Raul opened a savings account with $2900. Each week, d, Raul pays the dog sitter $20 from his savings account. Write a function, f (d) , that is equal to the amount if money in the account after raul pays the dog sitter each week.

Answer:

Option A

Step-by-step explanation:

The answer to this question is option A or "Yes because it can be written as a/b and a and b are integers and b =0." Any number that can be written as a fraction is a rational number. In this case repeating decimals can be written as a fraction using different types of algebraic methods making it a rational number.

if a  is 1 more than b it can be expressed as so:

a=b+1

b+1=a

b^2+1=a^2

b^2=a^2-1

b=a-1

if b if 1 then a is 2

b+1=a

-a+b=-1

a-b=1

a=2, b=1

a=b+1

a+b=3

1+2=3

What I did I reduced the equation and got y by itself. The new equation would be y=3/2x+11/2x. I started plugging in points. I put the equation on a graph and found those points on the graph.

Answer:

Step-by-step explanation:

(-7 + 3)/(6 + 6) = -4/12 = -1/3

y + 3 = -1/3(x + 6)

y + 3 = -1/3x - 2

y = -1/3x - 5

The angle if an angle measures 86° less than the measure of its supplementary angle is 133.

Supplementary angles are two angles whose measures add up to 180° .

Supplementary Angles

Let the angle be "x".

Its supplementary angle is "180-x"

Equation:

180 - x - x = 86

180 - 2x = 86

2x = 180 - 86

2x = 94

x = 47

Angle x = 47 degrees

supplementary angle is "180-x"

= 180 -47

= 133

Hence , If an angle is 86° smaller than its supplementary angle, the angle is 133°.

Answer:600 miles

Step-by-step explanation:

Hello!  

So you know that 348 miles is equal to 58% so you want to figure out what 1% of the total trip is

348 / 58 = 6

You know that 1% of the trip is 6 miles so now to figure out what the total trip is you multiply 6 by 100

6 * 100 = 600

So you know that the total length of the trip is 600 miles long.

50,000 * 60%= 30,000

If Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her salary on expenses each year, then Sandy spends $30,000 on expenses.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Given that, Engineer Sandy earns a salary of $50000 per year. If Sandy spends each year 60% of her income on expenses,

We have to find the amount Sandy has to spend on expenses,

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

The amount spend on the expenses is,

Expenses = 60% of the salary

Expenses =60/100 × $50000

Expenses = 30,000

Thus, if Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her salary on expenses each year, then Sandy spends $30,000 on expenses.

The equation of the exponential function will be:

[tex]f\:\left(x\right)\:=\:ab^x[/tex]

          [tex]=\:\frac{3}{2}\left(2\right)^x[/tex]

Step-by-step explanation:

Given the table

Day         Bacteria

1               3

2              6

3              12

4              24

5              48

as

and

so it is indeed an exponential function

As we know that the exponential function is of the form

[tex]f\:\left(x\right)\:=\:ab^x[/tex]

As we know that the y-intercept of [tex]f\:\left(x\right)\:=\:ab^x[/tex] is (0, a).

so

[tex]\frac{3}{a}=2[/tex]        ∵ common ratio = successor y-value ÷ previos y-value

[tex]a=\frac{3}{2}[/tex]

so the value of a will be: 3/2

We also know that the common factor i.e. multiplier is 2 in this table, we know the value for b is 2.

Therefore, the equation of the exponential function will be:

[tex]f\:\left(x\right)\:=\:ab^x[/tex]

          [tex]=\:\frac{3}{2}\left(2\right)^x[/tex]

Answer:

Cost of one shirt = $ 30

Step-by-step explanation:

Let cost of 1 shirt = s

Cost of 1 hat  = h

A shopper bought 6 shirts and 8 hats for $700.

6s + 8h = 700      -------------------(I)

A shopper bought 9 shirts and 6 hats for $660

9s + 6h = 660    -----------------(II)

Multiply equation (I) with 9 and multiply equation (II) with (-6) and then add. SO, now 's' will be eliminated and we can find the value of 'h'

(I) * 9                54s + 72h  = 6300

(II)*(-6)            -54s  - 36h = - 3960   {Now add}

                                 36h = 2340

                                     h = 2340/36

                                     h = 65

Cost of one hat  =  $ 65

Substitute h = 65 in equation (I)

6s + 8 * 65 = 700

6s  + 520   = 700

            6s = 700 - 520

            6s = 180

               s = 180/6

               s = 30

Cost of one shirt = $ 30

Answer: One shirt is $30

Step-by-step explanation: Have a great day

I'm pretty sure the answer is 1/15 or 4/60 because the whole carpet measures 60m and the covered part's area is 4m and that would be 4/60 but simplified 1/15.  Sorry if this is wrong!

To find the fraction of the carpet covered by the rug, we need to determine the area of the rug and divide it by the total area of the carpet.

The area of the square rug can be calculated by squaring its side length: 2m x 2m = 4m². The total area of the rectangular carpet can be found by multiplying its length and width: [tex]12m x 5m = 60m²[/tex]. To find the fraction, divide the area of the rug by the area of the carpet: 4m² / 60m².

To simplify the fraction, we can find the greatest common divisor (GCD) of 4 and 60, which is 4. Dividing both the numerator and denominator by the GCD, we get: [tex]4m² ÷ 4 / 60m² ÷ 4 = 1m² / 15m²[/tex] . Therefore, the fraction of the carpet covered by the rug is 1/15, which means that 1/15th of the carpet is covered by the rug.

Answer:

1+1=magelan

Answer:

b and d

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 6) and (x₂, y₂ ) = (- 2, 2) ← 2 points on the line

m = [tex]\frac{2-6}{-2+3}[/tex] = - 4

Using (a, b ) = (- 3, 6 ), then

y - 6 = - 4(x - (- 3)), that is

y - 6 = - 4(x + 3) → d

Using (a, b ) = (- 2, 2 ), then

y - 2 = - 4(x - (- 2)) , that is

y - 2 = - 4(x + 2) →b
