Answer:
y = -4x + 5
Step-by-step explanation:
This linear function can be represented through the slope-intercept form, or y=mx+b. You already know your m value, 4, which is your slope. From there you can plug in your coordinate into the y and x values to find your y-intercept, or b.
y = mx + b
-3 = -4(2) + b
b = 5
Then you put it all together to form the equation f(x) = -4x + 5
Answer: C) x = 3, (x = 2 is an extraneous solution)
<u>Step-by-step explanation:</u>
- 
= 
- = 
Restrictions: <em>Denominator cannot equal zero</em> (x - 1 ≠ 0) and (x - 2 ≠ 0), so x ≠ 1 and x ≠ 2
- 
= 
x(x - 2) - 1(x - 1) = 2x - 5
x² - 2x - x + 1 = 2x - 5
x² - 3x + 1 = 2x - 5
<u> -2x + 5</u> <u>-2x + 5 </u>
x² - 5x + 6 = 0
(x - 2)(x - 3) = 0
x - 2 = 0 x - 3 = 0
x = 2 x = 3
NOTE: x = 2 is an extraneous solution because it is one of the restricted values.
Well because the line segment runs from the center of the circle to a point on the circumference, AB would represent the radius.
Answer:
7200
Step-by-step explanation:
{1800× (90)} ÷ 495 ÷ -(-22)
= 162000÷ 495÷ 22
= 162000×22÷ 495
= 7200
Answer:
2/25 mile or 422.4 ft
Step-by-step explanation:
2 miles divided by 25 people = 2/25 mile
We can convert from miles to feet.
1 miles = 5280 ft
2/25 miles * 5280 ft / mile = 422.4 ft
