Answer:
Do you mean which equation should the 5x+10=15 be multiplied to?
it would be -2
Step-by-step explanation:
This is because 5 times -2 is -10
and so when you add the (now) x value of the first equation to the x value of the second equation, it gets 0
which makes it eliminated!
-10x+10x=0
Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
Answer:
Step-by-step explanation:
looking at the graph,
when x = 3, y = -10
-10 = 2(3)^2 + 3b + 8
-10 = 18 + 3b + 8
-10 = 26 + 3b
3b = -36
b = -36/3
b = -12
Answer:
11/3
<em>Alternative Form: </em>3 2/3, 3.6
Step-by-step explanation:
44/12
Dive the numerator and denominator by 4
44/4 / 12/4
11/ 12/4
11/3
<em>x equals 22</em>

The Segment Postulate states the following:
<em>Given two end points A and B, a third point C lines on the segment AB if and only if the distances between the points satisfy the equation:</em>
![\overline{AB}=\overline{AC}+\overline{CB}](https://tex.z-dn.net/?f=%5Coverline%7BAB%7D%3D%5Coverline%7BAC%7D%2B%5Coverline%7BCB%7D)
____________________________________________
From the figure:
![\overline{AC}=8+x \\ \\ \overline{CB}=10 \\ \\ \overline{AB}=40](https://tex.z-dn.net/?f=%5Coverline%7BAC%7D%3D8%2Bx%20%5C%5C%20%5C%5C%20%5Coverline%7BCB%7D%3D10%20%5C%5C%20%5C%5C%20%5Coverline%7BAB%7D%3D40)
Our goal is to find x:
![\overline{AB}=\overline{AC}+\overline{CB} \\ \\ Substituting \ values: \\ \\ 40=(8+x)+10 \\ \\ 18+x=40 \\ \\ Subtracting \ 18 \ from \ both \ sides: \\ \\ 18-18+x=40-18 \\ \\ \boxed{x=22}](https://tex.z-dn.net/?f=%5Coverline%7BAB%7D%3D%5Coverline%7BAC%7D%2B%5Coverline%7BCB%7D%20%5C%5C%20%5C%5C%20Substituting%20%5C%20values%3A%20%5C%5C%20%5C%5C%2040%3D%288%2Bx%29%2B10%20%5C%5C%20%5C%5C%2018%2Bx%3D40%20%5C%5C%20%5C%5C%20Subtracting%20%5C%2018%20%5C%20from%20%5C%20both%20%5C%20sides%3A%20%5C%5C%20%5C%5C%2018-18%2Bx%3D40-18%20%5C%5C%20%5C%5C%20%5Cboxed%7Bx%3D22%7D)
