Mathematics

liberstina [14]2 years ago

Answer:

Step-by-step explanation:

<u><em>(1).</em></u> (x - <em>h</em>)² + (y - <em>k</em>)² = <em>r</em>²

where <em>(h, k)</em> are coordinates of a center of the circle with radius <em>r</em>

<u><em>(2).</em></u> ( a ± b )² = a² ± 2ab + b²

~~~~~~~~~~~~~~

( 1 , - 2 ) ; r = 3

( x - 1 )² + ( y + 2 )² = 3²

x² - 2x + 1 + y² + 4y + 4 = 9

x² + y² - 2x + 4y - 4 = 0

a = - 2

b = 4

c = - 4

What is the equation of the line that passes through the point (-2,3) and is parallel to the line whose equation is y = 3/2x - 4
Kisachek [45]

Answer:

y = 3/2x + 6

Step-by-step explanation:

y = 3/2x - 4

y-intercept through point (-2, 3):

3 = 3/2(-2) + b

3 = -3 + b

b = 6

Equation of line:

y = mx + b

y = 3/2x + 6

**Parallel line share the same slope, in this case 3/2.

I need the answers for 1 a-d pleas ​

We want to find a fraction that is between

\frac{1}{4}\:and\:\frac{1}{2}

There are several ways to go about this.

There are also infinitely many fractions that can be found between the given fractions.

Let us go for the one in the middle of the two fractions.

So we add the two fractions and divide by 2.

a) \frac{\frac{1}{4} +\frac{1}{2} }{2}

Find LCM for the numerator

\frac{\frac{1+2}{4}}{2}

Simplify:

\frac{\frac{3}{4}}{2}

\frac{\frac{3}{2}}{2}

\frac{3}{8}}

b) \frac{\frac{1}{3} +\frac{3}{4} }{2}=\frac{13}{24}

c)\frac{\frac{1}{2} +\frac{3}{4} }{2}=\frac{5}{8}

d)\frac{\frac{3}{5} +\frac{7}{8} }{2}=\frac{59}{80}
