x - 7)(x - 5) = 3[/tex]
​

Answers

Answer 1

Answer:

x = 4, x = 8

Step-by-step explanation:

Given

(x - 7)(x - 5) = 3 ← expand factors using FOIL

x² - 12x + 35 = 3 ( subtract 3 from both sides )

x² - 12x + 32 = 0 ← in standard form

(x - 4)(x - 8) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 8 = 0 ⇒ x = 8

In 1995, there were 85 rabbits in Central Park. The population increased by 12% each year. How many rabbits
populated Central Park 21 years later?

Answers

Answer:

918

Step-by-step explanation:

Given data

Initila population= 85

Rate = 12%

TIme= 21 years

Let us apply the compounding expression

A=P(1+r)^t

substitute

A= 85(1+0.12)^21

A=85(1.12)^21

A=85*10.80

A= 918

Hence the approximate Rabbit population will be 918

A corner store sells two kinds of baked goods: cakes and pies. A cake costs $15 and a pie costs $13. In one
day, the store sold 9 baked goods for a total of $121. How many cakes did they sell?
a. 8 cakes
c. 7 cakes
b. 2 cakes
d. 4 cakes

Answers

Answer:

a. 8

Step-by-step explanation: Out of  12   baked goods sold , let the number of cakes sold, be  x  in number and pies sold were  12 − x  in number. Total sell was  $ 144  ,  1  cake costs  $ 14  and  1  pie costs, $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96  or 6 x = 48 ∴ x = 8

An initial population of 490 quail increases at an annual rate of 6%. Write an exponential
function to model the quail population. What will the approximate population be after 5 years?

Answers

Answer:

656

Step-by-step explanation:

Given data

Initila population= 490

Rate = 6%

TIme= 5 years

Let us apply the compounding expression

A=P(1+r)^t

substitute

A= 490(1+0.06)^5

A=490(1.06)^5

A=490*1.338

A= 655.62

Hence the approximate Quail population will be 656

Work out the m and c for the line
y=x+6

Answers

Answer:

m - 1

c - 6

Step-by-step explanation:

[tex]y=x+6\\\\[/tex]

The equation is in slope-intercept form.

y = mx + c

m - slope

c (or b) - y -intercept

Usually if the slope is one it will not be written.

y = 1x + 6  

The slope is one.

6 takes 'c's place, so it is the y-intercept.

Hope this helps.

Given the triangles are similar, find y.

Answers

Answer:

y = 8

Step-by-step explanation:

(y + 4) ÷ y = 1.5

y + 4 = 1.5 y

0.5 y = 4

y = 8

The total number of victories for a football team exceeds the number of defeats by 4, with no draws. Knowing that if 44 jojos, how many victories were there?

Answers

Answer: 24

Step-by-step explanation:

Let the number of defeats be represented by x.

Since the total number of victories exceeds the number of defeats by 4, then the number of victories will be:

= x + 4

We then add the number of victories and losses together and equate them to 44. This will be:

x + x + 4 = 44

2x + 4 = 44

2x = 44 - 4

2x = 40

x = 40/2

x = 20

Therefore number of victories will be:

= x + 4

= 20 + 4

= 24

2.42*3.20 step by step

Answers

Answer:

7.744

Step-by-step explanation:

3.20=3.2

you can multiply just 242 and 32 then pop in the decimal point later

242*32=242*30 + 242*2

242*3*10=726*10=7260

242*2=484

7260+484=7744

2*3 (rounded version of numbers) is 6

so the answer after putting decimal point should be around 6

77.44 is way too hight

7.744 is decently close to 6

so the answer is 7.744

its 4.55 because 4.5 is simple 4.50, so, 4.55 is 0.05 bigger than 4.5

4.55 is bigger. If we add a zero to 4.50 that’s just 4 dollars and 50 cents and if we do that to 4.55 that’s 4 dollars and 55 cents which is 5 cents more.

Step-by-step explanation:

I just wanted to let you know.

