Hi dear,
use this formula:
y - y1= m(x-x1)
Y1 = -3
X1 = 0
m = 4
y-(-3)=4(x-0)
y+3=4x
y=4x-3
To find the midpoint, you are basically finding the average (or mean) between the two coordinates, J and N.
Start by finding the average between the x coordinates of J and N: 10 and -4. Add them together then divide the total by 2.
10 + (-4) = 6; 6/2 = 3
The average of the x coordinates is 3. Now find the average of the y coordinates. Start by adding -2 and 6 together then dividing the total by 2.
-2 + 6 = 4; 4/2 = 2
3 is the average of the x coordinates and 2 is the average of the y coordinates, so that means the midpoint of J and N must be (3, 2).
The conjecture is False. A,B,C are in one plane, D is above the plane, therefore the points are not coplanar.
The statement doesn't specify where the points are.
Step-by-step explanation:
x² + y² + z² = 3(2x - y) - 1
x² + y² + z² = 6x - 3y - 1
x² - 6x + y² + 3y + z² = -1
(x - 3)² + (y + 1.5)² + z² = -12.25
(x - 3)² + (y + 1.5)² + z² = -(3.5)²
Since it follows the general equation form, it is a sphere.
Answer:
$200
Step-by-step explanation:
What you have to do is round the earnings so $37.38=$40, $20.46=$20, $49.84=$50, $87.22= $90. Then add them together 40+20+50+90=200
