Answer:
y = -1/3x + 6
Step-by-step explanation:
the slope is -1/3 because you find the the reciprocal and switch the sign. To find the y intercept you plug in the points to the equation.
5 = -1/3(3) + b
5 = -1 + b
6 = b
Step-by-step explanation:
they are definitely rational numbers
Answer: b) x = 6 and total line is 52
c) x = 5.5 and total line is 20
Step-by-step explanation:
b) (x+20) = (5x-4)
4x = 24
x = 6
Line (x+20) = 26
Line (5x-4) = 26
Total line = 52
c) (4x-12) = (-2x+21)
6x = 33
x = 5.5
Line (4x+12) = 10.0
Line (-2x+21) = 10.0
Total line = 20
Answer:
4 inches
Step-by-step explanation:
First, we find how much fits into one inch of soil. We do this by multiplying 4 by 3. This equals 12. For every 12 cubic inches, the soil will be one inch deep. We divide 48 by 12 to see how many inches deep is it. This equals 4. The soil is 4 inches deep.
