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

Mathematics
1 answer:
raketka [301]2 years ago
3 0

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

Answer:

3x+2y+4=27

Step-by-step explanation:

Let

x ----> represents the number of 3-point field goals

y ----> represents the number of 2-point field goals

we know that

The number of 3-point field goals multiplied by 3 plus the number of 2-point field goals multiplied by 2 plus the number of free throws (4) multiplied by 1, must be equal to 27 points

so

The equation that represent this situation is

3x+2y+4=27

A car is traveling at 60 mph and is tailgating another car at distance of only 30 ft. If the reaction time of the tailgater is 0
Sveta_85 [38]

Answer:

44 ft

Step-by-step explanation:

We are given that;

Speed; v = 60 mph

Reaction time;t = 0.5 s

Now, we know that;

Distance = speed x time

Since time is in seconds, let's convert speed to mph to ft/s

From conversion,

1 mph = 1.46667 ft/s

So, 60 mph would give;

60 × 1.46667 ≈ 88 ft/s

Thus, distance his car travels during his reaction time is;

Distance = 88 × 0.5 = 44 ft
