The answer is D, happy graphing.
4+x=7
Move +4 to the other sign. Sign changes from +4 to -4.
4-4+x=7-4
x=3
Answer: x=3
Equation of the line is y=mx+b
the line passing through point (1;-2) so x=1 y=-2
m=-0.5 so put all these values in equetion and found value of b
-2=-0.5*1+b
-2=-0.5+b
b=-1.5
so equation of the line is y=-0.5x-1.5
Answer:
equation of the line is y=-0.5x-1.5
So simple interest, you don't compound anything, you will always add 3% from $9500 and it will not change. The equation will look like this:
9500*[1+(0.03*8)]
giving us 9500*1.24 = $11,780
0.7=7/10
0.8=8/10
0.75=3/4 this is between 0.7 and 0.8
