Answer:
Step-by-step explanation:
It looks like your interactive graphing tool needs you to plot some points on each of the lines. For these lines, it is convenient to use the x- and y-intercepts. Each intercept can be found by dividing the constant by the coefficient of the variable.
<u>-7x -2y = 14</u>
The x-intercept is 14/-7 = -2. Plot (-2, 0) on the x-axis.
The y-intercept is 14/-2 = -7. Plot (0, -7) on the y-axis.
<u>6x +6y = 18</u>
The x-intercept is 18/6 = 3. Plot (3, 0) on the x-axis.
The y-intercept is 18/6 = 3. Plot (0, 3) on the y-axis.

The point of intersection of the two lines is the solution: (x, y) = (-4, 7).
The best information we can use is the ratio of defectuosity, 2/150
Applying it to the size of the batch
N=3000*2/150 = 40
Answer: out of the batch of 3000 products, likely 40 products are defective, if the products are drawn from the same production run.
Answer:
z = 4
y = 6
a = 36
r = 21
m = 15
s = 2
c = 6
v = 45
Step-by-step explanation:
Notice that you can re-write it as:
x^2+y^2+(z-1)^2 = 1
Now you should know (shifted ... sphere in the z axis by 1 unit, right)
