<span>If the function is already in the form of y = ax²+bx+c, then all you have to do is look at "a". If it "a" is positive, then it will open up(look like a U) if "a" is negative, then it will open down(look like an upside down U)</span>
Answer:
The answer is 16
Step-by-step explanation:
It's 16 cause both side are the same.
Answer:
y=4/3x+4
Step-by-step explanation:
y-y1=m(x-x1)
y-(-8)=4/3(x-(-9))
y+8=4/3(x+9)
y=4/3x+36/3-8
y=4/3x+12-8
y=4/3x+4
Answer: 32 2/19°F
Step-by-step explanation:
Since the temperature was 52° and dropped to 38°, the difference will be:
= 52° - 38°
= 14°
Therefore, 14° was dropped in 4¾ hours. Therefore, the temperature dropped pee hour will be:
= 14/4¾
= 14 / 19/4
= 14 × 4/19
= 56/19
= 2 18/19° per hour.
In 2 hours, the temperature dropped will be:
= 2 18/19° × 2
= 5 17/19°
With the above explanation, the temperature after 2 hours will then be:
= 38° - 5 17/19°
= 32 2/19°F
The temperature will be 32 2/19°F.
7,040 Yards because there is 1760 yards in a mile.
1760 x 4 = 7,040
