Answer:
The value of x if the equation is
3x + 4y=65
x = 49/3 or 16.3
&
3x - 4y=65
x= 27
(a) - 5
since y varies inversely as x then k = yx ( k is the constant of variation )
using y = 5 when x = - 1, then k = 5 × - 1 = - 5
Answer:
Step-by-step explanation:
Given:
Slope which is , that is
Line containing , that is
We need to write an equation in point slope form for the line.
Solution:
As we know that
As we know the equation of line in point slope form is
Let us know plug the value:
⇒
Hence, the equation in point slope form for the line that has a slope of is .

Statements 1,4&5
Step-by-step explanation:
A hole is when both, numerator and denominator, of a fraction become 0 (zero).
This would happen when the numerator and denominator have a common factor.
Example:
(2x+4)/(x+2)
= [2(x+2)]/(x+2) = 2
Although the fraction can be simplified, there's a hole at x = -2.
x = -2 will not be part of the domain.
The hole is represented by an open circle.
I think you would expand it like this but I am not 100% positive.
(69 * -7) * (69 * 9)
