Answer: y = (xm)/3 + b
Step-by-step explanation:
1. Multiply m on both sides
x × m = 3(y - b)
2. Divide by 3 on both sides
(xm)/3 = y - b
3. Add b on both sides
y = (xm)/3 + b
Answer:
see explanation
Step-by-step explanation:
The solution to the equations is at the point of intersection of the 2 lines.
If the system has no solution, this indicates the lines do not intersect and therefore must be parallel.
Answer:
Step-by-step explanation:
Using the Pythagorean identity
sin²x + cos²x = 1, then
sinx = 
Note that (
)² = 
sinΘ =

Answer:
Aries originally had 48 cookies
Step-by-step explanation:
2 is half of 4
4 is 1/4th of 16
16 is 1/3rd of 48
check work by reversing steps:
Aries had 48 cookies, she gave 1/3 (16) to Ana. Ana gave 1/4th (4) to Edna, and Edna gives 1/2 (2) to Ruth.
Ruth has 2, so the work is correct.
Solve for n.
0.2(n - 6) = 2.8
Distribute
0.2*n - 0.2*6 = 2.8
0.2n - 1.2 = 2.8
Now inverse operation should be applied
0.2n - 1.2 = 2.8
+ 1.2 +1.2
2.8 + 1.2 = 4
0.2n = 4
0.2n/0.2 = 4/0.2
n = 20
Answer: 20
