Answer:
x= 1, x= 4, and x= -3
Step-by-step explanation:
Use the possible combinations of factors of the constant term of the polynomial to find a first root. Try 1, -1, 2, -2, 3, -3, etc.
Notice in particular that x = 1 is a root (makes f(1) = 0):
So we know that x=1 is a root, and therefore, the binomial (x-1) must divide the original polynomial exactly.
As we perform the division, we find that the remainder of it is zero (perfect division) and the quotient is: 
This is now a quadratic expression for which we can find its factor form:
From the factors we just found, we conclude that x intercepts (zeroes) of the original polynomial are those x-values for which each of the factors: (x-1), (x-4) and (x+3) give zero. That is, the values x= 1, x= 4, and x= -3. (these are the roots of the polynomial.
Mark these values on the number line as requested.
Answer:
15, d
Step-by-step explanation:
The absolute value of |-11| + |4| is 11+4 which is 15
You would multiply 4 on both sides
5x=2
then you would divide 5 on both sides
x=2/5

Adrian can run 3/4 mile in 1 morning.
----------------------------------------------------------------
Find how long he needs to run 1 mile
----------------------------------------------------------------
3/4 miles = 1 morning
[ Divide by 3/4 on both side ]
3/4 ÷ 3/4 miles = 1 ÷ 3/4
1 miles = 4/3 morning
----------------------------------------------------------------
Find how long he needs to take to run 3 miles
----------------------------------------------------------------
1 miles = 4/3 morning
[ multiply by 3 through ]
3 miles = 4/3 x 3
3 miles = 4 mornings
----------------------------------------------------------------
Answer : 4 mornings
----------------------------------------------------------------
To set the equation,we can first find how much price would be raised within a year:
=500×(1+7%)
=500×1.07
As the years go by the increase would accumulate,and the equation would be:
Hope it helps!
