First answer is correct because angles DAB and EAD equal 180 degrees (supplementary)
3x+15−7x=−7
Simplify:
3x+15−7x=−7
3x+15+−7x=−7
(3x+−7x)+(15)=−7(Combine Like Terms)
−4x+15=−7
Subtract 15 from both sides.
−4x+15−15=−7−15
−4x=−22
Divide both sides by -4.
−4x/−4=−22/−4
x=11/2

Answer:
The question is incomplete, the complete question is "Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. See Example 9. 
.
Step-by-step explanation:
From the general properties or laws of logarithm, we have the
where both log are now express in the natural logarithm base.
i.e 
hence we can express our 
.
the value of ln7 is 1.9459 and ln4 is 1.3863
Hence 
.
Answer:
Step-by-step explanation:
A parameter describes a population, and a statistic describes a sample.
The first one is a statistic. A sample was surveyed.
The second one is a parameter. It describes the entire soccer team.
