<span>To get the Greatest Common Factor of 129 and 86 we need to factor each value first and then we choose all the copies of factors and multiply.</span>
The passenger train is going 120MPH and the freight train is traveling 40MPH
Answer:
I'm not 100% correct but this is what I believe proportionality is where k=y/x and k is proportionality constant
$6.57: 3 pounds of orange
y dollar: x pounds of orange
so the proportion
$6.57 y
_____ = _____
3 x
6.57×
_____ = y
3
2.19x = y
so k = 2.19
The function is not linear because the slope is not constant. I am pretty sure that it is an exponential function, since the line approaches 0 but never touches it, and it grows exponentially. The exponential parent function is f(x)=b^x.
Hope this helped.
Answer:
See below
Step-by-step explanation:
Part A: The expression would be (4x+5)(3x+10), or, when expanded, 12x^2+55x+50 since the area of a rectangle is length*width
Part B: The degree is 2 because it's classified as a quadratic and trinomial expression
Part C: The closure property of polynomials is that polynomials will be closed under an operation if the operation produces another polynomial. For example, since we had to multiply two binomials in Part A, the exponents of x get combined to make x^2 (because x^1*x^1=x^(1+1)=x^2)
