Your answer is 89.56 hope this helps and God bless you
I used substitution to get to this, but not fully sure if this is correct (solve quadratic)
We can't see the graph so we don't know the question
There are four quadrants in an x-y plane, Quadrant 1 consists of positive value of x and positive value of y: (+, +); Quadrant 2 consists of (-, +); Quadrant 3: (-,-); Quadrant 4: (+, -). If the x axis represents the number of hours, it should always have a positive value, and the y axis represents the temperature, it may be both positive and negative. So the possible quadrants are only quadrant 1 and 4.
Answer:
3 points on the line - (.5,3) (1,2) (1.5,1)
Step-by-step explanation:
y = -2x + 4 (1.5,1)
1 = -2x + 4 subtract 4 from each side
-3 = -2x divide each side by -2
1.5 = x
y = -2x + 4 (1,2)
2 = -2x + 4 subtract 4 from each side
-2 = -2x divide each side by -2
1 = x
y = -2x + 4 (.5,3)
3 = -2x + 4 subtract 4 from each side
-1 = -2x divide each side by -2
.5 = x
