Determine whether 3y = −7x + 8 is quadratic or not. Explain.

Mathematics

Yes, it is Quadratic.

D. Yes; it can be rewritten in the form y = ax2 + bx + c.

There is no b, so you would skip over it

3y = -7x + 8

isolate the y (divide 3 from both sides)

(3y)/3 = (-7x + 8)/3

y = (-7x + 8)/3 would be your answer

D. Yes; it can be rewritten in the form y = ax2 + bx + c. (is actual answer)

hope this helps

Leigh has a piece of rope that is 6 2/3 feet long. How do you write 6 2/3 as a fraction greater than 1
aleksley [76]
20/3 - Take the 6 2/3, multiply the 6 and the 3 (6 x 3 = 18), then add the 2 (18 + 2 = 20). Put that number over the original 3 and you've got yourself a mixed number.

Mai biked 5 1/4 miles today, and Noah biked 2 1/2 miles. How many times the length of Noah’s bike ride was Mai’s bike ride?
OlgaM077 [116]

Answer:

The length of Mai's bike ride was 2.1 times the length of Noah's ride.

Step-by-step explanation:

Mai biked 5 1/4 miles today

So he biked, in miles:

5 + \frac{1}{4} = \frac{5*4 + 1}{4} = \frac{20+1}{4} = \frac{21}{4}

Noah biked 2 1/2 miles.

So, in miles, he biked:

2 + \frac{1}{2} = \frac{2*2 + 1}{2} = \frac{4+1}{2} = \frac{5}{2}

How many times the length of Noah’s bike ride was Mai’s bike ride?

We divide the Mai distance by Noah's distance. In a division of fractions, we multiply the numerator by the inverse of the denominator. So

\frac{\frac{21}{4}}{\frac{5}{2}} = \frac{21}{4} \times {2}{5} = \frac{21*1}{2*5} = \frac{21}{10} = 2.1

The length of Mai's bike ride was 2.1 times the length of Noah's ride.
