Answer:
x ≥ 0
Step-by-step explanation:
It follows the general shape of exponential function.
It starts at y-intercept of 30,000 and moves towards x-axis as it moves to the right, decreasing [since loan balance is decreasing with time].
The graph DOESN'T go to left of x axis and goes towards infinity as it goes right.
The domain is the set of x-values that the function is defined for.
So we see it starts from x = 0 and goes towards infinity
Thus we can say it is x greater than or equal to 0.
WHich is x ≥ 0
Are you trying to subtract?
If so, the answer is -5,333.
here's a worksheet that might match what you're looking for
Answer:
≈ 108 m³
Step-by-step explanation:
You're searching for the volume of a cylinder. The formula needed to find it is V=πr²h.
In this case, the radius r is 1.4m and the height h is 35/2=17.5m, as it is only half filled.
Now when inserting values, you get: V=π*1.4²*17.5 which is 107.757 m³
<span>1. Make y the subject
a) 4y=12x+18
y = 3x + 4.5
b) 2x=7-3y
3y = -2x + 7
y = -2/3x + 7/3
2.
a) what is the equation of the line which passes through both (-2,-4) and (6,16)
slope = (16 + 4)/(6 +2) = 20/8 = 2.5
y = mx + b
-4 =2.5(-2) +b
-4 = -5 +b
b = 1
equation
y = 2.5x + 1
b) what is the equation of the line perpendicular to y= 1/2X + 7 passing through point (3,9)
</span>y= 1/2X + 7
slope = 1/2
slope of line perpendicular = -2
passing through point (3,9)
y = mx + b
9 = -2 (3) + b
b = 15
equation
y = -2x + 15
