Answer:
x=15
Step-by-step explanation:
Hey There!
So what we want to do is inverse operations from the formula of area of a triangle
The area is equivalent to
h=height
b=base
now we setup an equation with what we are given
we are given A (area) and h(height)
so the equation looks like...
now we solve for b (x)
step 1 multiply each side by 2
75x2=150
/2x2 cancels out
now we have
150=10b
step 2 divide each side by 10
150/10=15
10/10 cancels out
b=15
We can conclude that the base (aka x) is equal to 15
Answer:
The balance is 
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
Answer:
C. g(x) = -|x|
Step-by-step explanation:
|x| is an upwards v centered at the origin
- |x| is a downwards v centered at the origin
Third side must be greater than (12 -7) or 5 and less than (12 + 7) or 19
So, third side could be A C E or F
B 7.50 reason total spent=4+.50(7)——-> 4+3.50———->$7.50
