Answer:
5
5Step-by-step explanation:
If you use the distance formula you can solve it pretty easily. The distance formula is:
d = 
The two points you want are A and D. A is (-1, -4) and D is (3, -1). Plug that into the formula...
d = 
d = 
d = 
d =

I can solve it in a different way if you want me to.
Answer:
5x + 6
Step-by-step explanation:
3X + 2X = 5X
4 + 2 = 6
5X + 6 IS SIMPLIST FORM
Let x = amount of mortgage (aka the amount by the bank)
25% of the monthly income of $3000 is 0.25*3000 = 750 dollars
So using this rule, the family can pay up to $750 per month on mortgage
1% of the amount loaned (x) is equal to this figure, so
0.01*x = 750
0.01*x/0.01 = 750/0.01
x = 75000
Therefore, the most expensive mortgage this family can afford is $75,000. Anything higher and they go over budget.
