2/3
6x = 4
x = 2/3
The scale factor can be determined by using similar sides
Capetown as it has higher temp.
Answer:
y = 2x - 3
Step-by-step explanation:
Start by writing out the given equation.
-2x + y = -3
The goal is to isolate the variable y.
For this equation, all you need to do is add 2x to each side.
-2x + y + 2x = -3 + 2x
Therefore, the answer is y = 2x -3.
I don't know if you are are familiar with the equation y = mx + b, but here's a little refresher. m is the slope, or in this case 2. b is the y-intercept, or in this case -3.
The equation y = mx + b is slope intercept form, so if you know this, you should be able to write any equation in slope intercept form.
Hope this helps!
Answer:
D (42,-56)
Step-by-step explanation:
Scale factor means you multiply, so you multiply (6,-8) by 7.
6 x 7 is 42 and 7 x -8 is -56. So your answer is D (42,-56).
So hmm check the picture below
the radius "r" is half the diameter, meaning, the diameter is 2r long
now, if the height "h" is twice "d" or 2d, then that means h = 2(2r)
thus
![\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}\qquad \begin{cases} h=height\\ r=radius\\ ------\\ h=2(2r) \end{cases}\implies V=\cfrac{\pi r^2[2(2r)]}{3} \\\\\\ V=\cfrac{4\pi r^3}{3}](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Bvolume%20of%20a%20cone%7D%5C%5C%5C%5C%0AV%3D%5Ccfrac%7B%5Cpi%20r%5E2%20h%7D%7B3%7D%5Cqquad%20%0A%5Cbegin%7Bcases%7D%0Ah%3Dheight%5C%5C%0Ar%3Dradius%5C%5C%0A------%5C%5C%0Ah%3D2%282r%29%0A%5Cend%7Bcases%7D%5Cimplies%20V%3D%5Ccfrac%7B%5Cpi%20r%5E2%5B2%282r%29%5D%7D%7B3%7D%0A%5C%5C%5C%5C%5C%5C%0AV%3D%5Ccfrac%7B4%5Cpi%20r%5E3%7D%7B3%7D)
