Joanna deposited $132000 and her interest amount is $359730.35
<u>Step-by-step explanation:</u>
Monthly deposit = $275
Interest = 5.6%
Time = 40 years
After 40 years her account balance = $491730.35
If she deposit $275 monthly then after 40 years she will have deposited ,
= 275 x 12 x 40
= $132000
The remaining is her interest amount.
Interest amount = 491730.35 - 132000
= $359730.35
Joanna deposited $132000 and her interest amount is $359730.35

Step-by-step explanation: 16
Answer:
y = 3x + 2
Step-by-step explanation:
So we can use the point-slope equation to help us figure out our y = mx +b equation
First we need to choose two points on the graph so we can calculate our slope
I personally like to choose point that intersects two numbers perfectly on the line rather than a point that is maybe half way between two numbers
So we can use the point (0,2) and the point (2,8)
Our (0,2) will represent (x₁, y₁) and our (2,8) will represent (x₂,y₂)
The equation to find the slope is 
, so plugging in our values, we get 
We have found our slope, 3, and now we can use the point-slope equation: y - y₁ = m(x - x₁) to figure out the remainder of the equation.
Plugging in our values we get: y - (2) = (3)(x - (0)) which simplifies to y - 2 = 3x which then simplifies to y = 3x + 2
Answer:
linear
Step-by-step explanation:
First differences of the y-values for the consecutive x-values are ...
-3 -(-4.5) = 1.5
-1.5 -(-3) = 1.5
0 -(-1.5) = 1.5
1.5 -0 = 1.5
The first differences are constant, so the function is linear.
__
Since we know the function is linear, there's no real point in computing the ratios of successive outputs. In any event, we know it is not constant. The ratio with 0 as a numerator will be 0; the ratio with 0 as a denominator will be undefined.
47x5= 235
235 divided by 5 =47
Neals number could be 47
