Answer:
b = 5
Step-by-step explanation:
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = C(1, 3) and (x₂, y₂ ) = D(4, - 3)
m = =
= - 2, hence
y = - 2x + b ← is the partial equation of the line
To find b substitute either of the 2 points into the partial equation
Using (1, 3), then
3 = - 2 + b ⇒ b = 3 + 2 = 5
Answer: The largest dimensions that are possible would be 50 foot by 125 foot.
Step-by-step explanation:
Since we have given that
Amount a farmer has available = $1500
Let x be the side perpendicular to the river.
Let y be the side parallel to the river.
Number of section perpendicular to the river = 3
cost of material for the side parallel to the river = $6 per foot
Cost of material for the side perpendicular to the river = $5 per foot
So, total cost becomes
Area would be
Now, put A' = 0 to get the critical points.
So, it becomes,
so, at x= 50 it will give maximum dimensions.
So, the largest dimensions that are possible would be 50 foot by 125 foot.
Question 1:
For this case we must rewrite the following equation:
If we add 3x to both sides of the equation we have:
Thus, we have that an equivalent expression is option C.
Answer:
Option C
Question 2:
For this case we must solve the following equation:
Subtracting 5 from both sides of the equation we have:
Dividing between -5 on both sides of the equation we have:
Answer:
Option B
