Answer:
(x, y) = (-6, -4)
Step-by-step explanation:
The solution can be found quickly using a graphing calculator. It is the point of intersection of the two lines.
_____
If you like, you can solve the system algebraically. The second equation can be rewritten to give ...
y = x +2
Substituting this into the first equation gives ...
5/3x -2(x +2) = -2
-1/3x -4 = -2
Adding 4 and multiplying by -3 gives ...
x = -3(-2+4) = -6
Then our equation for y tells us ...
y = -6 +2 = -4
The solution is (x, y) = (-6, -4).
Step-by-step explanation:
You can't use quadratic formula in this
The answer should be 50% because there is two points on each side of the whisker plot making it 50/50
You didn't supply a list. The so-called rigid transformations of translation, rotation and reflection create congruent triangles.
Generally it's dilation by a factor about a point is preserves similarity but not congruency. Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.
Rewrite the equation as;
-0.3(7n - 31.2) = 0.456
Divide each term by 0.3 and simplify;
-7n + 31.2 = 1.52
Move all terms not containing n to the right side of the equation;
-7n = -29.68
Divide each term by -7 and simplify;
<u>n = 4.24 </u>
