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:
$4,292
Step-by-step explanation:
16 x 14.5 = 232
18.50 x 232 = 4,292
Answer:
Step-by-step explanation:
9/4x + 2 = 20
To get x by it's self you do the same on both sides of the = to cancel out each side.
9/4x + 2 = 20
(Multiply 9 on both sides)
4x + 2 = 20*9
(Now subtract 2 from both sides)
4x = 20*9 - 2
And finally divide both sides by 4
x = (20*9 - 2)/4
Then solve for x as normal.
Answer:
y-intercept: (0,3)
Step-by-step explanation:
To find the y-intercept, we set x to equal 0, giving the equation:
-3(0)+2y = 6
0+2y = 6
y = 3
Using proportions, it is found that the children made 408 snowflakes on the third day.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
On the first day, they made 30% of the total amount of 1,200, hence:
D1 = 0.3 x 1200 = 360
On the second day, they made 20% more day in the first, hence:
D2 = 1.2 x 360 = 432.
On the third day, they made the remaining amount, hence:
D3 = 1200 - (360 + 432) = 408.
