Answer:
B. p+121 is ≤ 345
Step-by-step explanation:
Talula can't go over the amount of 345 because it would go over the limit therefore the less than or equal to sign is needed. It would be p PLUS 121 because it would be a number less than or equal to 345 and p is the variable that is has to be less than or equal to 345.
Answer:
D. y-4= -3/2(x+5)
Step-by-step explanation:
Firstly, taking two valid ordered pairs from the graph:
(-2,4) and (2,-2)
Using Delta y over Delta x, we are able to obtain m as -3/2
Next,
The following is the point-slope formula:
y-y₁=m(x-x₁)
Based on the graph, (4,-5) can be spotted as a definite ordered pair
Therefore, y-4= -3/2(x+5) fits the graph best and has the appropriate m value.
Hmm i’m not sure so figurisbzbsggs
Answer:
y = 9x/2 + 17/2
Step-by-step explanation:
Use the slope formula:
to find the slope of the line.
(4 - (-5)) / (-1 - (-3)) = (4 + 5) / (-1 + 3) = 9 / 2
y = mx + b
m is for slope, b = y-intercept
y = 9x/2 + b
Plug in one pair of the known values:
(-1,4)
4 = 9(-1)/2 + b
b = 4 + 9/2 = (8+9)/2 = 17/2
y = 9x/2 + 17/2
If you want to check if the equation is right, you can plug in the other pair of values into the equation:
(-3,-5), y = 9x/2 + 17/2
-5 = -3*9/2 + 17/2
-5 = -27/2 + 17/2
-5 = -10/2
-5 = -5
Answer:
for every 3 packages, she uses 1/2 a roll of wrapping paper
if she uses 2 1/2 rolls.....
(2 1/2) / (1/2) ....* 3
(5/2) / (1/2).....* 3
(5/2 * 2) * 3
5 * 3 =
15 packages <===
