If you do not mind me asking, what did Seth write? Us helpers cannot answer it if we do not have the full question. I apologize if this seems rude.
30 is the old value and 55 is the new value. In this case we have a positive change (increase) of 83.33333333 percent because the new value is greater than the old value. Using this tool you can find the percent increase for any value.
Answer:
She did no divide each addend correctly
Step-by-step explanation:
Given
12 + 32 ← factor out 4 from each addend
= 4(3 + 8)
As 4 × 3 = 12 and 4× 8 = 32
Valerie had 12 + 32 = 4(1 + 10) ← incorrect statement
You can solve for x and y in terms of z, then let z take on the value of the parameter.
Subtracting the first equation from the second, you get
... x_2 +x_3 = 1
Subtracting that from the first equation gives you
... x_1 +2x_3 = 3
Let x_3 = t. Then your parametric equations are ...
