Answer:
y= -4x+4
Step-by-step explanation:
y=mx+b
where x=-1, y=8, and m=-4
8=(-4)(-1)+b
8=4+b
4=b
Thus, y= -4x+4
X=-12,-5/2 you could find the answer by solving for x
Answer:
Step-by-step explanation:
<u>As per equation, the initial amount is:</u>
- A(0) = 458*(1/2)^(0/30) = 458*1 = 458 g
<u>Sample amount left after 50 years:</u>
- A(50) = 458*(1/2)^(50/30) = 144 g (rounded)
Answer: 3x^3 -8*x^2 + 8*x + 3
Step-by-step explanation:
The standard form for a plolynomial is:
a*x^n + b*x^(n-1) + c*x^(n - 2) ........
We have:
(x-1)(3x^2-5x-3)
this is equal to:
3*x^3 - 5*x^2 + 3*x - 3*x^2 +5*x + 3
where the thing that i did is distribute the multiplication
this is equal to:
3x^3 -8*x^2 + 8*x + 3
6^8
You multiply 2 and 4 so 2x4=8
This is one of the exponent rules
