Find the value of y, given that m_ KLM = 137º.
Musya8 [376]

Answer:

y ≈ 5.63

Step-by-step explanation:

m∠KLN and m∠NLM have to add up to m∠KLM

m∠KLN = 47°

m∠NLM = 16y°

m∠KLM = 137°

47 + 16y = 137

16y = 90

y = 45/8

y = 5.625

y ≈ 5.63

Two brothers are saving money to buy tickets to a concert. their combined saving is $55 one brother has $15 more than the other.
Vladimir [108]

Brother one: x

Brother two: x + 15

---

Make them add up to 55 in an equation.

x + (x + 15) = 55

Combine like terms.

2x + 15 = 55

Subtract 15 from both sides.

2x = 40

Divide both sides by 2.

x = 20

Plug 20 for x into brother two.

(20) + 15 = 35

Brother one has saved $20, brother two has saved $35.

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, ∞).

The formula for volume is Length x Width x Height.

So when you apply this formula to these questions the answers should be:

#7. 3x4x2 = 24

#8. 2x4x1 = 8

#9. 3x4x2 = 24

#10. 4x3x1 = 12

I hope this helps!
