Hello,
Assume Ax+By+Cz+D=0 the plane 's equation.
p=(0,0,0)==>A*0+B*0+C*0+D=0==>D=0
q=(0,1,0)==>A*0+B*1+C*0+0=0==>B=0
r=(1,2,3)==>A*1+0*2+C*3+0=0==>A=-3C
Let C=1==>A=-3
An equation of the plane is -3x+z=0
Answer:
465.5
Step-by-step explanation:
If you plug in the numbers into the formula.
base 1= 15
base 2= 34
height= 19
The first one because the slope is 2/1 and y-intercept is -4
The equation should be 7x^2 -x-9=0
Answer:
