Answer:
A. n5+4 B. (4+n)5 C.(4+n)/5 D.(n*n)3 E. (n*3) 2
Step-by-step explanation:
I am not good at explaining but for E. the 2 will be squared but I am not sure how to type it out so Hope this can help ;)
Firstly mines 2x for 2 side
And combine 1 for 2 side
Result 6x^2+17x+5
So
(3x+1)(2x+5)=0
X=-1/3 or x=-5/2
This is NOT the graph of a function y=f(x). However, if you
solve the original equation for y in terms of x, you can break the graph into
two pieces, each of which is the graph of a function.
The real solution are : x= -4/sqroot7, y= 2/sqroot 7
x= 4/sqroot7, y= -2/sqroot
7
integer solution are: (-1,2) , (1,-2), (1,1)
Answer: 90
Step-by-step explanation:
set: {1, 2, 3, 4, 5, 6, 7} = 7 numbers | 3 even
no element may be used more than once in a number = distinct elements
and the number must be even = must finish with a even number.
This way, we should start with the last number, which we have 3 possibilities.
Since we have 7 numbers in total, we have 6 options for the first one and then 5 options for the second one.
So, we have 6.5.3 = 90
Answer:
so we substitute in K(x) into the equation K(x)=6x-12
which gets us: 18=6x-12
6x=30
x=5
