Answer:
Height of flagpole = 571 ft
Step-by-step explanation:
Given:
Angle of elevation to the top of the flagpole is 55° .
Distance from the eyes to the base of flagpole = 400 ft.
To find the height of the flagpole.
Solution:
We can draw the situation as a right triangle as shown below.
In triangle ABC.
∠C= 55°
To find the length AB (height of the flagpole).
Applying trigonometric ratio :
Plugging in values.
Multiplying both sides by 400.
∴ 
Height of flagpole = 571 ft
Hello from MrBillDoesMath!
Answer:
x = -3, y = 0
Discussion:
5x + 5y = -15 =>
x + y = -3 => (divide both sides by 5)
x + y - y = -3 -y => (subtract y from both sides)
x = -3 - y
Substitute x = -3 - y into the top equation:
-3x - 5y = -9 =>
-3(-3-y) - 5y = 9 => ( substitute -3 -y for x)
(-3)(-3) + (-3)(-y) - 5y = 9 =>
9 + 3y - 5y = 9 => ( -*- is a + number)
9 -2y = 9 =>
9 - 9 -2y = 9 - 9 => (subtract 9 from both sides)
-2y = 0 =>
y = 0
Since x = -3 -y, x = -3 - 0 = =3

P.S. I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
Answer: First Choice. no solution
Step-by-step explanation:
<u>Given</u>
5 (x + 1) ≤ 5x + 3
<u>Expand parentheses and apply the distributive property</u>
5x + 5 ≤ 5x + 3
<u>Subtract 5x on both sides</u>
5x + 5 - 5x ≤ 5x + 3 - 5x
5 ≤ 3
5 ≤ 3 is not true, therefore, there is <u>no solution</u>.
Hope this helps!! :)
