Answer:

3/20

Step-by-step explanation:

1/1-1/4-3/5= (money spent)

1×4×5/(1×4×5)-1×1×5/(1×4×5)-3×1×4/(1×4×5)

20/20-5/20-12/20

(20-5-12)/20=3/20

Given that y is directly proportional to x. If y = 30 and x= 5, write an equation that connects y with x.
Licemer1 [7]

Given:

y is directly proportional to x.

y=30 when x=5

To find:

The equation that connects y with x.

Solution:

It is given that, y is directly proportional to x. So,

y\propto x

y=kx                     ...(i)

Where, k is the constant of proportionality.

We have, y=30 when x=5. Substituting these values in (i), we get

30=k(5)

Divide both sides by 5.

\dfrac{30}{5}=k

6=k

Substituting k=6 in (i), we get

y=6x  

Therefore, the required equation is y=6x.

If g(x) = 3x - 4, what is the value of g-^1(g(13))?
Aliun [14]
• g^-1

y = 3x – 4

3x = y + 4

x = y + 4 / 3

g^-1 = x + 4 / 3

• g(13)

3(13) – 4

39 – 4

g(13) = 35

• g^-1(g(13)) = (35) + 4 / 3

39 / 4

g^-1(g(13)) = 13

Based on the type of equations in the system, what is the greatest possible number of solutions? StartLayout Enlarged left-brace
krok68 [10]

Answer:

2

Step-by-step explanation:

Given the system of equations:

x^2+y^2=9\\9x+2y=16

Comparing x^2+y^2=9 with the general standard equation of a circle (x-h)^2+(y-k)^2=r^2.

The first equation is an <u>equation of a circle centred</u> at (0,0) with a Radius of 3.

The second equation 9x+2y=16 is a <u>straight line equation.</u>

A straight line can only intersect a circle at a maximum of 2 points.

Therefore the greatest possible number of solutions to the equations in the system is 2.
