Step-by-step explanation:

Answer:

b. 25

Step-by-step explanation:

To have an infinite number of solutions, both equations must be equal.

-2x + 5y = 23

-10x + ky = 115

Multiply both sides of the first equation by 5 and write it. Rewrite the second equation below the first equation.

-10x + 25y = 115

-10x + ky = 115

For the equations to be equal, you must have

25y = ky

Divide both sides by y.

k = 25

The conclusion is that the expression [tex]\lim_{x \to \infty} \frac{6 (2^x) - 1}{5x^2+ 10}[/tex] cannot be solved  without the l'hopital's rule,

The limit expression is given as:

[tex]\lim_{x \to \infty} \frac{6 (2^x) - 1}{5x^2+ 10}[/tex]

The limit of the expression cannot be solved without l'hopital's rule, because a direct substitution of ∞ for x would result in the following expression ∞/∞

i.e.

[tex]\lim_{x \to \infty} \frac{6 (2^{\infty}) - 1}{5(\infty)^2+ 10} = \frac{\infty}{\infty}[/tex]

So, the best way is to apply the l'hopital's rule.

This is done as follows:

[tex]\lim_{x \to \infty} \frac{f(x)}{g(x)} = \lim_{x \to \infty} \frac{f'(x)}{g'(x)}[/tex]

When the numerator and the denominator are differentiated, we have:

[tex]\lim_{x \to \infty} \frac{f(x)}{g(x)} = \frac{3\ln(2)\cdot 2^{x + 1}}{10x}[/tex]

Further, differentiate

[tex]\lim_{x \to \infty} \frac{f(x)}{g(x)} = \frac{3\ln^2(2)\cdot 2^{x + 1}}{10}[/tex]

Now, we can substitute [tex]\infty[/tex] for x

[tex]\lim_{x \to \infty} \frac{f(x)}{g(x)} = \frac{3\ln^2(2)\cdot 2^{\infty + 1}}{10}[/tex]

Evaluate the numerator

[tex]\lim_{x \to \infty} \frac{f(x)}{g(x)} = \frac{\infty}{10}[/tex]

Evaluate the quotient

[tex]\lim_{x \to \infty} \frac{f(x)}{g(x)} = \infty[/tex]

Hence, the conclusion is that the expression [tex]\lim_{x \to \infty} \frac{6 (2^x) - 1}{5x^2+ 10}[/tex] cannot be solved  without the l'hopital's rule

Answer: 318 km²

Let's find the areas of the triangles

Formula: base x height / 2

9 x 6 = 54

54/2 = 27

Multiply by 2 since there are two triangles (I know, we already got the areas from 9 x 6)

27 x 2 = 54

Now let's try to find the areas of all the rectangular sides

Formula: length x width

9 x 11 = 99

8 x 11 = 88

7 x 11 = 77

99 + 88 + 77 = 264

Add up all the areas

264 + 54 = 318

Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol '%' is used to symbolize it.

At a breakfast buffet, 63% of people choose coffee as their beverage while 23% choose juice.

Also, 20% choose both coffee and juice.

Then the percentage of people who chose only coffee will be given by the difference of 63% and 20%.

⇒ 63% - 20%

⇒ 43%

Thus, the percentage of people who chose only coffee will be 43%.

Step-by-step explanation:

The product of 7 and 2 basically means you multiply them. The product of 7 and 2 is 14 and the product of 8p cannot be known because p is undefined so keep it as 8p. the product of 14 and 8p is 112p but the answer I stated above is the unsimplified version.

Answer:

apples = 160

oranges = 100

Step-by-step explanation:

Let apples be x and oranges be y

so

x = 60+y

now he have

y = x + 20

y-20 = x

(60+y)/2 = y-20

60+y = 2y-40

60+y-2y = -40

or, 60-y = -40

or, 60+40 = y

or, y = 100

so, y = 100

now, x = 60+100

so, x = 160

Answer:

100 oranges

160 apples

Step-by-step explanation:

Initially let x = oranges, so apples = x + 60

He sells 1/2 the apples which is (x + 60)/2, then there are 20 more oranges than apples so x (the oranges) will = the remaining apples (x + 60)/2 plus 20 OR

x = (x + 60)/2 + 20 multiply each term by 2 to get rid of the denominator

2x = (x + 60) + 40

2x - x = 60 + 40

x = 60 + 40 = 100 oranges AND

x + 60 or 160 apples

Answer:

8

Step-by-step explanation:

1. 5/5+7=?

The fraction means divide, so you divide 5 by 5. When you divide a number by the same number, it equals one. So 5 divided by 5 equals 1.

2. 1+7=?

The next step after dividing the fraction is you add the two numbers together. so 1 plus 7 equals 8.

16x -7 =$13.32

Step-by-step explanation:

$13.32 + $7 = $20.32

$20.32 divided by 16 = $1.27

each cookie cost $1.27

I really hope this help

Answer:- 16x - 7 = 13.32

Also cost of each cookie = $1.27

Explanation:

Let the cost of each cookies be x

ATQ

16x -7 = 13.32

We will mutiply x with 16 because he purchased 16 cookies.

Also he had coupon of $7 which means $7 off which is why -7

And 13.32 is the amount he paid

Now lets solve it

16x - 7 = 13.32

16x = 13.32 + 7

16x = 20.32

x = 20.32/16

x = 1.27

Therefore cost of each cookie is $1.27

Answer:

m/_EFG= -5 and m/_GFH= 5

Step-by-step explanation:

set the linear equations equal to eachother so that it looks like

2n+23=3n+37 then you have to combine like terms by rearranging the equations. you move the numbers by canceling them out. and what you do to one side must be done to the other. after you do this the equation should look like this.

2n - 3n = -23 + 37

then finish combining the terms

-1n = 14

then divide to get -14

the final step is to plug -14 back into your original equations in the place of n. then you solve to get your answer.

2 x -14 + 23 = -5 and 3 x -14 + 37 = 5
