Answer:
( , - )
Step-by-step explanation:
8x + 4y = 7 → (1)
6x - 8y = 41 → (2)
multiplying (1) by 2 and adding to (2) will eliminate y
16x + 8y = 14 → (3)
add (2) and (3) term by term to eliminate y
22x + 0 = 55
22x = 55 ( divide both sides by 22 )
x = =
substitute this value into either of the 2 equations and solve for y
substituting into (1)
8( ) + 4y = 7
20 + 4y = 7 ( subtract 20 from both sides )
4y = - 13 ( divide both sides by 4 )
y = -
solution is ( , - )
Hm i think 3.700 and 3.70
Answer:
B. 9
Step-by-step explanation:
When the line runs( x variation) by 1 , it rises (y variation) by 9
And since unit rate is calculated by Rise/Run, the unit rate is 9/1 or 9
