Answer:
see explanation
Step-by-step explanation:
A rational number can be expressed in the form
where a and b are integers
Given
- 27 = 
← in rational form
Thus - 27 is a rational number
Answer:
No
Step-by-step explanation:
To determine if (- 5, - 5) is a solution
Substitute x = - 5 into the inequality and compare answer to y
- 2(- 5) + 4 = 10 + 4 = 14 > - 5 ← the y- coordinate
Thus (- 5, - 5) is not a solution to the inequality
Answer:
7y+5x=76
Step-by-step explan
A (-4,8) and B (6,3)
First find the slope;
m= (y2-y1)/(x2-x1)
m=(3-8)/(3+4)
m=-5/7
now using equation of line
y-y1= m(x-x1)
y-8=-5/7 (x+4)
y-8=(-5x+20)/7
7(y-8)= -5x+20
7y-56=-5x+20
7y+5x=20+56
7y+5x=76
