Answer:
It has one solution (1,0)
Step-by-step explanation:
y = -2x + 2
y = 4x -4
Substitute the y's
4x - 4 = -2x + 2
Let's move the variables to one side
4x - 4 = -2x + 2
+2x +2x
6x - 4 = 2
Lets move the constant to the other side
6x - 4 = 2
+4 +4
6x = 6
Divide both sides by 6
6x/6 = 6/6
x = 1
Let go back to y = -2x + 2
Substitute the x with 1
y = -2(1) + 2
y = -2 + 2
y = 0
Answer:
15 people voted yes and 3 people voted no.
Step-by-step explanation:
Given that:
Ratio of yes to no = 5 : 1
Total number of board members who voted = 18
Let,
x be the number of times.
5x+x = 18
6x = 18
Dividing both sides by 6
People who voted yes = 5(3) = 15
People who voted no = 3
Hence,
15 people voted yes and 3 people voted no.

Here you would use right triangle trig (SOH CAH TOA)
So first draw a right triangle. Imagine youre standing at the angle opposite the right angle which is the one on the ground.This angle is the 41°. Now Imagine the balloon is as the angle above the right triangle. Well since the balloon is 1503 m from his location this would be the hypotenuse. SInce we are trying to find the height (x) we would use sine since
sine = opposite/hypotenuse . Now lets solve make sure calculator is in degree mode:
sin41 = x/1503 multiply both sides by 1503 to cancel it out
1503sin41 = x plug into calculator
x = 986.057 ft
The balloon is 986.057 feet above the ground.
