Answer: c) 0.6

Step-by-step explanation:

0 is not a success so that value is not included.

1 and 2 are successes so those values are added:

0.48 + 0.16 = 0.64

Rounded to the nearest tenth is: 0.6

Domain and range of (4,-4),(2,-3),(-5,1),(4,-1)

aniked [119]

(x; y)

The domain is x.

The range is y.

Therefore

(4; -4) → x = 4; y = -4

(2;-3) → x = 2; y = -3

(-5; 1) → x = -5; y = 1

if is (-4; -1) not (4; -1) then

(-4; -1) → x = -4; y = -1

The DOMAIN = {-5; -4; 2; 4}

The RANGE = {-4; -3; -1; 1}

If is (4; -4) and (4; -1) then it is not a function.

Can someone assist me with this?

Mnenie [13.5K]

Answer:

29: 7

Step-by-step explanation:

$\frac{8}{3x - y} = \frac{5}{x + 3y}$

Cross multiply:

$8(x + 3y) = 5(3x - y)$

Expand bracket:

$8x + 24y = 15x - 5y$

Bring x terms to 1 side, y terms to the other:

$15x - 8x = 24y + 5y$

Simplify:

$7x = 29y$

Divide by 7 on both sides:

$x = \frac{29}{7} y$

Divide both sides by y:

$\frac{x}{y} = \frac{29}{7}$

∴ The ratio of x to y is 29:7.
