Answer:
4
Step-by-step explanation:
HK is double of HW, so:
Then solve. Divide both sides by 2.
21=x²+5
16=x²
4=x
I hope this helps and good luck on the rest of your HW
Answer:
Step-by-step explanation:
Slope intercept form: when is the slope of the line and is the y-intercept (the y-coordinate of the point the line crosses the y-axis)
<u>1) Find the slope (</u><u>)</u>
when the points are and
We can use any two points that the table gives us to plug into this equation. For example, we can use the points (14,0) and (0,7):
Simplify the fraction
So far, our equation looks like this:
<u>2) Find the y-intercept (</u><u>)</u>
The y-intercept is the y-coordinate of the point the line crosses the y-axis, or in other words, it's the value of y when x is equal to 0.
Looking at the table, we can see that y is equal to 7 when x is equal to 0, so, therefore, .
Now, this is our final equation after plugging in and :
I hope this helps!
For this case, the first thing we must do is define a variable.
We have then:
x: additional amount of weight that Li can add.
We write now the inequality that represents the problem.
We have then:
Answer:
An inequality that can be used to determine how much more weight can be added to the suitcase without going over the 50-pound weight limit is:
