Okay so you are correct with the gradient of the perpendicular line it is -5/2 however the equation is not y= -5/2 -1 because it is a new Line and has a new y-intercept therefore its Y=-5/2 + C but you have corrected that when doing the formula and have got the right answer
10000x8%= $800 anually
anually=yearly
800x18=14400
Answer: ![186^{\circ}F](https://tex.z-dn.net/?f=186%5E%7B%5Ccirc%7DF)
Step-by-step explanation:
Given : In the Sahara Desert one day it was 136°F.
In the Gobi Desert a temperature of -50°F was recorded.
Clearly , 136°F> -50°F
Then, the difference between these two temperatures will be :-
![136^{\circ}F-(-50)^{\circ}F\\\\=(136+50)^{\circ}F\ \ [\because \text{Product two neagtive sign is positive]}\\\\=186^{\circ}F](https://tex.z-dn.net/?f=136%5E%7B%5Ccirc%7DF-%28-50%29%5E%7B%5Ccirc%7DF%5C%5C%5C%5C%3D%28136%2B50%29%5E%7B%5Ccirc%7DF%5C%20%5C%20%5B%5Cbecause%20%5Ctext%7BProduct%20two%20neagtive%20sign%20is%20positive%5D%7D%5C%5C%5C%5C%3D186%5E%7B%5Ccirc%7DF)
Hence, the difference between these two temperatures = ![186^{\circ}F](https://tex.z-dn.net/?f=186%5E%7B%5Ccirc%7DF)
Answer:
x = 49
Step-by-step explanation:
Given
=
( cross- multiply )
5(x - 16) = 3(x + 6) ← distribute parenthesis on both sides
5x - 80 = 3x + 18 ( subtract 3x from both sides )
2x - 80 = 18 ( add 80 to both sides )
2x = 98 ( divide both sides by 2 )
x = 49
