Answer:
Use the slope-intercept form y=mx+b to find the slope m. m=−1
Step-by-step explanation:
lets take the x's away from: -5x+4x
That will be -5+4
-5+4=-1
Because remember:
When adding positive numbers, count to the right.
When adding negative numbers, count to the left.
When subtracting positive numbers, count to the left.
When subtracting negative numbers, count to the right.
I hope this helps. :)
Well you could factor it by dividing the entire equation by two...
x^2+8x-5=0
The answers should be A and E! Hope it helps!
it dropped from 0 to -20
-20 -0 = -20
divide by the time of 5 hours
-20/5
-4 degrees per hour
