A. For y= 2x-1, the slope is 2 and the y intercept is -1. Therefore, we should first plot (0,-1). From there, for each increment of x, increase y by 2. For y= 4x-5, the slope is 4 and the y ntercelt is -5. Therefore we should plot (0,-5) and plot an increase of 4 on the y axis per increase of 1 on the x axis. The solution is where the lines cross.
B. (2,3)
Answer:
93
Step-by-step explanation:
15 x 5 = 75 + 18 = 93
Answer:
40
Step-by-step explanation:
x = (180-100)/2 = 40
Answer:
3x=42
Divide 3x to both sides
14=x
56=8x
Divide 8 to both sides
7=6
6x+4=40
subtract 4 to both sides
6x=36
divide 6 to both sides
x=6
58=4x-6
add 6 to both sides
64=4x
divide 4 to both sides
16=x
