#1

0.4

Additive=-0.4

Multiplicative=1/0.4

#2

5 5)6=35/6

  • Additive=-35/6
  • Multiplicative=6/35

#3

5x-3y-2x+3y=3x

  • Additive=-3x
  • Multiplicative=1/3x

#4

-11a-13b+7a-3b=-4a-16b

Additive

  • 4a+16b

Multiplicative

  • 1/(4a+16b)

#5

8x-7y-(3-6y)=8x-7y-3+6y=8x-y-3

Additive.

  • y-8x+3

Multiplicative

  • 1/(8x-y-3)

The expression is equivalent to the given expression is: negative 9 over 12 times t minus 2 over 9.

<h3>What is stated as the equivalent expression?</h3>
  • Equivalent expressions have been expressions that perform the same function despite their appearance.
  • If two linear algebra expressions are equivalent, they have the same value when the variable is set to the same value.

For the given question, the expression is stated as-

Negative 7 over 6 times t plus 4 over 9 end quantity minus expression quantity negative 5 over 12 times t plus 2 over 3 end quantity

This can be written as;

= -7t/6 + 4/9 - (-5t/ 12 + 2/3)

Simplify the expression as;

= -7t/6 + 4/9 + 5t/ 12 - 2/3

Re arrange the numbers

= -7t/6  + 5t/ 12 - 2/3 + 4/9

Combine the variables and constant separately.

= -9t/12 - 2/9

This can be written in words as- negative 9 over 12 times t minus 2 over 9.

Thus, the expression is equivalent to the given expression is: negative 9 over 12 times t minus 2 over 9.

How can you know if this equation is true? 1/2 + 3/8 = 4/10 = 2/5
romanna [79]

Answer:

<h2>2. Because 25<12, this equation can not be true.</h2>

Step-by-step explanation:

I just solved the equation and 1/2 + 3/8 = 7/8 or 87.5%.

4/10 equals 40%.

Since these two do not sync up, the equation must be false and 2 is the only answer saying the equation is false.

I'm always happy to help :)

consider the equation y = 8 - 3x. for every increase of 1 in the x- variable, what is the change in the y- variable?. a) increas
Lubov Fominskaja [6]

The change in the y-variable would be decrease of 3. The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query about and it will be able to help you.

A pair of equations is shown below:
horrorfan [7]

Answer:

A. x=2, y = 7.

B. (2, 7).

Step-by-step explanation:

A. You can eliminate y by subtracting the equations:

y =  8x - 9

y =  4x - 1       Subtract:

0 =  4x - 8

4x = 8

x = 8/4 = 2.

Now substitute for x in the first equation:

y = 8(2) - 9 = 7.

Check in the second equation:

y = 4x - 1

7 = 4(2) - 1 = 7.  Check is OK.

B. On the graph they will intersect at the point (2, 7).

They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.
