Answer:
270 flowers total she sell Together.
Step-by-step explanation:
According to the Question,
- Given, A florist arranges some orchids in bouquets of 20 and some roses in bouquets of 10.
Let, x = number of orchid bunches & y = number of rose bunches.
-
Now, She sells each orchid bouquet for $25 and each rose bouquet for $30. She earns a total of $390
Therefore, 25x + 30y = 390 ⇒⇒ Equation 1
she sells 4 times as many orchid bunches as rose bunches,
Therefore, x = 4y ⇒⇒ Equation 2
- Put The Value Of Equation 2 in Equation 1, We get
25 × (4y) + 30y = 390
100y + 30y = 390
130y = 390 ⇔ y = 390 / 130 ⇒ 3
if y = 3, then x = 4y must be equal to x= 12.
Thus, she sold 12 orchid bunches and 3 rose bunches.
- Verify, 25x + 30y = 390 ⇔ 12 × 25 + 3 × 30 = 390 (All okay)
Now, Each orchid bunch contains 20 flowers and each rose bunch contains 10 flowers.
- 12 × 20 + 3 × 10 = 240 + 30 ⇔ 270 flowers total she sell Together.
Answer:
A. 10
Step-by-step explanation:
As we know that
The length of the major axis of the ellipse is 10
i.e
2 a = 10
Also, the ellipse is the curve that consists of 2 focal points in order that the total of the distance to the 2 focal points would remain constant for each and every point displayed in the curve
Now we assume that P is the curve point
So,
PF1 + PF2
i.e
2 a (blue line) + (red line)
2 a = 10
Therefore the sum of the length is 10

sorry for not showing the step :(
For this case what you must do is to graph both lines. (See attached graph) and see where both are cut.
We note that both lines are cut at the point (2,5)
Therefore the solution for f (x) = g (x) is x = 2
answer x = 2
