Answer: B. 8x+3y=5
-8x - 4y= -6
Step-by-step explanation:
The given system of equations is expressed as
8x + 3y =5 - - - - - - - - -1
4x + 2y =3 - - - - - - - - - - 2
We would eliminate x by multiplying equation 1 by 4 and equation 2 by 8. It becomes
32x + 12y =20
32x + 16y = 24
Subtracting, it becomes
- 4y = - 4
y = - 4/ - 4
y = 1
Substituting y = 1 into equation 1. It becomes
8x + 3 × 1 =5
8x + 3 = 5 - 3 = 2
x = 2/8 = 1/4
Substituting x = 1/4 and y = 1 into the given options, it becomes
A. 8 × 1/4 + 3 × 1=5
2 + 3 = 5
- 8 × 1/4 +4 × 1 = 2
B. 8x+3y=5
-8x - 4y= -6
- 8 × 1/4 - 4 × 1 = -6
Therefore, the system of of equations that has the same solution as the given equation is
B. 8x+3y=5
-8x - 4y= -6

Answer:
Part (One): A) The triangles are congruent/
Part (Two): D) the slop of the line is not equal to a/b or c/d
Step-by-step explanation:
1. The triangles cannot be congruent since there is only one 90 degree angle. for each of them.
2. The slope for every point would always be the same. The only possible answer to be that the slope of the line isn't equal to a/b nor c/d. It wouldn't make sense if the slope of the line was equal to a/b or c/d was true and if the slope of the line was equal to a/b or c/d at the same time.
Answer:well we need to know how mmch tim has so like
x?+2 is amy
x?+2*5 is sarah
Step-by-step explanation:
Assumptions: Based on your question is seems like you are trying to find the distance the cue ball was initially at from the pocket from the minimum angle being 90 degrees.
Answer: In this case we can assume the minimum angle that the eight ball had after the collision was 90 degrees and therefore we can use Pythagoras Theorem (only can be used for right triangles). This gives us the length of both sides of that triangle we have constructed which are 8 in. and 6 in.. In the context of our drawing we want to find the hypotenuse of the triangle which would be the initial distance the eight ball was from the pocket (once again being at the most minimum possible angle). a^2=b^2+c^2 . a=sqrt(b^2+c^2) .
Plug in for b and c and you should get that it was greater than 10 in.
