Answer:

y = -1/2x + 5

Step-by-step explanation:

x + 2y = 10

Step 1: subtract x from both sides.

you will get: 2y = -x + 10

Step 2: get the y by itself, you can do this by dividing 2 by both sides.

= 2y = -x + 10

y = -1/2x +10/2

Then, 10/2 simplifies to 5.

So, your answer is: y = -1/2x + 5

Given h of x equals negative 2 times the square root of x minus 3 end root, which of the following statements describes h(x)?

Yuliya22 [10]

Using translation concepts, it is found that the correct option regarding the function is:

The function h(x) is decreasing on the interval (3, ∞).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent function is given by:

$f(x) = \sqrt{x}$

Which increases on (0, ∞).

The translated function is given by:

$g(x) = -2\sqrt{x - 3}$

With the translation, the domain is now (-3, ∞), and the function is decreasing, hence the correct option is given by:

The function h(x) is decreasing on the interval (3, ∞).

Prepare 1500 ml of 5.0 M H2SO4 from a stock H2SO4 which is 80% pure and a s.g of 1.018

pentagon [3]

To solve this we use the equation,

M1V1 = M2V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

M1 = .80 g H2SO4 / g solution (1018 g solution / L solution ) (1 mol / 98.08) = 8.30 M

8.30 (V1) = (5.0 M) (1.5 L)

V1 = 0.9036 L or 903.6 mL of the stock needed

y=−8x−3 x+y=7 Is (3,4)(3,4)left parenthesis, 3, comma, 4, right parenthesis a solution of the system? Choose 1 answer: Choos

kirill [66]

Given:

The system of equation is

$y=-8x-3$

$x+y=7$

To find:

Whether (3,4) is a solution of the given system or not.

Solution:

We have,

$y=-8x-3$ ...(i)

$x+y=7$ ...(ii)

Putting the value of y in (ii) from (i), we get

$x+(-8x-3)=7$

$x-8x-3=7$

$-7x=7+3$

$-7x=10$

Divide both sides by -7.

$x=\dfrac{10}{-7}$

$x=-\dfrac{10}{7}$

Putting $x=-\dfrac{10}{7}$ in (i), we get

$y=-8\times (\dfrac{-10}{7})-3$

$y=\dfrac{80}{7}-3$

$y=\dfrac{80-21}{7}$

$y=\dfrac{59}{7}$

So, the only solution of the given system is $\left(-\dfrac{10}{7},\dfrac{59}{7}\right)$ .

Hence, (3,4) cannot be a solution of given system, Hence the correct option is B.
