Answer:
Because we know for a fact that the line has a correct answer. Plus, if you choose a point on the line then it will not give you the visual side of which is correct and which is wrong.
Step-by-step explanation:
If you choose a point on the line then it will not give you the visual side of inequality. Therefore, choose the interval.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade. If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line. For a vertical line, larger solutions are to the right and smaller solutions are to the left.

Answer:
JK = 50; IJ = 25√3
Step-by-step explanation:
HAVE: sin ∠J = sin 30° = [tex]\frac{IK}{JK}[/tex]
=> [tex]\frac{IK}{JK}=\frac{25}{JK}=\frac{1}{2}=> JK = 25.2 = 50[/tex]
cos ∠J = cos 30° = [tex]\frac{IJ}{JK}[/tex]

We know that d equals the dollar amount needed to buy one hundred seventy-six tickets.
Fill in the proportion using the ratios highlighted in the table.
Answer:
d = 110
Step-by-step explanation:
From the table of values given, we know that the ratio of dollar to ticket is 5 : 8.
Therefore, the amount of dollar to 176 dollars would be d : 176.
Using this proportion, we can find the value of d as shown below:
5 : 8 = d : 176
[tex] \frac{5}{8} = \frac{d}{176} [/tex]
Multiply both sides by 176
[tex] \frac{5}{8}*176 = \frac{d}{176}*176 [/tex]
[tex] \frac{5*176}{8} = d [/tex]
[tex] \frac{880}{8} = d [/tex]
[tex] 110 = d [/tex]
d = 110
Answer: The answer is d simply d

Solve for y
a. 4x + 5y = 25
Answer:
y = -4/5x + 5
Step-by-step explanation:
In order to solve for y, we need to isolate the variable. First, let's subtract 4x on each side. After doing said step, we should now have this equation:
5y = -4x + 25
Next, we need to divide 5 on each side, giving us this new equation:
y = -4/5x + 5

7. What number is 32% of 79?
A.n= 32.79: 2.528
B.32 = n. 79: 0.4
C.79=n.0.32: 246.9
D.n-0.32.79; 25.3
Answer:
If they're asking you to round, I'll choose D just because 25.28 is 25.3 rounded to the nearest tenth.
Step-by-step explanation:
79/x=100/32
(79/x)*x=(100/32)*x - we multiply both sides of the equation by x
79=3.125*x - we divide both sides of the equation by (3.125) to get x
79/3.125=x
25.28=x
x=25.28

Compare 6.23 * 10^14 and 8.912 * 10^12
Answer:
623,000,000,000,000 > 8,912,000,000,000
Step-by-step explanation:
8.912·10^12
The exponent is 12, making it 10 to the power of 12. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 12 time(s):
8.912 -> 8,912,000,000,000
6.23·10^14
The exponent is 14, making it 10 to the power of 14. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 14 time(s):
6.23 -> 623,000,000,000,000
If Ryan does a job in 10 hours and with the help of Molly they can do it together in 3 hours, how long would it take Molly to do it alone?
Answer:

1. In the office, there is a filing cabinet that is 1 foot wide, 3 feet deep and 3
feet tall. You have hundreds of file folders to put into this cabinet.
Assuming that each folder is 12 inches wide, 1 inch thick, and 9 inches
tall, how many folders can you fit into this cabinet? (Draw a picture!)
Answer:
the answer is 144 folders
Step-by-step explanation:
you have to convert the ft of the file cabinet to inches. so the cabinet is 12 in wide, 36 in deep and 36 in tall. the volume of it is 15,552 cu in. each folder is 108 cu in. divide 15,552 by 108 = 144 folders can fit in the cabinet. sorry my pic is messy.
