Answer:
x = -5
Step-by-step explanation:
Combine them like terms,then you subtract 4 from both sides,and then Simplify
New perimeter will be equal = old perimeter*3=36*3=108
Answer:
9. n=-15 , 10. f=6, sorry i can't help you more I am just tired and have to get some rest but i hope this helps
Step-by-step explanation:
9. Eight less than 1/3 a number n is -13
so -13 = 1/3n -8
then
-5 = 1/3n
multiply 3 to each side
-15 = n
10. a number f multiplied by -12.3 is -73.8
so -12.3f= -73.8
divide -12.3 on each side
so f=6
Answer:
-3/5x + y = - 26/5
Step-by-step explanation:
First, I put everything in slope-intercept form, just because it's more simple for me.
y = 3/5x + b
Since we don't have b, we can use the coordinate they give us to solve for it.
-4 = 3/5 (2) + b
-26/5 = b
y = 3/5x - 26/5
Now, we can move the variables around to fit the form:
Ax + By = C
-3/5x + y = - 26/5
I hope this helped!
