Answer:

Step-by-step explanation:

yes....the pair of linear equations has unique solution.....

2x + 3y - 7 = 0 ...... (i)

3x + 2y + 10 = 0 ....... (ii)

on comparing the equation i nd ii with a1x + b1y + c1 = 0

nd a2x + b2y + c2 = 0 reslectively......

a1 = 2 ; b1 = 3 ; c1 = -7

a2 = 3 ; b2 = 2 ; c2 = 10

here....its clear that......

a1 / a2 is not equal to b1 / b2

Therefore the given pair of linear equation have a unique solution........

Distance between points \left(x_1,y_1\right) and \left( x_2,y_2 \right) is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

Distance from H to B:

[tex]d=\sqrt{(10-(-3))^2+(1-(-9))^2}=\sqrt{169+100}=\sqrt{269}d=\sqrt{(1-(-3))^2+(10-(-9))^2}=\sqrt{16+361}=\sqrt{376}[/tex] units.

Distance from Z to B:

d=\sqrt{(10-(-3))^2+(1-(-9))^2}=\sqrt{169+100}=\sqrt{269} units.

Horse Z is closer to the barn.

(The conversion to meters is not required; the question does not ask for actual distances, so "units" is OK.)

1. Find the value of x. The diagram is not to scale. Lines F and G are parallel.
Rus_ich [418]

(1)

we are given that

f and g are parallel lines

so, sum of both angles must be 180

5x+9x+26=180

now, we can solve for x

14x+26=180

Subtract both sides by 26

14x+26-26=180-26

14x=154

x=11...........Answer

(2)

we are given that

l and m are parallel lines

so, alternate angles must be equal

so, we get

x=28...........Answer
