Step-by-step explanation:
we have
This is a linear equation
The slope is equal to
The y-intercept is equal to the point ----> value of the function f(x) when the value of x is equal to zero
The x-intercept is equal to the point ----> value of x when the value of the function is equal to zero
using a graphing tool
see the attached figure
Answer:
(b)
Step-by-step explanation:
A suitable calculator or spreadsheet can find the matrix product for you. Here, the answer choices differ in their upper left term, so we can determine the correct choice by finding the value of that term. It is the dot product of the first row of B and the first column of A.
(5)(3) +(7)(3) +(3)(2) = 15 +21 +6 = 42
This matches choice B.
