Step-by-step explanation:

For what value of k does the equation 6(x + 1) + 2 = 3(k5x + 1) + 3 have no solution?

Answers

Answer:

k = (6/15)

Step-by-step explanation:

The equation is:

6*(x + 1) + 2 = 3*(k*5*x + 1) + 3

To have no solutions, we need to have something like:

x + 7 = x + 4

where we can remove x in both sides and end with

7 = 4

So this equation is false, meaning that there is no value of x such that this equation is true, then the equation has no solutions.

First, let's try to simplify our equation:

6*(x + 1) + 2 = 3*(k*5*x + 1) + 3

6*x + 6 + 2 = 3*k*5*x + 3*1 + 3

6*x + 8 = 15*k*x + 6

if 15*k = 6, then the system clerly has no solution.

then:

k = 6/15

then we get:

6*x + 8 = (6/15)*15*x + 6

6*x + 8 = 6*x + 6

8 = 6

The system has no solutions.

Marshall compared his 8 most recent cell phone bills. They were $102, $97 $98 $102 $98 $104 $95 and 102 what was the mode cost

Answers

Answer:

$102

Step-by-step explanation:

The word MODE is a statistical term that refers to the number in a given set of data that occurs the most.

In the above question, we are given the set of data:

$102, $97, $98, $102, $98, $104, $95 and $102

Rearranging, we have:

$95, $97, $98, $98, $102, $102, $102, $104.

The mode cost in the given data set above is the phone cost bill that occurred the most and this is $102.

$102 occurred 3 times in the data set.

5x^2-44x+130=-30+16x

Answers

Answer:

if its answer for x its

Step-by-step explanation:

=4

=8

5x²-44x + 130 = -30 + 16x

5x²-44x + 130 + 30 - 16x = 0

5x² -60x + 160 = 0

devide by 5

x² - 12x + 32 = 0

(x-4) (x-8) = 0

x-4 = 0 then x = 4

x-8 = 0 then x = 8


so x=4 and x=8

I'm trying to understand this!!

Answers

Answer:

eric=12

bill=16

Step-by-step explanation:

you can solve this using two simple algebraic equations. this is the key I will be using:

x=bill

y=Eric

x+y=28

x=y+4

since x is by itself in the second equation, I can replace the x in the first equation with y+4

(y+4)+y=28

subtract 4 from both sides

y+y=24

which is also 2y=24

divide both sides by two.

y=12

so now we know Eric is 12 years old.

using this, we can replace the "y" in the second original equation (x=y+4)

x=12+4

x=16

Bill is 16 years old.

Can someone put this equation in standard form for me?

y-3=1/5(x-3)

Answers

Answer:

-x + 5y = 12

Step-by-step explanation:

Eliminate the fractional coefficient by multiplying both sides by 5:

5y - 15 = x - 3

Combine the constants:  5y = x + 12

Subtract x from both sides:  -x + 5y = 12    This is in standard form
