Answer:
x-intercept: (-3,0)
y-intercept: (0,-3)
Step-by-step explanation:
Looking at the equation, we can see that it is already in standard form, or in a 
format. Whenever a line is put into standard form, the x-intercepts are represented by 
and the y-intercepts are represented by 
. So, let's calculate them by doing the following:
1) Find the x-intercept by using the formula. Substitute the number on the right side of the equation for 
and the coefficient for the x term for 
. So, in this case, 
and 
:
Therefore, the x-intercept is (-3,0).
2) Next, find the y-intercept by using the 
formula and substituting the right values. is still the number on the right side of the equation and 
is the coefficient of the y term. So, and 
.
Therefore, (0, -3) is the y-intercept.

Just for your reference, this question will get unlimited number of solutions, attached is a few examples I calculated from Excel. Have fun to pick one or create one to be your favorite.
Answer:
200%
Step-by-step explanation:
If $40 is 100% then multiply it by 3 to get $120
Answer:
$12.72 or $25.44
Step-by-step explanation:
if he buys 2 tickets that are $12 each. half of 12 is 6 so you will have to pay 12 plus tax(6%). to find tax you would multiply 12 x .06 which would be $12.72. if it say the tickets are half off from $24 being $12 each then the answer would be $25.44. the question dosent specify that.
hope i helped
We have that
(x + 3)² = -20(y − 1)
<span>This is actually the vertex form, so we can obtain the vertex already
</span>the vertex is the point (h,k)------------> (-3,1)
4p=-20------------> p=-5
Focus is at (-3,1-5)---------> (-3,-4)
Directrix is at <span>y = 1-(-5)----------> y=6
</span>
the answer is
the directrix is y=6
see the attached figure
