4x+2y>8
X-int. is when y is 0
4x+2(0)>8
4x=8
x=2
X-int. is (2,0)
Y-int. is when x is 0
4(0)+2y>8
2y=8
y=4
Y-int. is (0,4)
Answer:
using the 7% interest rate the interest rate is 168 due to the fact if you take 2400 x .07 you get 168 however I don't know if it asks that but in order to see exactly how much money would be in there you would have to add the 168 to the 2400 if you are to add that to the 2400 that was originally put in the bank you would come up to 2568
G ( x ) = 4 x + 1 ( spots → stars )
h ( x ) = x² - 2 ( stars → asteroids )
Composite function:
h ( g ( x ) ) = ( 4 x + 1 )² - 2 =
= 16 x² + 8 x + 1 - 2 =
= 16 x² + 8 x - 1 ( spots → asteroids )
We can start by solving for 10-5a+(18-b). By plugging in a and b, we get
10 - 10 + (18 - 11)= 7
28 ÷ (a × 2) = 28/4 = 7
20 + b − (4 × a) = 31 - 8 = 23
49 − 43 + (a ÷ a) = 49 - 43 + 1 = 7
30 − 25 + (b − 9) = 5 + 2 = 7
50 ÷ a − (b + 20) = 25 - 31 = -6
So, 28 ÷ (a × 2), 49 − 43 + (a ÷ a), and 30 − 25 + (b − 9) will all have the same answer as 10−5a+(18−b)
