1 answer:
Yuki888 [10]3 years ago
8 0

Answer:

Step-by-step explanation:

8x + 12y - 2z = -36

-5x + 3y + 2z = 15

3x + 15y = -21

3x + 2y - 4z = -24

-10x + 6y + 4z = 30

-7x + 8y = 6

3x + 15y = -21

-21x + 24y = 18

21x + 105y = -147

129y = -129

y = -1

4x - 6 - z = -18

4x - z = -12

3x - 2 - 4z = -24

3x - 4z = -22

4x - z = -12

3x - 4z = -22

-16x + 4z = 48

  3x - 4z = -22

-13x = 26

x = -2

-5(-2) + 3(-1) + 2z = 15

10 - 3 + 2z = 15

7 + 2z = 15

2z = 8

z = 4

x = -2, y = -1, z = 4

Find the equivalent expression 11(3p+5x)+4x-x
Alex777 [14]

Hello there! :)

<em><u>Answer:</u></em>

<em><u>=33p+58x</u></em>

<em><u>*The answer must have a positive sign.*</u></em>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, expanded form. Then you can also multiply from left too right.

11(3p+5x)=33p+55x

Next, rewrite the problem down.

33p+55x+4x-x

And finally, you add by the similar elements. Then you add by the numbers too.

55x+4x-x=58x

Final answer: → 33p+58x

Hope this helps!

Thanks!

Have a great day!

-Charlie

If you add five to twice a number the results is fifteen. What is the number?
bonufazy [111]

The number is 5.

Step-by-step explanation:

Let,

x represent the unknown number.

According to given statement;

add five to twice a number the results is fifteen

2x + 5 = 15

Subtracting 5 from both sides

2x+5-5=15-5\\2x=10

Dividing both sides by 2

\frac{2x}{2}=\frac{10}{2}\\x=5

The number is 5.

The graph shows a function f(x). Determine the
blsea [12.9K]

9514 1404 393

Answer:

  • f^-1(4) = 2
  • f^-1(-5) = -4
  • f^-1(0) = 0

Step-by-step explanation:

The inverse of the function y = f(x) is ...

  x = f^-1(y)

That is, to answer this question, you find the x-value that corresponds to the given y-value. The marked points are ...

  (-4, -5), (-2, -4), (0, 0), (2, 4), (4, 5)

Look for the values 4, -5, 0 as the second number of these ordered pairs, and report the first number of the pair.

  f^-1(4) = 2

  f^-1(-5) = -4

  f^-1(0) = 0
