These are like terms, meaning that they are completely the same disregarding the coefficient.
To combine like terms, add the coefficients.
16+(-12)=4
Final answer: 4x
Answer:
(4/7)÷ (3/-8). Division of fractions is the same as multiplying their reciprocals. So (4/7) x (-8/3). Now multiply the numerators together and denominators together (make sure you only use the negative sign once). (4 x -8) / (7 x 3) = -32/21
The slope is negative as it slopes to the left
using the extremities of the line:-
-(10+10 / (10 + 10) = -1
slope is -1.
"necessary"
It is not a "sufficient" condition. Another condition is that the figure be a plane quadrilateral.
55 mph...if the 1st one drove 260 miles, that's 65mph for 4 hours...1st car has to be 55mph for 4 hours to get 220 miles.
