2 answers:
X=7 y=5 You need to used the second equation and isolate either x or y. It’s your choice. Then, use that and substitute it in for the first equation. Then you will get an integer and substitute it back to the second equation.
Answer:
x=7 y=5
Step-by-step explanation:
3x+6(40-5x)=51
3x+240-30x=51
-27x+240=51
-27x=-189
27x=189
x=7
y=40-5(7)
y=40-35
y=5

Answer:
the temperature is 58⁰F
Answer:
would it be zero because when you try to find the equation its just 0 so it would be y=3
Step-by-step explanation:
as you can see both the points are at 3. so i would say y=3
Answer:
little blurry but i think its 3

Answer:
-1
Step-by-step explanation:
The slope formula works nicely for this.
m = (y2 -y1)/(x2 -x1)
m = (-1 -4)/(4 -(-1)) = -5/5 = -1
The slope of the line between the given points is -1 .
