Answer:
(-2,4)
Step-by-step explanation:



This implies
.
This means
and
.
Subtract 3 on both sides for first equation:
.
Add 3 on both sides for the second equation:
.
So the pre-image (x,y) is (-2,4) if the image is (1,1).
Let's check:



So the solution has been checked and verified.
As the focus is at (0,5) it will be symmetrical about the y axis and will open upwards
General formula is x^2 = 4ay where a is the y coordinate of the focus
So its y = x^2/5*4
y = 1/20 x^2
Answer:
7 Months
Step-by-step explanation:
x=number of months
how much is deducted total=number of months times amount deducted per m onth
amount deducted per month=45
number of months=x
how much deducted total=45x
460-deducted total is more than 100
460-45x>100
solve for x
add 45x to both sides
460>100+45x
subtract 100
360>45x
divide both sides by 45
8>x
answer is 7 months
if he does 8 months, then he will have exatly 100 and 100 is noe more than 100
Answer:
487.1
Step-by-step explanation:
100+100=200
200-3=197
197+6=203
203-0.5=202.5
202.5+41=243.5
243.5+0.2=243.7
243.7×2=487.1
