Answer:
the answer is 9/ 15
Step-by-step explanation:
Sin y = p / h
= 9/ 15 (from y reference )
cos x =b/h = 9 / 15
as from x reference b= 9
I hope this will be helpful to you
if yes give 5 star
Answer:
B
Step-by-step explanation:
In order for something to have infinite solutions, both sides need to be equal to each other.
Example:
3x + 7y = 7y + 3x
That has infinite solutions
3x + 7y = 7x + 3y
That is not equal to each other because the variables are different.
Hope I helped :)
Answer: 6x^2 - 12x - 21
Explanation:
h(x) = 2x^2 - 4x - 7
h(3x) = 3(2x^2 - 4x - 7)
h(3x) = 6x^2 - 12x - 21
X^3-3x^2+x+5=(x+1)(x^2-4x+5)
(x+1)(x^2-4x+5)=0
x+1=0→x+1-1=0-1→x=-1
x^2-4x+5 different to zero
The root of the equation is x=-1
