Answer:
All real numbers except x=-7
Step-by-step explanation:
Since is a discontinuity in the rational function, this makes the denominator equal to 0.
Answer:
-5/2 because there is -5y/2 but we have to take coefficient only so -5/2
Answer:
1 makes this problem true
Step-by-step explanation:
-1t+14=3t+10
-1(1)+14 = 3(1)+10
-1 +14 =3+10 , 13=13
So 1 makes this problem true

Answer:
(6,2)
Step-by-step explanation:
y=-1/2x+5
y=2x-10
-1/2 x+5 =2x-10 to find the solution y=y ( point of intersection of two lines)
-1/2 x-2x = -10-5 solve for x
-5/2 x=-15
x=-30/-5=6
y=2x- 10 substitute x in the equation to get y
y=2(6)-10
y=2
