Answer:
b = quantity of boards purchased
p = quantity of posts purchased
equation: 4b + 6p = 58
Step-by-step explanation:
|13-6| < x < |13+6|
So the range will be:
7 < x < 19
Answer:
y = -9x +3
Step-by-step explanation:
Slope = -9
y intercept = 3
We can use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -9x +3
-2/3x +1/3 +x = 2/5
⇒ 1/3x + 1/3 = 2/5
⇒ 1/3x = 2/5 -1/3
⇒ x/3 = 1/15
⇒ 15x = 3
⇒ x = 3/15
⇒ x = 1/5
