Answer:
4760
Step-by-step explanation:
Simple interest= principal× time ×rate/100
=3500×4×9/100
= 1260
Amount that will be in the bank after 4years= 3500+1260
=4760
Let’s say Peter’s number is P.
P minus 16 and the answer times -2 is -34
-2(P-16) = -34
-2P+32 = -34
-2P = -66
Divide by -2
P is 33.
Check: 33-16 is 17 and 17*-2 is -34. So
P is 33.
The signed numbers that represent a change in money from her perspective is:
+$25
+$14
-$10
-$3
+$2
<h3>What are the signs to put in front of the amounts?</h3>
When a person receives money, earns interst or his paid wages, the amount of money the person has increases. Thus, the sign to be used is the addition sign(+).
When a person pays for an item, donates to charity or loses money, the amount of money the person has reduces. Thus, the sign to be used is the subtraction sign (-).

Answer:
<h2>
y = 3x - 1</h2>
Step-by-step explanation:
Two lines are perpendicular if the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = -1/3x + 7 ⇒ m₁=-1/3
-1/3×m₂ = -1 ⇒ m₂ = 3
The y-intercept is b=-1 so the equation in slope-intercept form:
y = 3x - 1
