find the point of intersection of the pair of straight lines.
10x - 4y = 43
-3x - 3y = -15
(x, y) = ( , )

(x,y) = (,)

Step-by-step explanation:

We have to find point of intersection of two lines.

the given equations of line are:

10x - 4y = 43 - (1)

-3x - 3y = -15 - (2)

Multiplying the first equation by 3 we have:

(10x - 4y = 43)×3 = 30x - 12 y = 129 - (3)

Multiplying second equation by 10 we have :

(-3x - 3y = -15)×10 = -30x -30y = -150 - (4)

Now, adding equation (3) and (4)  we have:

-42y = -21

⇒ y =

Now, putting this value of y in equation (1), we have

10x - 2 = 43

⇒ 10x = 45

⇒x =

Hence, the intersection of given two lines is (x,y) = (,)

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
