Firstly, solve the inequality for y using subtraction:
y > -6 - 4x
Then plug in the x and y values from the answer until the inequality proves true:
-12 > -6 -4(1)
-12 > -10 (false)
Then the next choice:
-9 > -6 - 4(0)
-9 > -6 (false)
Next choice:
-1 > -6 -4(-1)
-1 > -6 + 4
-1 > -2 (true)
Therefore, C is the correct answer. Hope this helps and let me know if you need more help!
Answer:
A
Step-by-step explanation:
since both equations express y in terms of x we can equate the right sides
x + 7 = - 2x + 19 ( add 2x to both sides )
3x + 7 = 19 ( subtract 7 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
substitute x = 4 into either of the 2 equations for y
y = x + 7 ⇒ y = 4 + 7 = 11
solution is (4, 11 )
Answer:
x^2-16
Step-by-step explanation:
Foil Method
(x*x+4x-4x-16)
x^2-16
2 √141
First change the root to a fraction
√141 = 11.87, which, rounding up (as 8 > 5) = 12
Multiply 2 with 12
2 x 12 = 24
24 is your estimated answer
hope this helps
