6x=-12
x=-2
2(-2)-3y=-19
-3y=-15
y=5
Intersection Point: (-2,5)
Answer:
11. x = 8
12. x = 15
13. x = 9
Step-by-step explanation:
This statement of the applicable relation is perhaps a little different than the one(s) you may have seen: From the point where the segments meet, the product of the length of segment to one side of the circle and the length of segment to the other side of the circle is the same for both segments. When the segment is tangent to the circle, those two circle intersection points are the same point.
This rule is applicable for all of these problems. Once the relation is written, the equation can be divided by the coefficient of x to find the value of x.

<h3>11.</h3>
12·4 = 6x
x = 48/6 = 8
__
<h3>12.</h3>
x·x = 9·(16+9)
x = √(9·25) = 15 . . . . take the square root
__
<h3>13.</h3>
x·16 = 8·(8+10)
x = 144/16 = 9
Given:
The volume of the rectangular prism is

,
the height is h=(b+3)
1. The volume of a rectangular prism is (base area)*height
also, notice that the volume is a third degree polynomial, the height is a 1st degree polynomial, so the base area must be a 2nd degree polynomial, whose coefficients we don't know yet.
Let this quadratic polynomial be
2

notice that

is the product of the largest 2 terms:

and b, so m must be 1
also, notice that 12 is the product of the constants, k and 3
so k*3=12, this means k=4
3
we write the above equality again:


=

4
now compare the coefficient with the left side:

8=n+3
n=5
substituting n=5:
the base area is

Answer:

if x=10 y=-2 and z=-5 then...

we solve this to get...
<em>65</em>
therefore the answer to your question would be 65
hope this helped-have a good day bro cya)
I just solved it and I'm pretty sure its only one solution, I took the bottom equation multiplied it by -3 then i canceled out the equations and got 9. So that would make it C.
