Answer 1

Answer:  28

Step-by-step explanation:

Let x represent the digit in the tens place and y represent the digit in the ones place.     xy → 10x + y

The square of the sum of the digits is 100.

EQ1: (x + y)² = 100       →    x + y = 10

2 is subtracted from 3 times the number is the digits reversed.

EQ2: 3(10x + y) - 2 = 10y + x    →   30x + 3y - 2 = 10y + x      →     29x - 7y = 2

Solve the system of equations using the Elimination method:

EQ1:      x +  y = 10    →  7(x + y = 10)     →      7x + 7y = 70

EQ2: 29x - 7y = 2     →  1(29x - 7y = 2  →   29x - 7y =  2    

                                                                    36x        = 72

                                                                 ÷36         ÷36  

                                                                            x = 2

Substitute x = 2 into either of the equations to solve for y.:

EQ1: x + y = 10

       2 + y = 10

            y = 8

The digit is: 28

Solve for x.

Answers

Answer:

Step-by-step explanation:

Let's solve for a.

ax+3=6

Step 1: Add -3 to both sides.

ax+3+−3=6+−3

ax=3

Step 2: Divide both sides by x.

ax /x = 3 /x

a= 3 /x

Answer:

a= 3 /x

 

Answer:

ax = 3

Step-by-step explanation:

ax + 3 = 6

Subtract 3 from both sides of the equation

ax = 3

Find the slope of the line passing through each of the following pairs of points.
(0, -8), (0,4)

Answers

Answer:

The slope is undefined

Step-by-step explanation:

You can find the slope by doing change in y/change in x.

Y changed by 12 units while x changed by 0.

12/0 is undefined, so the slope is as well (on a graph, the line would be vertical)

0 or undefined or infinity

Step by step explanation:

slope = y2 - y1 / x2 - x1

= 4 + 8 / 0 + 0

= 12 / 0

= 0

Bastian was able to map triangle ABC onto triangle A'B'C' using a reflection, rotation, and a dilation. Then Bastian concluded that he was able to map triangle ABC onto triangle A'B'C' using a sequence of rigid transformations and dilations, so the triangles are similar. What error did Bastian make in his conclusion?

Bastian used a rotation, so the triangles aren't similar.

Bastian used a combination of similarity transformations, which can produce a non-similar result.

There is no error. This is a correct conclusion.

Bastian used a dilation, which does not preserve similarity.

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)

The ∠BAC is 58° and ∠CAD is 32° for the given figure.

What is an angle?

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Given,

∠BAD = 90°

Since,

∠BAD =  ∠BAC + ∠CAD

15x - 2 + 7x + 4 = 90°

22x = 88 ⇒ x = 4

So,

∠BAC = 15(4) - 2 = 58°

And

∠CAD = 7(4) + 4 = 32°

Hence "The ∠BAC is 58° and ∠CAD is 32° for the given figure".

Answers

Answer:

59 patients

Step-by-step explanation:

Total patients Sam saw in a week = 236

Percentage of patients near-sighted = 25%

How many of the patients Sam saw were near-sighted?

Number of patients near-sighted = 25% of 236

= 25/100 × 236

= 0.25 × 236

= 59

Number of patients near-sighted = 59 patients

The number of patients Sam saw in a week that were near-sighted is 59 patients

Answers

Answer:

Check Graph below

Step-by-step explanation:

y > -22 + 6x + 3

Add -22 and 3.

y > 6x - 19

Use the slope-intercept form to find the slope and y-intercept.

Slope: 6

y-intercept: (0,-19)

Graph a dashed line, then shade the area above the boundary line since y is greater than 6x − 19 .

y > 6x - 19

What are the coefficients for the binomial expansion of (p + q)6?

1, 5, 10, 10, 5, 1
1, 4, 6, 4, 1

Answers

Answer:

1, 6, 15, 20, 15, 6, 1

Step-by-step explanation:

The binomial expansion of (p + q)⁶ gives 1, 6, 15, 20, 15, 6, 1.

There is always one more extra term for each power;

    (p + q)⁰  =                                      1

    (p + q)¹ =                                   1         1

    (p + q)² =                             1         2           1

    (p + q)³ =                         1         3          3           1

    (p + q)⁴ =                   1          4          6          4             1

    (p + q)⁵ =             1          5          10         10         5              1

   (p + q)⁶ =          1        6           15         20        15            6             1

The above is a paschal triangle and which shows the coefficients of the expanded terms to their power.
