Answer:
y=9-7x
If x= -1, y=16
If x= 0, y=9
If x=2, y= -5
Step-by-step explanation:
Because you are solving the equation for y, you want to have y by itself on one side. The only way to do that in this problem is by subtracting the 7x on both sides.
y+7x=9
-7x -7x ---> y=9-7x
The next part of the question says to find the value of Y for each value of X. Using the given X values, we plug them into the equation we just got in order to find Y.
y=9-7(-1) ----> y=16
y=9-7(0) ----> y=9
y=9-7(2) ----> y=-5

Answer:
135 degrees
Step-by-step explanation
Consider the attached diagram
we are required to find the bearing of the aeroplane,
Consider the right angled triangle BOE
|OB|=4 unit
|AB|=4 Units
The Bearing of the Aeroplane is therefore given:
(i)From North Clockwise as: 90+45 =135 degrees
(ii)From a North South Line as
Since kites have two distinct pairs of consecutive, congruent sides their diagonals are perpendicular and one diagonal
bisects the other.
Since perpendicular lines intersect at 90° every triangle in a kite is a right triangle. Since it is given that angle DEF is 72° and we know triangles equal 180°
72+90=162
180-162 =18
so angle EFD is 18° and because angle EFD is a bisected part of angle EFG - 18x2=36
so angle EFG is 36°
