The line passes through (9,8) and is perpendicular to x-2y=-16

pickupchik [31]

The equation of line perpendicular to x-2y=-16 passing through (9,8) is: y=-2x+26

Step-by-step explanation:

Given

$x-2y=-16\\Adding\ 2y\ on\ both\ sides\\x=2y-16\\Adding\ 16\ on\ both\ sides\\x+16=2y-16+16\\x+16=2y\\2y=x+16\\Dividing\ both\ sides\ by\ 2\\\frac{2y}{2}=\frac{x+16}{2}\\y=\frac{x}{2}+\frac{16}{2}\\y=\frac{1}{2}x+8\\$

The equation is in slope-intercept form, the coefficient of x will be the slope of given line. The slope is: 1/2

As the product of slopes of two perpendicular lines is -1.

$\frac{1}{2}*m=-1\\m=-1*\frac{2}{1}\\m=-2$

Slope intercept form is:

$y=mx+b$

Putting the value of slope

y=-2x+b

To find the value of b, putting (9,8) in the equation

$8=-2(9)+b\\8=-18+b\\b=8+18\\b=26$

Putting the values of b and m

$y=-2x+26$

Hence,

The equation of line perpendicular to x-2y=-16 passing through (9,8) is: y=-2x+26

I need help with this Alice question.

Allisa [31]

Let x be the number of miles EXCLUDING the first
Amount of money paid (excluding the first : $(0.1).x
Total money paid (INCLUDING the 1st mile):
0.90 + (0.1)x = $3.2
0.1.x = 3.2 -0.90
0.1.x = 2.3
x = 2.3/0.1 = 23 miles
Now we have to add the 1st mile, then the total of miles = 23+1 = 24 Miles

Helga [31]

Answer:11.5cm, 23cm, 34.5 cm, 69cm

Step-by-step explanation:

1+2+3+6=12

138/12=11.5

First side=11.5cm

Second side=11.5x2=23cm

Third side=11.5x3=34.5cm

Fourth side=11.5x6=69cm
