What do you notice about each solution? :
Picture 1 - They never intersect/touch.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other.
What do you notice about the graphs for each set of equations? :
Picture 1 - The lines are parallel.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other. (otherwise known as coincident lines).
What do you notice about each set of equations? :
Picture 1 - They have the same slope but different y-intercepts.
Picture 2 - Both the slopes and y-intercepts are different for each equation.
Picture 3 - They have the same slope and same y-intercept.
What generalization can you make? :
Picture 1 - When equations have the same slope but different y-intercepts they will be parallel when graphed.
Picture 2 - When the equations have different slopes and different y-intercepts they will be intersecting.
Picture 3 - When the equations are the same they will be coincident lines when graphed.
I don’t have any paper near me but on ur graph paper start at the point (1,2) and go up 1 and to the right 3 and make a point. Then go back to point (1.2) and go down 1 and to the left 3. Make a point there and draw a line and u have a graph! Hopefully this helps!
Answer: C
Step-by-step explanation:
Given 2 similar solids whose
ratio of sides = a : b, then
ratio of areas = a^2 : b^2 and
ratio of volumes = a^3 : b^3
Here the area ratio = 169 : 81, thus
side ratio = sqrt{169} : sqrt{81} = 13 : 9
Hence the volume ratio = 13^3 : 9^3
Using proportion then
frac{13^3}{9^3} = frac{124.92}{x} → C
