Find an equation for y in terms of x
Answer:
y = [tex]\frac{9}{x^2}[/tex]
Step-by-step explanation:
Given y is inversely proportional to x² then the equation relating them is
y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of proportion
To find k use an ordered pair from the table
Using x = 3 when y = 1 , then
1 = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )
9 = k
y = [tex]\frac{9}{x^2}[/tex] ← equation of proportion

Name each transformation correctly as a Translation, Dilation, or Reflection.
WILL MARK BRAINLIEST IF CORRECT!!!!!!
Answer:
Translation
7, 18, 19, 20Dilation
9, 10, 17Reflection
7, 8 , note 7 has both reflection and translationUse the given x and y values to write a direct variation
equation. Enter your answer in the form y = kx.
x = 5, y = 50
The form is y = kx
Replace y and x:
50 = k(5)
Solve for k by dividing both sides by 5
K = 10

A boat travel 448 km using 112 litres of gasoline.How far can the boat travel using 1 litre of gasoline
Divide total distance by total liters used.
448 km / 112 liters = 4 km per liter.
Using 1 liter of gas the boat can travel 4 km.
Answer:
1 litre = 4 km
Step-by-step explanation:
448/112 = 4/1
Cross multiplication, 448 x 1 divided by 112 = 4
It took a car 4 days to travel 2686 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)
Answer:
28
Step-by-step explanation:
Well we know that in a day there are 24 hrs so in 4 days there will be 96 hrs
so the car travelled 2686 miles in 96 hours
2686/96= 27.9791666667
So the car's average speed is about 28

Answer:x=45.6
Step-by-step explanation:
Answer:
(x^2 - 5x^2 + 4x) / 2x + 8
Step-by-step explanation:
(x^2 - 16) / 2x + 8 * (x^3 - 2x^2 + x) / (x^2 + 3x -4)
(x^5 - 2x^4 - 15x^3 + 32x^2 -16x) / 2(x - 1)(x + 4)(x + 4)
x(x-1)(x-1)(x+4)(x-4) / 2(x - 1)(x + 4)(x + 4)
(x^3 -5x^2 +4x) / 2x + 8

Jessica is returning home from a trip. The function d(t)=458-60t models the distance, in miles, that Jessica is from her house t hours after she began returning home. How far is Jessica from her home 5 minutes after she began returning home?
A.
5 miles
B.
158 miles
C.
300 miles
D.
453 miles
Answer: D. 453 miles .
Step-by-step explanation:
Given: The function [tex]d(t)=458-60t[/tex] models the distance, in miles, that Jessica is from her house t hours after she began returning home.
At t = 5 minutes = [tex]\dfrac{5}{60}[/tex] hour [1 hour = 60 minutes],
Distance covered by Jessica in 5 minutes = [tex]d(\dfrac{5}{60})=458-60(\dfrac{5}{60})[/tex]
[tex]=458-5=453\ miles[/tex]
Jessica is 453 miles from her home after 5 minutes she began returning home.
Hence, the correct option is D. 453 miles .
