The slope intercept form of a line is y = mx + b
where m = slope and b = y-intercept
The given equation becomes
3x - 5y = 10
-5y = -3x + 10
y = (-3x + 10)/-5
y = (3/5)x - 2
That is the answer.
Answer:
option 4
Step-by-step explanation:
f(x) = 5x + 40
f(x = - 5) = 5 ( - 5) + 40
= - 25 + 40
= 15
it the temperature is -2 and rises by 15 you do -2+ 15 to get 13
<u>the answer would be 3 x 3 x 7</u>
The required equation of the surface area of the cylinder is 
<u>Solution:</u>
Let "r" be the radius of cylinder and "h" be the height.
Formula for surface area is:

where
is surface of two bases of cylinder and
is surface of mantle.
From the given, the height of the gift box is three times the radius, i.e 
On substituting the given values in the formula we get,
![S = 2\times\pi[(3x+4)^2 + (9x+12)\times(3x+4)]](https://tex.z-dn.net/?f=S%20%3D%202%5Ctimes%5Cpi%5B%283x%2B4%29%5E2%20%2B%20%289x%2B12%29%5Ctimes%283x%2B4%29%5D)
