How would you choose to reduce the system shown to a 2 × 2? Explain why you would choose this approach.

Answers

Answer 1

Answer:

hello the system related to your question is missing below is the system

–3x + y – 2z = 10 --------(1)

5x – 2y – 2z = 12 -------- (2)

x – y + z = 23  ----------- (3)

answer :

To reduce the system above to  a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires  X and either Y or Z

Step-by-step explanation:

Given system :

–3x + y – 2z = 10 --------(1)

5x – 2y – 2z = 12 -------- (2)

x – y + z = 23  ----------- (3)

To reduce the system above to  a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires  X and either Y or Z

Eliminating X is not the best way

solving equation 1 and 2

substrate equation (1 ) from equation (2) to eliminate Z

= 8x - 3y = 2

multiply equation (3) by 2 then substrate equation (2) from (3) to eliminate Y

2x - 2y + 2z = 46

-( 5x - 2y - 2z )=  12

= -3x + 4z = 34

Solve for b. 5b + 8 - 2b = 7b. A 2 B.4/5 C.4/7 D.1/2​

Answers

Answer:

b=2

Step-by-step explanation:

5b + 8 - 2b = 7b

Combine like terms

3b+8 = 7b

Subtract 3b from each side

3b+8-3b = 7b-3b

8 = 4b

Divide each side by 4

8/4 = 4b/4

2 =b

Answer:

b=2

Step-by-step explanation:

Simplifying

5b + 8 + -2b = 7b

Reorder the terms:

8 + 5b + -2b = 7b

Combine like terms: 5b + -2b = 3b

8 + 3b = 7b

Solving

8 + 3b = 7b

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '-7b' to each side of the equation.

8 + 3b + -7b = 7b + -7b

Combine like terms: 3b + -7b = -4b

8 + -4b = 7b + -7b

Combine like terms: 7b + -7b = 0

8 + -4b = 0

Add '-8' to each side of the equation.

8 + -8 + -4b = 0 + -8

Combine like terms: 8 + -8 = 0

0 + -4b = 0 + -8

-4b = 0 + -8

Combine like terms: 0 + -8 = -8

-4b = -8

Divide each side by '-4'.

b = 2

Simplifying

b = 2

and the tables represent two linear functions in a system
what solution to the system?

Answers

Answer:

The 'x' and 'y' values representing the solution of the system containing the two linear functions are;

x = -14, and y = -54

Step-by-step explanation:

From the given data table, we have;

The slope of the linear function on the left, 'm', is given as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

∴ m = (14 - (-22))/(3 - (-6)) = 4

Therefore, the equation in point and slope form we have;

y - 14 = 4·(x - 3)

y = 4·(x - 3) + 14

Similarly for the second linear function on the right, we have;

m = (-3 - (-30))/(3 - (-6)) = 3

Therefore, the equation in point and slope form we have;

y - (-3) = 3·(x - 3)

y = 3·(x - 3) - 3

Equating both 'y' values gives;

4·(x - 3) + 14 = 3·(x - 3) - 3

4·x + 2 = 3·x - 12

4·x - 3·x = x = -12 - 2 = -14

x = -14

y = 4·(x - 3) + 14 = 4 × (-14 - 3) + 14 = - 54

y = -54

Therefore, the solution of the system containing the two linear functions is x = -14, and y = -54

12) 180 - (180-62-51)

13) 360-100-60-95

1) all of them should add up to 180 so
65+75=140
180-140=40
F=40

2) finding x:
62+51=113
180-113= 67
X=67
We can know how much y equals from the two angles far away which we already calculated so y=113

C) all angles should add up to 360
100+95+60= 255
360-255=105
X=105

A roll of tape has a circumference of 14.8 centimeters. The circumference decreases 2.4 centimeters after you use some of the tape. What is the diameter of the roll after you use the tape? ROUND to the nearest HUNDREDTH. I need answers quick

Answers

Answer:

7.900 cm

Step-by-step explanation:

The computation of the diameter after using the tape is given below:

Since the circumference is 14.8 cm

And it would be decrease by 2.4 cm

So, the new circumference is

= 14.8 - 2.4

= 12.4 cm

Now the radius is

= 12.4 ÷ π

= 3.95

And, the diameter is

= 3.95 × 2

= 7.900 cm

The similar angle triangles are ΔQRS and ΔRQP , where the value of x = 6

What are similar triangles?

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be ΔQRS

Let the second triangle be ΔRQP

Now , the side QS is the common side

And , the measure of ∠QSQ = measure of RQP = 90°

So , the triangles are similar

And , corresponding sides of similar triangles are in the same ratio.

On simplifying , we get

The measure of side RS = 3

The measure of side SP = 9

So , the measure of side RP = 12

The measure of side QR = x

where RQ / RS = RP / RQ

x / 3 = 12 / x

Multiply by x on both sides , we get

x² / 3 = 12

Multiply by 3 on both sides , we get

x² = 6

Taking square roots on both sides , we get

x = 6

Therefore , the value of x is 6

Hence , the value of x from the similar triangles is 6
