Answer:
-5/7
Step-by-step explanation:
Look at the graph. As we move from left to right from (-3, 2) to (4, -3), x increases by 7 and y decreases by 5. Thus, the slope is
m = rise/run = -5/7.
First we should figure out how much over the weight limit the passengers are. We can find this by 750-450 which is 300. The amount of weight that needs to get off the elevator is 300 kilograms. Then, we know that each passenger weighs 70 kilograms. We can represent this as 70p.The inequality is 70p \geq 300. Then we can solve by dividing both sides of the inequality by 70. We get p \geq 4.28... Since people only come in whole numbers, and it has to be greater than 4.28, the number of excess passengers is 5.

Answer:
.
Step-by-step explanation:
We want to find the polynomial that will result from expanding:
.
Recall that we can use the Pascal's triangle to obtain the coefficient as:
1 4 6 4 1
Also note how the negative sign is going to alternate.
The <em>power of x </em>will decrease from left to right while the <em>power of y</em> increases from left to right
The expansion then becomes:
.
8 x/3 apply the formula x power/root. Hope that helped!
