When a system of linear equations has a
solution.... what am I actually finding when I
solve for x and y?

Answer: 56 785 is written as fifty six thousand, seven hundred and eight five. The number 406 090 is written as four hundred and six thousand and ninety. Numbers with seven, eight or nine digits, are millions. 46 758 442 is forty six million, seven hundred and fifty eight thousand, four hundred and forty two.

Step-by-step explanation:

The number would be 794 in figure form which represents seven hundred and ninety-four.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

Calculating the number of quantities for an object or the Number of things left in the container are only two examples of the types of mathematical operations that utilize the Number System.

We have to write the number seven hundred and ninety-four in figures

As per the given statement, the expression would be:

⇒ 700 + 94

⇒ 794

Therefore, the number seven hundred and ninety-four in figure form would be 794.

Answer:

y= -x-3

Step-by-step explanation:

A line is parallel to another line if their slope is the same. In this case the slope is -1 (-x is basically -1x). So far we have y=-x+b (We dont know what b is yet). next we can insert the coordinate back into the equation y=-x+b where 1 is the y and -4 is the x.

We get...

y= -x+b

1= -(-4)+b

1=4+b

b=-3

Our final equation is y=-x-3

Answer:

At least 15 weeks

Step-by-step explanation:

If Ella needs at least $360, she will have to save her $25 constantly for about 15 weeks.

25*15=375, which is more than 360, so she will have leftover money.

Answer:

2 weeks + 1day

Step-by-step explanation:

7 days a week. 7 + 7 = 14

25 x 14 = $350, missing another 10 dollars.

25 x 15(adding a extra day) = 275.

in change, you have 15 dollars left.

Answer:

[tex]1320\ \text{feet}[/tex]

Step-by-step explanation:

The distance Thomas walked to the nearest gas station is [tex]\dfrac{1}{4}\ \text{mile}[/tex].

The conversion factor for miles to feet is

[tex]1\ \text{mile}=5280\ \text{feet}[/tex]

So

[tex]\dfrac{1}{4}\ \text{mile}=\dfrac{1}{4}\times 5280[/tex]

[tex]=1320\ \text{feet}[/tex]

Hence, Thomas had to walk [tex]1320\ \text{feet}[/tex] to get to the nearest gas station.

Answer: 10 sq units

Step-by-step explanation:

Area of triangle: 1/2 x b x h

1/2 x 2 x 2 = 2

Area of the left triangle is 2 sq units

1/2 x 4 x 2 = 4

Area of the right triangle is 4 sq units

Area of square: l x w

2 x 2 = 4

Area of square is 4 sq units

Area of figure: A of square + A of r tri. + A of left tri.

4 + 4 + 2 = 10

The area of the figure is 10 sq units.

Answer:

The percent of interest is 12.3% per year

Step-by-step explanation:

According to the question Elwood invested 5000 $ in market account

The market account gives the compound interest annually

let p be the interest per year then

At the end of 1st year

amount =(1+0.p) x 5000  = 1.p x 5000

similarly at the end of 2nd year

amount =(1+0.p) x(1+0.p)x 5000  = [tex](1.p)^{2}[/tex] x 5000

similarly at the end of 3rd year

amount = 7100 $ = [tex](1.p)^3[/tex] x 5000

⇒ [tex]\frac{71}{50}[/tex] = [tex](1.p)^3[/tex]  

1.392 =  [tex](1.p)^3[/tex]

on further solving we get

1.p = [tex](1.42)^{1/3}[/tex] = 1.123

thus 1.p = 1 + 0.p = 1.123

thus p = 0.123

thus the percent of interest is 12.3% per year

Answer:

drop down 1 a slower rate per year

drop down 2 670

Step-by-step explanation:

as in three years you get $7100

you take that and subtract it by your starting amount (5000)

7100-5000= 2100

then divide 2100 by the number of years (3)

to get your annual rate of 700$

then you take the 8 year total and subtract it from your 3 year total

10350-7100= 3250

Then divide that by 5 because that how many years it has been

to get the annual rate of 650

making the 5 year rate slower.

The to find the average rate over all 8 year you take 10350 and subtract it from your starting number 5000

10350-5000= 5350

then take 5350 and divide it by the number of years (8)

you then get you average rate of 668.75

668.75=670

Hope this helps!

Answer:

[tex]h(0) = 10[/tex]

[tex]h(4) = NaN[/tex] (Not a number)

Step-by-step explanation:

According to the statement, we get the following piecewise function:

[tex]h(x) = \left\{ \begin{array}{ccc}3\cdot x -4,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,x < 0\\2\cdot x^{2}-3\cdot x + 10,\,\,\,\,\, 0\le x < 4\\2^{x}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, x\ge 5\end{array}[/tex]

The value of the function when [tex]x = 0[/tex] is:

[tex]h(0) = 2\cdot (0)^{3}-3\cdot (0) +10[/tex]

[tex]h(0) = 10[/tex]

The value of the function when [tex]x = 4[/tex] is undefined, since 4 is out of any of the intervals covered by [tex]h(x)[/tex].

[tex]h(4) = NaN[/tex] (Not a number)

Answer: h(0)=10

h(4)=30

Answer:

see explanation

Step-by-step explanation:

Using the product rule

Given

y = f(x)g(x) , then

[tex]\frac{dy}{dx}[/tex] = f(x).g'(x) + g(x).f'(x) ← product rule

(a)

let

f(x) = (3x - 1)³ , then using the chain rule

f'(x) = 3(3x - 1)² × [tex]\frac{d}{dx}[/tex](3x - 1) = 3(3x - 1)² × 3 = 9(3x - 1)²

let

g(x) = 2x + 5 ⇒ g'(x) = 2

Then

[tex]\frac{dy}{dx}[/tex] = (3x - 1)³ . 2 + (2x + 5) × 9(3x - 1)²

    = 2(3x - 1)³ +9(3x - 1)²(2x + 5) ← factor out (3x - 1)²

    = (3x - 1)²[ 2(3x - 1) + 9(2x + 5) ]

    = (3x - 1)² [ 6x - 2 + 18x + 45 ]

    = (3x - 1)²(24x + 43)

--------------------------------------------------------------

(b)

let

f(x) = 3x - 2 ⇒ f'(x) = 3

let

g(x) = 2x² + 3 ⇒ g'(x) = 4x

Then

[tex]\frac{dy}{dx}[/tex] = (3x - 2).4x + (2x² + 3). 3 ← distribute parenthesis

    = 12x² - 8x + 6x² + 9

    = 12x² - 8x + 9

Answer:

X=-2

Step-by-step explanation:

Let's solve your equation step-by-step.

4(4x−4)+x+4=−46

Step 1: Simplify both sides of the equation.

4(4x−4)+x+4=−46

(4)(4x)+(4)(−4)+x+4=−46(Distribute)

16x+−16+x+4=−46

(16x+x)+(−16+4)=−46(Combine Like Terms)

17x+−12=−46

17x−12=−46

Step 2: Add 12 to both sides.

17x−12+12=−46+12

17x=−34

Step 3: Divide both sides by 17.

17x
