Answer:
The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base. In general, y = logb x is read, “y equals log to the base b of x,” or more simply, “y equals log base b of x.” As with exponential functions, b > 0 and b ≠ 1
Answer:
x = 4
Step-by-step explanation:
<u>All triangles add up to 180 degrees</u>
76 + 17x + 9x = 180
76 + 17x + 9x - 76 = 180 - 76
26x / 26 = 104 / 26
x = 4
Answer: x = 4
Answer:
3:6:4
Step-by-step explanation:
We are given that
Number of apples in the basket=12
Number of pears in the basket=24
Number of oranges in the basket=16
We have to find the ratio of apples, pears and oranges in the basket.



HCF (12,24,16)=4
Now, divide each number by HCF
Then, we get
3:6:4
Therefore, the ratio of apples, pears and oranges in the basket.
3:6:4
Answer:
A
Step-by-step explanation:
(x, y) -----> (x + 4, y - 1)
Adding 4 to the x means you move right 4. Subtracting 1 from the y means you move down one.
The next transformation (-(x + 4), y - 1)
If you look at the x coordinate and the transformation that is being applied
(-(x+4) that negative means you are taking the opposite of the x coordinate.
When you take the opposite of the x coordinate, it means you reflect it over the y axis.
<u>Given</u><u> </u><u>:</u><u>-</u>
- The roots of the function are 5 and -3 .
<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>
<u>Answer</u><u> </u><u>:</u><u>-</u>
The roots of the function are 5 and -3 . In general we can write the Quadratic function with roots π and ∆ as ,
f(x) = ( x - π )(x-∆)
So on using this we have ,
f(x) = ( x -5)( x -(-3))
f(x) = (x-5)(x+3)
f(x) = x(x-5)+3(x-5)
f(x) = x² -5x +3x -15
f(x) = x² -2x -15
<u>Hence </u><u>the</u><u> required</u><u> </u><u>answer</u><u> </u><u>is </u><u>x²</u><u> </u><u>-2x </u><u>-</u><u>1</u><u>5</u><u>.</u>
