If this is the case, then you know by the polynomial remainder theorem that
![x-a](https://tex.z-dn.net/?f=x-a)
is a factor of
![p(x)](https://tex.z-dn.net/?f=p%28x%29)
, so there is some polynomial
![q(x)](https://tex.z-dn.net/?f=q%28x%29)
such that
Answer:
6x, 2x + 4, 5y + 11
Step-by-step explanation:
x + x + x + 2x + x = 6x
(x + 2) + (x + 2) = 2x + 4
y + y + y + y + 10 + y + 1 = 5y + 11
Step-by-step explanation:
the cost of 8 books at $4 each
=》8 × 4 = $ 32
the cost of x books at $4 each
=》x × 4 = $ 4x
the cost of 5 books at $x each
=》5 × x = $ 5x
Answer:
<h2>x=5/7</h2><h2>y=12/7</h2>
Step-by-step explanation:
5x+2y=7
5x+2(x+1)=7
5x+2x+2=7
7x=5
x=5/7 or ~0.71
y=5/7+1
y=12/7 or ~1.71
<u>Check your solutions:</u>
1.71=0.71+1
1.71=1.71 ✅
5(0.71)+2(1.71)=7
3.55+3.42=6.97 ✅
we rounded down so this answer is fine
