Answer:
B) 1
Step-by-step explanation:
Since we are using elimination, we can just cancel 2y and -2y. No need of multiplying anything if we are just looking for x.
We add the equations and get:
9x=9
Then divide and the final answer is:
x=1

Answer:
-7/4.
Step-by-step explanation:
This is the difference in the y coordinates / corresponding difference in the x coordinates.
here it is (16 - 9) / (-3-1)
= 7 / -4
= -7/4.
1.70 - 0.45 = 1.25
1500 ÷ 1.25 = 1200

2,12, 1 ,24,3,8,4,3,6,
THese number has 24 as a multiple so they are actually factors

When the X term is one, and doesn't have a leading coefficient, then you can factor it using the box and diamond method. look up videos on Khan Academy of the box and diamond method for solving trinomials. For number 9, you have a difference of squares. That means you can factor to just 2 terms. (x+4)(x-4) this works because 16 has an easy square root, and the sign in between is a negative(difference)
