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}
Step 1) Distribute everything in parentheses
<em>4</em><em>5</em><em>m</em><em>+</em><em>9</em><em>0</em><em>0</em><em> </em><em>=</em><em> </em><em>9</em><em>0</em><em>m</em>
Step 2) Subtract <em>4</em><em>5</em><em>m</em><em> </em>from both sides
<em>9</em><em>0</em><em>0</em><em> </em><em>=</em><em> </em><em>4</em><em>5</em><em>m</em>
Step 3) Divide

A graph shows x-3 to be a factor, selection B.
The factorization would be (7x +3)(x -3).
Answer:
3a - b = 1
Step-by-step explanation:
a = (2-3)
b = (1-5)
Substitute the values of a and b to the 3a-b.
3(2-3) - (1-5)
6-9 - (-4)
6 - 9 + 4
-3 + 4
= 1
Therefore, 1 is the answer.
