Answer: When a = 8, one of the roots of the equation will be 1.

To solve this problem, you could graph the equation with a 1 in the place of the a on a graphing calculator (there are some online).

Then, just keep changing the a value until the graph crosses the x-axis at 1. When, you enter an a value of 8, it will have a root of 1.

Answer:

C) 16, 6

Step-by-step explanation:

  1. Set AB and DC equal to eachother. 4x = x + 12.
  2. Subtract x from both sides. 3x = 12
  3. Divide by 3 to get x alone. x = 4
  4. Plug this x value in the equation for AB. 4•(4) = 16
  5. We know the AD equals 6, so that will be one of the values and we now know that AB equals 16.

Find the inequality represented by the graph. Thanks!<br><br> (plz no spam...)
nikitadnepr [17]

Answer:

y > (1/3)x - 3.

Step-by-step explanation:

The graph of a line can be written in y = mx + b form where b is the y-intercept and m is the slope.

In the image, the slope of the graph from the given points is 1/3.

In the image, the y-intercept is -3.

Therefore, the line is y = (1/3)x -3. However, we aren’t done yet! This is an inequality, not an equation!

We see the line isn’t dotted, so that means it must be > or <.

We substitute the point (0,0) into the line equation we got and find that 0 > (1/3)(0) - 3 = -3. Since (0,0) is part of the inequality, we have that y > (1/3)x - 3.

I hope this helps! :)
