Equation 1: 3x + 2y + 4z = 12
Equation 2: x + y + 2z = 6
Substituting x = 0, y = 4 and z = 1 into equation 1 and equation 2 and if the answer equals to 12 and 6 then the two lines intersect at the given point
Equation 1 ⇒ 3(0) + 2(4) + 4(1) = 0 + 8 + 4 =12
Equation 2 ⇒ 0 + 4 + 2(1) = 4 + 2 = 6
We have the answer of 12 and 6, hence the two lines intersect at the given point
-------------------------------------------------------------------------------------------------------------
Equation 1: -2x - 4y + z = 8
Equation 2: 4x + 2y = -5
Given point: x = -2, y = 0, and z = 3
Equation 1 ⇒ -2(-2) - 4(0) + 3 = 4 - 0 +3 = 7
Equation 2 ⇒ 4(-2) + 2(0) = -8 + 0 = -8
The answers are not 8 and -5 hence the lines don't intersect at given point
Answer:
If 21 is the height, and 4 is the radius, then the volume is approx. 1055.58
Step-by-step explanation:
Hi again! I'm assuming that the straight line, which I believe is for y = -2 doesn't belong because everything else has two lines, I mean like it reflects off a certain point on the x or y axis but b) [as I like to call it] doesn't reflect on another axis.
Smaller x = -2/5
Larger x = 5
