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.

Answer:

y = -1x

Step-by-step explanation:

The slope-intercept equation is written y = mx + b. "y" stays the same. "m" is the slope. "x" stays the same. "b" is the y-intercept.

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.

Answer:

15x20

Step-by-step explanation:

If you look closely in the question, it says one inch is 10 feet in the actual room. So what you would do is take the measurements and multiple by 10. All sides of the room are 3 inches but what the trick is, it asks you for the dimensions of the kitchen. So you would multiple 2x10 and 1.5 x 10 :)!

Answer:

$8.4375 per game

Step-by-step explanation:

From. The picture attached :

Season long Ticket cost for the bleachers sitting area is : $810

Given that the number of home games in a season is 96

The cost per unit of game could be calculated as :

Cost of season long Ticket / number of home games

= $810 / 96

= $8.4375

$8.4375 per game

Answer:

Factor 8 out of 32w - 56xy

8 ( 4w - 7xy )

GCF of 32 and 56 is 8.

So we have 4(8w)-7(8xy)

Answer:

these are tough,   it takes a lot of practice to get used to these, sooo

Step-by-step explanation:

we know the slope, m= -5/3,   and we're given a point so use the point slope formula

y= mx + b

the point we are given is in this form  (x,y)

then plug the information into our point slope formula

y = (-5/3) x  + (-2)

y = -5x/3 -2

Answer:

im sorry i cant read that

Step-by-step explanation:

its to far away :(

the formula is y=mx+b

mx is the slope and b is the y-intercept

y=-2/7+5

(sorry if its wring its 12am im tired-

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.

Answer:

Answer:

[tex]\boxed {\boxed {\sf SA= 753.6 \ in^2}}[/tex]

Step-by-step explanation:

The surface area of a cylinder is found using this formula.

[tex]SA=2 \pi rh+ 2 \pi r^2[/tex]

We know the diameter is 20 inches and the height is 2 inches. We must find the radius.

Now we know that:

[tex]r= 10 \ in \\h= 2 \ in[/tex]

Substitute the values into the formula. Also, plug 3.14 in for pi.

[tex]SA=2 (3.14)(10 \ in)(2 \ in)+ 2 (3.14)(10 \ in)^2[/tex]

Solve according to PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction.

Solve the exponent.

[tex]SA=2 (3.14)(10 \ in)(2 \ in)+ 2 (3.14)(100 \ in^2)[/tex]

Multiply all the numbers together.

[tex]SA=2 (3.14)(20 \ in^2)+ 2 (3.14)(100 \ in^2)[/tex]

[tex]SA=125.6 \ in^2+628 \ in^2[/tex]

Add.

[tex]SA= 753.6 \ in^2[/tex]

The surface of the cylinder is 753.6 square inches.
