Which equation results from adding the equations in this system? 11 x minus 3 y = negative 17. Negative 4 x + 3 y = negative 18.
1 answer:
Answer:
7x = - 35
Step-by-step explanation:
Equation 1 :
11x - 3y = - 17
Equation 2 :
-4x + 3y = - 18
Equation 1 + 2
11x - 3y = - 17
-4x + 3y = - 18
_____________
11x - 4x - 3y + 3y = - 17 + (-18)
7x = - 35

Y = (2/3).x - 6. If y=0, then 0= (2/3).x - 6. Solve for x:
2x/3 - 6 = 0
Same denominator:
(2x - 18)/3 = 0
2x - 18 = 0
2x = 18 and x = 9 (x-coordinate)

Answer:
8√2
Step-by-step explanation:
4√2 + 7√2 - 3√2 = (√2)(4 + 7 - 3) = 8√2
Recognize that √2 is a common factor and simply add its coefficients.
