area is 50.27
Answer:
k ≤ 10 or k ≤ -6
Step-by-step explanation:
| -2 + k | ≤ 8
-2 + k ≤ 8
k ≤ 10
-2 + k ≤ -8
k ≤ -6
Desmos graphing calculator will draw this graph for you.
draw 2 curves
y = x^4 + x^3
and
y = 4x^2 + 4x
The roots are the points where the 2 curves intersect.
You can see by simple substitution that one root is zero.
x^4 + x^3 - 4x^2 - 4x = 0
f(2) = 16 + 8 - 4(4) - 4(2) = 0 so 2 is another root
f(-2) = 16 - 8 - 16 + 8 = 0 so -2 is another root
f(-1) = 1 - 1 - 4 + 4 = 0 so -1 is the other root
The answer is A
Answer:
L+C=14
10C+11L=145
Step-by-step explanation:
Let C represent Car Washing
Let L represent Landscaping
If Mila worked a total of 14 hours; then
L+C=14
If Mila earned a total of $145, then
10C+11L=145
Hence;
The system of equation are:
L+C=14
10C+11L=145
