Answer:

y intercept is 0

Step-by-step explanation:

y=2/3x+b

if x=0 y=0 (0,0)

if x=3, y=2 (3,2)

y=2/3x+b

2=2+b

b=0

Answer:

1. $\frac{9}{5}$

2. $-11\frac{1}{4}$

3. $10\frac{1}{8}$

4. $4\frac{17}{24}$

5. $-4\frac{7}{12}$

Step-by-step explanation:

In order to solve them you just have to multiply them and add them:

$3 (\frac{3}{5} )=\frac{15+3}{5}=\frac{18}{5}$

$-4\frac{1}{2} (2\frac{1}{2} )=-(\frac{9}{2} )(\frac{5}{2}) =-(\frac{45}{4}) =-11\frac{1}{4}$

$(-2\frac{1}{4} )(-4\frac{1}{2}) =(-\frac{9}{4}) (-\frac{9}{2} )=-\frac{81}{8} =-10\frac{1}{8}$

$3\frac{3}{8}+ 4\frac{1}{3}=7\frac{8+9}{24} =7\frac{17}{24}$

$-2\frac{1}{4} +-2\frac{1}{3}=-4\frac{7}{12}$

Answer:

x = -7, x = 1

Extraneous Solution: x = -7

Step-by-step explanation:

If |x - 5| is positive

$|x - 5| = 2(x + 1)\\\\x - 5 = 2x +2\\\\x - 7 = 2x\\\\-7 = x$

If |x - 5| is negative

$|x - 5| = 2(x + 1)\\\\-x + 5 = 2x + 2\\\\5 = 3x + 2\\\\3 = 3x\\\\x = 1$

Now, check for extraneous:

$|-7 - 5| = 2(-7 + 1)\\\\|-12| = 2(-6)\\\\|-12|=-12$

$|1-5|=2(1+1)\\\\|-4| = 2(2)\\\\4 = 4$

-7 is extraneous because the absolute value of |-12| ≠ -12

Lostsunrise [7]

Answer: 108π inches squared

Step-by-step explanation:

Formula : Area of sector = $\dfrac{\theta}{360^{\circ}}\times\pi r^2$

where , r= radius and $\theta =$

Given : A certain car's windshield wiper has a total length of 22 inches. As the wiper pivots it clears a sector with a central angle of 120 degrees.

If only 18 inches of the wiper cleans the windshield, then we take radius of the range of wiper cleaining = 18 inches

The area of the windshield that is wiped during each swing = Area of the sector made by wiper of with a central angle of 120 degrees.

$=\dfrac{120}{360}\times\pi (18)^2\\\\=\dfrac{18^2}{3}\pi=\dfrac{18\times6}{1}\pi=108\p\text{ inches}^2$

Hence, the area (in exact form) of the windshield that is wiped during each swing is 108π inches squared.
