Answer: y = -5x + 20
Step-by-step explanation:
Remember that : y=mx+b
y = (-5)x + b
Now you can plug your coordinates (-7,8) into that equation.
8 = (-5)-7 + b
Solve for b
8 = -12 + b
Add +12 to both sides of your equation:
20 = b
Now, your new equation is:
y = -5x + 20

incomplete question
What is the y-intercept of this equation?
y= 2/9x +13
Answer:
13
Step-by-step explanation:
y=mx+b
b= y-intercept
Answer:
13
Step-by-step explanation:
The classic equation looks like y=mx+b . In your case, 2/9 is m and 13 is b. M means the slope, and b means the y-intercept.

Candy is on sale for $0.75 each. You have a coupon for $0.25 off your total purchase.
Write a function rule for the cost of n pieces of candy.
A. C(n)= 0.25n-0.75
B. C(n)= 0.75n-0.25
C. C(n)= 1.0n
D. C(n)= 0.75n
Which one is it?
Answer: B. C(n)=0.75n-0.25
Hope these helped u :)
Step-by-step explanation:
Answer: I believe it's B because 1 candy bar=0.75 but there's a $0.25 percent off so I think 0.75n-0.25 would be the right answer

The function f(x) = 2x^2 + 3 represents the rate of a boat traveling with the current in miles per hour.The function g(x) = x+2 represents the time the boat traveled in hours. Solve (f x g) (2), and then interpret the answer (f x g)(2) = 15, the distance in miles the boat traveled
(F times G) (2) = 15, the distance in miles the boat traveled
(F time G) (2) = 15, the number of boats
(F times G) (2) = 44, the distance in miles the boat traveled
(F times G) (2) = 44, the number of boats
Answer:
Step-by-step explanation:
Answer:
The distance travelled by the B737-400 aircraft in 5 hours is 2,000 miles
Step-by-step explanation:
Average speed = 400 miles per hour
Distance = 400t
t= 5
Total distance = 400t at t hours
Total distance when t = 5 hours
Total distance travelled = 400t
= 400 × 5
= 2,000 miles
Total distance travelled = 2,000 miles
The distance travelled by the B737-400 aircraft in 5 hours is 2,000 miles

The cylindrical part of a architectural column has a height of 325 cm and a diameter of 30 cm. Find the volume of the cylindrical part of the column. Use 3.14 for π and round your answer to the nearest cubic centimeter if needed.
Answer:
[tex]V=229612.5\ cm^3[/tex]
Step-by-step explanation:
Given that,
The height of a cylinder, h = 325 cm
Diameter, d = 30 cm
Radius, r = 15 cm
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2h[/tex]
Putting all the values,
[tex]V=3.14\times (15)^2\times 325\\\\V=229612.5\ cm^3[/tex]
So, the volume of the cylinder is [tex]229612.5\ cm^3[/tex].

Answer:
x=6
Step-by-step explanation:
to solve this equation, we need to isolate the variable (x).
to do this we must subtract both sides by 8.
doing this we get:
4x=24
now we need to divide both sides by 4:
x=6

Suzi starts her hike at 220 feet below sea level. When she reaches the end of the hike, she is still below sea level at −107 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the hike?
The change was____ feet.
Answer: 113 feet.
Step-by-step explanation: Even though Suzi was still below sea level at the end of the hike, she still climbed 113 feet higher.
-220 - (-107) = c-220 + 107 = c-113 = cThe change will be positive, though, because Suzi was climbing up, not down. Therefore the final answer is 113 feet.
Answer:
Step-by-step explanation:
Let sea level be our reference point. Suzi starts at -220 ft and ends up at -107 ft. The change in elevation is represented by x = |-220 ft - (-107 ft)|, or 113 ft.

Answer:
the slope is 3
Step-by-step explanation:
Answer:
m = -1/3
Step-by-step explanation:
You have the right idea with the rise and run. We have a run of 15 and a rise (or I guess in this case, a decline) of -5. Slope is rise over run:
-5/15 = -1/3
This means we have a slope of -1/3.
Alternatively, we could just the points and put them into the slope formula.
We have the points (0,25) and (15,20). We can substitute those values into the formula:
m = y₁ - y₂ / x₁ - x₂
m = 25 - 20 / 0 - 15
m = 5/-15
m = -1/3
Works all the same.

Which equation finds m given E, and C
Answer:
C
Step-by-step explanation:
E=mc^2
To find m, isolate m from the rest of the variables, E and C. Since m and c^2 are being multiplied, use the inverse of multiplication, division, to undo the multiplication.
E/c^2 = m.
