Answer:
y = 1.25
Step-by-step explanation:
Use the direct variation equation y = kx, and solve for k:
y = kx
-10 = k(40)
-0.25 = k
So, the equation is y = -0.25x. Solve for y when x = -5
y = -0.25x
y = -0.25(-5)
y = 1.25
So, y = 1.25 when x = -5
I was taught to get a common denominator and then arrange them in the correct order.
So first you find out what all the denominations can be multiplied to. That would be 40
So you multiply the bottom of each fraction by a number that will get 40.
3/4 * 10 = 30/40
7/8 * 5 = 35/40
3/5 * 8 = 24/40
Then you get 30/40, 35/40, and 24/40.
Then you organize the m.
24/40, 30/40, and 35/40
Answer:
positive zero or negative thx me later
Well the answer is x^2 - 16x + 63
