Answer:
<em>600π feet</em>
Step-by-step explanation:
<em>If the radius is 18 inches, the diameter is 3 feet. The circumference of the tire is therefore 3π by C=d(π). After 200 revolutions, the tire and car have gone 3π x 200 = 600π feet.</em>
Answer:

Step-by-step explanation:
<u><em>The question is</em></u>
Which equation should she use?
we have the formula

Solve for k
That means ----> isolate the variable k
Multiply by 2 both sides

Divide by x^2 both sides

Rewrite

The general formula for the sum of the n terms of a geometric progression is:
Sn = A1 (1 - r^n) / (1 - r)
In this case, n = 8; A1 = - 11, r = -4
S8 = -11 (1 - (-4)^8) / (1 -(-4)) = 144,177
Answer: option c.
Answer:
2x + 3y = -6
-4x + 3y = 12
5x + 3y = }
x - y = 5
Step-by-step explanation:
Standard Form is
.
2x + 3y = -6, -4x +3y = 12, 5x + 3y = '?', and x - y = 5 are the equations that are in standard form.
'2x+3 = 6' does not have the 'y' to make it standard form.
'y = 2x + 5' is slope-intercept form.
