The sum of the digits of a three digit number is 19. The second digit is one more than the first digit. The third
Oxana [17]

Answer:

  • D. 568

Step-by-step explanation:

Let the number is in the form of xyz

<h3>We have</h3>

Sum of the digits is 19

  • x + y + z = 19

The second digit is one more than the first digit

  • y = x + 1

The third digit is two more than the second digit

  • z = y + 2 = x + 1 + 2 = x + 3

<u>Substitute the values of y and z</u> into the first equation and solve for x

  • x + x + 1 + x + 3 = 19
  • 3x + 4 = 19
  • 3x = 15
  • x = 5

<u>Find the value of y and z</u>

  • y = 5 + 1 = 6
  • z = 5 + 3 = 8

The number is 568

Complete the table to investigate dilations of exponential functions.
Zinaida [17]

Answer:

a = 1

b = 3

c = 1

d = 2

e = 6

f = 8

Step-by-step explanation:

Any integer with power as zero = 1

<h3>For a</h3>

2^x

2^0

= 1

<h3>For b</h3>

3 * 2^x

3 * 2^0

3 * 1

= 3

<h3>For c</h3>

2 ^ 3(x)

2 ^ 3(0)

2 ^ 0

= 1

<h3>For d</h3>

2^1

= 2

<h3>For e</h3>

3 * 2^x

3 * 2^1

3 * 2

= 6

<h3>For f</h3>

2 ^ 3(x)

2 ^ 3(1)

2 ^ 3

2 * 2 * 2

= 8

enot [183]

Answer:

a. These points’ vertical distance from the origin is twice their horizontal distance.

both coordinates positive A(2,4)

both coordinates negative B (-2,-4)

opposite signs case 1:  C (2,-4)

opposite signs case 2: D (-2,4)

b. These points’ horizontal distance from the origin is two units more than the vertical distance

both coordinates positive A(4,2)

both coordinates negative B (-4,-2)

opposite signs case 1:  C (4,-2)

opposite signs case 2: D (-4,2)

c. These points’ horizontal and vertical distances from the origin are equal, but only one coordinate is positive.

Case 1 x coordinate negative

A (-5,5)

Case 2 y coordinate negative

Do all perpendicular lines have negative reciprocal slopes?
inna [77]

Not necessarily, the more correct definition is opposite reciprocal slopes.

The example used is how horizontal and vertical lines are parallel. Horizontal lines have a slope of 0, also written as 0/1. However, vertical lines have an undefined slope, which isn't necessarily negative. It has a slope of 1/0, which is undefined. In this case, the reciprocal isn't negative.

In all other cases (1 and -1, 2 and -1/2, etc.) yes, the perpendicular pairs are negative and reciprocal.

Bingel [31]

Answer:

57

Step-by-step explanation:

( 27 + 19 + 41 + 51 + 29 + 35 + k ) / 7 = 37

202 + k = 37 x 7

202 + k = 259

k = 259 - 202

k = 57
