Answer:
y = -1/2x + (-1)
Step-by-step explanation:
She would pay $145 monthly
1600+5%(80)+60=$1740:12=145
The general form of sine curve is f(x) = a sin (nx)
Where: a is the amplitude and n = 2π/period
Given the points of the sine curve which is
(0, 0) and (160, 1) and (320, 0) and (480, -1) and (640, 0)
the maximum value of f(x) = 1 , and the minimum value of f(x) = -1
∴ amplitude = a =1
And the function complates one cycle from 0 to 640
∴ period = 640 ⇒⇒⇒ n = 2π/640 = π/320
∴ f(x) = 1 * sin (π/320)x = sin (π/320)x
∴ The correct answer is option d
<span>d) f(x) = sin pi over 320x</span>
Answer:
<h3>5x+10y=100</h3>
Step-by-step explanation:
X+Y = 15
<h3>Sum of two types of question is 15</h3>
x+y-x = -x+15
<h3>y= -x+15</h3>
5(x)+10(y)=100
5x+10y=100
<h3>Total no. if points is 100</h3>
5x+10y-5x=-5x+100
10y= -5x+100
y=5/10x + 100/10
y= -1/2x+10
<h3>Slope intercept form</h3>
(10,5)
Answer:
Step-by-step explanation:
We can add the same quantity to both sides of the equations, and still have an equivalent equation. Let's add 
to both sides, then sum like terms
(this is the rule that allows us to move items from one side do the other of the equal sign by changing its sign)
At this point we have a solution, let's replace it to verify
