Sqrt [(-4 -(-7)^2 + (6-3)^2 ]
= sqrt (9 + 9)
= sqrt 18
which can also be written as sqrt 9 * sqrt 2 = 3 sqrt 2
49/12
Just mulitply the top and the bottom across.
7*7/4*3
49/12
Y=40+5x
For an example, say Mia wanted to add $5 into her account each week for 2 weeks.
y=40+5(2)
5(2)=10
y=40+10
y=50
Mia will have a total of $50 in her account if she added $5 for each week for 2 weeks. Same for Juan, his equation will be based off his amount y=15+10x

if you're wondering about the restriction of x ≠ -4, is due to that would make the fraction with a denominator of 0 and thus undefined.
Answer:
If you want it as the previous number without being a percent you just have to multiply the percent by 100 to get the previous amount. For example:-
to convert 30% to a number put in a fraction form and multiply it by 100
You can find the previous value of any percent by doing this.
