Answer:
50.3
Step-by-step explanation:
<span>So we wan't to know what is the selling price of a motorcycle if the starting price was 2499$ and the discount was 249$. To get the selling price we need to subtract the discount from the starting price: 2499$-249$ = 2250$. So the selling price is 2250$.</span>
Answer:
f(4) = -15
Step-by-step explanation:
Since we have an average rate of change, we can deduce that a line, with a gradient of -6 joins the points on the function, f, when the parameter is 1 and when it is 4, i.e. the line passes through the point (1, 3) and has a gradient of -6;
From this, we know that for every value of x we increase the, value y will decrease by 6;
So if we increase 1 by 3, to get to 4, the y value must decrease by 18 (3×6);
Written mathematically, it would look like:
f(4) = 3 + (4 - 1)(-6)
= 3 - 18
= -15
(4, -15)
Answer:
14. 12x + 2y
16. -2x - 4y
18. -8x + 10y
Step-by-step explanation:
<h3><u>
Don't stress it.</u></h3>
All you need to do is add the x's with the x's and add the y's with the y's.
The same applies with subtraction.
<u><em>Note: </em></u>
positive + positive = positive
negative - negative = negative
