5c² - 17c - 14
It cannot be factored.
Plug in 1
and −1
to get two values of r(x)
which is linear. From there you can get what a,b
are in ax+b.
Since
f(x)=g(x)(x+1)(x−1)+r(x)
we have
f(1)=g(1)(1+1)(1−1)+r(1)=r(1)=−10
f(−1)=g(1)(−1+1)(−1−1)+r(−1)=r(−1)=16
We know the remainder is of degree 1
, so
r(x)=ax+b
and now we know,
r(1)=ax+b=a+b=−10
r(−1)=ax+b=−a+b=16
so, solve
a+b=−10
−a+b=16
which yields, a=−13
b=3
, so
r(x)=−13x+3
Answer:
3+3
5+1
6*1
Step-by-step explanation:
So, first you use what you already know. Put 60 over 100, since 60 is your percentage; put 192 as your denominator, with a "?" as the numerator to represent the missing/unknown part of the fraction. Next, cross multiply, or multiply 60x192 (which is 11520), then divide the product by 100. Your final answer is 115.2. Hope you found this helpful!
1. -9(T-2)=4(T-5)
Distribute
-9t+18=4t-5
Sub 4 because t is a like term and it is positive so sign changes because it is in opposite sides.
-14t+18=-5
Sub 18 to like term which is -5
-14t=-23
Divide
T= -14/-23 or -0.4375
2. 2(4x+2)=4x
Distribute
8x+4= 4x
Sub 8x
4=-4x
Divide -4x
X=-1
3. 26-4s=9s
Sub -4s
26=5s
Divide 5s
5/26 or 0.03846154
