Answer:
4π
Step-by-step explanation:
4x² + 9y² = 36
Divide all through by 9
4/9x² + ²y² = 44


X= 30/r is the answer because if you divide both sides by r you are left with x=30/r because you cant divide 30 by r
Yes it does determine a plane
Answer:
- 5
Step-by-step explanation:
The equation of a line in slope - intercept form is
y = mx + c ( m is the slope (gradient) and c the t- intercept )
y = 3x - 8 ← is in slope- intercept form
with gradient m = 3 and y- intercept c = - 8 , thus
m + c = 3 + (- 8) = 3 - 8 = - 5
