Write the equation of a line for the graph:

Answers

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.

In the diagram, assume that y= 7. Find x and z.
A)

B)
x = 14; 2= 7 V3
©
x= 7 V2; 2 = 14
D)
x = 14; 2= 7V2

Answers

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

Question 5
What is a value of b will cause 27x^2+ bx +3 = 0 to have one real solution?

Answers

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]
