Answer:
x = 1.875
Step-by-step explanation:
<u>Step 1: Distribute</u>
1/2x + 3/2(x + 1) - 1/4 = 5
1/2x + 3/2x + 3/2 - 1/4 = 5
<u>Step 2: Combine like terms</u>
4/2x + 6/4 - 1/4 = 5
2x + 5/4 = 5
<u>Step 3: Subtract 5/4 from both sides</u>
2x + 5/4 - 5/4 = 5 - 5/4
2x = 3.75
<u>Step 4: Divide both sides by 2</u>
2x / 2 = 3.75 / 2
x = 1.875
Answer: x = 1.875
Answer:

Step-by-step explanation:
The given quadratic functions are:



We want to order these functions, from the widest to the narrowest.
How wide the graph will open depends on the absolute value of the coefficient of the function.
The smaller the absolute value of the coefficient, the wider the graph.
Since

Therefore from the widest graph to the narrowest graph, we have:

Answer:
x = 360 - 49 - 136 - 69 = 106°
Answer:
For question 3, the slope would be -5
Step-by-step explanation:
If you wanted to graph this you would have to plot one of the points that is already given. Then from that point, you would move 5 units down and 1 unit to the right. If you run out of space, you can go to the other direction by going 5 units up and 1 to the left.
Hope this helps :)
