Answer:

y = 1/2x + 1

Step-by-step explanation:

m = 1/2

Slope-intercept:

y - y1 = m(x - x1)

y - 3 = 1/2(x - 4)

y - 3 = 1/2x - 2

y = 1/2x + 1

Answer:

333 ft squared

Step-by-step explanation:

18 x 18.5 = 333

Answer: 12 inches

Step-by-step explanation:

This is a square shaped mirror which means that it takes the shape of a square.

All sides on a square are equal and because the way the find the area of a square is to multiple the Length by the Width, you would be squaring the same number to find the area.

Length of each side = √area

= √144

= 12 inches

Step-by-step explanation:

Total Depreciation: 60.24%

Total depreciation: $9,759.50

Car Value after 6 years: $6,440.50

The element is remaining 146.6 grams after 7 minutes, to the nearest 10th of a gram.

An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.

The exponential decay function:

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Given:

An element with mass 630 grams decays by 18.8% per minute.

That means, 18.8% = 0.188

Here, we will use the exponential decay function.

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Here,

A₀ = 630 grams

r = 0.188

x = 7 minutes

Substituting the values to the formula,

A₇ = 630(1-0.188)⁷

A₇ = 630(0.812)⁷

A₇ = 630(0.23275134787)

A₇ = 146.633

A₇ = 146.6 grams.

Therefore, element is remaining 146.6 grams.

Answer:

1.)   ((a+1)^3)+(x^3)  = a^3 + 3a^2 + 3a + x^3 + 1

2.)  ((y-2)^3)-27  =   (y^2-y + 7) x ( y - 5 )

3.)   ((a-b)^3)+b^3  = a (a^2 - 3ab + 3b^2 )

4.)   (8x^3)+((x-y)^3)  =  9x^3 -3x^2 y + 3xy^2 - y^3

5.)   (27a^3)-((a-b)^3) = 26a^3 + 3a^2 b - 3ab^2 + b^3

5) factor = (a+b)(a+b)^ 2    if a is squared and if b is cubed and moved over to = 0 then we can find (a+b)(a+b)^2 but in all cases of quadratics you can set (x -1 ) = 1 and (x-1 ) = 1  so they are always positive. Which is the same if they start of negative.

For question 5 we have a factor solved (a+b)(a+b)^ 2

Which means the same as this expansion

Step-by-step explanation:

I don't know how to explain it

Answer:

a.

capacity of car = 14 gallons

consumption of fuel in one day = 0.6 gallons

consumption of fuel in 14 days = 14 x 0.6 = 8.4 gallons

fuel remaining in car = 14 - 8.4 = 5.6 gallons

so they can drive the car without warning.

b.

consumption of fuel in one day = 0.6 gallons

consumption of fuel in 25 days = 25 x 0.6 = 15 gallons

fuel remaining in car = 14 - 15 = -1 gallons

so they can't drive the car without warning.

c.

the expression 14 - 0.6t represents remaining fuel in the vehicle, where t represents number of days.

d.

14 - 0.6t = 1.5

or - 0.6t = 1.5 - 14 = - 12.5

or t = -12.5 / - 0.6

or t = 20.8333 days

so he can drive 20 days without warning.                                                                                         E.

14 - 0.6t < 1.5

or t < 20.8333

here t represents number of days car can drive without warning light.

Step-by-step explanation:

The inequality is  

The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

14 gallons-1.5 gallons=12.5 gallons  

we know that

If the remaining fuel is greater than  1.5 gallons Diego's father can drive the car without the warning light coming on  

so

Let

x ----> the number of days

 ----> inequality that represent the situation

Solve for x

The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

Step-by-step explanation:

when dividing numbers with exponents with the same base, subtract the exponents.

[tex]\frac{8^{7} }{8^{7} }[/tex]

7 - 7 = 0

[tex]\frac{8^{7} }{8^{7} }[/tex] = [tex]8^{0}[/tex]

anything to the power of 0 is 1

[tex]8^{0}[/tex]= 1

Answer:

1

Step-by-step explanation:

Any number divided by itself equals 1 with the exception of 0 since 0/0 is undefined.

8^7 is not equal to zero, so without doing any calculations or using any other rules, we know that

8^7/8^7 = 1

We can use the rule of exponents for dividing powers.

Rule:

[tex] \dfrac{a^m}{a^n} = a^{m - n} [/tex]

Here we have a = 8, m = 7, and n = 7.

Applying the rule, we get

[tex] \dfrac{8^7}{a^7} = 8^{7 - 7} = 8^0 [/tex]

Another rule of exponents:

[tex] a^0 = 1 [/tex]

We the zero power rule now:

[tex] 8^0 = 1 [/tex]

Therefore,

[tex] \dfrac{8^7}{a^7} = 1 [/tex]

Answer:

The inverse  is ±sqrt(100-x)

Step-by-step explanation:

To find the inverse, exchange x and y

x = 100 -y^2

Solve for y

Subtract 100 from each side

x - 100 = -y^2

Divide by -1

-x +100 = y^2

Take the square root of each side

±sqrt(100-x) = sqrt(y^2)

±sqrt(100-x) =y

The inverse  is ±sqrt(100-x)
