Answer:
2 sunflowers
Step-by-step explanation:
Number of sunflowers that are 7 feet tall = 4
Number of sunflowers that are 5 1/2 feet tall = 2
4 - 2 = 2
Answer: B) Circle
<u>Step-by-step explanation:</u>
First, complete the square:
x² + 2x + <u> 1 </u> + y² - 8y + <u> 16 </u> = 13 + <u> 1 </u> + <u> 16 </u>
↓ ↑ ↓ ↑
(2/2) = (1)² (-8/2) = (-4)²
(x + 1)² + (y - 4)² = 30
The result is a circle whose center is (-1, 4) and radius is √30

Step-by-step explanation:

x + y = 2
x - y = 6
Solution
Just add the two equations together. The y's will drop out.
x + y = 2
<u>x - y = 6 </u> Add
2x = 8 Divide by 2
2x/2 = 8/2 Combine
x = 4 Substitute x = 4 into the top equation
x + y = 2
4 + y = 2 Subtract 4 from both sides
4-4+y=2-4 Combine
y = - 2
Answer
x = 4
y = -2
The value of a given that A = 63°, C = 49°, and c = 3 is 4 units
<h3>How to determine the value of a?</h3>
The given parameters are:
A = 63°, C = 49°, and c = 3
Using the law of sines, we have:
a/sin(A) = c/sin(C)
So, we have:
a/sin(63) = 3/sin(49)
Multiply both sides by sin(63)
a = sin(63) * 3/sin(49)
Evaluate the product
a = 4
Hence, the value of a is 4 units

X= 7
This is because of you plug in 7 for x into the equation it will give you 28-10 which is 18.
