Answer:

-5x-5

Step-by-step explanation:

original functions:

f(x)=3x-8\\g(x)=8x-3

Subtract the polynomials:

f(x)-g(x) = (3x-8) - (8x-3)

Distribute the negative sign:

3x-8-8x+3

Combine like terms:

(3x-8x)+(-8+3)

Add like terms:

-5x-5

What has to be true for the triangles to be congruent?
natita [175]

Answer:

Step-by-step explanation:

Argument

I think the answer is A = N or D. It that is true, then M = C because all three angles are equal which gives similarity. But there is a side involved. OM = CB. Therefore the two triangles are congruent by ASA

You have 20 coins in your pocket that are either quarter or dimes. They total $3.95. How many quarters do you have? A.16 B.13 C.
bekas [8.4K]

Answer:

B. 13

Step-by-step explanation:

Solve this by setting up system of equations:

0.25x + 0.10y = 3.95

x + y = 20

x equals the number of quarters and y equals the number of dimes. 0.25 is the value of a quarter and 0.10 is the value of a dime.

1. Multiply one equation to have the same coefficient as the other

0.10 · (x + y = 20) = 0.10x + 0.10y = 2

2. Subtract to find the value of one variable

 0.25x + 0.10y = 3.95

<u>- 0.10x + 0.10y = 2</u>

0.15x = 1.95

3. Solve for x by dividing both sides by 0.15

x = 13

-1\2x+1y=3/4, y-2x=3 , do I divide all the  fractions by 4 to get rid of the fraction  or by 2?
Law Incorporation [45]
You <em>multiply</em> both sides of the first equation by  4.
Then you have . . .
                            -2x + 4y  =  3     and     y - 2x  = 3 .

If you want to get rid of a fraction, you multiply it by itsdenominator.
BUT ... whatever you do to one term on one side of the equation, you
have to do the same to <em>all</em> the terms on that side, AND then you have to
do the same thing to all the termson the OTHER side.
