I think the answer is 147
Answer:
a) is a solution of the linear equation.
b) The rate of change of the equation is 3.
c) The y-intercept of the equation is -2.
d) <em>Jayne is working in the grocery one day, according to her calculations, renting the lot costs 2 dollars per day and she could earn 3 dollars per hour by selling pastries. How much money does she earn after working 8 hours?</em>
Step-by-step explanation:
a) If is a solution of the linear equation, then . If , then the function evaluated at this value is:
Hence, is a solution of the linear equation.
b) The rate of change of the equation is represented by the slope of the function, which is the constant that multiplies the indepedent variable (). Hence, the rate of change of the equation is 3.
c) The y-intercept of the equation is the only constant of the equation. Hence, the y-intercept of the equation is -2.
d) A real-world scenario would be the following: <em>Jayne is working in the grocery one day, according to her calculations, renting the lot costs 2 dollars per day and she could earn 3 dollars per hour by selling pastries. How much money does she earn after working 8 hours?</em>
Answer:
33 dollars
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given system of equations in the question are,
-3x + y = -6
y =
We can rewrite these equation as,
-3x + y = -6
y = 3x - 6 ------(1)
Table of input-output values for this equation will be,
x 0 1 2 3 4
y -6 -3 0 3 6
y = ------(2)
Table for this equation will be
x 0 2 4 6 8
y -1 0 1 2 3
By plotting these points on the graph we find (2, 0) is a common point in both the tables,
Therefore, (2, 0) is the only one solution of the given system of equations.
