22. y=-1/2x+4
23. y=3/4x+1/2
Step-by-step explanation:
Answer:
2.5
Step-by-step explanation:
The fraction for -4.8 is -8/10
So if $42 was 70% of the original price that means you saved 30% so work out 30% of $42 then add it to the $42 = $12.60 + $42
When the inequality sign is < / > (less than/greater than), the line is a dotted line.
When the inequality sign is ≤ / ≥ (less than or equal to/greater than or equal to), the line is a solid line.
If "y >" (y is greater than.....), the shaded area is above the line.
If "y < " (y is less than....), the shaded area is below the line.
[points in the shaded area are solutions for the inequality. If the point is on the line and the line is ≤ / ≥, it is a solution]
- The point outside of the blue shaded area is not a solution because it has to be in the shaded area.
- The point on the line is not a solution because the line is a dotted line, which means that the point can't be equal to the points on the line.
- The point inside the blue shaded area is a solution.
