Answer:none of these.
Try to substitute any of the given values for x and the result is false
Step-by-step explanation:
Try x=1. 1-7 -6. Divide that by 1 and you get -6 = 6. False!
To solve the given equation, multiply sides by x to cancel the denominator. You get x-7 = 6x then subtract x from both sides to get -7=5x. Divide both sides by 5 to get x= -7/5
But if the original equation has an x^2 somewhere, there will be a different set of solutions.
Formula for volume:
πr^2(h/3)
Diameter divided by 2 is the radius
18/2 = 9
radius: 9 units
Use pythagorean theorem to find height
x^2 + 9^2 = 15^2
225 - 81 = 144
x^2 = 144
x = 12
height: 12 units
Plug these number in the volume formula.
Thus, it should be looking as:
π9^2(12/3) = 1017.88
Answer:
1017.88 
Yes,
There is a direct proportional relationship
between the cost of items before tax and the
cost of items after tax.
5.0
Step-by-step explanation:
Given - A city has a 5% sales tax.
To find - Is there a proportional relationship
between the cost of items
before tax and the cost of items after
tax?
Proof
Yes, cost of items before tax is directly
proportional to cost of items after tax.
Reason
With the increase in the sales tax, there is
increase in the cost of items after tax, therefore,
there is a direct relation between cost of items
before tax and cost of items after tax.
Answer:
<u>Use 2 points from he table to find the slope of f(x):</u>
<u>The slope is:</u>
The y - intercept is b = -1 according to point (0, -1).
<h3>Part A</h3>
<u>The lines are:</u>
- f(x) = 8x - 1
- g(x) = 3x - 2
The f(x) has greater slope since 8 > 3 and greater y-intercept since -1 > - 2.
<h3>Part B</h3>
See above
