Answer:
(x, y) = (-4, -15)
Step-by-step explanation:
Perhaps you want the solution to ...
y = 3/4x -12
y = -4x -31
Equating the two expressions for y gives ...
3/4x -12 = -4x -31
3/4x = -4x -19 . . . . . add 12
3x = -16x -76 . . . . . multiply by 4
19x = -76 . . . . . . . . . add 16x
x = -76/19 = -4 . . . . divide by 19
y = (3/4)(-4) -12 = -15 . . . . use the first equation to find y
The solution to this system of equations is ...
(x, y) = (-4, -15)
First off, actually including the diagram is required if you intend on getting an answer. Thankfully, someone else has posed this question on another site and actually included the diagram. I will first describe the diagram, and then solve the problem.
And the good news is ....
The triangle in the diagram is impossible.
The diagram I found has Josh, Devon, and Marco standing creating an isosceles triangle with Josh and Devon forming the base. And with the given measurements, the illustrated triangle is impossible since in order for form an isosceles triangle with a base of 16 feet (the distance between Josh and Devon), each leg of the triangle would have to be at least 8 feet long and the specified 5 1/3 feet is way too short. So the actual triangle created by Josh, Devon, and Marco can't be an isosceles triangle. But the triangle created by Marco and points A and B has to be an isosceles triangle since the distance from Marco to both points A and B is 4 feet. Therefore we can prove that the two triangles are NOT similar. And therefore using the constant ratio between similar sides of the triangles can not apply.
Answer: D
Step-by-step explanation:
Given that Svana wants to solve the equation 1/2x - 1.0675 = 3x - 4145.
This equation is a system of equations which can be solved by using simultaneous equation methods.
But if she uses a graphing program to graph the equations y = 1/2x - 1.0675 and y = 3x - 4.145
The solution of 1/2x - 1.0675 = 3x - 4.145. Will be the point of intersection of the two equation.
Trace the point of intersection to the x - axis and also to the y - axis.
The solution to the system of equations is ( 1.231, - 0.452 )
