4) Line L has equation y = 4x - 7, and line M is parallel to line L and passes through the point (2,15). Determine the equation of line M. A) y = 4x + 7 B) y = 2x + 7 ©). y = 4x + 15 D) y = 2x + 15​

Answers

Answer:

the answer is A.y=4x+7

Step-by-step explanation:

Line M is parallel to the line L, so the equation for line M isy=4x+b

Plug in the coordinates of the point (2,15) , you get:

15=4*2+b

Solve that to get b=7

Therefore the equation of line M is y=4x+7

You estimate that there will be 85 people at your party, but only 75 show up, what is the percent error of your estimate?

Answers

Answer:

Percentage error of your estimate = 13%    

Step-by-step explanation:

Given

Approximate value = 85

Exact value = 75

To determine

Percentage error can be determined using the formula

Percentage Error =  |Approximate Value − Exact Value| / |Exact Value| × 100%

                             = |85 − 75| / |75| × 100%

                             = 10 / 75 × 100%

                             = 0.1333 × 100%

                             = 13%

Therefore, percentage error of your estimate = 13%

A collector has 2792 coins
altogether. Half of the coins
are on display. The collector
buys more coins at an auction
so that the coins on display
are now 40% of the collection.
How many coins are bought at
the auction?

Answers

Answer:

3490 coins

Step-by-step explanation:

Given data

Total coins= 2792 coins

Half of the coins are on display

that is 50% are on display

=2792/2

=1396

let the coins bought be x

40% of x= 1396

40/100*x= 1396

0.4x= 1396

x=  1396/0.4

x=3490

Hence 3490 coins were bought

Please find the slope of (-2, 4) and (3, -5)

Answers

Answer:

The slope of the line = m = -9/5

Step-by-step explanation:

Given the points

(-2, 4)(3, -5)  

Determining the slope between (-2, 4) and (3, -5)

(x₁, y₁) = (-2, 4)

(x₂, y₂) = (3, -5)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]  

                 =  [-5 - 4] / [3 - (-2)]

                 = [-9] / [3 + 2]

                 = -9/5

Thus, the slope of the line = m = -9/5  

Answer:

m = -9/5

Step-by-step explanation:

Taking (-2,4) as (x1,y1), and

Taking (3,-5) as (x2,y2)

Using the slope (m) formula:

[tex]m = \frac{y2-y1}{x2-x1}[/tex]

= (-5-4)/(3-(-2))

= -9/(3+2)

= -9/5

Hence, the slope is -9/5
