8 sand bags
Step-by-step explanation:
300 - 140 = 160
160 ÷ 20 = 8
8 sand bags of 20-pounds each.
Answer:
m = -1/3
Step-by-step explanation:
y = 3x-4
This is in slope intercept form
y = mx+b m is the slope and b is the y intercept
The slope is 3 and the y intercept is -4
We want the slope of a line that is perpendicular
Perpendicular lines have slopes that multiply to -1
Let m be the slope of the line that is perpendicular
3 * m = -1
Divide each side by 3
3m/3 = -1/3
m = -1/3
Answer:
slope = (1 -(-3)) / (1-0) = 4/1 = 4
Step-by-step explanation:
the function is linear, so the rate of change is constant. Another word for rate of change is slope. The slope of the line is 4.
y = mx + b (m is the slope; b is the y-intercept)We can do the math if your teacher wants.
f(x) = 4x -3
f(1) = 4 -3 = 1
f(0) = 0 -3 = -3
slope = (1 -(-3)) / (1-0) = 4/1 = 4
