2x+9=6x+7. 2x+2=6x. 2=4x. X=1/2 a year
Therefore, slope of line DC = slope of line AC = -0.4.
Answer:
4
Step-by-step explanation:
in this case it doesn't matter, but it is confusing, if you type it in a web calculator, it will understand x**x=x^x (exponent)
but if you mean multiplication it's only one
but in our case
2**2=2^2=4
and also
2*2=4
so the answer is 4 in both cases
