Answer:

question 7: irrational.

Question 8: rational.

Step-by-step explanation:

Answer:

y = -7/3x + 5

Step-by-step explanation:

7x + 3y = 15

- subtract 7x from both sides

3y = -7x + 15

- divide both sides by 3

y = -7/3x + 5

Answer:

p = $12,000

c = $4,500

b = $3,000

Step-by-step explanation:

Denote the variables as follows:

p = amount borrowed from parents

c = amount borrowed from the credit union

b = amount borrowed from the bank

The equations that can be formed using the given information are as follows:

p + c + b = 19500... (i)

p = 4b... (ii)

The formula to compute simple interest is:

SI = P × (R/100) × T

So, the equation for the total interest paid at the end of 1 year is:

0.05p + 0.04c + 0.03b = 870

5p + 4c + 3b = 87000... (iii)

Substitute (ii) in (i) and (iii) and simplify as follows:

4b + c + b = 19500

⇒ c + 5b = 19500... (iv)

5(4b) + 4c + 3b = 87000

⇒ 4c + 23b = 87000... (v)

Subtract (iv) from (v):

4c + 23b = 87000

(-)c + (-)5b = (-)19500 ] × 4

⇒

4c + 23b = 87000

-4c - 20b = -78000

⇒

3b = 9000

b = 3000

Compute the value of p as follows:

p = 4b = 4 × 3000 = 12000

p = 12000

Compute the value of c as follows:

p + c + b = 19500

12000 + c + 3000 = 19500

c + 15000 = 19500

c = 4500

Thus, the amount borrowed from each source is:

p = $12,000

c = $4,500

b = $3,000

Answer:

Domain : (-∞,∞)

Range : (-∞,∞)

Step-by-step explanation:

Domain is how many x-values the graph touches and Range is how many y-values the graph touches. And this graph has no point on which it stops nor any asymptotes, so both domain and range are all real numbers.

Answer:

Step-by-step explanation:(F)=1/F+6

We move all terms to the left:

(F)-(1/F+6)=0

Domain of the equation: F+6)!=0

F∈R

We get rid of parentheses

F-1/F-6=0

We multiply all the terms by the denominator

F*F-6*F-1=0

We add all the numbers together, and all the variables

-6F+F*F-1=0

Wy multiply elements

F^2-6F-1=0

a = 1; b = -6; c = -1;

Δ = b2-4ac

Δ = -62-4·1·(-1)

Δ = 40

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

F1=−b−Δ√2aF2=−b+Δ√2a

The end solution:

Δ‾‾√=40‾‾‾√=4∗10‾‾‾‾‾‾√=4√∗10‾‾‾√=210‾‾‾√

F1=−b−Δ√2a=−(−6)−210√2∗1=6−210√2

F2=−b+Δ√2a=−(−6)+210√2∗1=6+210√2

Answer:

look for the LCM of all the denominators, devide the denominators by the LCM and add the numerators( don't forget the signs ), then add and subtract your answers ( by this time the LCM becomes the denominator and the answer from th subtraction and addition of the numerators becomes the present numerator ), then reduce to lowest term the answer gotten

Answer:

[tex]\sqrt3[/tex]

Step-by-step explanation:

I'm assuming you're dealing with degrees.

If that's the case, then I would first find the closest multiple of 360 to that number.

360*20 = 7200, which is a bit too high; 360*19 = 6840, still a bit too high; 360*18 = 6480, perfect.

Now, just subtract 6480 from 6720 and you will get 240.

The answer is now simplified to tan 240, which can be expressed as sin(240)/cos(240).

240 degrees is 30 degrees away from 270, creating a 30-60-90 triangle.

That means cos(240) is -1/2 and sin(240) is -sqrt(3)/2.

Now, just divide:

[tex]-\frac{\sqrt3}{2}/-\frac{1}{2} = -\frac{\sqrt3}{2}\cdot-2 = \sqrt{3}[/tex]

Therefore, tan(6720 degrees) = [tex]\sqrt3[/tex]
