Slope of a line passing through two points and
is given by,
Slope (m) =
Slope of the line passing through (-4, 3) and (6, 3) will be,
m =
m = 0
In other words, slope of any line parallel to x-axis is zero.
Therefore, Option (a) is the answer.
Answer:
897 liters
Step-by-step explanation:
The motor oil is composed of 8 liters of natural oil and 5 liters of synthetic oil. This means there is a ratio of 8/5. We have 552 liters of natural oil to y liters of synthetic. This is the ratio 552/y. Create a proportion that compares the two ratios.
Solve by cross multiplying.
8y = 5(552)
8y = 2,760
y= 345
345 liters of synthetic oil.
Together 552+345= 897 liters of motor oil.
