Alighthouse is located at (1, 2) in a coordinate system measured in miles. a sailboat starts at (-7, 8) and sails in a positive x-
direction along a path that can be modeled by a quadratic function with a vertex at (2,-6). which system of equations can be
used to determine whether the boat comes within 5 miles of the lighthouse?

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
