Answer:
-4x - 11
Step-by-step explanation:
-2[f(x)] - 1
= -2[2x + 5] - 1
= -4x - 10 - 1
= -4x - 11
Answer:
9.8
Step-by-step explanation:
1:49= ratio of carbon to to iron
1+49= steel
50=10pounds
49=?pounds
49 * 10/50
=49/5
=9.8pounds
Answer:
x=70
Step-by-step explanation:
To solve this problem, you set up the equation 45+(2x-5)=180
Next, subtract 45 from 180 to get the equation 2x-5=135
After that, add 5 to 135 to get 2x=140
Divide 140 by 2 to get X=70
Answer:
550 + 3x > 1000, where x > 150
The quantities true for x are: x must be greater than 150
Step-by-step explanation:
The question claims he wants to earn OVER 1,000 that month. He already makes $550 and $3 PER PLANT he sells. Subtract $550 from $1000 and you would get 450. Then divide by 3. That makes 150 plants. So now we know the x needs to be GREATER THAN 150 plants to make over 1,000. The x would also go next to the 3 because the 3 represents how much per plant sold, and the 150 represents how many plants. The equation would be $550 + 3x > 1000, where x > 150.
