Answer:
the 3rd one
Step-by-step explanation:
i graphed it mentally and found out the slope was 2 and the y intercept is 1
Remember you can do anything to an equation as long as you do it to both sides (except divide by 0)
add like terms
3x-x=3x-1x=2x
so
3x-x+2=12
2x+2=12
subtract 2 from both sides
2x=10
divide both sides by 2
x=5
Answer:
The Triangle Is A Right Triangle Because 5^2 + 12^2 = 13^2.
Step-by-step explanation:
5^2 = 25. 12^2 = 144. With the Pythagorean theorem, (a^2 + b^2 = c^2), 5 is a, 12 is b, and 13 is c.
25 + 144 = 169.
13 ^ 2 = 169.
Since a^2 + b^2 = c^2 is true, the triangle is a right triangle.
Accuracy is basically how close the given amount is to the actual amount
