Answer:
Direct variation problems are solved using the equation y = kx. ... Step 3: Rewrite the equation from step 1 substituting in the value of k found in step 2. ... Example 3 – If c varies directly as the square root of d, and c = 6 when d = 256, find c ...
A equals 3 because 87 divided by 29 equals 3. You can check this by doing 29 times 3 which equals 87. Hope that Helped!
Answer:
-2
<em>BRAINLIEST, PLEASE!</em>
Step-by-step explanation:
5 - 3(2a + 1) = -4a + 10
5 - 6a - 3 = -4a + 10
2 - 6a = -4a + 10
-2a = 8
a = -4
-4 + 2 = -2
Answer:
if the question wants you to round. the answer is 4.
Step-by-step explanation:
f(x)=[x]-5
where x= 8.6
substitute 8.6 for x and you have 8.6-5= 3.6= 4
When you add 2 logs together, you get the log of the product.
When you subtract 2 logs, you get the log of the quotient.
Like this:
Ln(2) - Ln(3x+2) is the Ln(2/3x+2) .
So now you have Ln(2/3x+2) = 1
Raise 'e' to the power of
each side of the equation: (2/3x+2) = e¹
Multiply each side by (3x+2): 2 = (e) (3x+2)
Divide each side by 'e': 2/e = 3x + 2
Subtract 2 from each side: (2/e) - 2 = 3x
Divide each side by 3: x = [ (2/e) - 2 ] / 3
= approx. -0.421... (rounded)
I checked this by writing it into the original equation in place of 'x'.
That took my about 5 tries, but it finally checked OK.
Please. DON't use my answer unless you understand
where it came from.
