Answer:
1. no solutions
2. one solution
Step-by-step explanation:
1. -4(5-3x)=12x+20
-20+12x=12x+20
-40+12x=12x
-40=0?????
So no solutions.
2. 3x+7(x+1)=2(6x+5)+2
3x+7x+7=12x+10+2
10x+7=12x+12
-2x+7=12
-2x=5
x=-5/2
So one solution.
<u>Step-by-step explanation:</u>
From the following figure, We can see that we have a graph with different lines where some points are included and some are not . Let's find out the listed values using graph:
<u>F(-10):</u>
From the graph F(-10) = -6 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
<u>F(-4):</u>
From the graph F(-4) = 0 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
<u>F(-2):</u>
From the graph F(-2) = 2 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
<u>F(0):</u>
From the graph F(0) = -1 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
<u>F(3):</u>
From the graph F(3) = -7 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .

Answer:
A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.
