For the question mark, we can insert a variable considering it is an unknown number.
The answer should be -14(2+v^6) if I’m correct
3x -4 (5 - x) = 7x -20
3x-20+4x=7x-20
7x-20=7x-20
Answer:
40% change
Step-by-step explanation:
6/10=40%
Answer:-2/5
Step-by-step explanation:
Now the above equation can be rewritten as 5y= -2x+1
Dividing this expression through by 5, we have 5y/5 = -2x/5 + 1/5
y= (-2/5)x + 1/5
Comparing with the general equation of a line;
y = mx + c; m= gradient; C= constant along the y-axis
m= -2/5
