Answer:
(- 1, 1 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 4 → (1)
y = x + 2 → (2)
Substitute y = 3x + 4 into (2)
3x + 4 = x + 2 ( subtract x from both sides )
2x + 4 = 2 ( subtract 4 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting x = - 1 into (2)
y = - 1 + 2 = 1
Solution is (- 1, 1 )
Answer: 8.5
Step-by-step explanation:
I just took the quiz last week.
40 because if you multiply 2 by 100 it is 200 then divide that by 5 and you get 40
1.49 × 10^8
*just move the decimal point 8 places to the right.
149,000,000
hope this helps :)
