Do the rainbow method
x^2 - 6x + 2x - 12
Now simplify
x^2 - 4x - 12
The answer is x^2-4x-12
Answer:
x=-16
Step-by-step explanation:
from x=-3 to get to y=12 u need to multiply x=-3 by -4 to get to 12 so for y=64 u need to divide by -4 which equals x=-16
Equation of the line is y = 4x + 4
Step-by-step explanation:
- Step 1: Given that the line passes through (2,4) and (1,0). Equation in slope-intercept form is y = mx + b
- Step 2: Find slope, m using the formula m = (y2 - y1)/(x2 - x1)
⇒ m = (0 - 4)/(1 - 2) = -4/-1 = 4
- Step 3: Find the y-intercept.
⇒ b = 4
- Step 3: Substitute the values in the equation
⇒ y = 4x + 4
Well 1/2 of a song = 1/8 of a minute then
1/2 x 2 = Full length song
1 = (1/8 x 2)
1 = 1/4
He will need 1 quarter of a minute. Which is 15 seconds.
Happy studying ^-^
