Answer:
phoebe would have made 16 valentines
Step-by-step explanation:
Answer: (x^2)/16 + (y^2)/25 = 1
Step-by-step explanation:
According to the problem we can figure out that the center of the ellipse is (0,0).
Since the foci is (0,3) and (0,-3) we know that the value of c is 3. The major vertices are (0,5) and (0,-5) so the value of a is 5.
If we put this into the equation a^2=b^2 + c^2, we get 25=9+ b^2
We get b^2 is 16
Now since we know that the ellipse is vertical because the x value didn’t change, we know that the b^2 value comes first in the equation. Then the a^2 value which is 25.
Answer:
see explanation
Step-by-step explanation:
(a)
10x - 45 ← factor out 10 from each term
= 10(x - 4.5)
(b)
- 2x + 3 ← factor out - 2 from each term
= - 2(x - 1.5)
(c)
- x + 4 ← factor out - 1 from each term
= - 1(x - 4)
(d)
- x - 19 ← factor out - 1 from each term
= - 1(x + 19)
26/2=13
39/3=13
etc.
The constant of proportionality is 13.
y = 13x