Answer:

2 3/4

- 3/7

 3 5/28

Step-by-step explanation:

First, Find the common denominator of 4 and 7 which is 28. 28 will be the denominator of your difference.Then, now time to multiply, now you multiply 7 by 21 because you multiplied 7 by 4  to get 28. You do the same for the others one but a bit different because this time you multiply 4 by 3= 12 now you have 21/28 and 12/28. Now you add 21 and 12 not 28 because you don't multiply denominators in this case. After that you get 33/28, this is an improper fraction so you divide. 28 goes into 33 once so you have a whole number 1 then you have 5 left over making it the numerator. Result 1 5/28, because you have the whole number 2 left from the equation you add it ending up with 3 5/8

Hope this helps :D !!    

Help? which one should I choose

Answers

Answer:

true

Step-by-step explanation:

For 3 sides to be able to form a triangle, we need to check that the 2 shorter sides can "touch" when "stemming" out of the long side.

The long side has length 7cm, so the sum of 2 shorter sides must be bigger than 7cm for them to "touch". Note: if the sum was 7cm, the only way they would touch is if they were laid along the long side, so it would not be a triangle - it would be a segment.

Fortunately, 3cm + 5cm > 7cm, so we can form a triangle.

A rake for scraping up muck or dungMuckrake- v. To search out and publicly expose real or apparent misconduct of a prominent individual or businessSATURDAY, APRIL 14, 1906In Bunyan's Pilgrim's Progress you may recall the description of the Man with the Muck-rake, the man who could look no way but downward, with the muck-rake in his hand; who was offered a celestial crown for his muck-rake, but who would neither look up nor regard the crown he was offered, but continued to rake to himself the filth of the floor.In Pilgrim's Progress the Man with the Muck-rake is set forth as the example of him whose vision is fixed on carnal instead of on spiritual things. Yet he also typifies the man who in this life consistently refuses to see aught that is lofty, and fixes his eyes with solemn intentness only on that which is vile and debasing. Now, it is very necessary that we should not flinch from seeing what is vile and debasing. There is filth on the floor and it must be scraped up with the muck-rake; and there are times and places where this service is the most needed of all the services that can be performed. But the man who never does anything else, who never thinks or speaks or writes, save of his feats with the muck-rake, speedily becomes, not a help to society, not an incitement to good, but one of the most potent forces for evil.There are, in the body politic, economic and social, many and grave evils, and there is urgent necessity for the sternest war upon them. There should be relentless exposure of and attack upon every evil man whether politician or business man, every evil practice, whether in politics, in business, or in social life. I hail as a benefactor every writer or speaker, every man who, on the platform, or in book, magazine, or newspaper, with merciless severity makes such attack, provided always that he in his turn remembers that the attack is of use only if it is absolutely truthful. . . To assail the great and admitted evils of our political and industrial life with such crude and sweeping generalizations as to include decent men in the general condemnation means the searing of the public conscience. There results a general attitude either of cynical belief in and indifference to public corruption or else of a distrustful inability to discriminate between the good and the bad. Either attitude is fraught with untold damage to the country as a whole. The fool who has not sense to discriminate between what is good and what is bad is well-nigh as dangerous as the man who does discriminate and yet chooses the bad. There is nothing more distressing to every good patriot, to every good American, than the hard, scoffing spirit which treats the allegation of dishonesty in a public man as a cause for laughter. Such laughter is worse than the crackling of thorns under a pot, for it denotes not merely the vacant mind, but the heart in which high emotions have been choked before they could grow to fruition.In this speech Roosevelt states, "There is nothing more distressing to every good patriot, to every good American, than the hard, scoffing spirit which treats the allegation of dishonesty in a public man as a cause for laughter." What else could Roosevelt say to strengthen his position? False accusations of bad character could lead to war. Journalists have a responsibility to protect the government. Poor journalism results in public disinterest. The attempt to make money from attacks on character is immoral. f(x)=2 |x+5| - 8vertex = (-5, -8)what is the line of symmetry? DD.
