<u><em>Answer: =204 *The answer should be have a positive sign.*</em></u>
Step-by-step explanation:
This question it's about PEMDAS. This lesson it's about order of operation. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It must be go left to right.
do parenthesis first.
12(8+9)
9+8=17
multiply left to right.
12*17=204
=204
Hope this helps!
Thanks!
Have a great day!
To find the inverse,
First, you would have to switch the domain and range. In other words, swap x and y:
h(x) = 3/ -x-2
y = 3/ -x-2
x = 3/ -y-2
Then, when you have this, simply solve for y:
x = 3/-y-2
x (-y-2) = 3/-y-2 (-y-2)
x(-y-2) /x= 3 /x
-y-2 = 3/x
-y = 3/x + 2
y = -3/x -2
So the inverse would be
h⁻¹(x)= -3/x -2

Answer:
vertex: (-2, 4)
Step-by-step explanation:
Use your regression calculator to find the parameters of the quadratic model.
The vertex form equation is ...
y = -3(x +2)^2 +4
so the vertex is (-2, 4).

The standard form equation is the expansion of the above:
y = -3x^2 -12x -8
Answer:
Step-by-step explanation:
- Distance = 20 km
- Water consumed = 334 quarts
<u>Water consumption rate is:</u>
- 334 quarts / 20 km = 16.7 quarts/km
