Answer:
(3, 2)
Step-by-step explanation:
Given the 2 equations
y = 2x - 4 → (1)
3x + y = 11 → (2)
Substitute y = 2x - 4 into (2)
3x + 2x - 4 = 11
5x - 4 = 11 ( add 4 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
Substitute x = 3 into (1) for corresponding value of y
y = (2 × 3) - 4 = 6 - 4 = 2
Solution is (3, 2)
Answer:
14.36446281 is the answer, you probably have to round
<span>7/8 - 1/4 = 7/8 - 2/8 = 5/8</span>
Use the quadratic formula to solve. the answer is the third one down
x= -sqrt10 - 4 and sqrt10 - 4
or in their notation above x= -4+/-10--sqrt
