Answer:

y - 10 = 2(x - 4)

Step-by-step explanation:

Recall this:  The slope of a new line perpendicular to a given line is the negative reciprocal of the slope of the given line.

Thus:  The slope of the new line is the negative reciprocal of (-1/2), or +2.

Using the point-slope formula for the equation of a line,

y - k = m(x - h)

becomes

y - 10 = 2(x - 4)

This could also be written as y = 2x - 8 + 10, or y = 2x + 2

Find the price per unit for each item, then choose the best buy. a. Cereal, 10 oz. box for $5.90 would b. Cereal, 24 oz. box for
Taya2010 [7]

Cereal A

10 ounces = $5.90

10/10 ounces = $5.90/10 .... divide both sides by 10

1 ounce = $0.59

1 ounce = 59 cents

----------

Cereal B

24 ounces = $6.48

24/24 ounces = $6.48/24  .... divide both sides by 24

1 ounce = $0.27

1 ounce = 27 cents

We see that Cereal B is the cheaper deal per ounce

---------

<h3>Answer: Cereal B is the better deal</h3>

I need help answering these questions for geometry :)

The answers to the question have been written below

<h3>The changes to a polygon</h3>

1. If the number of sides of the polygon should increase then the measure of the interior angle would increase by 180.

2. A regular polygon has the sum of its external angles as 360. This is solved as 360/n = 0

Hence the value of the exterior would move towards 0 as its sides increases.

4. As the total sum of the of the polygon changes, it would tend towards infinity.

5. The total sum of the exterior angles as the number of sides changes would tends towards 360 degrees.

Is (-3,2)(−3,2)left parenthesis, minus, 3, comma, 2, right parenthesis a solution of -4x -10y &lt; -9−4x−10y&lt;−9minus, 4, x, m
r-ruslan [8.4K]

Answer:

The answer to your question is The point (-3, 2) is not a solution

Step-by-step explanation:

Inequality

                                   - 4x - 10y < - 9

-point (-3, 2)

Process

1.- To solve this problem, just substitute the point in the inequality and simplify

a) Substitution

                                    -4(-3) - 10(2) < - 9

b) Simplification

                                    12 - 20 < - 9

c) Result

                                        - 8 < - 9

This is false, -8 > -9
