You drive from San Antonio to Houston, 1/3 the time at 20 mi/h and the other 1/3 at 68 mi/h, and the last 1/3 at 52mi/h. On the way back you travel one-half the distance at 35 mi/h and the other half at 55 mi/h. What is your average speed a) from San Antonio to Houston, b) from Houston back to San Antonio, and c) for the entire trip

add 5 subtract 1

step-by-step explanation:

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
