What are the coordinates for the x and y intercepts of the function 4y - 2x = 24?

Alexeev081 [22]

First, let's put this in Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
4y - 2x = 24 Add 2x to both sides
4y = 2x + 24 Divide both sides by 4
y = (1/2)x + 6
Now that we're in slope-intercept we can easily find the y and x intercepts/
b = 6, so the y-intercept equals 6. Plug zero in for x to confirm!

Now we plug 0 in for y to find the x intercept:
0 = (1/2)x + 6 Subtract 6 from both sides
-6 = (1/2) x Multiply both sides by 2
-12 = x
The x intercept is -12

In Conlusion:
x-intercept = -12
y- intercept = 6

Factorise : x³ + x - 3x² -3

ANEK [815]

Answer:

(x²+1)(x-3)

Step-by-step explanation:

Factorize x³ + x - 3x² -3

x³-3x²+x-3

Factorize

x²(x-3)+1(x-3)

= (x²+1)(x-3)

Hence the factorized form is (x²+1)(x-3)

when Best Buy sells a Samsung 32" flat screen television for $219.99, does the 32" represent the length, width, or diagonal of t

Varvara68 [4.7K]

Answer:

Diagonal

Step-by-step explanation:

The measure of a television is always indicated by providing the length of the diagonal, in inches.

In fact, the actual length and height of a 32" tv are:

- Length:

L = 27.9 inches

- Height:

h = 15.7 inches

For an object with a rectangular shape, such as the TV, the diagonal of the object can be found by using Pythagorean's theorem:

$d=\sqrt{L^2+h^2}$

where

L is the length of the rectangle

h is the height of the rectangle

Substituting the values above, we find:

$d=\sqrt{(27.9)^2+(15.7)^2}=32.0 in.$

Which corresponds to the diagonal of the TV.
