d) 12
Answers
I hope this helps:D
Answer:
Answer is a) 9
Step-by-step explanation:
9 x 4 = 36
36 + 5 =41
Hope this help (｡･ω･｡)
Edit:
or you can use this method
41 - 5 = 36
36 divides by 4, then you will get 9

Answer:
x = 4 + √73
Step-by-step explanation:
The given equation is ( x-12 ) ( x + 4 ) = 9
We will solve the equation first.
( x - 12 ) ( x + 4 ) = 9
x( x+4 ) - 12 ( x + 4 ) = 9 [ Distributive property ]
x² + 4x - 12x - 48 = 9
x² - 8x - 48 = 9
x² - 8x - 48 - 9 = 0
x² - 8x - 57 = 0
[ x² - 2 (4x) + 16 ] - 57 - 16 = 0
(x - 4)² - 73 = 0
(x - 4)² = 73
( x-4 )² = √73
x = 4 + √73
x = 4 + √73 is the answer.
You can multiply (x-12) and (x+4)
x * x = x^2
x * 4 = 4x
-12 * x = -12x
-12 * 4 = -48
Now we have
x^2 - 8x - 48 = 9
Subtract 9 from both sides
x^2 - 8x -57 = 0
Use the quadratic formula
This give use the answer of
x = 4 +

Answer:
2236.5
Step-by-step explanation:
The regression equation for predicting hiker's elevation is
y=9.06x+651.
Here x is the number of minutes.
We wish to estimate hiker's elevation after 175 minutes. For this purpose we put x=175 in the predicted regression equation.
y=9.06(175)+651
y=1585.5+651
y=2236.5
Thus, the hiker's elevation after 175 minutes is 2236.5 feet.

Answer:
the sign of the product would be a negative or "-"
Step-by-step explanation:
Final answer:
The sign of the product of -2/9 × 1/7 is negative because one of the numbers being multiplied is negative and the other is positive.
Explanation:
In mathematics, the sign of a product is determined by the sign of the numbers that are being multiplied. When multiplying two numbers, if both numbers are positive or both numbers are negative, the product will be a positive number. If one number is positive and one is negative, the product will be a negative number.
In our case, we are multiplying -2/9 and 1/7. The number -2/9 is negative and the number 1/7 is positive. Since one number is positive and the other one is negative, the sign of the product -2/9×1/7 will be negative. Thus, we enter '-' for negative.
