Answer:
The amount is $1480.24
Step-by-step explanation:
We are given
he puts $1000 in a savings account earning 4% annually after 10 years
so,
P=1000
r=4%=0.04
t=10
now, we can use formula

now, we can plug values


So,
The amount is $1480.24
Step 1:
The variable is the number of weeks needed to equalize Alexa and her sisters savings.
Step 2:
7x + 60 = 5x + 120
Step 3:
7x+60=5x+120
Subtract 60 from both sides.
7x+(60-60)=5x+(120-60)
7x=5x+60
Subtract 5x from both sides
7x-5x=5x+60-5x
2x=60
Divide both sides by 2.
2x/2 = 60/2
x=30
Step 4:
7(30) + 60 = 5(30)+ 120
210+60=150+120
270 = 270
Step 5:
To find the unknown amount of weeks, you need to rewrite the equation isolate x on the left-hand side of the equation. I just subtracting/simplified the equation until I could solve it.

The answer is A. -5 all others are too big
The value of function f(x) = x+4 when x=3 is 7.
By considering given function
f(x) = x+4
f(3)= 3+4
f(3)=7
A mathematical expression, rule, or law that establishes the relationship between an independent variable and a dependent variable (the dependent variable). In mathematics and the sciences, functions are fundamental for constructing physical relationships.
Four broad categories can be used to classify different types of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element.
