Line perpendicular to y = -2x - 7 when it passes the points (-2,-3)

Answers

Answer 1

Answer:

The line is  y = 1/2x - 2

Step-by-step explanation:

The required  line will have a slope of -1/-2 = 1/2.

Using the point slope form of a line:

y - (-3) = 1/2(x -  (-2))

y + 3 = 1/2x + 1

y = 1/2x - 2.

Answer:

Volume = 0.1 cu. cm.

Step-by-step explanation:

p = m V

where p = 10.5 grams/cu. cm.

          m = 105 grams

plugin values into the equation:

10.5 grams/cu. cm. = 105 grams V

V = 10.5 grams/cu. cm.

         105 grams

V = 0.1 cu. cm.

(Show steps )

Answers

Answer:

Rewriting the equation in slope intercept form is: Y= -8x+4

Step-by-step explanation:

Im sure there's a faster way to solving this, but I'm just in 8th grade so I'm gonna apply what I know so far.

First of all, we know that our slope is -8... so we have y= -8x so far

From here, to find out y intercept I knew that our slope deals with all the points assigned, therefore we know that from -4 the change would be -8 so we get -12. We can also go the other way. This means that we plus 8 to get positive 4. (Side note: the change in our x value is 1 so we know that our y intercept is always dealing with a 0 in the x position) ex. (0,9) the y intercept would be 9.

To wrap things up, the slope is -8 and the y intercept is 4.

We then get Y= -8x+4

Hope this helps! :)

Pls help thank you

Answers

Answer:

           These numbers are 3 and 9

Step-by-step explanation:

x - smaller number

3x - three times the smaller number = the larger number

2×3x - twice the targer number

2×3x+3x  - twice the larger is added to three times the smaller

2×3x + 3x = 27

6x + 3x = 27

3 x 4x = 12x

3 x -7 = -21

12x -21 = 27

12x -21 + 21 = 27 + 21

A taxi service charges you $1.50 plus $0.60 per minute for a trip to the airport. The distance to the airport is 10 miles, and the total charge is $13.50
How many minutes did the ride to the airport take?

Answers

The taxi ride should be twenty minutes long

Answer:

20 minutes

Step-by-step explanation:

The question can be shown like so, 1.5+0.6x

Since the total charge was 13.5, you can write an equation

13.5=1.5+0.6x

Simplify using property of subtraction

13.5 - 1.5= 1.5 - 1.5 + 0.6x

12 = 0.6x

Simplify using property of division

12/0.6= 0.6x/0.6

The poetry club had its first bake sale and they made 79.35 dollars. The club members are planning to have 4 more bake sales. Leslie said if we make the same amount at each bake sale we will earn 3,976.50 dollars. Peggy said no way we will earn 396.75 after bake sales. Use estimation to help Peggy explain why Leslie reasoning is incorrect.

Answers

Answer:

Peggy is correct, their total bakes sale = $396.75

Step-by-step explanation:

Using estimation to help Peggy explain why Leslie reasoning is incorrect.

From the question we can see that:

First bake sale they made = $79.35

4 more bake sales making the same amount = 4 × $79.35

The total amount they would make from the bake sales =

$79.35 + (4 × $79.35)

= $396.75

Peggy was right. Leslie's reasoning was incorrect.

[tex]\large\underline{\underline{\red{\rm\blue{\longmapsto} Step-by-step\: Explanation:-}}}[/tex]

Here , the given data is :

Principal = Rs 4400 . ( P )Time = 3 years . ( T ) Rate of Internet = 8% . ( R )

We can calculate Simple Interest using ,

[tex]\boxed{\purple{\bf Simple\: Interest=\dfrac{P\times\:R\:\times\:T}{100}}}[/tex]

On substituting the respective values ,

⇒ SI = P × R × T / 100.

⇒ SI = Rs 4400 × 8 × 3 / 100 .

⇒ SI = Rs 44 × 8 × 3 .

SI = Rs 1,056 .

Hence the required Interest is Rs 1,056.

Answer:

92

Step-by-step explanation:

Start with the first sentence. 7 crates of 12 eggs each and you need to find out how many eggs that is; that's just 12 + 12 + 12 + 12 + 12 + 12 + 12, or 12 * 7, which equals 84.

Real question is: how many do they have now? Well, if they had 8 eggs at first and they just bought 84 more, then the answer is just 8 plus the 84 that they just bought, which is 92.

Please mark as Brainliest! :)

Answer:

Your correct answer is that they now have 76 eggs left.

Step-by-step :

So, to start off, they had 7 boxes with each box with 12 eggs. So multiply 7 by 12.

7 x 12 = 84

Now, they ate 8 eggs.

84 - 8 = 76 eggs

A lawsuit between Uber and Waymo, Googles self-driving car project, settled in February 2018 illustrates the fierce battle to develop driverless car technology. Many cars already employ semi-autonomous technology, such as parking assistance and lane monitoring. The National Highway Traffic Safety Administration (NHTSA) suggests that automated vehicles could promote safety on the road. According to NHTSAs Federal Automated Vehicles Policy, 94 percent of car accidents are linked to human choice or error. Automated vehicles, the NHTSA writes, could reduce the frequency of crashes by eliminating some human error on the roads. The policy indicates positive features of automated vehicles beyond safety, including potential environmental benefits and increased mobility for those otherwise unable to drive. The cutting-edge technology, however, presents ethical questions and other concerns.
