Answer:

Step-by-step explanation:

Given :

$x + 10 = 4x - 2$

To Find : Value of x .

Solution :

⇒ $x + 10 = 4x - 2$

Taking from left to right and -2 from right to left . Then equation becomes:

⇒ $10+2 = 4x -x$

⇒ $12 = 3x$

⇒ $x= \frac{12}{3}$

⇒ $x= 4$

Hence , The value of x is 4

Answer:

4=x

Step-by-step explanation:

x+10= 4x-2

Subtract x from each side

x-x+10 = 4x-x-2

10 =3x-2

Add 2 to each side

10+2 = 3x-2+2

12 = 3x

Divide by 3

12/3 = 3x/3

4 = x

PLZ HELP ASAP DIVIDE LINE SEGMENTS

A (4,8) and b (7,2) and let c (x,y)

A , B and C are col-linear ⇒⇒⇒ ∴ slope of AB = slope of BC
slope of AB = (2-8)/(7-4) = -2
slope of BC = (y-2)/(x-7)
∴ (y-2)/(x-7) = -2
∴ (y-2) = -2 (x-7) ⇒⇒⇒ equation (1)

The distance between two points (x₁,y₁),(x₂,y₂) = d
$d = \sqrt{ (x2-x1)^{2} + (y2-y1)^{2} }$

The ratio of AB : BC = 3:2
AB/BC = 3/2
∴ 2 AB = 3 BC
$2 * \sqrt{ (7-4)^{2} + (2-8)^{2} }$ = $3* \sqrt{ (x-7)^{2} +(y-2)^{2} }$
eliminating the roots by squaring the two side and simplifying the equation
∴ 4 * 45 = (x-7)² + (y-2)² ⇒⇒⇒ equation (2)
substitute by (y-2) from equation (1) at equation (2)
4 * 45 = 5 (x-7)²
solve for x
∴ x = 9 or x = 5
∴ y = -2 or y = 6

The point will be (9,-2) or (5,6)
the point (5,6) will be rejected because it is between A and B

So, the point C = (9,-2)

Start time 2:15 a.m elapsed time 45 minutes

Ronch [10]

Answer:

It would be 3:00 am.

Step-by-step explanation:

Start time is given = 2:15 a.m

elapsed time = 45 minutes

After 45 minutes of start time, time is = 02:15 + 00:45

= 03:00 am.

After 45 minutes elapsed time, the time would be 3:00 am.

What is the amount of sales tax owed on a $350 laptop computer if the tax rate is 6%

valentinak56 [21]

What we need to do with this problem is multiply the amount the computer costs ($350) by the tax rate (6%). To do this, we first need to convert the percentage to a decimal, so we divide the 6 given by 100, leaving us with .06. Next, we need to multiply the $350 by the .06, giving us $21 as the amount we should be paying for sales tax. So your answer should be 2) $21.00!

Ahh yes, negative exponents always give us a scare once and a while. All the negative means is to flip the position of its base. For instance, if x has a negative exponent and x in the denominator, all you would have to do is move x to the numerator with the same power (except it's no longer negative). Before we substitute x and all the other variables which the values given, let's eliminate the negatives first.

After flipping positions/eliminating the negative exponents it should look like this:

$\frac{ 2^{2} x^{3} }{ y^{5} }$
which simplifies to
$\frac{ 4 x^{3} }{ y^{5} }$
now that everything is simplified, and all negative exponents are eliminated we can substitute x with 2, and y with (-4).
$\frac{4 (2)^{3} }{ (-4)^{5} }$
which simplifies to
$\frac{4(8)}{(-1024)} = \frac{32}{-1024} = - \frac{1}{32}$

Final Answer: - \frac{1}{32} [/tex]
