The coordinate is (-4, 4)
Hello from MrBillDoesMath!
Answer:
41 sqrt(3)
Discussion:
My first reaction to the problem was:
sqrt(27) = sqrt ( 3 * 9) = 3 sqrt(3) and
sqrt(48) = sqrt (3*16) = 4 sqrt(3).
So...
7 * sqrt(27) + 5 sqrt(48) =
7 * (3 sqrt(3)) + 5 * (4 sqrt(3)) =
21 sqrt(3) + 20 sqrt(3) =
41 sqrt(3)

P.S. I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
0.14x + 25 = 0.19x
25 = 0.05x
x = 500

Answer:
m∠3 = 49°
Step-by-step explanation:
From the picture attached,
lines m and n are the parallel lines and line t is a transversal line intersecting these parallel lines at E and B respectively.
Therefore, ∠DEF ≅ ∠ABC [Exterior alternate angles]
m∠1 + m∠2 = m∠4 + m∠5
m∠4 = m∠5 [line s bisects ∠ABC]
50° + 48° = m∠4 + m∠4
98° = 2m∠4
m∠4 = 49°
Since, ∠4 ≅ ∠3 [Vertically opposite angles]
m∠3 = 49°
Answer: (-4, 0) and (4, 8)
Step-by-step explanation:
Looking at the graph, we can see where the line passes the parabola and can tell the solutions are (-4, 0) and (4, 8)
