First, we need to find how much Beatrice earns each month, so you need to find the difference between the two- and four-month amount and divide by 2, which gives you 150. So, we know she gets 150 dollars each month. Multiply that by two to get 300, and subtract that from 850 to see how much she was awarded in the beginning, which was 550. So, the answer is G.

Ray and Claudia are writing in journals. Ray has written 16 pages and he now writes 2 pages every day. Claudia has written only 2 pages, but she now writes 4 pages every day. In how many days will they have written the same number of pages?

Answers

Answer:

6 days

Step-by-step explanation:

Step one:

Given data

For Ray

He has 16 pages already

Now he is writing 2 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=2x+16-------------1

For Claudia

He has 2 pages already

Now he is writing 4 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=4x+2-------------2

Step two:

let us equate equation 1 and 2 to find x

2x+16=4x+2

collect like terms

2x-4x=2-16

-2x=-12

divide both sides by -2

x=12/2

x=6

Therefore it will take 6 days for them to have the same number of pages

Step-by-step explanation:

f(x) = 2x, find the ordered pair when x = 1. O (1,2) 0 (4,1) (2,1) O (1,4)​

Answers

Answer:

The ordered pair is (1, 2) ⇒ A

Step-by-step explanation:

In the function f(x) = y

x is the domain of the functiony is the range of the functionThe domain is all the x-coordinates of the points lie on the graph of the functionThe range is all the y-coordinates of the points lie on the graph of the function

That means any ordered pair (x, y) satisfy the function f(x) = y, lies on the graph of the function

∵ f(x) = 2x

→ That means y = 2x

x = 1

→ Substitute the value of x in the function above

∴ f(1) = 2(1)

f(1) = 2

→ That means at x = 1, y = 2

The ordered pair is (1, 2)

(-12,14) and (6,-1) write the linear equation in slope-intercept form that passes through the given points. PLEASE HELP ASAP THANK YOU!!!

Answers

The equation of the line written in slope intercept form is 0.8333x + 24

From the question given :

x1 = - 12 ; y1 = 14 ; x2 = 6 ; y2 = - 1

General form of a slope intercept equation :

y = bx + c

b = slope = (y2 - y1) / (x2 - x1)

Slope = (-1 - 14) / (6 - (-12)) = - 15 / 18 = 0.8333

The intercept, c can be obtained thus :

14 = 0.8333(-12) + c

14 = - 10 + c

14 + 10 = c

c = 24

Therefore, the equation can expressed thus y = 0.8333x + 24

Answers

Answer: (-6,-9)

Step-by-step explanation: you probably don't wanna read this but in case someone asks you about it- first start by putting the first equation into graphing form, turning it into 2y=-3x+12.

then you can go ahead and multiply the second equation by two to get 2(y=1/2x-6), which is 2y=x-12.

next, just subtraction! 2y=-3x+12 minus 2y=x-12!

You get -4x=24, which leaves you to divide both sides by -4 to get x=-6!

now to put in x for the solution, you take a equation(either one) and put in x

[y=1/2(-6)-6]

[y=-3-6]

[y=-9]

so your points are (-6,-9)

Point R on the coordinate grid below shows the location of a car in a parking lot. A second car needs to park 6 units above R to leave room for a utility truck. What are the coordinates of the location of the second

Answers

Answer:

[tex]R' = (-4 , 4)[/tex]

Step-by-step explanation:

Given

See attachment for the grid coordinate

From the attachment, we have that:

[tex]R = (-4,-2)[/tex]

Required

Determine the coordinates of the second truck

Represent the position with R'

From the question, we understand the position of R' is 6 above R

When a point (a,b) is moved n point above, the new point becomes (a, b + n)

So:

[tex]R = (-4,-2)[/tex]

When moved 6 points above becomes:

[tex]R' = (-4 , -2 + 6)[/tex]

[tex]R' = (-4 , 4)[/tex]

Hence, (-4,4) answers the question
