Answer:

y = 5x - 5/2xy + 79

Step-by-step explanation:

First we need to solve for m which is slope.

Subtract 5y from both sides

2x = 10 - 5y

Then divide each term by 2

2x/2 = 10/2 + -5y/2

Then simplify to the left

x = 10/2 + -5y/2

Then simplify the right side

x = 5 - 5y/2

Next we have to find the value of b using the formula y = mx + b

So

y = (5 - 5y/2) * x + b

y = (5 - 5y/2) * (4) + b

9 = (5 - 5(9)/2) * (4) + b

Rewrite

(5 - 5(9)/2) * 4 + b = 9

Simplify more

Multiply 5 by 9

(5 - 45/2) * 4 + b = 9

Multiply by 2/2 to write 5 as a fraction

5 * 2/2 - 45/2) * 4 + b = 9

Then combine 5 and 2/2

(5 * 2/2 - 45/2) * 4 + b = 9

Combine the numerator over the denom

5 * 2 - 45/2 * 4 + b = 9

Simplify the numerator

-35/2 * 4 + b = 9

Cancel the common factor of 2

-35 * 2 + b = 9

Multiply

-70 + b = 9

Move the terms without b to the right side

b = 9 + 70 > b = 79

Now we substitute all the values into y =  mx + b

y = 5x - 5/2xy + 79

Answer:

-1/2

Step-by-step explanation:

When the equation of a line is given in the form y = mx + b like this is, the slope is simply the m value!

Step-by-step explanation:

x < 6

This is because there is an open hole at 6, meaning we exclude it from the solution set. Stuff to the left of 6 (ie smaller than 6) is shaded, which is why we go for x < 6

The inequality represented in the given graph is x < 6.

Given is a number line where an inequality is marked.

We have to find the inequality which represents in the number line given.

Here, a graph or a number line where the numbers are marked from 1 to 9 is drawn.

A blue line is drawn prior to the number 6. So the inequality sign is "<".

An open circle is over the number 6. So 6 is not included in the inequality.

So, the required inequality is x < 6.

The correct option is C. x < 6.

Answer:

$99.11 dollars

Step-by-step explanation:

Given the following question:
$110 dollars for a chair...
15% off from a coupon...
Then a 6% sales tax....

[tex]\frac{15\times110}{100} =15\times110=1650\div100=16.5[/tex]
[tex]110-16.5=93.50[/tex]
The chair costs $93.50 dollars after the 15% off coupon.

Now the 6% sales tax:

[tex]\frac{93.5\times6}{100} =93.5\times6=561\div100=5.61[/tex]
[tex]93.5+5.61=99.11[/tex]
[tex]=99.11[/tex]

After the 15% coupon and the 6% sales tax, the chair will cost "$99.11 dollars."

Hope this helps.

Answer:

$579.60

Step-by-step explanation:

First, we need to find the area of the (floor) of the room.

Area = Length * Width

We can plug in the given values into the equation.

Area = 14 yd * 18 yd

Area = 252 yd²

We can set up a conversion factor to see how much it costs to carpet the room...

[tex]\frac{\$2.30}{1 \ yard^2}*252 \ yards^2[/tex]

Cancel out the yd²...

$2.30*252=$579.60

Answer:

m = -1; b = 2

Step-by-step explanation:

the first step in solving this equation is to find the slope

so we use the equation (y2-y1)/(x2-x1)

so with this the equation is

(4 - 3)/(-2 + 1)

then it would be 1/-1

that is -1

so the function so far is f(x) = -x + b

to find the b you would plug in the coordinates

we can plug in the first set

3 = 1 + b

b = 2

so the m is -1 and the b is 2

Answer:

dasd

Step-by-step explanation:

Given:

2(x + 5)-7= 3(x - 2)

To Find:

• Value of x

Solution:

⇒ 2(x + 5)-7= 3(x - 2)

⇒ 2x+10-7= 3x - 6

Rearranging the like terms,

⇒ 3x-2x = 10 + 6-7

⇒x=16-7

⇒x=9

Verification:

⇒ 2(x + 5)-7= 3(x - 2)

Putting x = 9,

⇒2(9+5)-7= 3(9 - 2)

2(14)-7= 3(7)

⇒28-7=21

⇒ 21 = 21

→ LHS = RHS

Answer:

  x = 19

Step-by-step explanation:

When a triangle is cut by a line parallel to its base, the resulting two triangles are similar. That means corresponding sides are proportional (their ratios are equal).

There are several ways the ratios can be written, but I like to choose one that has the variable in the numerator. Here's the proportion and its solution.

  [tex]\dfrac{x+5}{16}=\dfrac{30}{20}\\\\x+5=24\qquad\text{multiply both sides by 16}\\\\x=19\qquad\text{subtract 5 from both sides}[/tex]

Additional comment

Technically, the corresponding sides of the triangles would be ...

Since the parts labeled (x+5) and 16 are each the same fraction of their entire side, those parts are corresponding also, and will have the same proportion as other corresponding sides.

Answer:

22/10 or 11/5

Step-by-step explanation:

There are two (2) whole and two tenths (2/10).

You have to multiply the 2 whole by the denominator and add it to the numerator.

Step by step:

1) 2 and 2/10

2) (2*10) = 20

3) add 20 to 2, then put it on the /10

4) 22/10, then reduce the fraction

5) 11/5

Final answer: 11/5

Answer:

The first option is correct.

Moving 1.5 units to the left (or -1.5 units to the right).

Moving 1 unit down (or -1 unit up).

Therefore you get the result of (-1.5, 1) as is the location of the rink.
