A college received 90% of its order of laptop keyboards from a vendor.
1 answer:
Answer:
170
Step-by-step explanation:
Given that: x represents total number of keyboards ordered
y represents number of non-defective keyboards
And;
y = 0.9x - .......................... 1
If the college ordered 200 keyboards, then x = 200. So that substituting the value of x in equation 1, we have;
y = (0.9 x 200) -
= 180 -
= 180 - 10
y = 170
The college received 170 non-defective keyboards.

The vertex is identified by the fact that the y-values are symmetrical either side of the vertex.
