Answer:
The given equation is NOT linear.
Step-by-step explanation:
5x^4+5y = 9
The given equation is NOT linear.
Reason:
A linear equation is defined as the equation for the straight line, where the degree of variables involved is always equal to 1.
But in the given equation :
Degree if x = 4
and degree of y = 1
As degree of x≠ 1 so, the given equation is not linear,
Answer:
x = 7
Step-by-step explanation:
Let x = the number. Then
"Triple a number" means 3x
"is the same as" means =
"double the number increased by 5" means 2x + 7
∴ 3x = 2x + 7
Subtract 2x from each side
x = 7
The answer is x = 7.
Check:
3 × 7 = 2 × 7 + 7
21 = 14 + 7
21 = 21
OK.
Answer:
y = -6x + 3
Step-by-step explanation:
y = -3(2x) -3(-1) = -6x + 3(1) = -6x + 3
Answer:
C. Tan
Step-by-step explanation:
This is because you are given the measure of the opposite angle and the adjacent side.
All you have to do is 14*.30 which equals to $4.20
