Answer:
21x^2 - 23x - 20 = 0
Step-by-step explanation:
It's C and A since .2 times 30 is 6 and 1/5 is also .2
Answer:
1/3
Step-by-step explanation:
3x -9y =4
To find the slope get the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)
Subtract 3x from each side
-9y = -3x+4
Divide each side by -9
-9y/-9 = -3x/-9 +4/-9
y = 1/3x -4/9
The slope is 1/3 and the y intercept is -4/9
Answer:
16
Step-by-step explanation:
4^2 = 16
4×4=16 thats the answer
