(-1,0), slope of -2 whats the answer?

Mathematics

Answer:

y = -2x - 2

Step-by-step explanation:

since the y-intercept is the line of intersection on the y axis, and the slope is -2, you would have to go down 2 and to the right 1 to get a y-intercept at -2

meaning the equation would be

y = -2x - 2

how do you write these equations in slope-intercept form y+1=2x-3 ,2x-3=y+1 , 2y+2=4x-6. Are they the same or different?
inna [77]

y+1=2x-3

y=2x-4

2x-3=y+1

2x-4=y

y=2x-4

2y+2=4x-6

2y=4x-8

y=2x-4

They are all the same: y=2x-4

So first you would divide 1950/6 to find the amount for one year of their age.
Then you would multiply that by the ages, which should get you 4 numbers, then you all those numbers together. Try 9750.

Select the correct answer.<br> Simplify the expression
KonstantinChe [14]

Answer: A

Step-by-step explanation:

Since multiplication is the only operation under the radical, you can apply the root to each term. Im not sure if I worded that correctly, but ill hopefully explain correctly.

First we need to take the cubed root of 648. This number doesn't have a perfect root, but it can be simplified. 648 is the same as 216*3, and 216 has a perfect cubed root of 6. So we can bring the 6 outside of the radical

3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}

The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.

18x\sqrt[3]{3x^3xy^3y^3y^2}

The cubed root and the cubed power will cancel and can be brought outside the radical18x*xy^2\sqrt[3]{2xy^2} =18x^2y^2\sqrt[3]{3xy^2}

(CO 3) A survey indicates that shoppers spend an average of 22 minutes with a standard deviation of 8 minutes in your store and
padilas [110]

Answer: 0.60

Step-by-step explanation:

Given: Mean : \mu = 22\text{ minutes}

Standard deviation : \sigma = 8\text{ minutes}

The formula to calculate z is given by :-

z=\dfrac{x-\mu}{\sigma}

For x= 20 minutes

z=\dfrac{22-20}{8}=0.25

The P Value =P(z

Hence, the probability that a randomly selected shopper will spend less than 20 minutes in the store= 0.60
