I think it is 6 sorry if it is wrong

Step-by-step explanation:

;-;

Answer:

Since 3^5 is equal to 243, that means if you were to evaluate 3^5, the answer would be 243. That means it would be very easy to evaluate as the answer is already stated to be equal to 243.

Answer:

(3, 2 )

Step-by-step explanation:

Given the 2 equations

4x + y = 14 → (1)

5x + 2y = 19 → (2)

Multiplying (1) by - 2 and adding to (2) will eliminate the y- term

- 8x - 2y = - 28 → (3)

Add (2) and (3) term by term to eliminate y

- 3x + 0 = - 9

- 3x = - 9 ( divide both sides by - 3 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

4(3) + y = 14

12 + y = 14 ( subtract 12 from both sides )

y = 2

solution is (3, 2 )

Step-by-step explanation:

[tex] \underline{ \underline{ \text{USING \: ELIMINATION \: METHOD}}}[/tex]

[tex] \underline{ \underline{ \text{ Solution}}} : [/tex]

Multiply equation ( i ) by 2 & Subtract from ( ii ). The equation ( i ) now becomes 8x +2y = 28 { 2 ( 4x + y ) = 2 × 14 }. Remember that while subtracting the sign of each term of equation ( i ) changes and now , it becomes -8x-2y = -28.

[tex] \text{5x + 2y = 19}[/tex]

[tex] \text{ - 8x - 2y = - 28}[/tex]

_____________________

[tex] \text{ - 3x = - 9}[/tex]

Solve for x :

⤑ [tex] \tt{x = \frac{ - 9}{ - 3}} [/tex]

⤑ [tex] \tt{x = 3}[/tex]

Now , substitute the value of x in equation ( ii ) :

⟼ [tex] \text{5 × \: 3 + 2y = 19}[/tex]

⟼ [tex] \text{15 + 2y = 19} [/tex]

⟼ [tex] \text{2y = 19 - 15}[/tex]

⟼ [tex] \text{2y = 4}[/tex]

⟼ [tex] \text{y = 2}[/tex]

[tex] \pink{ \boxed{ \boxed{ \tt{⤿ \: Our \: final \: answer : \boxed{ \boxed{ \tt{x = 3 \: and \: y = 4}}}}}}}[/tex]

Answer:

VW = 29

Step-by-step explanation:

Perimeter of the triangle = 82

Perimeter of the triangle = 4x + (x + 3) + (3x - 1)

4x + (x + 3) + (3x - 1) = 82

4x + x + 3 + 3x - 1 = 82

8x + 2 = 82

8x = 82 - 2

8x = 80

x = 10

VW = 3x - 1

VW = 3(10) - 1

VW = 30 - 1

VW = 29

Answer: B) -1/3i

Step-by-step explanation: 81(-1/3i)^4

Answer:

Step-by-step explanation:

81x^4=1

x^4=1/81

(x^4)^(1/4)=(1/81)^(1/4)

x=+\-1/3

so -1/3 is a solution

Answer:

horizontal asymptote at

y

=

0

Step-by-step explanation:

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non-zero for these values then they are vertical asymptotes.

solve:

Horizontal asymptotes occur as

Oblique asymptotes occur when the degree of the numerator > degree of the denominator. This is not the case here (numerator-degree 1 , denominator-degree 2) Hence there are no oblique asymptotes.

Answer:

[tex]-21a^{3}+12a[/tex]

Step-by-step explanation:

We are given that

[tex]-3a\cdot (7a^2-4)[/tex]

We have to find the product .

To find the product we will multiply -3a with each term given in the bracket

[tex]-3a(7a^2)-3a(-4)[/tex]

[tex]-21a^{1+2}+12a[/tex]

By using the formula

[tex]a^{x}\cdot a^{y}=a^{x+y}[/tex]

[tex]-21a^{3}+12a[/tex]

Hence,

[tex]-3a\cdot (7a^2-4)=-21a^{3}+12a[/tex]

Answer:

y = -3x + 5

Step-by-step explanation:

For two lines to be perpendicular, the product of their slope must be -1.

Slope of the given line M = 1/3

Slope of the required line is m

If product is -1, then;

Mm = -1

1/3 m = -1

m = -3

SInce it intersects at the y intercept, y intercept c = 5

Get the required equation. Substitute m = -3 and c = 5 into the equation

y = mx+c

y = -3x + 5

Hence the required equation of the line is y = -3x + 5

Answer:

[tex]s = \frac{1}{5}t - \frac{4}{5}[/tex]

Step-by-step explanation:

Subtract 4 and divide by 5 to obtain

[tex]t=5s + 4\\s = \frac{t-4}{5}\\s = \frac{1}{5}t - \frac{4}{5}[/tex]

Answer:

Yes

Step-by-step explanation:

g(x) = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{1}{4}[/tex]

y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{1}{4}[/tex] ....... (1)

(1) × 4

4y = - x + 1

x = - 4y + 1

y = - 4x + 1

f(x) = - 4x + 1

∴ f(x) and g(x) are inverses

umm i dont knowe sorry

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that:

Principal = $650

Interest rate, r = 2.3% = 0.023 compounded daily

Time, t it takes for final amount, A to reach $880

Using the relation :

A = P(1 + r/n)^nt

n = number of times compounded per period

Hence, n = 365

880 = 650(1 + 0.023/365)^365t

880/650 = 1.0000630^365t

1.3538461 = 1.0000630^365t

Take the log

0.1315692 = 0.0000273596 * 365t

0.1315692 = 0.0099862t

t = 0.1315692 / 0.0099862

t = 13.175101

t = 13.18 years a

Answer: 11.5 feet

Step-by-step explanation:

We should note that for a right angles triangle, the square of the hypothenuse equals to the square of the opposite side and its adjacent. This can be expressed as:

Let the length of Fahims shadow be x

hypotenuse² = opposite² + adjacent ²

13² = 6² + x²

169 = 36 + x²

x² = 169 - 36

x² = 133

x =✓133

x = 11.53

= 11.5 feet to nearest tenth

Step-by-step explanation:

Given :

The scale of a model train is 1 inch to 13.5 feet.

One of the cars of the model train is 5 inches long.

To Find :

The length, in feet, of the actual car.

Solution :

It is given that scale of the model is 1 inch to 13.5 feet. It means that 1 inch in the actual scale is equal to 13.5 feet in real.

So, length of car real is :

Length = 5 × 13.5 feet

Length = 67.5 feet

Therefore, the length of the actual car is 67.5 feet.

Answer:

$6

Step-by-step explanation:

B- 3P+2C=$41

C-1P+2C=$29

since they both bought at least 1 popcorn and 2 candy you can just subtract 29 from 41. you get 12 which equals the other 2 popcorns that ben bought

12/2=6

since you need to find the price of 1 popcorn you have to divide 12 by 2

Answer:

photo albums = x

pictures =75( seven times of albums +5)

so

seven times of x is 7x and +5

7x +5 = 75

7x= 75-5

7x = 70

x=70÷7

x =10

x = 10 = photo albums
