4 up, 1 left or (+4,-1) 4/-1= -4
Answer:
x>-1.25
Step-by-step explanation:
3(5x-10)<30x
15x-20<30x
-20<15x
-20/15<x
-1.25<x
x>-1.25
Answer: f(x) = –3x + 14
Step-by-step explanation:
The point slope form of an equation is expressed as
y - y1 = m(x - x1)
The given equation is
y + 1 = –3(x – 5)
Comparing with the point slope equation,
y1 = - 1
Slope, m = - 3
x1 = 5
The equation of a straight line can also take the slope intercept form,
y = mx + c
Where
m is the slope(change in y /change in x)
c represents the intercept.
We would determine the intercept by substituting x = 5 , y = -1 , m = - 3, into y = mx + c. It becomes
- 1 = - 3 × 5 + c
- 1 = -15 + c
c = - 1 + 15 = 14
The equation becomes
y = -3x + 14
Answer:
1/4
Step-by-step explanation:
1 hour 15 minutes = 75 minutes
25 mins + 75mins = 100 minutes
25/100 minutes x 100 = 25%
25% = 1/4 of the time was spent reading.
