The equation represents the function f, and the graph represents the function g. f(x)=6x-5A. The rate of change of f is twice the rate of change of g.B. The rate of change of g is twice the rate of change of f.C. The rate of change of f is 3 times the rate of change of g.D. The rate of change of f is the same as the rate of change of g.

What does x equal in this equation: 24+3x=3x+3(7-1) Please help this is due tomorrow!

Answers


                                              24 + 3x = 3x + 3(7 - 1)

Eliminate the parentheses:    24 + 3x = 3x + 3(6)

                                              24 + 3x = 3x + 18

Subtract  3x  from each side:       24  =  18

Look at that for a second.  Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.

That's just another way to say: "The equation has NO solution."


The sum of two numbers is 43. One number is five less than three times the other number. What is the largest number?

Answers

Answer:

31

Step-by-step explanation:

Let the numbers be x and y.

"The sum of two numbers is 43." gives us the first equation.

x + y = 43

"One number is five less than three times the other number." gives us the second equation.

y = 3x - 5

Now we solve the system of two equations below.

x + y = 43

y = 3x - 5

Since the second equation is already solved for y, we will use the substitution method. We substitute 3x - 5 for y in the first equation.

x + y = 43

x + 3x - 5 = 43

4x - 5 = 43

4x = 48

x = 12

The first number is 12. Now we find the second number.

x + y = 43

12 + y = 43

y = 31

The larger number is 31.

Answer:

31 is greater

Step-by-step explanation:

I will solve your system by substitution.

x=3y−5;43=x+y

Step: Solve x=3y−5 for x:

Step: Substitute 3y−5for x in 43=x+y:

43=x+y

43=3y−5+y

43=4y−5 (Simplify both sides of the equation)

43+−4y=4y−5+−4y (Add -4y to both sides)

−4y+43=−5

−4y+43+−43=−5+−43 (Add -43 to both sides)

−4y=−48

(Divide both sides by -4)

y=12

Step: Substitute12foryinx=3y−5:

x=3y−5

x=(3)(12)−5

x=31(Simplify both sides of the equation)

Answer:

x=31 and y=12

31 is greater than 12

Find the sum of the value of 8 in 387,562 and the value of 7 in 7,328,562

Answers

387,562
The 8 is in the ten thousands place, so it equals 80,000.

7,328,562
The 7 is in the millions place, to it equals 7,000,000.

The sum is the value of two numbers added together (the answer to an addition problem).

80,000 + 7,000,000 = 7,080,000

What fraction is greater than 1/2 but less than 3/4

Answers

1/2 = 50%

3/4 = 75%

So something in between that could be 2/3 (which equals 66.67% )

A few others could be: 3/5 ( equals to 60% ) , 7/10 ( equals 70%) 

Hope that helps :)
