Answer:
![-13a+22](https://tex.z-dn.net/?f=-13a%2B22)
Step-by-step explanation:
we have
![2(a+5)-3(5a-4)](https://tex.z-dn.net/?f=2%28a%2B5%29-3%285a-4%29)
step 1
Apply the distributive property both terms
![2a+2(5)-3(5a)+3(4)](https://tex.z-dn.net/?f=2a%2B2%285%29-3%285a%29%2B3%284%29)
![2a+10-15a+12](https://tex.z-dn.net/?f=2a%2B10-15a%2B12)
step 2
Combine like terms
![(2a-15a)+(10+12)](https://tex.z-dn.net/?f=%282a-15a%29%2B%2810%2B12%29)
![(-13a)+(22)](https://tex.z-dn.net/?f=%28-13a%29%2B%2822%29)
![-13a+22](https://tex.z-dn.net/?f=-13a%2B22)
Answer:
3575880
Step-by-step explanation:
We need to use Permutation method,
![nPr= \frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=nPr%3D%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
Where n is the sample of size and r the combination considered, so
![n=45\\r=4\\45P4= \frac{45!}{(45-4)!}\\45P4 = 3575880](https://tex.z-dn.net/?f=n%3D45%5C%5Cr%3D4%5C%5C45P4%3D%20%5Cfrac%7B45%21%7D%7B%2845-4%29%21%7D%5C%5C45P4%20%3D%203575880)
There is 3575880 possibilities to make leadership structures in that committee
Both are equal because the distance from AB is equal to RS.
The solution is x=3/4
How can we solve given equation?
First, we will solve like terms. Then shift constant to other side and keep x on the same side to get the value of x.
We can solve given equation as shown below:
5/2-3x-5+4x=-7/4
(5-10)/2+x=-7/4
-5/2+x=-7/4
x=5/2-7/4
x= (10-7)/4
x=3/4
Hence, the solution is x=3/4.

The answer is a. <span>It represents a linear function because there is a constant rate of change. This can be done the opposite way, but lets use minutes as x and hours as y. Every time y increases by 1, x increases by 60. This means there is a constant rate of change of 1 (rise) over 60 (run). A linear equation must have a constant rate of change.</span>
