Answer:
you also have to translate 3 units to the right
Step-by-step explanation:
when you finished your reflections the coordinate of the point is (1, -1) while it should be (4, -4), that means you not only need to move it by 3 down but also to the right.
Y=-9x+4
-9x represents the slope . 4 is the initial value/y-intercept
Answer:
True
Step-by-step explanation:
Because angles on a straight line are supplementary and these anglea <1 and <2 are supplementary angles
Um so is there a specific question u would like me to help u
<u>Part (a) : The cost of ordering 25 announcements.</u>
we need to substitute with x=25 in the middle function which is {1.25x+15}
so, the cost of ordering 25 announcements = 1.25 * 25 + 15 = $46.25
<u>Part (b) : The cost of ordering 24 announcements.</u>
we need to substitute with x=24 in the upper function which is {1.5x+15}
so, the cost of ordering 24 announcements = 1.5 * 24 + 15 = $51
<u>Part (c): what number of announcements less than 25 is it financially better to purchase 25 announcements?</u>
We need to find x which will give c(x) is greater than $46.25 and less than or equal $51
By graphing the function and making the the boarders of c(x) at $46.25 and $51
The intersection with the function {1.25x+15} will give us the value of x which is 21 and 24
So, The number of announcements less than 25 is financially better to purchase 25 announcements: <u>21 ≤ x < 25</u>
