A. 6x - 8 = 4; 6x = 12; x = 2
b. 6x - 8 = 1 ; 6x =9; x = 3/2
Answer:
Step-by-step explanation:
Equation of unit circle is:
Plug
in above equation.
Since, point P is in the fourth quadrant.
Therefore, x - coordinate should be positive.

Answer:
(B) 18.
Step-by-step explanation:
We are asked to find the perimeter of a quadrilateral with vertices at (-1, 4), (7,4), (7,5), and (-1. 5).
First of all, we will draw vertices of quadrilateral on coordinate plane and connect the vertices as shown in the attached photo.
We can see that our quadrilateral is a parallelogram, whose parallel sides are equal.



Therefore, the perimeter of the given quadrilateral is 18 units.
I think the answer is mean. (The average) it could also be “mean average deviation” but I’m not sure what that one means...
In this question, <span>Karen measures the garden width result in 44.25 m while it's actual width is 45.5m. Then the amount of error that the Karen did would be: 45.5m-44.25m= 1.25m
The percent error would be:
</span>percent error = amount of error/ actual measurement
percent error = 1.25m/ 45.5m *100%=2.7%
