4x - 4x - 5 = -5
4x - 4x = -5 + 5
0 = 0
this equation has infinite solutions
Answer:
Step-by-step explanation:
Positive integers are of the form 2n
The first term is 2 and the 130th term is 2(130)=260
The sum of this arithmetic sequence is the average of first and last terms times the number of terms
(2+260)(130/2)
17030
Answer:
4y - x = 20
Step-by-step explanation:
y-y1 = m (x-x1)
y - 6 = 1/4 (x - 4)
4y - 24 = x - 4
4y - x = 20
Answer:
Cubic trinomial
Step-by-step explanation:
The degree of a term is the sum of the exponents of its variables
- Quadratic: a polynomial of degree two
- Cubic: a polynomial of degree three
Therefore, -5x³ - 4x + 1 is a cubic (since the sum of the exponents is 3)
- monomial: a polynomial with exactly one term
- binomial: a polynomial with exactly two terms
- trinomial: a polynomial with exactly three terms
Therefore, -5x³ - 4x + 1 is a trinomial (as it has exactly 3 terms)
Answer: -3.
Step-by-step explanation:
We are given that :
(1)
It means that f(x) and g(x) are proportional.
[Equation of direct variation: y=kx , where k= proportionality constant.]
From the given graph ,
At x= -3 , f(x)=1 and g(x) =-3
Put value of x=-3 in (1) , we get
[∵ f(x)=1 and g(x) =-3]
i.e. The value of k = -3
Hence, the correct answer is -3.
