Answer:

Step-by-step explanation:

4y - 2(5 - y + 4) = 4y - 2(9 - y)

                         = 4y + 9*(-2) - y *(-2)

                         = 4y  - 18 + 2y      {Combine like terms 4y and 2y}

                         = 6y - 18

6y - 18 = 6*y - 6*3

           = 6(y - 3)

6y- 18 =  2 *3y - 2*9

          = 2(3y -9)

2(3y - 9) and 6(y- 3 ) are equivalent to 4y - 2(5- y +4)

Others are not equivalent

What is the mass of an object if it takes a net force of 32 N to accelerate
Sonbull [250]

We will find the answer using the second law of motion i.e. Force is equal to the product of mass and acceleration.

\sf \: F=ma

Where,

  • F is force
  • M is mass
  • A is acceleration

In our case,

  • F = 32 N
  • A = 0.88m/s
  • M = ?

Let's solve for M ~

\tt \: 32 = m \times 0.88

\tt \: 32 = 0.88m

\tt \: 0.88m = 32

\tt \: m = 36.36

<em>Thus, The mass of object is 36.36 </em><em>grams</em><em>.</em><em>.</em><em>.</em><em>~</em>

A social psychologist conducts an experiment and finds a statistically significant result. This means that the a. experiment is
coldgirl [10]

Considering that the hypothesis test found an statistically significant result, it is found that the correct option is:

c. probability of obtaining this finding by chance alone is less than some quantity.

<h3>What is an hypothesis test?</h3>
  • When a hypothesis test, there are two hypothesis, the null and the alternative hypothesis.
  • There is also a significance level.
  • If the probability of obtaining the finding by chance is less than the significant value, the result is statistically significant.

Hence, according to these bullet points, option C is correct.

Ted has $3.90. He has only dimes and quarters. He has 27 coins altogether. How many of each does he have
mestny [16]

Answer: 8 quarters 19 dimes

Step-by-step explanation:

we already know 8+19=27, if 4 quarters equals a dollar then you use 4 quarters each to create 2 dollars.

then, use 10 dimes to create another dollar summing it up to $3. now all we have to do is make 90 cents, and we've already used 18 coins.

if we used another 9 dimes, that would equal 90 cents.

in conclusion, 4+4= 8

8+10= 18

18+9= 27, and having $3.90

For the function f(x)=-3x+2, find f(2)=
dsp73

Answer: f(2) = -4

Step-by-step explanation: Here we're given the function f(x) = -3x + 2 and we are asked to find f(2).

In other words, if we put an <em>x</em> into our function, we get a -3x + 2 out so what happens when we put a 2 into the function?

Well if we put a 2 into the function,

that's f(2) and we get -3(2) + 2 out.

Now all we have to do is simplify on the right side.

-3(2) is -6 so we have -6 + 2 which is -4.

So f(2) is -4.
