Answer:

x = -16

Step-by-step explanation:

$\frac{1}{4}x-6=-10 < ==add\ 6\ to\ both\ sides\\ \ \ \ \ \ \ \ \ +6 \ \ \ \ \ \ \ \ +6\\\\\frac{1}{4}x=-4 < ==multiply\ both\ sides\ by\ 4\\4(\frac{1}{4}x=-4)\\\\x=-16 < ==final\ answer$

Hope this helps!

Answer:

The answer to your question is

Step-by-step explanation:

Data

4x - 8y = -16 ------------ (I)

x - 2y = - 8 ------------ (II)

a) Solve equation II for x

x = 2y - 8

Substitute x in equation I

4(2y - 8) - 8y = -16

8y - 32 - 8y = -16

8y - 8y = 32 - 16

0 = 16 The system has no solution because y was

cancelled.

b) When a system of equations do not have solution means that the lines are parallels and different.

KATRIN_1 [288]

The correct answer among the choices provided is the second option. Events A and B are dependent because P(A|B) P(B). And from conditional probability, we have P(A|B) = P(AintersectionB) / P(B).
Therefore, P (AintersectionB) is equal to P(A|B) × P(B).

-14(3a+6)=12(6-4a)+12 and steps please

Sunny_sXe [5.5K]

Answer:

In the given equation -14(3a+6)=12(6-4a)+12 the value of a is 28

Step-by-step explanation:

Given equation is -14(3a+6)=12(6-4a)+12

To simplify the given equation:

-14(3a+6)=12(6-4a)+12

Taking all terms to one side

-14(3a+6)-12(6-4a)-12=0

-[14(3a+6)+12(6-4a)+12]=0

Now dividing by negative sign on the above equation we get

14(3a+6)+12(6-4a)+12=0 (using distributive property)

42a+84+72-48a+12=0 ( adding the like terms )

-6a+168=0

-6a=-168

6a=168

$a=\frac{168}{6}$

Therefore a=28

Therefore in the given equation -14(3a+6)=12(6-4a)+12 the value of a is 28

A ball is dropped from the top of a building that is 250 feet tall. The

Virty [35]

-16t²+250 = 75

-16t² = 75 -250

-16t² = -175

t² = -175 /-16

t² = 175/16

Here there si two solutions : t = $\sqrt{175/16}$ and t = - $\sqrt{175/16}$

However, as time cannot rewind, we will keep only positive solution

So t = $\sqrt{175/16}$

in seconds it will be : 3.3 seconds
