The first option,
both have to be negative, because they were originally both part of the one fraction, which was all negative.
Answer:
q = log4 / log0.53
q = -2.189
Step-by-step explanation:
(0.53)^q = 4
Taking log of both sides!
q log 0.53 = log 4
q = log 4 / log 0.53
q = 0.602 / -0.275
q = - 2.189
This can be checked to confirm correctness.
Substituting q = -2.189
(0.53)^ -2.189 = 1/ 0.249
= 4.01 Proved!
(Note that the "1" is because of the negative sign)
The answers of this equation are 39/37 and 6/5. To get the answers, the equation of the problem becomes 9(9-8x)=2x+3 and 9(8x-9)=2x+3. Then next step is to simplify first equation 1,
<span>81=74x+3.
After, equation 2 is simplified
</span><span>70x=3+81</span>

Answer:
No
Step-by-step explanation:
We know that the 3-4-5 and 9-12-15 right triangles are similar. If you add 6 units to the length of each side of both of these triangles, you obtain 9-10-11 and 15-18-21 triangles, which are not similar since 9/15 is not equal to 10/18.
