What is the slope of the line y+4 = 3(x+6)

Akimi4 [234]

Answer:

Step-by-step explanation:

First you gotta take the equation and bring it to the following form:

$y = ax + b$

The slope of the line is the coefficient of x, a.

In other words:

$y + 4 = 3(x + 6) \\ y + 4 = 3x + 18 \\ y = 3x + 18 - 4 \\ y = 3x + 14$

So, as we can see, the number infront of x is 3. That is to say that the slope of this line is equal to 3.

The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years,

Anika [276]

Answer:

Option 2 is correct.

Step-by-step explanation:

Actual price = $500

After 2 years the worth of item is increased to = $551.25

We need to find the equation that represents y, the value of the item after x years.

According to given information the equation can be of form

$y=500(r)^x$

where r represents the growth and x represents the number of yeras.

We need to find the value of r that represents the growth

The value of y = 551.25, and value of x = 2

Putting values and solving:

$y=500(r)^x\\551.25 = 500(r)^2\\551.25/500 =(r)^2\\1.1025 = (r)^2\\Taking square root on both sides\\\\\sqrt{1.1025}=\sqrt{(r)^2}\\ => (r) = 1.05\\$

Putting value of r in the equation

$y=500(r)^x$

$y=500(1.05)^x$

So Option 2 is correct.

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.
