The rest of the statement is (3x+1) = 3x²+22x+7.

The divisor is one factor, and the quotient is the second factor.  The factors get multiplied to make the dividend.

Answer:

Complete sentence is (x+7)<u>(3x+1)</u>=<em>3x²+22x+7</em>

Step-by-step explanation:

If (3x^2+22x+7)\div(x+7)=3x+1

We need to write into another form

if \dfrac{p(x)}{q(x)}=r(x) then p(x)=r(x)\times q(x)

\dfrac{3x^2+22x+7}{x+7}=3x+1

p(x)=3x^2+22x+7

q(x)=x+7

r(x)=3x+1

We can write as

(x+7)\times \underline{(3x+1)}=\underline{3x^2+22x+7}

Thus, Complete sentence is (x+7)<u>(3x+1)</u>=<em>3x²+22x+7</em>

In a statistics course, a linear regression equation was computed to predict the final exam score from the score on the first te
eduard

Answer:

2.5

Step-by-step explanation:

The predicted regression equation is

y^=10+0.9x

where y= final exam score and x=first test score.

Also, we are given that Carla's final exam score y is 98 and Carla's first test score x is 95. We have to find residual for Carla.

Residual=Observed -predicted=y-y^

y^=10+0.9x

We know that Carla's first test score=x=95.

So,

y^=10+0.9(95)

y^=10+85.5

y^=95.5

Residual for Carla=y-y^=?

We know that Carla's final exam score=y=98.

So,

Residual for Carla=98-95.5=2.5

The sum of two numbers is 61 and the difference is 3 what are the numbers
madam [21]

Answer:

<h3>29 and 32</h3>

Step-by-step explanation:

Let x = number

Let y = second number

We know that there are two true equations from this. Here is shown below the equations.

x + y = 61

x + 3  = y

We could use the substitution method for finding the numbers. After that, we continue on to solve to find the first number.

x + (x+3) = 61

2x + 3 = 61

2x = 58

2x/2 = 58/2

x = 29

Now that we know that the first number is 29, plug it in to the second equation to find the second number.

x + 3 = y

29 + 3 = y

y = 32

Proof that these numbers are the correct answer:

32 + 29 = 61

61 = 61 (Which is true!)

To support me, please give me the brainliest answer. It would be greatly appreciated. Thank you!
