d = b - 3 / 10

Step-by-step explanation:

b = 10d + 3

Place +3 in the other side of the equal sign
+ 3 becomes - 3
b - 3 = 10
Divide both sides by 10 to make d the subject
b - 3 / 10 = 10d / 10
d = b - 3 / 10

Not parallel to y=6x+2

bija089 [108]

Hello there! A line that is not parallel to the line given, y = 6x+2, would have a slope value other than 6.

This is because any lines with the same slope and different y-intercepts are parallel to each other, so for them to be not parallel, the slopes would have to be different.

Hope this helps, and have a great day! :)

Air traffic controller Seymour Plains must quickly calculate the altitude of an incoming jet. He records the jet’s angle of elev

Liono4ka [1.6K]

Answer:

Altitude of the jet is 10.40km

Step-by-step explanation:

The angle of elevation = 8°

Horizontal distance (adjacent to the angle) = 74km

Altitude of the plane (opposite) = ?

Kindly check attached document for better illustration.

To solve this question, we have to use tangent rule since we have adjacent and angle, but no opposite.

Tanθ = opposite / adjacent

θ = 8°

Adjacent = 74km

Opposite = ?

Tan 8 = x / 74

Opposite = 74 * tan8

Opposite = 10.40

The altitude of the jet is 10.40km
