Answer:
Solution to system is
x = 6 and y= 4
S.set={6,4}
Step-by-step explanation:
The given equations are
x + 3y = 18 ................(i)
x + 2y=14 .................(ii)
Subtracting both equation
(x+3y)-(x+2y)=18-14
x+3y-x-2y = 4
y = 4
put the value of y in equation (i)
the equation becomes
x + 3(4) = 18
x + 12 = 18
subtracting 12 from both sides
x + 12 -12 = 18-12
x =6
Solution to system is
x = 6 and y= 4
S.set={6,4}
Answer:
B) rotation 180 degrees about the origin
Step-by-step explanation:
Also, what do the words underneath D) say? I think the answer could also be a reflection across y = x.

Step-by-step explanation:
Given:
Tina cut 3 wood boards each into 4 equal pieces.
She used 3 of the pieces for a craft.
Question asked:
What fraction of the boards does she have left ?
Write this fraction as a mixed number.
Solution:
<em><u>As she cuts 3 wood board each into 4 equal pieces :-</u></em>
Total number of equal pieces = 
Pieces of wood used = 3
Remaining pieces = 12 - 3 = 9
<h3>
<u><em>Now, we will write these 9 pieces in terms of number of wood boards</em></u>.</h3>
<u>By unitary method:</u>
4 pieces constitute = 1 wood board
1 piece constitute = 
9 pieces constitute = 
<em>Now, convert it into mixed fraction:</em>

Therefore, fraction of the boards she have left is
.
Answer:
A) not congruent. You only know one side and one angle to be congruent.
Step-by-step explanation:
The inverse of the function f(x) = 2x - 10 is f-1(x) would be x/2 + 5.
Lets try to solve it,
We will be using the inverse function to solve this.
f(x) =
Replace f(x) with y.

Interchange x and y

Solve for y

Replace y with f-1(x).

Thus, the inverse of the function f(x) = 2x - 10 is f-1(x) = x/2 + 5
