Answer:
Side TV = 16
Step-by-step explanation:
WX is half the value of TV
to solve we have to set up an equation
21-5x=10x-2
because side WX is only have of side TV we have to multiple its side by 2 so now we have
21-5x=20x-4
step 1 add 4 to each side
25-5x=20x
step 2 add 5x to each side
25=25x
step 3 divide each side by 25
x=1
then we plug in x as 1 for side TV and get
21-5 which is equal to 16
X=10, AE is 46 because its twice the size of BF, set 5x-4 equal to 46 (5x-4=46) and solve
Answer:
Exponential growth of 93%
Step-by-step explanation:
f(x) = 1.93^x = (1 + 0.93)^x
Answer:
Step-by-step explanation:
Distance formula:
![\sqrt{(X_2-X_1)^2+(Y_2-Y_1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28X_2-X_1%29%5E2%2B%28Y_2-Y_1%29%5E2%7D)
Distance for AB
![\sqrt{(4-2)^2+(1-(-5))^2}=\sqrt{4+36}=\sqrt{40}\\](https://tex.z-dn.net/?f=%5Csqrt%7B%284-2%29%5E2%2B%281-%28-5%29%29%5E2%7D%3D%5Csqrt%7B4%2B36%7D%3D%5Csqrt%7B40%7D%5C%5C)
Distance for AC
![\sqrt{(8-2)^2+(-3-(-5))^2}=\sqrt{36+4}=\sqrt{40}](https://tex.z-dn.net/?f=%5Csqrt%7B%288-2%29%5E2%2B%28-3-%28-5%29%29%5E2%7D%3D%5Csqrt%7B36%2B4%7D%3D%5Csqrt%7B40%7D)
2.
same formula solve when positive
![5=\sqrt{(6-3)^2+(y-2)^2}\\25=9+(y-2)^2\\16=(y-2)^2\\4=y-2\\6=y](https://tex.z-dn.net/?f=5%3D%5Csqrt%7B%286-3%29%5E2%2B%28y-2%29%5E2%7D%5C%5C25%3D9%2B%28y-2%29%5E2%5C%5C16%3D%28y-2%29%5E2%5C%5C4%3Dy-2%5C%5C6%3Dy)
Now when it's negative
![5=\sqrt{(6-3)^2+(y-2)^2}\\25=9+(y-2)^2\\16=(y-2)^2\\-4=y-2\\y=-2](https://tex.z-dn.net/?f=5%3D%5Csqrt%7B%286-3%29%5E2%2B%28y-2%29%5E2%7D%5C%5C25%3D9%2B%28y-2%29%5E2%5C%5C16%3D%28y-2%29%5E2%5C%5C-4%3Dy-2%5C%5Cy%3D-2)
so y can equal 6 or -2
