How would I solve Part B?
1 answer:
Answer:
D (-4, -9)
Step-by-step explanation:
midpoint formula:
(x₁ + x₂) / 2 , (y₁ + y₂) / 2
plug in C (2,7)
(2 + x₂) / 2 , (7 + y₂ ) / 2 = (-1, -1)
(2 + x₂) / 2 = -1
multiply each side by 2
2 + x₂ = -2
subtract 2 from both sides
x₂ = -4
(7 + y₂) / 2 = -1
multiply each side by 2
7 + y₂ = -2
subtract 7 from both sides
y₂ = -9
D (-4, -9)

Answer:
C=25d
Step-by-step explanation:
We write an equation where C or cost is my output and d or days is my input. I should be able to put in any number of days and find the cost. Let's gather some data:
River Ramble
Day 1 $25(1)=25 cost
Day 2 $25(2)=50 cost
Day 3 $25(3)=75 cost
Day d $25(d)=C.
Our equation is C=25d.
3(4x-3)(x+6) is the answer

Answer:
n=−5
Step-by-step explanation:
n−4−3n=3n+6−3n
−2n−4=6
Step 2: Add 4 to both sides.
−2n−4+4=6+4
−2n=10
Step 3: Divide both sides by -2.
−2n
/−2
= 10
/−2
n=−5
The slope is 2x. In other words 2/1
