Answer:
$ 121.29
Step-by-step explanation:
849 / 7 = 121.28571428571
rounded to 121.29
11x+3y=103 and y=3x+1.
11x+3(3x+1)=103 -----> plug in (3x+1) for y in the first equation. You will want to distribute the 3 to the 3x+1 to get something that looks like:
11x+9x+3=103 ------> now you want to combine like terms
20x+3=103 ---> subtract 3 from both sides
20x=100 ----> divide both sides by 20
x=5
y=3(5)+1 ---> I like to plug in this to the equation that already has y isolated. 3*5 is 15, add 1 and you find that y=16.
(5, 16) will be your final answer (:
Answer:
y+7 = 4/3(x-9)
Step-by-step explanation:
Point slope form of an equation of a line is
y-y1 = m(x-x1) where (x1,y1) is the point and m is the slope
y--7 = 4/3(x-9)
y+7 = 4/3(x-9)
