Answer:
X-int: (1/2 , 0) . Y-int: (0 , 4)
Step-by-step explanation:
FOR X
To find the x-intercept, substitute in 0 for Y and solve for X.
0 = -8x + 4
1. Move 4 to the left side so it's -4 = -8x
2. Divide by -8 to isolate X so it's -4/-8 = x
3. The negatives cancel out and become positive
4. Answer: X = 1/2
FOR Y
To find the y-intercept, substitute in 0 for X and solve for Y.
Y = -8(0) + 4
1. Since anything multipled by 0 is 0, it simply becomes Y = 4.
Answer: Y = 4
In a 30-60-90 triangle, the side lengths are in the ratio 1:2:sqrt(3) = short leg: hypotenuse: long leg.
We know the hypotenuse is 8. We can use this to find the other legs.
The short leg s is 8/2 = 4 because the short leg is always half of the hypotenuse.
The long leg q is 4 * sqrt(3), because the long leg is always sqrt(3) times the shorter leg.
So:
s = 4
q = 4 * sqrt(3)
Y = 168° [ Because opposite angles are equal ]
x = 5x - 48 [ Because opposite angles are equal ]
4x = 48
x = 12°
Answer:
x=1
Step-by-step explanation:
Since both lines have 1 as it x value, x=1 is the line
