Answer:

41.

No, Amits reasoning is not correct. The problem used to represent the equation, (-5.75) × 7, was solved incorrectly. (-5.75) × 7 = (-40.25). We know this because a negative number times a positive number is always a negative number. So the correct answer for the change in Amits bank account is -40.25

47.

a- Ivan's expression: $4.25 + $1.25(m)

Vicky's expression: $5.75 + $0.75(m)

b- $4.25 + $1.25(m) + $5.75 + $0.75(m)

<em>[</em><em>add</em><em> </em><em>$</em><em>4.25</em><em> </em><em>+</em><em> </em><em>$</em><em>5.75</em><em>]</em>

$10.00 + $1.25(m) + $0.75(m)

<em>[</em><em>add</em><em> </em><em>$</em><em>1.25</em><em>(</em><em>m</em><em>)</em><em> </em><em>+</em><em> </em><em>$</em><em>0.7</em><em>5</em><em>(</em><em>m</em><em>)</em><em>]</em>

<em> </em><em> </em><em> </em><em> </em>$10.00 + $2.00(m)

c- $10.00 + $2.00(m)

d- $10.00 + $2.00(m)

<em>[</em><em>2</em><em> </em><em>÷</em><em> </em><em>2</em><em> </em><em>=</em><em> </em><em>1</em><em>]</em><em> </em><em> </em>

<em>[</em><em>1</em><em>0</em><em> </em><em>÷</em><em> </em><em>2</em><em> </em><em>=</em><em> </em><em>5</em><em>]</em>

e- 2(m + 5)

That’s a tricky stem and leaf plot, Anw as the key shows 11|6 =16

So the most common arm span is 12 the least commons are 11,17,19,22 which appear only one time. So I’d say there are no outliers

Circle A has center (0, 0) and radius 3. Circle B has center (-5, 0) and radius 1. What sequence of transformations could be use
Dmitrij [34]

A translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) with a scale factor of 1 / 3 are necessary to transform circle A into circle B. (Correct choice: D)

<h3>What sequence of rigid transformations can be done on a circle</h3>

In this problem we must determine the sequence of transformations require to transform circle A into circle B. From analytical geometry we know that the equation of the circle in standard form is:

(x - h)² + (y - k)² = r²

Where:

  • (h, k) - Coordinates of the center.
  • r - Radius of the circle.

Then, we need to apply the following rigid transformations:

Translation

f(x, y) → f(x - h, y - k), where (h, k) is the translation vector.

Dilation with center at the center of the circle

r → k · r, where k is the scale factor.

The circle A is represented by x² + y² = 3, then we derive the expression for the circle B:

f(x, y) → f(x + 5, y - 2)

(x + 5)² + (y - 2)² = 9

r → k · r

(x + 5)² + (y - 2)² = (1 / 3)² · 9

(x + 5)² + (y - 2)² = 1

Then, a translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) are necessary to transform circle A into circle B.

The equation that represents the canned goods order is 24x+64y=384
Lubov Fominskaja [6]

The x-intercept is (16, 0) and y- intercept is (0, 6).

<h3>What is intercept?</h3>

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

Given: 24x+64y=384

For y- intercept, put x=0

Then,

24*0+64y=384

64y= 384

y= 6

Now, for x- intercept put y=0

Then,

24x+64*0=384

24x= 384

x= 15

Hence, the x-intercept is (16, 0) and y- intercept is (0, 6).
