What is the result of adding these two equations?
andre [41]

Answer:

x=103/265        y=18/53

Step-by-step explanation:

5x -9y=1-----------(i)

-7x+2y=-5-----------(ii)

Multiplying eq 1 with 7 gives

35x-63y=7---------eq(iii)

Multiplying eq 2 with 5 gives

-35x+10y=-25--------eq(iv)

adding eq 3 qnd eq 4

35x-63y-35x+10y=7-25

-53y=-18

y=18/53--------eq5

Putting the value of y from eq 5 in eq 1

5x-9(18/53)=-5

5x- 162/53=-5

5x=-5 +162/53

5x= -265+162/53

5x=103/53

x=103/265

Gym membership costs $100 per year in a $2 fee per visit another gem charges $12 fee per visit with no yearly membership find th
Nimfa-mama [501]

Answer:

<em>For 10 visits, both gyms charge the same</em>

Step-by-step explanation:

<u>Equations</u>

Gym memberships' costs are:

G1 = 100 + 2x

G2 = 12x

Where x is the number of visits to the gym.

We need to find the number of visits for which the charges for both gyms are the same. Thus equating the costs:

12x = 100 + 2x

Subtracting 2x:

10x = 100

Dividing by 10:

x =10

For 10 visits, both gyms charge the same

<u>Step-by-step explanation:</u>

The intersection of the circle will result in either Tangent or Secant. Secant is a line intersecting a circle at two different point. This concept explains the relation between the circle and line intersecting it.

From the given diagram,

The \vec{GJ} and \vec{GK} intersects the circle at the point H and I.

∴ It can also represented that the \vec{JH} and \vec{KI} intersects at a point G.

From the given options \vec{KI} is the secant line that intersects the circle twice.
