The answer is x equals -3
Answer:
{x,y} = {2,7}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = -4x + 15
// Plug this in for variable y in equation [2]
[2] 3x + 5•(-4x+15) = 41 [2] -17x = -34
// Solve equation [2] for the variable x
[2] 17x = 34 [2] x = 2
// By now we know this much :
x = 2 y = -4x+15
// Use the x value to solve for y
y = -4(2)+15 = 7

Step-by-step explanation:
it's blury.
The measure of the acute angle that the wire makes with the ground is 63.27°.
The situation forms a right angle triangle.
<h3>How to find the angle of a right triangle?</h3>
The length of the wire is the hypotenuse of the right triangle.
The distance from the foot of the pole is the adjacent side of the right triangle.
Therefore,
cos ∅ = adjacent / hypotenuse
cos ∅ = 18 / 40
cos ∅ = 0.45
∅ = cos⁻¹ 0.45
∅ = 63.2563160496
∅ = 63.27°

The counting principle is applied for this problem. There is only one possible combinations for the first two digits: 12. There are four possible combinations for the third digit: 7, 8, 9, 10. There are three possible combinations for the fourth digit: 3, 6, 9. There are three possible combinations for the fifth and sixth digits: 31, 62, 93.
So all in all, 1(4)(3)(3) = 36.
