Answer:
(k-x)(x+y)
Step-by-step explanation:
x×(k-x)+y×(k-x)
=(k-x)(x+y)
Answer: No Solution
║ 3x + 2y = 7 ==> Multiply by 2
║ 6x + 4y = 14
║ 6x + 4y = 14
║ 6x + 4y = 14
There is no solution.
Answer:
The third answer (C).
Step-by-step explanation:
This graph starts at 10. So it needs the +10 at the end.
Also the slope is -1/2 because the graph goes down one, right two. Rise/run.
Answer:
Step-by-step explanation:
We have to find the inverse of the function g(x) where .
If we have a function y = f(x), then expressing the value of x in terms of y i.e. x = F(y) is called the inverse of the function y = f(x).
So, inverse of y = f(x) is x = F(y).{Where f and F are two different functions}
Now, we have

So, (Answer)
Answer:
SAS Congruence Postulate
Step-by-step explanation:
In ΔABC and ΔDCE
AC=CE [given]→Side
∠ACB=∠DCE [vertically opposite angles]→Angle
BC=DC [given]→Side
∴ ΔABC ≅ ΔDCE [SAS congruence postulate]
SAS congruence postulate tells that if two sides and the included angle of one triangle are congruent to two sides and the included angle of other triangle, then the two triangles are congruent.
This is SAS. Notice you have 2 sides that are equal to each other and the vertical angle between them. Since the angle is between the 2 sides then the postulate that works is SAS.
