2 3/5 - 1 1/3 = 2 6/15 - 1 5/15 = 1 1/5
Answer:
The slope of a line perpendicular to this line would be 2/7 and the slope of a line parallel to this line would be -7/2.
Step-by-step explanation:
In order to find these, we first need to solve the equation for y.
7x + 2y = 1
2y = -7x + 1
y = -7/2x + 1
Now we can see the original slope is -7/2 due to it being the coefficient of x. We know parallel lines have the same slope, so the parallel slope is simple -7/2.
We also know perpendicular slopes have opposite and reciprocal slopes. So we take the -7/2 and change the sign (giving us 7/2). Then we flip it to get 2/7.
Answer:
63cm³
Step-by-step explanation:
The shape above is a rectangular prism
The formula for a rectangular prism is given as:
= Length × Width × Height
Length = 3cm
Width = 3cm
Height = 7cm
= 3cm × 3cm × 7cm
= 63 cm³
The volume of the rectangular prism = 63cm³
Step-by-step explanation:
negative because it's a negative number until it gets a full ratio unit or positive unit
