Answer:
Given the system of equation:
......[1]
......[2]
we can rewrite equation [2] as;
......[3]
Substitute equation [3] into [1] to eliminate x, and solve for y;
Using distributive property: 
Combine like terms;
16 - 8y = -4
Add 4 to both sides we have;
20 - 8y = 0
Add 8y to both sides we have;
20 = 8y
Divide 8 to both sides we have;
Substitute the y-value in [3] we have;
x = 8 - 5 = 3
Therefore, the expression should be substituted into the first equation is, and also the value of x = 3 and y = 2.5
1, 3, 5, 7, 8, 11, 13, 15 is the answer.
Answer:
keep calm and believe in yourself
(A) Domain of given function is {x | x = –6, –1, 0, 3} as domain means all the value in x sets.
(B) The 2nd graph(3rd figure) is representing the Function as there is an unique value for every x values.But in the other figure there is more than one value for one value of x. (Answer)
Answer:
Option D is correct.
SAS Congruence Postulates
Step-by-step explanation:
In Δ QRS and Δ TRS
[Side] [Given]
[Common Side] [Given]
[Angle]
SAS(Side- Angle -Side) postulates states states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
Then, by SAS postulates
