Answer:
C. 36
Step-by-step explanation:
3x12=36 :]
[x-1]=5x+10
We have two equations:
1) x-1=5x+10
x-1=5x+10
x-5x=10+1
-4x=11
x=-11/4
2) x-1=-(5x+10)
x-1=-(5x+10)
x-1=-5x-10
x+5x=-10+1
6x=-9
x=-9/6=-3/2
we have two possible solutions:
solution₁; x=-11/4
solution₂: x=-3/2
we check it out:
1) x=-11/4
[x-1]=5x+10
[-11/4 - 1]=5(-11/4)+10
[(-11-4)/4]=-55/4 + 10
[-15/4]=(-55+40) /4
15/4≠-15/4 This solution don´t work.
2) x=-3/2
[x-1]=5x+10
[-3/2 - 1]=5(-3/2)+10
[(-3-2)/2]=-15/2 + 10
[-5/2]=(-15+20)/2
5/2=5/2; this solution works.
Therefore:
Answer: x=-3/2.
Answer: Domain of the function represented in the graph is given by he inequality . 2 <_ x _< 10
Step-by-step explanation:
we know that
Observing the graph
The domain is the quantity of yellow paint in millimeters
The domain is the interval -----> [2,10]
All real numbers greater than or equal to 2 and less than or equal to 10
therefore 2 <_ x _< 10
my bad I couldn't put the line under the sign
Answer:
-2.65
Step-by-step explanation:
