Basically to solve this problem 

firstly you will have to simplify this equation which will be
10x-4
Then you write it like this 10x-4=1
than you work out this algebraically
you have to get x on its own

The final answer is 0.5 x=1.5

Hope this helps

zloy xaker [14]
The probability that Lou's guess is correct would be 0 % of expressed as a percentage. This is because this is not one of the descriptions that Layla is thinking of, when she is thinking of a single digit number. 7 is not an even number, but an odd one.

What is the slope and y-intercept of the equation represented by the following graph?
Solnce55 [7]
Referring the chart I attached, the slope is the ratio of rise to run

So we need to pick two points lying on the line to calculate the slope.

They would be (4,0) and (0,2)

slope= \frac{rise}{run} = \frac{\Delta y}{\Delta x}=  
\frac{y_2-y_1}{x_2-x_1} = \frac{2-0}{0-4} = -\frac{2}{4} = -\frac{1}{2} 


That is for the slope

The y-intercept is where the line touches\crosses\intersects the y-axis...

It is clear from the figure that the line crosses the y-axis at (0,2)
so the<span> y-intercept is y=2

I hope that helps!

If you still need help, just let me know!

Find the value of w and then x. Round lengths to the nearest tenth and angle measures to the nearest degree.
VARVARA [1.3K]

Answer

w=7.6

x=43.7

Step-by-step explanation:

To solve for w you can use Sin(x)=\frac{Opposite}{Hypotenuse}  which would basically be Sin(50)=\frac{w}{10} then solve. Multiply the ten on both sides so you have 10*Sin(50)=w and your final answer is 7.6

To solve for x you can also use Sin(x)=\frac{7.6}{11} then just use Inverse of Sin^-1

The answer is x=43.7

Graph the linear equation<br> 6x-2y=8
shtirl [24]

Answer:

  see attached

Step-by-step explanation:

A graphing calculator can help you with this.

It is often useful to graph the intercepts and draw a line between them. Here, the x-intercept is 4/3, so graphing that may not be easy.

It might be easier to recognize that changing the value of x by 1 will change the value of y by 3. Starting at the y-intercept of -4, you can find that points (1, -1) and (2, 2) are also on the line.
