Answer:
B. y=-2x+4
Step-by-step explanation:
to get to each point you go up 2 to the left 1, up is positive as if u go up in the graph you go y+1 left is negative as to go left you go x-1 so 2/-1 is m(the slope) or -2. now find the y intercept is the point where x and y cross at x=0 which is 4. put it together and you have y=-2x+4
Answer:
The slope is 1/2
Step-by-step explanation:
If you watch where each dot landes, it's half of each y number. The sodas cost $0.50 which is half of 1.
Answer:
0.75, or 3/4. same thing.
Step-by-step explanation:
divide both sides by 3 on a calc. easy!!!!
Answer:
you need to show the line graph.... or is there not one
Step-by-step explanation:
Answer:
Option H
Step-by-step explanation:
Perimeter of rectangle= 2(length) +2(width)
100= 2(5a -22) +2[½(a +1)]
Expand:
100= 2(5a) +2(-22) +a +1
100= 10a -44 +a +1
Simplify:
100= 11a -43
+43 on both sides:
11a= 100 +43
11a= 143
Divide both sides by 11:
a= 143 ÷11
a= 13
Thus, option H is correct.
