An easy way is to pretend that 25 is positive. 14+25= 39. If we know that the mathematical equation of positive+negative= negative, then we switch the 39 to -39.
Answer:
6:55 A. M. is the latest time he can leave his house
Answer:
B
Step-by-step explanation:
The solution is the point of intersection of the 2 lines
The lines intersect at (- 3, - 4 ), then
f(x) = g(x) has solution x = - 3
I can do like 42, my highest was 54 though
Think of the given points as endpoints of vectors.
The point (3, 1) is the terminus of the vector 3 i + j.
The point (-4, 2) is the terminus of -4 i + 2 j.
By the "triangle rule" for vector summation, the vector starting at (3, 1) and ending at (-4, 2) is the difference between these two vectors.
(-4 i + 2j) - (3i + j) = -7 i + j
