All of the following are equivalent, except _____.

marusya05 [52]

1. Given (12+3)x, we can sum the numbers in the parenthesis to get 15x

2. Given 12x+3x, we can factor x to get (12+3)x and get the same as 1.

3. Given (12+3x)x, we have to distribute the x and we have $12x+3x^2$

4. This expression is already simplified.

Daniel wanted to know his approximate score on the final exam for his mathematics class. His professor hinted that his score was

hammer [34]

Answer: The raw score for Daniel's exam grade is 101.69.

Step-by-step explanation:

For x be any random variable.

Formula for z-score :

$z=\dfrac{x-\mu}{\sigma}$ , where $\mu$ = population mean

$\sigma$ = population standard deviation.

Let x be the raw score for Daniel's exam grade.

As per given , we have

$\mu=90$ , $\sigma=7$ and z= 1.67 , put these values in the above formula , we get

$1.67=\dfrac{x-90}{7}\\\\\Rightarrow\ x-90=7(1.67)=11.69\\\\\Righarrow\ x=11.69+90=101.69$

Hence, the raw score for Daniel's exam grade is 101.69.

Solve s=m/4(a+h) for h

Pavlova-9 [17]

Answer:

h = (m/4 - as)/s

Step-by-step explanation:

s = m / 4(a+h)

(a+h) · s = m/4 >multiplied (a+h) on both side

as + hs = m/4 >distributed the s to (a+h)

hs = m/4 - as >subtracted as on both side

h = (m/4 - as)/s >divided s on both side

Find an equation of the line through (3,8) and parallel to y = 4x - 3.

aksik [14]

Answer: y=4x-4

Step-by-step explanation:

To find the equation fo the line parallel to the given line, we can use the given point to find the y-intercept. We know that the slope must stay the same because parallel lines NEVER touch or cross. This means that the slope MUST be the same.

y=4x+b

We can use the given point to find the y-intercept.

8=4(3)+b [multiply]

8=12+b [subtract both sides by 12]

b=-4

Now that we have found the y-intercept, we can complete the equation.

y=4x-4

Which of the following describes the translation of the graph of y = x 2 to

VLD [36.1K]

Answer:

reflect over the x-axis and shift down 3

Step-by-step explanation:

The leading coefficient of -1 means the graph is reflected over the x-axis. The addition of -3 to the function means each graphed point is shifted down 3 units from the original.

The graph of y = -x^2 -3 is the result of the transformation ...
