Which corresponds to the perimeter of triangle ABC?

Mathematics
1 answer:
____ [38]3 years ago
4 0

Answer:

The answer to your question is: letter C

Step-by-step explanation:

Data

A (-5 , -1)

B (-2, 3)

C (6, -3)

Perimeter = ?

Formula

d = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }

distance AB      d = \sqrt{(-2 + 5)^{2} + (3 + 1)^{2} }

                         d = \sqrt{(3)^{2} + (4)^{2} }

                         d = \sqrt{(9 + (16) }

                                 d = \sqrt{25}

                                        d = 5

Distance BC    d = \sqrt{(-3 - 3)^{2} + (6 + 2)^{2} }

                         d = \sqrt{(-6)^{2} + (8)^{2} }

                         d = \sqrt{36 + 64}                    

                         d = \sqrt{100}

                                d = 10

Distance AC     d = \sqrt{(-3 + 1)^{2} + (6 + 5)^{2} }

                         d = \sqrt{(-2)^{2} + (11)^{2} }

                         d = \sqrt{4 + 121}

                         d = \sqrt{125}

                                d = 11.2

Perimeter = 5 + 10 + 11.2

                = 15 + \sqrt{125}

The expression is equivalent to the given expression is: negative 9 over 12 times t minus 2 over 9.

<h3>What is stated as the equivalent expression?</h3>
  • Equivalent expressions have been expressions that perform the same function despite their appearance.
  • If two linear algebra expressions are equivalent, they have the same value when the variable is set to the same value.

For the given question, the expression is stated as-

Negative 7 over 6 times t plus 4 over 9 end quantity minus expression quantity negative 5 over 12 times t plus 2 over 3 end quantity

This can be written as;

= -7t/6 + 4/9 - (-5t/ 12 + 2/3)

Simplify the expression as;

= -7t/6 + 4/9 + 5t/ 12 - 2/3

Re arrange the numbers

= -7t/6  + 5t/ 12 - 2/3 + 4/9

Combine the variables and constant separately.

= -9t/12 - 2/9

This can be written in words as- negative 9 over 12 times t minus 2 over 9.

Thus, the expression is equivalent to the given expression is: negative 9 over 12 times t minus 2 over 9.

Linda purchased a used vehicle that depreciates under a straight line method. The initial value of the car is $7000, and the sal
makvit [3.9K]

Answer:

The value at the end of year 2 is $4400.

Step-by-step explanation:

The best approach here is to determine the expression for the line depreciation and then calculate the depreciation value at x = 2 years.

A line is given by

y = mx + b

where m is the slope and b the bias (aka y-intercept).  You can determine both directly from what is given. The slope is change in y divided by change in x. We know that over 5 years the car loses (500-7000)=-6500 in value. So, the slope is m=-6500/5 (note the negative sign). At time 0, the y-intercept is 7000, since that is the initial value (at year 0). So our line function is fully identified:

y = -\frac{6500}{5}x+7000

and gives you the value of the car in any given year. To answer the question, we now plug in 2 as value of x:

y=-\frac{6500}{5}\cdot 2 + 7000= 4400

Which of the following shows the correct solution steps and solution to 7x- 4 = -182 7x - 4 = -18 71 - 4+4= -18 + 4 72 = -14 A.
erica [24]

Answer/Step-by-step explanation:

7x- 4 = -182

<em>Step:</em>

Add 4 to both sides

7x - 4 + 4 = -182 + 4

Simplify

7x = -178

Divide both sides by 7

7x/7 = -178/7

Simplify

x = -178/7

Decimal form = -25.4285714286
