The answer is 4. All of the above
We know that the load is 8713 lbs.
The total weight (truck + load) is 17200 lb.
Then, we can calculate the weight of the empty truck as:
![\begin{gathered} L=8713 \\ W=L+T=17200 \\ \Rightarrow T=W-L \\ T=17200-L=17200-8713=8487 \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20L%3D8713%20%5C%5C%20W%3DL%2BT%3D17200%20%5C%5C%20%5CRightarrow%20T%3DW-L%20%5C%5C%20T%3D17200-L%3D17200-8713%3D8487%20%5C%5C%20%20%5Cend%7Bgathered%7D)
Answer: the empty truck's weight is 8487 lb.
T: empty truck's weight
W: total weight (loaded truck's weight)
L: Load
The equation is:
T = W - L
Answer:
D. (y +4)² = -4(x -2)
Step-by-step explanation:
The directrix is a vertical line, and the focus is to the left of it. The parabola will open to the left.
The vertex is halfway between the focus and directrix, so is located on the same horizontal line as the focus, at ...
x = (1 +3)/2 = 2
The focus to vertex distance is the difference in x-coordinates: 1 -2 = -1. This is the value of p in the form ...
(y -k)² = 4p(x -h) . . . . . . . parabola with vertex (h, k)
The equation is ...
(y +4)² = -4(x -2)
_____
<em>Additional comment</em>
Once you determine that the directrix is a vertical line, you know the equation will have a y² term. The only answer choice that has that is D.
Answer: 3
Step-by-step explanation:
Simplify the expression.
(-4+3) - (2-6)
-4+3 = -1
2-6 = -4
Subtract: -1 - (-4) = 3
Debbie goes to a diner famous for its express lunch menu. The menu has 5 appetizers, 3 soups, 7 entrees, 6 vegetables, and 4 desserts. How many different meals consisting of either an appetizr or a soup, one entree, one vegetable, and one dessert can Debbie order?
