Answer:

First Question: A

Second Question: A

Step-by-step explanation:

First question

The trick is to be able to copy and place the graph so that the two coordinate systems are the same. Desmos is very good at that kind of thing. The graph is given to you on the right upload.

From this you can see that the points that solves the inequalities is anything to the left and above the point (4.8,0.4) which is marked. Therefore the answer is DACK which is A

Part B

The problem is in the testing. You can build 20 children's bikes and 6 adult bikes in less than 120 hours.

Building:20*4 + 6*6 = 80 + 36 = 116 hours. that's less than 120 so you're good

Testing: 20 + 6*4 = 80 + 24 = 104 hours. That's not less than 100.

The answer is A

Can someone help me?

soldier1979 [14.2K]

Answer:

Step-by-step explanation:

First your going to plug in what p and q are into the equation so 3(2)^5+10(-3)^2 over 7(2)+1.

Your going to first do (2)^5 and (-3)^2 so it’s going to be 3(32)+10(9) over (multiply the 7(2) first) 14+1.

3(32)+10(9) over 14+1 now multiply 3(32) and 10(9) you should get (96)+(90) over 15.

add 96+90 to get 186 over 15.

then divide how many times 15 can go into 186 you should get 12 6/15 and divide 6/15 by 3 to get your final answer 12 2/5.

I hope this helps!

The first three steps for solving the quadratic equation by completing the square are shown. Fill in the missing number in the l

gulaghasi [49]

Completing the square is done as follows:

1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
9x2 +54x = 7

2. Make sure that the coefficient of the x^2 term is 1.
9(x2 + 6x) = 7

3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
9(x2 + 6x + 9) = 7 + 81

9(x+3)^2 = 88
