how do you simplify this
8-6/3
6*8/3

=======================================================

Explanation:

The -2 outside the first matrix multiplies to every item inside that first matrix.

So the x updates to -2x in the upper left corner.

That -2x adds to the 3 in the upper left corner of the second matrix. The sum -2x+3 must be equal to the value in the upper left corner of the third matrix.

Everything is focused on the upper left corner.

So we must solve -2x+3 = x

Doing so leads to...

-2x+3 = x

3 = x+2x

3 = 3x

3x = 3

x = 3/3

x = 1

Answer:

$200

Step-by-step explanation:

Here is the full question

You can upgrade lighting at your factory to LED bulbs that cost $6.95 each and last an average of 5 years. It costs $3 in labor to change a bulb. Over a 10-year period, about how much will it cost per year to install LED bulbs in 100 lamps and change the bulbs when they burn out?

in 10 years, the bulbs would be changed twice

Total cost incurred per bulb in 10 years = (6.95 +  $3) x 2 = $19.90

Since there are 100 bulbs, total cost incurred would be - $19.90 x 100 = $1990

Cost per year = $1990 /  (6.95 +  $3) = $200

Answer:

yes

Step-by-step explanation:

your m is your slope,your b is the y-intercept, and your y is what you are solving for.

Answer:

Y=mx+b is an equation for a linear equation

M is the slope of the line and B is the y-intercept

The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Every straight line can be represented by an equation: y = mx + b.

Answer:

B) 2w + 3c = 9.45 AND 4w + 5c = 14.75

Step-by-step explanation:

Let us represent:

Number of water bottles = w

Number of bag of chips = c

Hence:

Samaia buys two water bottles and three bags of chips for $9.45.

2w + 3c = 9.45......Equation 1

Abdullah goes to the same store and buys four water bottles, as Samaia, and five bags of chips, same as ones Samaia bought, for $14.75.

4w + 5c = 14.75......Equation 2

Which choice below accurately represents a system of equations, w for water bottles and c for chips, for this scenario?

Option B) 2w + 3c = 9.45 AND 4w + 5c = 14.75 is the correct option.

Since each value of the input is mapped to only one value of the output, we have that graph w represents a function.

When it has no vertically aligned points, that is, each value of x is mapped to only one value of y.

Hence, in this problem, graph w represents a function.

Answer:

[see below]

Step-by-step explanation:

Use the Pythagorean Theorem.

[tex]a^2+b^2=c^2[/tex]

'c' will be the hypotenuse.

The hypotenuse is 15 cm.  One of the legs is 5 cm.

[tex]5^2+b^2=15^2\\\\25 + b^2 = 225\\\\25-25+b^2=225-25\\\\b^2=200\\\\\sqrt{b^2}=\sqrt{200}\\\\ b=14.1421356237..., -14.1421356237[/tex]

14.1421356237 ≈ 14.1

The other leg should be about 14.1 cm.

Hope this helps.

The length of the other leg is 14.14 cm rounded to two decimal places.

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

Given, The hypotenuse of a right triangle measures 15 cm, and one of its legs measures 5 cm.

We know,

Hypotenuse² = Base² + Adjacent².

Therefore,

15² = 5² + Adjacent².

Adjacent = √(225 - 25).

Adjacent = √200.

Adjacent = 14.14.

Actually Welcome to the Concept of the Quadratic formula.

Since we know that, for

[tex]a {x}^{2} + bx + c = 0[/tex]

For this quadratic equation, the formula is :

[tex] \frac{ - b - + \sqrt{ {b}^{2} } - 4ac }{2a} [/tex]

so we apply it here,

so we get as,

[tex] \frac{ - 5 + - \sqrt{25 - 24} }{6} [/tex]

option C is correct.

Answer:..........

Step-by-step explanation:

Step-by-step explanation:

To find the y intercept we need to find slope first which can be done by taking 2 points and using the slope formula

5 - 10

----------  =   -5/3    

12--9

The slope is -5/3 now we take one point substitute the slope in and find the y intercept

5=-12( -5/3) +b

5= 20+ b

-15 =b

The y-intercept is -15

Answer: The correct option is A: $2.00

Step-by-step explanation:

The question should be:

"The bill at the restaurant was $18.79 estimate the amount to leave as a 10% tip. A. $2.00 B. $3.00 C. $9.00 D. $21.00"

The general case is:

When we have a quantity A (where A is the 100%) the X% of A is:

(X%/100%)*A

In this problem, we have a bill of $18,79 and we want to leave a 10% tip.

Then $18,79 is the 100% we want to see how much is the 10% of $18,79

If we use the above equation we get:

Tip = (10%/100%)*$18,79 = $1,879

The option that approaches the best to this amount is option A, $2.00

Then the tip should be $2

The correct option is A.

Answer: C -7/3

Step-by-step explanation: Slope is rise over run, rise/run, and your line means your slope will be negative. So, you will first count straigt down from your firt point until you reach the line of the second point, which is 7. Next, you would count/run to the point, which is 3. Rise/run = -7/3.

Answer:

$4800

Step-by-step explanation:

Let x be the C.P of the painting.

Profit=10% of x

Profit=[tex]\frac{10}{100}\times x=\frac{10x}{100}[/tex]

If S.P increase by 240 then

Profit=15% of x=[tex]\frac{15x}{100}[/tex]

For first case

S.P=C.P+ Profit

S.P=x+10x/100

S.P=[tex]\frac{100x+10x}{100}=\frac{110}{100}x[/tex]

For second case

New S.P[tex]=x+\frac{15}{100}x[/tex]

         =[tex]\frac{115}{100}x[/tex]

According to question

[tex]240+S.P=\frac{115}{100}x[/tex]

[tex]240+\frac{110x}{100}=\frac{115}{100}x[/tex]

[tex]240=\frac{115}{100}x-\frac{110x}{100}[/tex]

[tex]240=\frac{115x-110x}{100}[/tex]

[tex]240=\frac{5}{100}x[/tex]

[tex]x=\frac{240\times 100}{5}[/tex]

[tex]x=4800[/tex]

Hence, the C.P of the painting=$4800
