What are the x-intercept and y-intercept of the graph of y=−12x+4y=−12x+4 ?

1 answer:

6 0

The x-intercept is the value of x when y is equal is zero. It is the point in the x-axis intersected by the line. The y-intercept is the value of y when x is zero. It is where the line intersects in the axis. Therefore, for the given equation:

y=−12x+4

y=−12(0)+4 = 4<--------y-intercept

0=−12x+4
x = 1/3 <--------x-intercept

The diagram shows a sector of a circle radius 10cm

Yuki888 [10]

Answer:

$\text{Perimeter of sector = 43.6 (Rounded to the nearest tenth.)}$

Step-by-step explanation:

$\text{Perimeter of the sector = Radius + arc length + radius}$

$\text{Radius = 10 cm}$

$\text{Perimeter of the sector = 10 + arc length + 10 }$

$\text{Perimeter of the sector = 20 + arc length }$

$\text{arc length = (sector angle/ 360 ) * perimeter of the circle}$

$\text{Perimeter of a circle }=2\pi r$

$\text{sector angle} = 135$

$\text{arc length} = (135/ 360 ) * 2\pi (10)$

$= (3/8) 20\pi$

$= 15\pi /2$

$\text{Using }\pi =3.14$

$= 15 * 3.14 /2$

$= 23.55$

$\text{Perimeter of the sector = 20 + 23.55}$

$= 43.55$

$= 43.6 cm$

$\text{perimeter of the sector = 43.6 cm }$

They each get 14 cents,
A quarter = 25c
A nickel = 5c
A dime = 10c
2 pennies = 2c

25 + 5 + 10 + 2 = 42c

42 divided by 3 is 14 cents
So Willie, Donald and Maya get 14 cents each

What is the answer to 2/5(10p-15)=14?

satela [25.4K]

Answer:

P = 5

Step-by-step explanation:

2/5(10p) - 2/5(15)= 14

20p/5 - 30/5= 14

4p - 6= 14

4p = 20

p=5

Assigned newbits with the opposite values of oldbits if flipbits is true. ex: if oldbits = [1, 1, 0, 1] and flipbits is 1, then

Kisachek [45]

Franck's answer is better (using ~), but I just wanted to point out that the conditional in yours is slightly redundant. It's easy to forget that, since you already have a boolean value, you don't need to perform a comparison in your conditional. So you could have just done this...

if x x = false; else x = true; end
