Find the equation of the line that passes through the points (3,-2) and (-1,6) Explain

Answers

Answer 1
Equation: y = -2x + 4

Explanation: The reason that this would be the answer is because when the 2 points shown are put into graph form (as seen in the picture below) we can see that the slope of the equation is -2 and the y-intercept is 4. So, knowing this, we could fill in our slope-intercept form (y = mx + b) and there we have our equation.

There are 130 people in a sport centre.
61 people use the gym.
68 people use the swimming pool.
60 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
19 people use the gym and the track.
6 people use all three facilities.
A person is selected at random.
What is the probability that this person doesn't use any facility?

Answers

The probability that this person does not make use of the facility is 7/130

How to solve for the probability

61+68+60 - 25-28-19 + 6

= 123

The total number of person in the sport center is given as 130

We have 130 - 123 = 7

This means that there are a total of 7 persons that do not make use of this facility.

Hence the probability of a person not using the facility is 7/130

John has a part time job.
He is paid £6.80 per hour.
This week he worked for 9 1/2 hours.
Work out John's total pay for this week.

Answers

Step-by-step explanation:

Given,

John get paid for working per hour = £6.80

he worked this week = 9 1/2 hr can be written as 19/2 hr.

so, total amount he will get paid for working 19/2 hr

= 19/2 × 6.80

= 19 × 3.40 = 64.60 or 64.6

therefore, John's total.pay of this week is £64.6.

hope this answer helps you dear...take care and may u have a great day ahead!

the Answer is £64.6

Explanation
convert 9 1/2 to a decimal
9.5 which is the hours he worked
then multiply his pay £6.80 by his hours worked 9.5
then you will get the answer £64.6

Answers

Answer:-105

Step-by-step explanation:

Answer:

Ok so, let's break it down

Step-by-step explanation:

-35+(-31)

Let's ignore the parenthesis and the - symbol

35+31

That would equal 66, so now we add back the - symbol which will make it -66

So we already have -66, so now we have -66+(-39)

We do the same thing we did with -35+(-31)

So we have 66+39

That makes -105

So your answer is -105

Answers

Answer: 2.5 feet

Step-by-step explanation:

A 30-60-90 triangle is a special right triangle in which the sides all have a fixed relationship with each other.  We only need to know one side to calculate the other two.

Make the side opposite the 30° angle x, then

The side opposite the 60° angle is x*√3The side opposite the 90° angle is 2x

The side opposite the right angle is 5ft, therefore:

2x = 5

x = 2.5ft, the side opposite the 30° angle

Then x*√3 is the third side:

(2.5)*(1.442) = 3.605 feet

A triangle is shown
What is x?
What is y?
What is z?

Answers

Answer:

x = 44

y = 136

z = 136

Step-by-step explanation:

The angles of a triangle have to add up to 180°

54 + 82 + x = 180

136 + x = 180

x = 44

We know that y and z are vertical angles, so they have the same measurements.

Also, x and the other angle across from it are also vertical angles.

88 + 2n = 360

2n = 272

n = 136

Therefore,

x = 44

y = 136

z = 136

Deion is making sandwiches for a picnic. He uses 2 slices of cheese to make each sandwich,
and he has a package of cheese with 24 slices. How many sandwiches can Deion make before
he runs out of cheese?
answer quickly please!

Answers

Answer:

12 sandwiches

Step-by-step explanation:

We know that Deion has 24 cheese slices, and uses 2 slices per sandwich, so in order to find how many sandwiches he can make, we can divide the total number of cheese slices by the number used to make a sandwich:

24 / 2 = 12

Therefore, Deion can make 12 sandwiches before he runs out of cheese.

Answers

Step-by-step explanation:

anything whole or complete is designated as 100%.

what is x% of that whole ?

well, we need to multiply the whole with the same factor we need to multiply 100 with to get x.

100×f = x

f = x/100

whole × f = x% of the whole

so, when we are looking for 5%, what did that mean ?

it means that x = 5, and f = 5/100.

therefore, 5% of $13 is

13 × 5/100 = 65/100 = 0.65

so,

basic cost = $13

tax rate = 5%

tax amount = $0.65

and

basic cost = $13

tax amount = $0.65

total cost = 13 + 0.65 = $13.65

as 5/100 = 0.05

we have seen that the tax amount is simply $13×0.05

and when we add the tax amount to the basic cost, we need to add $13×1 (basic cost) to the $13×0.05 (tax amount), and we get as total

total cost = $13×(1+0.05) = $13×1.05 = $13.65

so, the decimal factor we can use directly without going through all the detail above is : 1.05

What is the equation, in slope-intercept form, of the line that passes through
the point (7, 2) and is parallel to y= -2x+1?

Answers

Answer: y  = - 2 x  + 16Step-by-step explanation:

Find the slope of the parallel line

(7, 2) and is parallel to y= -2x+1?

When two lines are parallel, they have the same slope.  

                ⇒  if the slope of the given line is = - 2      

                     then the slope of the parallel line (m) = - 2

Determine the equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  

                              ⇒  y - 2  =  - 2 (x - 7)                                  

                           

We can therefore write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:  

                     since   y - 2  = - 2 (x - 7)  

                           ∴   y  = - 2 x  + 16

Answer: 8.3

Explanation:

The mean is the average of a data set; it is the number that falls directly in the middle of the data set.

The formula to find the average is: a=sum of terms/ number of terms.

Therefore, we just add up all the values in the data set and divide by how many numbers there are.

3+9+10+10+4+10+10+10/8 = 8.25. We added up all the numbers and then divided by how many numbers there were, which was 8.

8.25 rounded to the nearest tenth is 8.3.

Can you please help me with my homework I don’t get it.

Answers

The slope-intercept form is y = mx + b where:

m= slope
b = y-intercept (The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.)

To start with, you’ll need two ordered pairs (x,y) from the line to solve for slope.

For the first graph:
Let (x1,y1) = (0,2)
(x2,y2) = (2,4)

Substitute these values into the slope formula:

m = (y2 - y1)/(x2 - x1)

m = (4 - 2)/(2 - 0)
m = 2/2 = 1

Therefore, the slope (m) = 1.

Next, for the y-intercept, the point where it crosses the y-axis is at point (0, 2). Therefore, the y-intercept (b) = 2.


Thus, the linear equation of the first graph in slope-intercept form is: y = x + 2.


For the 2nd graph, do the same steps as we have done in the 1st graph:

Choose 2 ordered pairs:

Let (x1,y1) = (0,2) — right off the bat, this is the y-intercept.
(x2,y2) = (2,0)

Substitute these values into the slope formula:

m = (y2 - y1)/(x2 - x1)

m = (0 - 2)/(2 - 0)
m = -2/2 = -1

Therefore, the slope (m) = 1.

For the y-intercept, I noted earlier that (0,2) is the y-intercept. Hence, b = 2.

The linear equation in slope-intercept form of the 2nd graph is: y = -x + 2
