Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20
It is impossible to determine the relationship between x and y from the question about the triangle. Hence, the correct option is D. This is because none of the sides are labelled x or y from the information provided.
<h3>What are the relationships that exist between the sides of a triangle?</h3>
It is important to note that:
The side with the highest length is the side that is opposite the biggest angle.
It is also important to note that the angle that is least will always be opposite the side that is smallest.

No, since the slopes are different
for 1 line
y = 4x - 4
slope = 4
for 2 line
4y = 24x - 96
slope = 24/4 = 6
Answer:
Step-by-step explanation:
Interest formula -
I = P × R × T
I = 3,280 × 0.3% × 9
What I basically did there wws multiply the amount of money, the simple interest, and the time.
Turn 0.3% into a decimal by dividing by a 100 which should give you 0.003
I = 3,280 × 0.003 × 9
Put that into a calculator, you get $88.56
Now, that's just the interest amount. Now you add it back to 3,280 to get the *total* amount.
3,280 + 88.56 = 3,368.56
Cathy ends us paying $3,368.56
Hope what I said made sense.
