What is the midpoint of AB?

Mathematics
1 answer:
barxatty [35]3 years ago
3 0

Answer:

The answer to your question is ( -\frac{1}{2} , \frac{1}{2} )

None of your answers, maybe the second one but you forgot that the numbers are fractions.

Step-by-step explanation:

Data

A (-3, 4)

B (2, -3)

Formula

Xm = \frac{x1 + x2}{2}

Ym = \frac{y1 + y2}{2}

Substitution

Xm = \frac{-3 + 2}{2}

Xm = - \frac{1}{2}

Ym = \frac{4 -3}{2}

Ym = \frac{1}{2}

Midpoint = ( -\frac{1}{2} , \frac{1}{2} )

5y+4x=10.51 8y+3x=10.39
Phoenix [80]

Answer:

  (x, y) = (1.89, 0.59)

Step-by-step explanation:

Written in general form, the equations are ...

  4x +5y -10.51 = 0

  3x +8y -10.39 = 0

These can be solved using the cross-multiplication method to find ...

  ∆1 = (4)(8) -(3)(5) = 17

  ∆2 = (5)(-10.39) -(8)(-10.51) = 32.13

  ∆3 = (-10.51)(3) -(-10.39)(4) = 10.03

Then the values of the variables are ...

  x = ∆2/∆1 = 32.13/17 = 1.89

  y = ∆3/∆1 = 10.03/17 = 0.59

The solution is (x, y) = (1.89, 0.59).

The function C(x) = 25.50x + 50 models the total cost for a cleaning company to clean a house, where x is the number of hours it
vodomira [7]

Answer:

<em>The average rate of change is $25.5 per hour, option B.</em>

Step-by-step explanation:

<u>Average Rate of Change </u>

When we are explicitly given some function C(x), we sometimes need to know the rate of change of C when x goes from x=x_1 to x=x_2. It can be computed as the slope of a line .

\displaystyle m=\frac{C(x_2)-C(x_1)}{x_2-x_1}

The provided function is

C(x)=25.50x + 50

We are required to compute the average rate of change between the points

x_1=3\ ,\ x_2=9

Let's compute

C(3)=25.50(3) + 50=126.5

C(9)=25.50(9) + 50=279.5

\displaystyle m=\frac{279.5-126.5}{9-3}

\displaystyle m=\frac{153}{6}=25.5

The average rate of change is $25.5 per hour, option B.
