2 green spaces, 2 star spaces, 2 question mark spaces
Answer:
2 ≤ x < 7
Step-by-step explanation:
-1 ≤ x – 3 < 4
Add 3 to each side
-1+3 ≤ x – 3+3 < 4+3
2 ≤ x < 7
Answer:
See answer below
Step-by-step explanation:
For the first expression
3 x (x - 2) + 2 = 3 x^2 - 6 x + 2
evaluated at x= 4 we get: 26
and for x = 5 we get 47.
For the second expression
2 x^2 + 3 x - 18
we get the exact same values when doing the evaluation at these two points.
Based on those results, one may think the expressions may be equivalent, but they are not equivalent. Because at any other x-value, their results are different. See for example that for x = 0 the first one gives "2" while the second one gives -18.
Answer:
(x) = 
Step-by-step explanation:
let d(x) = y and rearrange making x the subject, that is
2x - 4 = y ( add 4 to both sides )
2x = y + 4 ( divide both sides by 2 )
x = 
Change y back into terms of x, so
(x ) = 
Answer:
y = -3x -5
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercep
6x+2y = -10
Subtract 6x from each side
6x+2y -6x = -6x-10
2y = -6x-10
Divide each side by 2
2y/2 = -6x/2 -10/2
y = -3x -5
