Is (5,6.5) a solution to y= -1/2x + 9?

Jlenok [28]

6.5 = - 1/2(5) + 9

6.5 = - 2.5 + 9 which is the same as 6.5 = 9 - 2.5

6.5 = 6.5

So yes, this ordered pair IS a solution.

Answer:

Step-by-step explanation:

( $x_{1}$ , $y_{1}$ )

( $x_{2}$ , $y_{2}$ )

m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

parallel lines have the same slopes , perpendicular lines have slope which are opposite reciprocals.

A( 3 , 5 )

B( - 2 , 7 )

$m_{AB}$ = $\frac{7-5}{-2-3}$ = - $\frac{2}{5}$

C( 10 , 5 )

D( 6 , 15 )

$m_{CD}$ = $\frac{15-5}{6-10}$ = - $\frac{5}{2}$

Plz help!! Will give 30 points!!

Inessa [10]

Answer:

B) 12

Step-by-step explanation:

C is the circumference, d is the diameter, and r is the radius. They are related by the following equations:

d = 2r

C = πd = 2πr

If d = 6.0, then r = 3.0.

If C / C' = 0.25, then:

(2πr) / (2πr') = 0.25

r / r' = 0.25

3 / r' = 0.25

r' = 12
