Answer:
y = -2x + 11
Step-by-step explanation:
Degree: 5; leading coefficient: 10
Option D is correct.
Step-by-step explanation:
We need to identify if
is a polynomial function, then state its degree and leading coefficient or not.
A polynomial is an algebraic expression containing two or more terms that have same variables but may have different exponents combined through mathematical symbol(+,-,*or/)
So,
is a polynomial function
The degree of polynomial is the highest degree obtained by sum of all exponents of individual terms in the polynomial.
So,
has highest degree 5
Degree = 5
The leading coefficient is the coefficient of first term of the polynomial.
So,
has leading coefficient = 10
So, Leading coefficient = 10
So, Degree: 5; leading coefficient: 10
Option D is correct.

(3x^2+9x-6) - (2x^3-4x^2+6x-4)
Short Answer
2x^3+7x^2+3x-2
Step by Step
1.)2x^3 doesn’t subtract from anything because there are no other trinomials
2.)3x^2 - (-)4x^2 = 7x^2 because a double negative cancels out and you end up adding them
3.)9x-6x=3x
4.)-6 - (-)4 = -2 because double negatives cancel out into addition
4 unit rate is 124. 5 unit rate is 16 6 unit rate is 60
People in building ---- x (men, women and children)
children --- y
men + women + children = x
(3/7)x + (5/8)(4/7)x + y = x
3x/7 + 5x/14 + y = x
times 14
6x + 5x + 14y = 14x
14y = 3x
y + 220 =x
sub into the other one
14y = 3(y+220)
11y = 660
y = 60
then 14(60) = 3x ---> x = 280
So we have 280 people in the building.
check: 3/7 of 280 are men = 120
leaving 160 women and children
5/8 of these ot 100 are women
so we have 120 men, 100 women and 60 children!
hope this is right! have a great. day
