Answer:
the point form is (1,2) and the equation form is x=1 and y=2
Step-by-step explanation:
Since the logarithms have the same base, we can simply divide (x^2 + 6x + 8) by (x+ 2) and just retain the sme base. So, the answer will be Log4(x+4)
Solve for x over the real numbers:
-5 + 1/5 + 3/x = 9/20
-5 + 1/5 + 3/x = 3/x - 24/5:
3/x - 24/5 = 9/20
Bring 3/x - 24/5 together using the common denominator 5 x:
-(3 (8 x - 5))/(5 x) = 9/20
Cross multiply:
-60 (8 x - 5) = 45 x
Expand out terms of the left hand side:
300 - 480 x = 45 x
Subtract 45 x + 300 from both sides:
-525 x = -300
Divide both sides by -525:
Answer: x = 4/7
X= 18 and y= 15
point form: (18,15)
Answer:
To solve this problem, we can use Pythagorean theorem, it tells us that the square of the hypotenuse is equal to the sum of the square of the other two sides.
When we look at these side lengths, we can see that only the second answer is suitable because from the lengths, we can predict that 13 is the length of the hypotenuse, 5 is the length of the shorter leg and 12 is the length of the other leg, and when you actually calculate it, the result is correct as well:
5² + 12² = 25 + 144 = 169
13² = 169
So the answer is B
