Answer:
<h2><u><em>
x = -18</em></u></h2>
Step-by-step explanation:
X=20=-x+2 can you solve this?
assuming that the equation is:
20 = -x + 2
x = -20 + 2
x = -18

Answer:
the function is either increasing or decreasing
Step-by-step explanation:
For m ≠ 0, the function must be either increasing or decreasing. If the function is increasing, it will have its maximum value at the right end of the interval. If it is decreasing, its maximum value will be at the left end of the interval.
Answer:
Step-by-step explanation:
1). 10 = 
10(7 + x) = 1 + 7x
70 + 10x = 7x + 1
10x - 7x = 1 - 70
3x = -69
x = -23
2). 0.2 = 
0.2(12 + x) = 6 + 2x
2.4 + 0.2x = 6 + 2x
2.4 - 6 = 2x - 0.2x
1.8x = -3.6
x = -2
3). 0.8 = 
0.8(x + 0.5) = x
0.8x + 0.4 = x
x - 0.8x = 0.4
0.2x = 0.4
x = 2
4). 3.5 = 
3.5(0.5 - x) = 4 + 2x
1.75 - 3.5x = 4 + 2x
-3.5x - 2x = 4 - 1.75
-5.5x = 2.25
x = -
x = - 
Answer:
The number is 6
Step-by-step explanation:
Let x be the number
five times means multiply
5x
is 30 means equals 30
5x= 30
Divide each side by 5
5x/5 = 30/3
x = 6
