​George has $3 in his savings account. He then adds $4 per day to the account. Let y represent the total amount in the account after x days.

Which equation represents this situation in the form of y=mx+b ?

Question 9 options:

y = 4x + 3


y = 3x + 4


y = 3/4x - 3


y = 4/3x - 4

We can write

n = 10a + b

where a and b belong to {1, 2, 3, …, 9}.

Swapping the digits produces a new number

n' = 10b + a

and adding 3 to this number makes up 2n,

n' + 3 = 2n

or

(10b + a) + 3 = 2 (10a + b)

so that

19a - 8b = 3

Since we want n to be the smallest possible 2-digit number that meets the criteria, let's start with a = 1. Then solving for b, we find

19 - 8b = 3

16 = 8b

b = 2

So, the number we're looking for is n = 12.

Just to confirm, swapping the digits gives 21, and 21 + 3 = 24 = 2•12.

Answer:

2nd option

Step-by-step explanation:

The ratios on both sides must be equal

[tex]\frac{15}{6}[/tex] ( divide numerator/ denominator by 3 )

= [tex]\frac{5}{2}[/tex] ≠ [tex]\frac{3}{2}[/tex] , then not a proportion

[tex]\frac{4}{5}[/tex] ( multiply numerator/ denominator by 3 )

= [tex]\frac{12}{15}[/tex] , this is a proportion

[tex]\frac{9}{21}[/tex] ( divide numerator/ denominator by 3 )

= [tex]\frac{3}{7}[/tex] ≠ [tex]\frac{6}{7}[/tex] , then not a proportion

[tex]\frac{10}{16}[/tex] ( divide numerator/ denominator by 2 )

= [tex]\frac{5}{8}[/tex] ≠ [tex]\frac{2}{8}[/tex] , then not a proportion

Answer:

$140

Step-by-step explanation:

100/116×$162.40=$140

Answer:

Before the increase it was $136.416.

Step-by-step explanation:

16% of $162.40 is 25.984.

We need to do $162.40 - 25.984 which equals to $136.416.

Answer:

3d+4

Step-by-step explanation:

(5d+6)–(2d+2)

To find the opposite of 2d+2, find the opposite of each term.

5d+6−2d−2

Combine 5d and −2d to get 3d.

3d+6−2

Subtract 2 from 6 to get 4.

3d+4

Answer:

1115.49 feet

Step-by-step explanation:

To convert meters to feet, multiply 340 meters by 3.281 because there are approximately 3.281 feet in 1 meter.

340*3.281= 1115.49

Answer: the slope 4

Step-by-step explanation:

the slop is y^2 - y^1 / x^2 - x^1 = 0 -8 / -1 - - 3 = 8/2 = 4

Answer: No association

Step-by-step explanation:

There is absolutely no pattern going on. This means that the miles ran per week are not really affecting the standing heartbeat. Therefore, I'd say there is no association.

Answer: 7+3/4x >= 31

Step-by-step explanation: 7 more = +7

three - fourths of a number = 3/4 x

no less than = >= (more than or equal to sign)

Answer:

The odds for are 50% and the odds against are 50%.

Step-by-step explanation:

On a die, there is 6 possibilities 2, 3, and 5, are 3 of them.

This means there is a 3/6 chance that it will land on one of those numbers, and there is also a 3/6 chance it will land on 1, 4, or 6.

3/6 is equivalent to 50% and 1/2.

Answer:

x=27/2

Step-by-step explanation:

1/2-1/3x=-4

subtract 1/2 from both sides

1/2+-1/3x -1/2=-4 -1/2

Group like terms

-1/3 ⋅ x +1/2+(-1/2)=-4 -1/2

Combine the fractions

-1/3 ⋅ x+0=-4 -1/2

Convert the integer into a fraction

-1/3 ⋅ x=-8/2 -1/2

Combine.

-1/3 ⋅ x= -9/2

Isolate the x:

-1/3x ⋅ 3/-1= -9/2 ⋅ 3/-1

1x=-9/2 ⋅ 3/-1

x= -9 ⋅ -3/2

x=27/2 as your answer

Answer:

12

Step-by-step explanation:

The Constant (K) is equal to 8/2 aka 0.25 making the formula now y = 0.25 × x

We have y as 3 so

3 = 0.25 × x we take the 0.25 to the other side by dividing on both sides.. this makes it cancel out on the right.

x is now equal to 3/0.25 which is 12. X = 12

Is the answer 9 for the last x

Answer:

tan x = 3/4

Step-by-step explanation:

The hypotenuse of the triangle is 10 ft.

For angle x, the opposite leg is 6 ft, and the adjacent leg is 8 ft.

tan A = opp/adj

tan x = 6 ft / 8 ft

tan x = 3/4

Answer:

[tex]\frac{9x}{y^3}[/tex]

Step-by-step explanation:

[tex]\frac{\left(3x^2y^4\right)^3}{3x^5y^{15}}[/tex]

[tex](3x^2y^4)^3 : 3^3x^6y^1^2[/tex]

= [tex]\frac{3^3x^6y^{12}}{3x^5y^{15}}[/tex]

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

= [tex]\frac{3^2x^6y^{12}}{x^5y^{15}}[/tex]

= [tex]\frac{x^{6} }{x^{5} } : x[/tex]

= [tex]\frac{3^2xy^{12}}{y^{15}}[/tex]

=  [tex]\frac{y^{12} }{y^{15} } : \frac{1}{3{y} }[/tex]
