Answer:
20t+20 ≤ 93
20t ≤ 73
t ≤ 73/20, or 3.65
Lainey can dive for 3.65 more minutes.

Answer:solve for y
y -1/2x ≥ 4
y ≥ 1/2x + 4
The y intercept is 4, and the slope is positive, so the only graph with that conditions is B.
Step-by-step explanation:
B is false. You cannot square a 3x1 matrix.
In order to multiply matrices, the number of columns of the first matrix must match the number of rows of the second matrix. To square a 3x1 matrix, you would be multiplying a 3x1 by a 3x1; the number of columns in the first one is 1, but the number of rows of the second matrix is 3. They are not compatible.
Answer:
y-intercept is (0, 2) and the slope is 1
