Answer:
y = -1/2x + 13/2
Step-by-step explanation:
The slope of a line that is perpendicular to a line will be a negative reciprocal. When you rewrite 2x-7=8 into slope-intercept form, you get y=2x-8. The negative reciprocal of the slope 2x is -1/2x. There is only one option with this slope. If you're still not sure then you can use a graphing calculator to check this. An online one would be desmos
Answer:
6.3 units (nearest tenth)
Step-by-step explanation:

Using the formula above,
distance between (-8, 6) and (-6, 0)
![= \sqrt{ {[ - 8 - ( - 6)]}^{2} + {(6 - 0)}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%20%7B%5B%20-%208%20-%20%28%20-%206%29%5D%7D%5E%7B2%7D%20%20%2B%20%20%7B%286%20-%200%29%7D%5E%7B2%7D%20%7D%20)




= 6.3 units (nearest tenth)
Answer:
My age is 12 years.
Step-by-step explanation:
Given:
Sister's age = 10 years
Let my age be x.
Now according to question;
my brother's age is 1/3 of my age
So brother's age = 
Also according to question;
my sister is 6 years older than my brother;
Sister's age = 
Also given Sister's age = 10 years
hence equation to find my age will be expressed as below;

Brothers age = 
Hence my age is 12 years.
