Answer:
y= -9x+14
Step-by-step explanation:
the equation of a straight line is y=mx+c
m is the slope
And we are given a y and x term
So we substitute these into the equation:
5= -9(1) + c
rearragne to find c
14= c
so the full equation is:
y= -9x+14
The discriminant of this equation is 49. The solutions for this equation are x=2 and x=-

I hope that helps.
It's a rational number because 25 is perfect square, taking the square root gives the rational integers +5 or -5
Answer:
2×2×3×3×3
Step-by-step explanation:
●108=
•2×54
•2×27
•3×9
• 3×3
Writing the prime numbers;
108=2×2×3×3×3
Based on the way these stations are connected, we can infer that there are <u>56 tubes. </u>
<h3>Number of tubes in Spaceland </h3>
Each pair of stations have 2 tubes. This means that every station is connected to each of the others.
We can therefore infer that each station has 7 tubes to the other stations.
The total number of tubes would therefore be:
= Number of stations x Number of tubes per station
= 8 x 7
= 56 tubes
In conclusion, there are 56 tubes.
