Answer:

Step-by-step explanation:
The given inequality is

To solve this inequality, we just have to isolate 


Therefore, the solutions for this inequality is
.
If we graph this inequality, the solution would be like the image attached.
400gr is 0.4 kg
so 6*0.4=2.4 dollars
Answer: 400grams cost 2.4 dollars
Answer:
a) f(0)=2
b)f(2)=-4
c)f(0)+f(2)=-2
d)f(3)*f(-2)=-56
e)f(0):f(2)=-1/2
Step-by-step explanation:
f(x) =-3x+2
a) f(0)=-3*0+2=2
b) f(2)=-3*2+2=-6+2=-4
c) f(0)+f(2)=2-4=-2
d)f(3)*f(-2)=-7*8=-56
f(3)=-3*3+2=-9+2=-7
f(-2)=-3*(-2)+2=6+2=8
e)f(0):f(2)=2/(-4)=-1/2

1) As we can see this is a Linear Equation written in the Slope-intercept form:

Note that "m" stands for the slope of the line, i.e. the measure of how steep a line is.
In the given equation, we can state that the slope is always accompanying the "x" therefore, the slope is m= 7
2) In addition to this, the y-intercept also called the Linear Coefficient is given by the letter"b" and represents the y-coordinate that the graph intercepts. Thus the y-intercept is -6
So we can state the following as the answers:

And that is the answer
