Answer:

\boxed {\boxed {\sf (0,1)}}

Step-by-step explanation:

First, let's define the points.

The first point is right 4 and up 7. The second point is left -4 and down 5. Therefore, the points are (4 , 7) and (-4 , -5).

Next, use the midpoint formula to find the midpoint.

(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )

Since, the points are (4,7) and (-4,-5):

x_1=4\\y_1=7 \\x_2= -4 \\y_2= -5

Substitute the points into the formula.

(\frac{4+-4}{2}, \frac{-5+7}{2}  )

Solve the numerators first.

(\frac{0}{2} , \frac {2}{2})

Divide.

(0,1)

The midpoint of the two points is <u>(0,1)</u>

PLEASE HELP ME, I HAVE BEEN WAITING FOR A DAAYY!! How old am i if 400 reduced by 3 times my age is 244?
Vlad1618 [11]

Answer:

52 years

Step-by-step explanation:

Let

Your age = x

3 times your age = 3 * x

= 3x

The equation can be written as:

400 - 3x = 244

400 - 244 = 3x

156 = 3x

Divide both sides by 3

x = 156/3

x = 52

Therefore,

Your age is 52 years

Answer:

x = 39/74 - sqrt(1817)/74 or x = 39/74 + sqrt(1817)/74

Step-by-step explanation:

Solve for x:

(x - 4) (3 x - 2) - ((6 - 5 x) (x - 4) (8 x - 1))/(4 - x) = 0

Simplify and substitute y = 4 - x.

(x - 4) (3 x - 2) - ((6 - 5 x) (x - 4) (8 x - 1))/(4 - x) = -434 + 257 (4 - x) - 37 (4 - x)^2

= -37 y^2 + 257 y - 434:

-37 y^2 + 257 y - 434 = 0

Divide both sides by -37:

y^2 - (257 y)/37 + 434/37 = 0

Subtract 434/37 from both sides:

y^2 - (257 y)/37 = -434/37

Add 66049/5476 to both sides:

y^2 - (257 y)/37 + 66049/5476 = 1817/5476

Write the left hand side as a square:

(y - 257/74)^2 = 1817/5476

Take the square root of both sides:

y - 257/74 = sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74

Add 257/74 to both sides:

y = 257/74 + sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74

Substitute back for y = 4 - x:

4 - x = 257/74 + sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74

Subtract 4 from both sides:

-x = sqrt(1817)/74 - 39/74 or y - 257/74 = -sqrt(1817)/74

Multiply both sides by -1:

x = 39/74 - sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74

Add 257/74 to both sides:

x = 39/74 - sqrt(1817)/74 or y = 257/74 - sqrt(1817)/74

Substitute back for y = 4 - x:

x = 39/74 - sqrt(1817)/74 or 4 - x = 257/74 - sqrt(1817)/74

Subtract 4 from both sides:

x = 39/74 - sqrt(1817)/74 or -x = -39/74 - sqrt(1817)/74

Multiply both sides by -1:

Answer:  x = 39/74 - sqrt(1817)/74 or x = 39/74 + sqrt(1817)/74

kkurt [141]

Answer:

1.003 * 10^8

Step-by-step explanation:

Given that :

The United States has about 100,300,000 registered to use cellular phones in the year 2000

100,300,000 in scientific notation:

(100,000,000) + (300,000)

(1 * 10^8) + (3 * 10^5)

To ensure equal power :

300,000 = 3 * 10^5 = 0.003 * 10^8

Hence,

(1 * 10^8) + (0.003 * 10^8)

(1 + 0.003) * 10^8

1.003 * 10^8
