the equation becomes y> 2x+5,
the graph would be C
Answer:
m∠ D = 110°.
Justification is below.
Step-by-step explanation:
Consider quadrilateral CDEF as a parallelogram,
Opposite sides of a parallelogram are parallel
∴ DE || CF
If two lines are parallel then the interior angles SUM is 180°
Angle C and Angle D are interior angles.
∴ m ∠C + m∠ D = 180°
Here
m ∠C = 70° {Given}
on substituting the above value we get
∴ 70 + m∠ D = 180°
∴ m∠ D = 180 - 70
∴ m∠ D = 110°
∴ m∠ D = 110° which is the required answer.
3x - 4y = 7 ; Solve for x
We're essentially just trying to get "x" onto it's own side.
So, in order to do this, we must get "y" onto the other side of our equal sign.
Add 4y to both sides.
3x = 4y + 7
Then, we divide 3 from both sides.
x = 4/3y + 7/3
15y + 1 = x ; Solve for y.
Instead of solving for x, we are now solving for y :)
So, in order to isolate y, we must subtract 1 from both sides.
15y = x - 1
Then, divide both sides by 15.
y = 1/15x - 1/15
