Answer:

y -10 = 1/8(x +8)

Step-by-step explanation:

The point-slope form of the equation of a line with slope m through point (h, k) is ...

y -k = m(x -h)

You have m = 1/8, and (h, k) = (-8, 10).

Putting those numbers in the form gives ...

y -10 = 1/8(x -(-8))

You can simplify the double minus sign so you have ...

y -10 = 1/8(x +8)

A lot of math is about matching patterns and making substitutions. This is a good example of that.

An Uber fare in Columbus is $3.50 for the first ½ mile and additional mileage charged at a rate of $0.30 for each additional 0.1

Verizon [17]

Answer:

$\frac{11}{3}$ miles

Step-by-step explanation:

Let the total miles traveled be x.

Now, for the first 0.5 miles total charge is = $3.50

Then, the remaining distance to be traveled $=(x-0.5)$ miles

For each additional 0.1 mile, the additional charge is $0.30

So, for $(x-0.5)$ miles, the total additional charge will be $=\frac{0.3}{0.1}(x-0.5) =3(x-0.5)$

Then, including the $2 tip, the total fare will be $=3.50+3(x-0.5)+2$

Now, given that total fare is $15, so,

$3.50+3(x-0.5)+2=15\\3.50+3x-1.5+2=15\\3x+4=15\\3x=11\\x=\frac{11}{3}$ miles

Jeanne makes hair bows to sell at the craft fair. Each bow requires 1.5 yards of ribbon.At the fabric store, ribbon is sold by

Over [174]

1.5 yards of ribbon per bow
84 bows need to be made, so 1.5 x 84 = 126 yards

1 yard = 0.33 feet, so 126/0.33=381.8181 (ans must round up)

So Jeanne will need 382 feet of ribbon

A cylinder has a volume of 132x cubic feet and height of 4 feet. What is the area of the base?

Bogdan [553]

Answer:

33π square feet

Step-by-step explanation:

Volume = base area × height

132π = base area × 4

or, base area = 132π/4

or, base area = 33π

find an equation of the line that bisects the acute angle formed by the graphs of 3x+5y+2=0 and 5x+3y-2=0

Aleks [24]

Answer:

x+ y = 0

and

-2x + 5y + 2 = 0

Step-by-step explanation:

given line

3x+5y+2=0

5x+3y-2=0

solution

when two line bisect each other then line equation of bisector is express as

$\frac{|A1x+B1y+C1|}{\sqrt{A1^2+B1^2+C1^2}} = \frac{|A2x+B2y+C2|}{\sqrt{A2^2+B2^2+C2^2}}$ .........................1

and here

A1 = 3

B1 = 5

C1 = 2

and

A2 = 5

B2 = 3

C2 = -2

so now put value in equation 1 we get

$\frac{|3x+5y+2|}{\sqrt{3^2+5^2+2^2}} = \frac{|5x+3y-2|}{\sqrt{3^2+5^2+(-2)^2}}$

solve it we get

-2x + 5y + 2 = 0 ..........1

and

3x+5y+2 = - ( 5x+3y-2 )

solve it we get

8x + 8y = 0

x + y = 0 ................2
