First:
2x + 2z = 4
2(x+z)=4
x+z=4/2
x=2-z
-x - y - z= -8
-(2-z)-y-z= -8 replace x
-2+z-y-z= -8 (cancel z)
-2-y= -8
6 = y
Then:
-4x + 4y + 5z = 7 replace x and y
-4(2-z)+4*6 + 5z = 7
-8 + 4z + 24 + 5z = 7
16 + 9z = 7
9z = 7 - 16
9z = -9
z = -9/9
z= -1
Finally
x= 2-z replace z
x = 2- (-1)
x = 3
Answer:
d. 2
Step-by-step explanation:
The average rate of change is found from ...
... (f(x2) -f(x1))/(x2 -x1) = (5 - 3)/(2 -1) = 2/1 = 2
Answer:
220
Step-by-step explanation:
V= whl = 5 · 11 · 4 = 220
Answer: 25 inches
Step-by-step explanation:
Let's imagine that this line is the leg A______________B________C
x 11
|___________36____________|
From A to C = 36 inches
From B to C = 11 inches
To find A to B all we have to do is subtract the knee to ankle length (11) from total leg length (36), which 36 - 11 = 25 inches.
The slope of the original line is 1 so the perpendicular slop is -1
