Answer:

its IJ

Step-by-step explanation:

well, its obvious buddy, its asking which line is REFLECTED on the X-AXIS, which is the horizontal line across the screen. (think of the sun setting on the horizon).

so like a mirror, it should be the opposite side and not reflected across the Y-AXIS. hope this helps 6th/5th grader...

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.

Answer:

Option B

Step-by-step explanation:

Given quadratic equation is,

12a² + 9a + 7 = 0

By comparing this equation with standard quadratic equation,

hx² + kx + c = 0

h = 12, k = 9 and c = 7

By using quadratic formula,

a = $\frac{-k\pm\sqrt{k^2-4hc}}{2h}$

= $\frac{-9\pm\sqrt{9^2-4(12)(7)}}{2(12)}$

= $\frac{-9\pm\sqrt{81-336}}{2(12)}$

= $\frac{-9\pm\sqrt{-255}}{24}$

= $\frac{-9\pm i\sqrt{255}}{24}$

a = $\frac{-9+ i\sqrt{255}}{24},\frac{-9- i\sqrt{255}}{24}$

Therefore, Option B will be the correct option.

Does anyone know the slope of this table?

ArbitrLikvidat [17]

Answer: the slope is 2/1 or 2

Step-by-step explanation: slope is written rise over run, meaning y/x. By finding the difference between 13/5 and 17/7, then 17/7 and 21/9 to confirm, you can see that the difference is 4/2, which reduces to 2/1, which is simplified to 2.
