Point k is located on the y-axis 8 units away from the origin. what are the coordinates of point k

Given:

Point k is located on the y-axis 8 units away from the origin.

To find:

The coordinates of point k.

Solution:

Since point k is located on the y-axis, therefore it means the x-coordinate is 0.

Point k is 8 units away from the origin. So, it can be either or positive or negative side of y-axis.

If k is on the negative side of y-axis then y-coordinate of point k is -8.

If k is on the positive side of y-axis then y-coordinate of point k is 8.

Therefore, the possible coordinates of point k are either (0,-8) or (0,8).

idk what the heck he answer is, i’m just putting this here so i finish my account

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
