Step-by-step explanation:
{(-3, -3),(-6, -7), (6,-3), (–9, 2)} {(8,–8), (-9,5), (9,-2), (-2,-8)}
{(-7, -3), (-6, -1), (-6,8), (6, -6)}
Answer:
11/5-1/2 = 22/10-5/10= 17/10 = 1 7/10
The answer is 1 7/10
B, D
36/40 simplified is 9/10
9/10 x 2 = 18/20
I hope this helps!
2(4+x)
"Twice the sum of" tells us it will be the equation times two
"the sum of four and a number" is easy, thats 4 + x
The second number is x because the number is not specified so we need a place holder, x in this case, to tell us that the number is not given.
All this put together = twice the sum of four and a number, or <u>2(4+x)</u>
