Rewrite the inequality as
We can compare this expression to the function
The inequality states that we want to consider all the point whose y coordinates are greater than the ones of the points that lay on the graph.
So, we can graph the inequality in two steps:
- Graph the line
- Consider all the point above the graph (greater y values means "higher")
Since the function is a line (because it is a first-degree polynomial), you can graph it by simply sampling two points: if for example we choose x=0 and x=1, the correspondent y values are
So, the line passes through the points (0,4) and (-1,2). Connect them and you have the graph of the line.
Answer:
undefined
Step-by-step explanation:
slope = ((y2-y1)/2) / ((x2 - x1 )/2)
since x1 = x2
so x2 - x1 = 0
then ((y2-y1)/2) / 0 = undefined
Answer:
100
Step-by-step explanation:
This is formula fot completing the square:
(b/2)^(2)
(-20/2)^(2)
100
Y=-13+3
y=-10
That is a horizontal line, it has a slope of zero.
The first thing we need to know is how much grass the grasshopper needs to eat.
We have:
"must eat half its body weight in grass each day":
(2 grams) * (1/2) = 1 gram
Then,
"1 blade of grass weighs 0.1grams"
Then the amount you need to eat is given by:
N = (1) / (0.1)
N = 10 blades of grass
Answer:
the grasshopper needs to eat 10 blades of grass each day
