Which equation is y = –6x2 3x 2 rewritten in vertex form? y = negative 6 (x minus 1) squared 8 y = negative 6 (x one-fourth) squ
AVprozaik [17]

The vertex form of the given equation, y = -6x² + 3x + 2, is expressed as: y = -6(x - 0.25)² + 2.375.

<h3>What is an Equation in Vertex Form?</h3>

The vertex form of an equation is expressed as, y = a(x - h)² + k, where:

(h, k) = vertex of the parabola.

Given the equation, y = -6x² + 3x + 2, factor the equation:

y = -6(x² - 0.5x) + 2

y = -6(x² - 0.5 + 0.0625) + 2.375

Rewriting the equation as perfect squares, we would have:

y = -6(x - 0.25)² + 2.375

The vertex form of y = -6x² + 3x + 2 is, y = -6(x - 0.25)² + 2.375.

HELP! I am REALLY struggling!
soldier1979 [14.2K]
16 = 1/4x + 2.5...where x stands for diameter of large gear
16 - 2.5 = 1/4x
13.5 = 1/4x....multiply both sides by 4, eliminating the 1/4 on the right side
13.5 * 4 = x
54 = x.....the large gear is 54 cm

Please help , I have no idea of how to do this
Misha Larkins [42]
Hello!

The time difference between checkpoint 1 and checkpoint 2 is an hour and a half. 
At checkpoint A, the total amount of miles driven is 120. At checkpoint B, the total amount of miles driven is 195. 
To find the amount of miles driven between checkpoint 1 and 2, you will subtract the amount of miles at checkpoint 1 from checkpoint 2:
195-120= 75

The car drove 75 miles between 1:00pm to 2:30 pm. Because the total time between the checkpoints was an hour and a half, we can divide it by three (90 minutes total). We also need to divide the number of miles (75) by three to find an accurate answer. 
90/3=30
75/3=25

The car drove 25 minutes in half an hour. Now, one hour consists of 60 minutes, so we will multiply both calculations by 2 (for the total hour and the total amount of miles driven in the hour):
30x2=60
25x2=50

The car drove 50 miles per hour between checkpoints A and B. 

I hope this helps you! Have a great day!

5/9 = ?/54 whats the answer​
Shkiper50 [21]

Answer:

30/54

Step-by-step explanation:

1st make and equation so 5/9=x/54

now cross-multiply.

5/9=x/54

(5)*(54)=x*(9)

270=9x

you can flip the equation.

9x=270 (next divide both sides by 9)

x=30

so 30/54=5/9

hope this helps :)
