Which of the following ordered pairs represents a solution to the linear equation y=6x-2x

The ordered pairs are not given, but they are going to be a solution if they are in the following format:

.

The equation given is:

We can simplify it:

Thus, ordered pairs (x,y) are a solution if they are in the following format:

.

A similar problem, which asks if an ordered pair is a solution of an equation, is given at brainly.com/question/10585472

Since you didn't list the points, I can only give you some example points. Then, you can select the points in your problem.

First, the equation can be simplified to just: y = 4x

Now, just select points for x, then multiply by 4 to get y.

COLLEGE

In four years Cranston’s age will be the same as Terrill’s age is now. In two years time, Terrill will be twice as old as Cranston. Find their ages now.

Uuuuh...

c + 4 = t

t + 2 = 2c

c + 4 = 2c – 2

c = 2

t = 6

or

c = t - 4....................................(1)

in 2 years we have:

t + 2 = 2(c + 2)

i.........e......... t + 2 = 2c + 4

=&gt; t - 2c = 2...........................(2)

(1) into (2) for c gives:

t - 2(t - 4) = 2

i.........e......... 8 - t = 2

so, t = 6 and c = 2

therefore, terrill is 6 and cranston is 2

and, in 2 years time they shall be 8 and 4....................................i..... terrill being twice cranston's age

i lost myself the first time i solved it

c + 4 = t

t + 2 = 2c

c + 4 = 2c – 2

c = 2

t = 6

or

c = t - 4....................................(1)

in 2 years we have:

t + 2 = 2(c + 2)

i.........e......... t + 2 = 2c + 4

=&gt; t - 2c = 2...........................(2)

(1) into (2) for c gives:

t - 2(t - 4) = 2

i.........e......... 8 - t = 2

so, t = 6 and c = 2

therefore, terrill is 6 and cranston is 2

Answer:

Cranston's Age: 2 years

Terril's Age: 6 years

Step-by-step explanation:

c = Cranston

t = Terril

Information we have:

c + 4 = t

t + 2 = 2c

So, if Cranston is 2 and Terril is 6, it's true as c + 4 (2 + 4) is 6 and When Cranston and Terril age 2 years, Cranston will be 4 and Terril will be 8, so Terril will be twice of Cranston's age.

*A lot of people forget the part where Cranston will ALSO age, so they get t = 10 and c = 6

Find the max and min values of f(x,y,z)=x+y-z on the sphere x^2+y^2+z^2=81

Using Lagrange multipliers, we have the Lagrangian

with partial derivatives (set equal to 0)

Substituting the first three equations into the fourth allows us to solve for :

For each possible value of , we get two corresponding critical points at .

At these points, respectively, we get a maximum value of and a minimum value of .

Which equation represents a line that is perpendicular to the line y= 1/4x - 1 A) Y=-1/4x - 3

B) Y= 1/4X + 1

C) Y= 4X-5

D) Y= -4X - 2

Y = 1/4x - 1....the slope here is 1/4....but for a perpendicular line we need a negative reciprocal slope...all that means is " flip " the slope and change the sign. 1/4....flip it....4/1.....change the sign....-4/1 or just -4. So our perpendicular line will have a slope of -4. The only one in ur answer choices with a slope of -4 is D.....so ur answer has to be D.
