Answer:p(-7)=0
Step-by-step explanation:
This is the answer Plato gave me
Answer:
y = 35x + 100
Step-by-step explanation:
she started with $100, which is the y-intercept. After 7 months, she has 245 more. 245/7 = 35 per month. this is your slope.
Especially if we're to present the answers to 2 decimal places, we'd gues that the roots of this polynomial are not "nice."
My suggestion is that we use the quadratic formula to find the roots, and then write the associated factors.
In 3x^2 +x-5=0, a=3, b=1 and c= -5. Thus, the roots are
-1 plus or minus √(1^2 - 4(3)(-5) )
x = --------------------------------------------------
2(3)
or:
-1 plus or minus √61 -1 plus or minus 7.81
x = ----------------------------------- = ---------------------------------
6 6
Then one root is 6.81/6, or approx. 1.14, and the other is
-8.81/6, or approx. -1.47.
The solution set is then {-1.47, 1.14}.
You would change that to a decimal first and it will be .125 then put that number over 1000 and the answer is 1/8
