Answer:
sarah is incorrect.
Step-by-step explanation:
She is incorrect because a fraction of a fraction is never going to lead to a whole number. For example, 1/3 times 1/3, you will get 1/6. The fraction will always get smaller, not bigger.
Hi, thank you for posting your question here in Brainly.
Celsius and Fahrenheit are units of temperature, and they can be converted using a formula.
F = C*1.8 + 32
For example, 30°C is
F= 30*1.8 + 32
F = 86°F
Or an easier way to remember without memorizing the formula is by remembering the normal boiling point of water which is 100°C = 212°F.
Answer:
X^2 y
Step-by-step explanation:
So now you can make this x^2 y because the ^3 cancels it out
Answer:
![\fbox{\begin{minipage}{16em}Option D: y = (4/7)x + 8 is correct\end{minipage}}](https://tex.z-dn.net/?f=%5Cfbox%7B%5Cbegin%7Bminipage%7D%7B16em%7DOption%20D%3A%20y%20%3D%20%284%2F7%29x%20%2B%208%20is%20correct%5Cend%7Bminipage%7D%7D)
Step-by-step explanation:
(1) A typical form of equation of a line is:
![y = Mx + b](https://tex.z-dn.net/?f=y%20%3D%20Mx%20%2B%20b)
with,
is slope and
is y-intercept.
(2) Another straight line has equation in form of:
![y = Nx + c](https://tex.z-dn.net/?f=y%20%3D%20Nx%20%2B%20c)
with
is slope and
is y-intercept
(3) If these two lines are perpendicular, according to the property of two perpendicular lines on the two-dimensional plane, we have:
x
= -1
(4) Transform the given equation of original line into typical form:
![7x + 4y = -24\\](https://tex.z-dn.net/?f=7x%20%2B%204y%20%3D%20-24%5C%5C)
<=> ![4y = -7x - 24](https://tex.z-dn.net/?f=4y%20%3D%20-7x%20-%2024)
<=> ![y = (\frac{-7}{4})x - \frac{24}{4}](https://tex.z-dn.net/?f=y%20%3D%20%28%5Cfrac%7B-7%7D%7B4%7D%29x%20%20-%20%5Cfrac%7B24%7D%7B4%7D)
<=> ![y = (\frac{-7}{4})x - 6](https://tex.z-dn.net/?f=y%20%3D%20%28%5Cfrac%7B-7%7D%7B4%7D%29x%20-%206)
=> ![M = \frac{-7}{4}](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%7B-7%7D%7B4%7D)
=> ![N = \frac{-1}{M} = \frac{-1}{\frac{-7}{4} } = \frac{-4}{-7} = \frac{4}{7}](https://tex.z-dn.net/?f=N%20%3D%20%5Cfrac%7B-1%7D%7BM%7D%20%20%3D%20%5Cfrac%7B-1%7D%7B%5Cfrac%7B-7%7D%7B4%7D%20%7D%20%3D%20%5Cfrac%7B-4%7D%7B-7%7D%20%3D%20%5Cfrac%7B4%7D%7B7%7D)
=> Option D:
is correct (Slope =
)
Hope this helps!

f(-4) = 3(-4)^2 - 2(-4)
f(-4) = 3(16) + 8
f(-4) = 48 + 8
f(-4) = 56
I think the answer is 56 :)
