In this point x=10, y=-4, reflect it across the y-axis=flipping it through the vertical line, the y-point does not change while x-point gets turned into it's opposite
the answer is (-10,-4)
Answer:
Step-by-step explanation:
first graph
<h2>height=constant* width ( direct variation describes a linear relation between 2 variable )</h2>
6=8x ⇒ x=6/8=0.75
h=0.75w
<h2>constant is 0.75</h2>
second graph:
<h2>height=constant/width ( inverse variation)</h2>
15=x/4 ⇒x=4*15 ⇒x=60
<h2>constant=60</h2>
For two quantities with inverse variation, as one quantity increases, the other quantity decreases. k(constant)=xy
Use the formula of the present value of annuity ordinary to find the monthly payment of the loan
The formula is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value 75500
PMT monthly payment?
R interest rate 0.065
K compounded monthly 12
N time 40 years
So we need to solve for pmt
PMT=Pv÷[(1-(1+r/k)^(-kn))÷(r/k)]
PMT=75,500÷((1−(1+0.065÷12)^(
−12×40))÷(0.065÷12))
=442.02 (this is the monthly payment)
Now find the amount of interest
Total interest=total paid-present value
Present value=75500
Total paid
442.02×12months×40years
=212,169.6
Total interest=212,169.6−75,500
=136,669.6
The answer is 136,669.6
Answer:525 boys
Step-by-step explanation:
Multiply 1250 times .58 and then subtract that answer from 1250....
1250x.58=725
1250-725=525
