First part
Determine 2 points that pass through x + 2y = 5

(i) If x = 1
x + 2y = 5
1 + 2y = 5
2y = 4
y = 2

(ii) If x = 3
x + 2y = 5
3 + 2y = 5
2y = 2
y = 1

Two points that pass through this line are (1,2) and (3,1)

Second part
Determine 2 points that pass through 3x = 15 - 6y

(i) If x = 1
3x = 15 - 6y
3(1) = 15 - 6y
3 = 15 - 6y
6y = 15 - 3
6y = 12
y = 2

(ii) If x = 3
3x = 15 - 6y
3(3) = 15 - 6y
9 = 15 - 6y
6y = 15 - 9
6y = 6
y = 1

Two points that pass through this line are (1,2) and (3,1)

BOTH OF THE LINE pass through the same two points, that means the lines are the same because they overlap. Look at the attachment.

A particle is projected at a speed of 12 ms^-1 up a straight inclined track. Whilst on the
seraphim [82]

The time taken for the particle to travel more than 8 meters from the point of projection is 0.59 s.

<h3>Time of motion of the particle</h3>

The time taken for the particle to travel more than 8 meters from the point of projection is calculated as follows;

s = v₀t + ¹/₂at²

8 = 12t + (0.5 x 5)t²

8 = 12t + 2.5t²

2.5t² + 12t  - 8 = 0

solve the equation using formula method

t = 0.59 s

Thus, the time taken for the particle to travel more than 8 meters from the point of projection is 0.59 s.

1-sin60÷cos60=1-Tan30÷1+Tan30
ipn [44]

Step-by-step explanation:

LHS=(1-sin60)/cos60

=(1-√3÷2)/1÷2

=2(1-√3÷2)

=2-√3

RHS=(1-tan30)/(1+tan30)

={1-(1÷√3)}/{1+(1÷√3)}

={(√3-1)/√3}/{(√3+1)/√3}

=(√3-1)/(√3+1)

={(√3-1)(√3-1)}/{(√3+1)(√3-1)}

=(3-√3-√3+1)/(3-1)

=(4-2√3)/2

=2-√3

Therefore LHS=RHS
