Answer:
<u>6</u><u>c</u><u>²</u> + <u>2c</u> + <u>1</u>
Step-by-step explanation:
- 4 + 4c + 3c² - 2c + 3c² - 3
Rearrange the experresion.
- 4 - 3 + 4c - 2c + 3c² + 3c²
Combine like terms.
Use the commutative property to reorder the terms.
- <u>6</u><u>c</u><u>²</u> + <u>2</u><u>c</u><u> </u> + <u>1</u>
(x + 3)/(4 - x) = 13/15
15(x + 3) = 13(4 - x)
15x + 45 = 52 - 13x
15x + 13x = 52 - 45
28x = 7
x = 7/28 = 1/4
Therefore, 1/5 is not a solution
To find the area of a quarter circle, you simply take a quarter of a full circle. As all quarters are equal, this means that the formula would be <span><span>π<span><span>r2</span>4</span></span><span>π<span><span>r2</span>4</span></span></span><span>. But wait, there's more. If you notice, </span><span><span>π<span><span>r2</span>4</span>=π<span><span>r2</span>2</span></span><span>π<span><span>r2</span>4</span>=π<span><span>r2</span>2</span></span></span><span>. This coincides with the circle formula, just with half the radius. Notice anything? A quarter of a circle can be calculated in the same way a circle a quarter the size can. This means that a quarter circle is equal to a circle a quarter size. In this same way, a ninth of a circle is equal to a circle of one ninth the size.</span>
*Remember that slope : is y=mx+b
And m is slope and b is the y-intercept -
In this equation y-6=2(x+3)
m is 2 because if u multiply 2 to (x+3) it will become 2x+6
since m is 2 and b is 6
The slope is 2
And the y-int. is 6
So the slope is 2.
