Evaluate the power,subtract the numbers then write all the numerator above the common denominator.
Through my research I found a question similar to this and found the right description matching answers: so we have to find the perimeter of this: ''Shape ABCD is shown. Point A is at negative 3, 5. Point B is at 1, 7. Point C is at 3, 3. Point D is at negative 1, 1.''
Answer would be C) 17.9
You want to get x on one side so you divide both sides by 7 and 35/7 = 5
Answer:
I think its X
Step-by-step explanation:
X=y-7
x=2-8y
both equal x so
subsitute y-7 for x in other equaton
y-7=2-8y
add 8y
9y-7=2
add 7
9y=9
divide 9
y=1
sub back
x=y-7
x=1-7
x=-6
(x,y)
(-6,1)
