HURRY PLEASE Which term is like -4k? A. -4 B. -2 C. 12k

erik [133]

Answer:

$-5, 18, \sqrt{13}$

Step-by-step explanation:

We can solve the first equation, f of -3. The value of the function f is $\frac{1+x^2}{x+1}$ , and plugging in -3 gets us $\frac{1+9}{1-3}$ , this results in 10 divided by negative 2, which is negative 5.

Now, we must solve g of negative one third. The function g is defined as $|9x-15|$ . Plugging in negative one third into the question gets us $|9(-\frac{1}{3})-15|$

9 times negative one third is -3, and -3 minus 15 is -18. The absolute value of -18 is 18.

Now, we must solve h of negative 2, and h is defined as $\sqrt{-3-8x}$ . Plugging in negative 2, we have $\sqrt{-3-8(-2)}$ . Negative 8 times negative 2 is positive 16, and 16 minus 3 is 13. The answer is the square root of 13

1) Compare the function with the parent function. without graphing, what are the vertex, axis of symmetry and transformations of

Mama L [17]

I guess the parent function to be: y = |8x|.

To translate a function m units to the right, you must substitute x by x-m. You had y = |8x|. You substitute x by x-1/4, to get:

y = |8(x-1/4)| = |8x-2|

So, the function was translated to the right 1/4 unit.

To translate a function vertically n units, you add (translate up) or subtract (translate down) m to the function. You had y = |8x-2|. You subtract 7 to get:

y = |8x-2|-7

Hence, the parent function was translated 7 units down.

The vertex is the point where the content of the absolute value changes its sign, that is, the where it equals zero:

8x-2 = 0 <=> x=1/4

The x coordinate of the vertex is therefore x=1/4. To calculate the y coordinate of the vertex, you must substitute the x coordinate in the equation of the function, to get:

x=1/4 => y = |8(1/4)-2| - 7 = -7

The vertex is, therefore, (1/4,-7).

Finally, the axis of symmetry is a vertical line through the vertex: x=1/4 (the equation of a vertical line is of the form x=a).

The correct answer is D).

Comparing freezers

zvonat [6]

Answer:

Freezer B has 8 more cubic feet than Freezer A.

Step-by-step explanation:

Volume of Freezer A = 8 * 4 * 2 = 64 ft^3.

Volume of Freezer B = 6 * 4 * 3 = 72 ft^3.

72 - 64 = 8 ft^3.
