6 0

Answer:

Step-by-step explanation:

1). $-\frac{5}{12}$ x = 0 ⇒ x = 0

2). 5,4 ( x + 6,3 ) = 0 ⇒ x + 6,3 = 0 ⇒ x = - 6,3

3). ( x - 3 )( x + 4 ) = 0 ⇒ x - 3 = 0 или x + 4 = 0 ⇒ x = 3 или x = - 4

4). 23,5 | x | = 0 ⇒ | x | = 0 ⇒ x = 0

The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. The cost of one battery is

mixas84 [53]

Answer: The equation that represents the give situation is, y = 0.75 x + 12

Step-by-step explanation:

Here, x represents the number of batteries the child bought and y represents the total cost.

Since, the cost of one batteries = $ 0.75

⇒ The cost of x batteries = 0.75 x

The cost of one toy = $ 12

Hence, the total cost = The cost of one toy + The cost of x batteries

= y = 0.75 x + 12

Which is the required equation that represents the given situation.

Show that the two triangles ABC and DEF are congruent by the HL theorem.

inna [77]

Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.

The Hypotenuse-Leg theorem states that two right triangles are congruent if and only if their hypotenuses and any of their corresponding legs are congruent. That is to say:

$\overline {AC} \cong \overline {DF}$ , $\overline{BC} \cong \overline {EF}$

$AC = DF, BC = EF$

$\sqrt{AB^{2}+BC^{2}} = \sqrt{DE^{2}+EF^{2}}$ , $BC = EF$

If we know that $AB = 10$ , $BC = 4$ , $DE = 10$ and $EF = 4$ , then we have the following outcomes:

$\sqrt{10^{2}+4^{2}} = \sqrt{10^{2}+4^{2}}$

$4 = 4$

Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.
