Answer:
Yes
Step-by-step explanation:
To see is (2, 6) is a system, we can plug it into the system to check if it gives us true statements:
6 = -2+8
6 = 6
6 = 5(2)-4
6 = 10-4
6 = 6
Both of the equations are true, therefore (2, 6) is a solution to this system.
The total is 94 units.
A square has four equal sides so...
(5x-1)+(4x+3)+(5x-1)+(4x+3)=94
Combine like terms
19x+4=94
Subtract 4 from both sides
94-4=90
18x=90
Divide by 18 on both sides
90/18=5
X=5
Plug 5 in for x on the length of PQ
4(5)+3
20+3=23
Length of PQ=23 units

Answer: -2</h3>
===============================================
Explanation:
We use the remainder theorem. This is the idea where if we divide P(x) over (x-k), then the remainder is P(k).
Comparing x+1 to x-k shows that k = -1
It might help to rewrite x+1 as x-(-1) to get it into the form x-k better.
Plug this k value into the function
f(x) = 2x^6 + 3x^5 - 1
f(-1) = 2(-1)^2 + 3(-1)^5 - 1
f(-1) = 2(1) + 3(-1) - 1
f(-1) = 2 - 3 - 1
f(-1) = -1 - 1
f(-1) =-2
The remainder is -2
We can confirm this through synthetic division or polynomial long division.
Answer:
$15.6
Step-by-step explanation:
one bag= $1.95
8 bags = 8×1.95=15.6
so answer is $15.6.
(2x + 10) + (6x + 1) = 180 - 79
