Isolate x in 2nd equation...
-x - 2y = -10 ....add 2y to both sides
-x = 2y - 10 ...multiply by -1 to make x positive
x = -2y + 10 <== u would sub in -2y + 10 in for x in the 1st equation
Yes, this is a linear equation with a constant rate of change (a slope) so the sets of values of the graph are proportional
Answer:
Step-by-step explanation:
Any cut plane parallel to the parallel faces will create a cross section congruent with the parallel faces. The faces are triangles, so the cross section is a triangle.
Answer:
Asanji drove for 
hours before Huong caught up
Step-by-step explanation:
Let the time for which Asanji drove alone is "X" hours
Asanji and Huong met after three hours of driving of Huong.
Total time for which Asanji drove 
hours
Thus, distance travelled by Asanji in 
hours is equal to distance travelled by Huong in 
hours
On solving the above equation, we get -
Asanji drove for 
hours before Huong caught up
