The ' c ' in 'gcf' and in 'lcm' stands for 'common'. 'Common' means 'same for all of them'. There's nothing common until you have at least two things. There's no such thing as the gcf or the lcm of only one number.
Answer:
h. I dont understand the question-
i. 2w + 5
j. 7m + 13s (I didnt get the second number)
k. -2x + 3y (I also didnt get the first number-)
l. 5c - 2d
m. 10a + 2g
n. 5a + 12
Step-by-step explanation:
For a linear function, you want it in y= mx + b form
They give you the slope your x, and when they say f(7)=1 that's like saying when x=7, y=1, or the ordered pair (7,1). To make it in y=mx+b, you can plug these coordinates in to solve for b. So, 1=7(7)+b, after you plug in slope and your point. Do math, 1=49+b, b=-48
That's how I think it's done
<span>the system has a unique solution if and only if the determinant of the coefficient matrix does not equal zero. </span>
