the equations x+5y = 10, 3x-y = 1, x-5y = 10, and 3x+y = 1 are shown on the graph below.
which is the approximate solution for the system of equations x+5y = 10 and 3x+y = 1?
a. (–0.3, 2.1)
b. (–0.3, –2.1)
c. (0.9, –1.8)
d. (0.9, 1.8)

True or false look at the picture pls : /

Me asap on # : explain how factoring a trinomial, ax^2+ bx+ c, when a does not equal 1 different from factoring a trinomial when a = 1.

Ineed big ! the cost of a school banquet is $25 plus $15 for each person attending. create a table, sketch the graph, and write an equation in slope-intercept and point-slope form that gives total cost as a function of the number of people attending. what is the cost for 77 people?
