The equation to illustrate the information regarding the temperature it the temperature rose 2 degrees every hour is -3 + 2h.

It should be noted that an equation is used to show the relationship between the variables.

In this case, when janelle woke up it was -3 degrees Fahrenheit outside.as the morning progressed,the temperature rose 2 degrees every hour.

Let the number if hours be represented by h

Therefore, the equation to illustrate the information will be -3 + 2h

here h = number of hours.

Answer:

$4.00

Step-by-step explanation:

make a proportion

50/125=x/1000

1000(50/125)=x

8(50)=x

400=x

400pennies=$4.00

or solve like this

50/125= 0.4 pennies per gram (p/g)

0.4p/g

0.4p/g*1000g=400p=$4.00

A sales tax is one that is levied on both the selling of products and services to businesses and on the purchases of those same goods and services by consumers. It's a form of consumption tax, which means it charges consumers for their purchases. Because sales taxes are typically passed on to customers at the moment of sale, it is classified as a consumption tax.

Solving the question:

Cost of the book = 9.95

Sale tax rate = 9%

Sale tax amount on 9.95 = 9.95/(9/100) = 9.12

Therefore, the final cost of the book is  = 9.12

A stem and leaf plot is a simple kind of graph that is made out of the numbers themselves.

It is a means of displaying the main features of a distribution.

If a stem and leaf plot is turned on its side.

it will resemble a bar graph or histogram and provide similar visual information.

Answer:

A stem and leaf plot is a simple kind of graph that is made out of the numbers by their selves.

The midpoint of AR is (1/2 , 1).

Let the points be:

A(0,0) = (x₁,y₁)

B(1,2) = (x₂,y₂)

Midpoint = (x₁₊x₂/2) , (y₁₊y₂/2)

A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway. In addition, the halfway is reached if a line is drawn to divide the line that connects these two places.

= (0₊1/2) , (0₊2/2)

=(1/2 , 2/2)

= (1/2 , 1)

hence the midpoint of the number line is  (1/2 , 1).

The time taken by Franklin to make a 200 sq. foot cement patio = 14 hours

The time taken by Scott to make a 200 sq. foot cement patio = 10 hours.

Let x be the number of hours it would take Franklin and Scott to make the patio together.

Then x = 14 x 10 / (14 + 10)

⇒ 1 / x = (14+10)/(14 x 10)

⇒ 1/x = 1/14 +1/10

This is the equation to find the number of hours taken by Franklin and Scott together.

Answer:

Step-by-step explanation:

The bank can borrow $6440 based on the $7000 deposit.

The following deposit amount: $7000

Because the reserve rate is 8%, the bank will reserve 8% of the 7000. The remaining funds can be lent by the bank.

7000 × (8/100) = amount set aside

= $560

Thus, the reserve deposit is $560.

Amount the bank is willing to lend = 7000 - 560 = $6440

Thus, the bank can lend $6440 based on a deposit of $7000.

If the equation be y = x² + 4 then the inverse function be [tex]f^{-1} (x)=[/tex] ± [tex]\sqrt{x - 4[/tex].

An inverse function, also known as an anti function, is a function that can be reversed into another function. Simply put, if any function " f " takes x to y, then its inverse will take y to x. The inverse function is denoted by f-1 or F-1 if the function is denoted by ' f ' or ' F '.

Let the equation be y = x² + 4    

then the function be f(x) = x² + 4

y = x² + 4

⇒ x = y² + 4

simplifying the above equation, we get

x - 4 = y²

√y² = √x - 4

The value of y = ± √x - 4

Therefore, the inverse function be [tex]f^{-1} (x) =[/tex] ±√x - 4

the temperature will be 2.5 degrees per second.

We are given the data:

Seconds       Temperature (°F)

0                            75

10                          100

20                         125

30                         150

We need to find the temperature in degrees per second.

So, we get that:

Seconds       Temperature (°F)                    degrees / sec

0                            75                                            Nil

10                          100                           (100 - 75) / (10 - 0) = 2.5

20                         125                         (125 - 100) / (20 - 10) = 2.5      

30                         150                         (150 - 125) / (30 - 20) = 2.5            

Therefore, the temperature will be 2.5 degrees per second.

Answer: The answer for this question is x=1

Step-by-step explanation: -3(2x-3)=-6x+9 first you multiply -3x with 2x and -3 to get -6x+9=-6x+9 then subtract nine from both sides to leaves -6x=-6x then you divide -6 on both sides and you get x=1.

Any value of x makes the equation true. All real numbers

Interval Notation: (−∞,∞)

Because if you solve it

-3(2x-3)=-6x+9

distribute

-6x + 9 = -6x + 9

subtract 9 from both sides

-6x = -6x

simplify

0 = 0

Step-by-step explanation:

so, pre-image is then doing the opposite :

going up 2 units and left 4 units.

up/down changes y, left/right changes x.

up = positive y direction

down = negative y direction

right = positive x direction

left = negative x direction

just as indicated by the coordinate axes.

so,

going up 2 units = adding 2 to y

going left 4 units = subtracting 4 from x

giving us as pre-image point A

(4 - 4, -5 + 2) = (0, -3)

The numerical expression using commutative property of multiplication that is equivalent to 2⁸ is 2² x 2² x 2² x 2² = 256.

Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division. The result of a multiplication operation is called a product.

Now the given exponent is,

2⁸

Now, 8 can be written as using associative property of addition,

8 = 2 + 2 + 2 + 2

Thus we can write,

2⁸ = 2^( 2 + 2 + 2 + 2 )

Using exponential property

x^(a + b) = x^a . x^b

Thus we get,

2⁸ = 2^2 . 2^2 . 2^2 . 2^2

Thus numerical expression for 2^8 = 2^2 . 2^2 . 2^2 . 2^2

Solving we get,

2^8 = 4 x 4 x 4 x 4 = 256

Thus, the numerical expression using exponential property of multiplication that is equivalent to 2⁸ is 2² x 2² x 2² x 2² = 256.
