Answer:
Option B. 7.6
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
where
k is the constant of proportionality
The slope of the linear equation is the same that the constant of proportionality
In this problem we have

so
the slope is 
therefore
The constant of proportionality k is 
Given a polynomial functin
ax^2+bx+c, the highest degree is 2
given another polynomial say ax^3+bx^2+cx+d, the degree of the polynomial is 3.
From the above we can conclude that the degree of a polynomial is its highest power.
From the function given:
5+7x^9+12x-5x^7+3x^2
The highest power is 9, thus it is a polynomial of degree 9.
The coefficient of the term of degree 9 is 7.
The answer is 7.
4 consecutive odd numbers....x, x + 2, x + 4, x + 6
2(x + x + 2) = 3(x + 4 + x + 6) - 40
2(2x + 2) = 3(2x + 10) - 40
4x + 4 = 6x + 30 - 40
4x + 4 = 6x - 10
4x - 6x = -10 - 4
-2x = - 14
x = -14/-2
x = 7
x + 2 = 7 + 2 = 9
x + 4 = 7 + 4 = 11
x + 6 = 7 + 6 = 13
ur numbers are : 7,9,11,13 <==
Answer:
1:4
Step-by-step explanation:
there are 5 questions. there is one correct answer so the rest must be wrong. so the ratio of correct to wrong is 1:4.
