Answer: a: 543.2 b: 465.6
Step-by-step explanation:
a. find 30% of $776, which is 232.8. subtract 232.8 from 776.
b. find 40% of $776, which is 310.4. subtract 310.4 from 776
Y= -3x+7 im pretty sure this is the answer
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!
Answer:
Step-by-step explanation:
<u>Use the formula:</u>
<u />
<u>Plug in the numbers/coordinates accordingly:</u>
<u />
The sum of x and y decreased by their product...
(x + y) - xy <== ur expression
