I'm sorry try to reread what you learnt in class
I'm not up to this yet
Answer:
y=-1/2x+2
Step-by-step explanation:
for x-intercept
put y=0
0= -1/2x+2
1/2x=2
x=4
(4,0)
for y-intercept
put x=0
y= 2
(0,2)

Answer:
0.5x+20=0.25x+30, m=40
Step-by-step explanation:
Blue: y=0.5x+20
Red: y=0.25+30
We’re looking for where the y (cost) is equal, so we can set the two equations to each other:
Isolate x:
0.5x+20=0.25x+30
0.5x+20-20=0.25x+30-20
0.5x=0.25x+10
0.5x-0.25x=0.25x+10-0.25x
0.25x=10
x=40
m= 40
17x + 13 + 8x - 8 = 180
25x + 5 = 180
25x = 175
x = 7
/_A = /_C = 8(7)-8 = 56-7 = 49
