M = Mo - 20 * Weeks = 300 - 20 * 6 = 180 $
If they intersect they have the same x and y values so we can say y=y which can be expressed as:
-7x/8+1/4=-3x/4+1/2 make all terms have a common denominator of 8
-7x/8+2/8=-6x/8+4/8 now multiply all terms by 8
-7x+2=-6x+4 add 6x to both sides
-x+2=4 subtract 2 from both sides
-x=2 divide both sides by -1
x=-2, now we solve for y using either original equation...
y=-3(-2)/4+1/2
y=6/4+1/2
y=6/4+2/4
y=8/4
y=2 so the lines intersect at the point:
(-2, 2)
Answer:
The x-intercepts of the quadratic function are -7 and 5.
Step-by-step explanation:
The given function is

Equate f(x)=0, to find the x-intercepts of the function.






Therefore the x-intercepts of the quadratic function are -7 and 5.
Presumably, whatever is drawn from Urn I is independent of what is drawn from Urn II. This means

We have


so the probability of drawing red balls from both urns is 
ANSWER

EXPLANATION
The sum of the interior angles of a triangle is 180°
We can rewrite this as:

The sum of interior angles of a quadrilateral is 360°
We can also rewrite this as:
In general an n-sided polygon has
the sum of the interior angles given by the formula:
