Write the equation of a line for the graph:
Answer: y=1/3x-2
Step-by-step explanation:
To find the equation of the line, we need the slope and y-intercept. To find the slope, we can take any two points on the graph and use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. To find the y-intercept, we find the point that crosses the y-axis. The two points on the graph are (0,-2) and (3,-1).
[tex]m=\frac{-1-(-2)}{3-0} =\frac{1}{3}[/tex]
Now, we know the slope is 1/3.
The graph crosses the y-axis at (0,-2). Therefore the y-intercept is -2. This tells us that the equation is y=1/3x-2.

What is a value of b will cause 27x^2+ bx +3 = 0 to have one real solution?
Answer:
The values of b are [tex]\mathbf{b=\pm18}[/tex]
Step-by-step explanation:
We need to find the value of b will cause [tex]27x^2+ bx +3 = 0[/tex] to have one real solution.
If it has one real solution, the discriminant is zero.
The formula of discriminant is: [tex]b^2-4ac[/tex]
In our case: [tex]b^2-4ac=0[/tex]
We have a=27, b=b and c=3
Putting values to find b
[tex]b^2-4ac=0\\b^2-4(27)(3)=0\\b^2-324=0\\b^2=324\\Taking \ square root \ on \ both \ sides\\\sqrt{b^2}=\sqrt{324}\\b=\pm18[/tex]
So, the values of b are [tex]\mathbf{b=\pm18}[/tex]

A certain radio station plays classical music during 20% of its airtime. If the station is on air 24 hours a day, how many hours each day is the station playing classical music?
Answer:
4.8 hours
Step-by-step explanation:
20% of 24 hours is the product of the decimal form of 20% (which is 0.2) times 24.
The answer is:
0.2 * 24 = 4.8 hours which is the same as 4 hours and 48 minutes.

In the diagram, assume that y= 7. Find x and z.
A)
<= 7 V3; 2= 14
B)
x = 14; 2= 7 V3
©
x= 7 V2; 2 = 14
D)
x = 14; 2= 7V2
Answer:
A
Step-by-step explanation:
- to find x we use tan 60 = x/7
- rearrange, tan60*7 = x, x = [tex]7\sqrt{3}[/tex]
- now you have two sides so you can use pythagoras to find z
y^2 + x^2 = z^2
z = [tex]\sqrt{(7\sqrt{3})^2 + (7)^2 }[/tex]
z = 14
