Answer:
20
Step-by-step explanation:
16=1 2/10R + -8
16+8= 12/10R
24=12/10R
R=20
X=120
This is the answer because 120-21=99
Answer:
A
Step-by-step explanation:
it goes down by 9 and left by 3
Answer:
![\sqrt{10}](https://tex.z-dn.net/?f=%5Csqrt%7B10%7D)
Step-by-step explanation:
The horizontal distance from points (5,-18) and (8,-17) is 3 because it is 3 units from 5 to 8. The vertical distance is 1 since it is one unit from -18 to -17. Now we can use the equation
where a=3 and b=1 and c is the distance that you are looking for:
![a^{2} +b^{2} =c^{2}\\3^{2} +1^{2} =c^{2}\\9+1=c^{2}\\10=c^{2}\\\sqrt{10}=c](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D%5C%5C3%5E%7B2%7D%20%2B1%5E%7B2%7D%20%3Dc%5E%7B2%7D%5C%5C9%2B1%3Dc%5E%7B2%7D%5C%5C10%3Dc%5E%7B2%7D%5C%5C%5Csqrt%7B10%7D%3Dc)

with that template in mind, let's see,
![\bf f(x)=|x| \implies \begin{array}{lllccll} f(x)=&1|&1x&+0|&+0\\ &\uparrow &\uparrow &\uparrow &\uparrow \\ &A&B&C&D \end{array}](https://tex.z-dn.net/?f=%5Cbf%20f%28x%29%3D%7Cx%7C%20%5Cimplies%20%5Cbegin%7Barray%7D%7Blllccll%7D%0Af%28x%29%3D%261%7C%261x%26%2B0%7C%26%2B0%5C%5C%0A%26%5Cuparrow%20%26%5Cuparrow%20%26%5Cuparrow%20%26%5Cuparrow%20%5C%5C%0A%26A%26B%26C%26D%0A%5Cend%7Barray%7D)
so, to shift it to the right by 2 units, simply set C = 2.
to stretch it by 2, set A = 1/2.
the smaller A is, the wider it opens, the larger it is, the more it shrinks.
