You would want to use the Keep, Change , Flip

method. So you keep the 1/8, change division into multiplication, the flip the 4 into 1/4.

Step-by-step explanation:

(1/8) / 4

(1/8) * (1/4)

answer: 1/32 or 0.03125

Answer:

Dado que f (x) = 50 + 80x, obtenemos m = 80, esto significa que el costo aumenta en 80 cada día

Step-by-step explanation:

La siguiente función representa el costo del alquiler de un auto, en soles, en función del número x de días que se requiera: f(x) = 50 + 80x. ¿Cuánto vale su pendiente y qué representa? a) 130; representa que, por cada día de alquiler, el costo se incrementa en 130 soles. b) 80; representa que, por cada día de alquiler, el costo se incrementa en 80 soles. c) 50; representa que, por cada día de alquiler, el costo se incrementa en 50 soles. d) 30; representa que, por cada día de alquiler, el costo se incrementa en 30 soles

Answer:

La función es una función lineal. Una función lineal tiene la forma y = mx + b, donde m es la tasa de cambio de y con respecto a x, b es el valor de y en x = 0, x es una variable independiente (no depende de otras variables) ey es una variable dependiente (depende de otras variables)

Dado que f (x) = 50 + 80x, obtenemos m = 80, esto significa que el costo aumenta en 80 cada día

Answer:

125 times bigger.

Step-by-step explanation:

A great way to visualize this problem is to think of it as a volume problem itself. Another good way to think about it is to plug in numbers in its place.

Way #1

5*5*5 (or 5^3)=125

Way #2

(2*2*2)=8

(2*5)*(2*5)*(2*5)=1000

1000/8=125

Answer:

y=3/4x+7

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-4,4) and has a slope of 3/4.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was 3/4. So you can right away fill in the equation for a line somewhat to read:

y=3/4x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-4,4). When x of the line is -4, y of the line must be 4.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the 3/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,4).

So, why not plug in for x the number -4 and for y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-4,4). y=mx+b or 4=3/4 × -4+b, or solving for b: b=4-(3/4)(-4). b=7.

hope this answers your question sorry it's soo long i just like writing long stuff have a great day!!

Answer:

Step-by-step explanation:

1. Let the number be x

x^2 + 4x = 21

x^2 + 4x - 21 = 0

Solve the quadratic equation using factorization method

x^2 - 3x + 7x - 21 = 0

x(x - 3) + 7(x - 3) = 0

(x - 3)(x+7) = 0

x - 3 = 0 x + 7 = 0

x = 3 x = -7

The number is either 3 or -7

2. Same solution as number 1

3. Let

Width = x

Length = 2x - 3

Area of the rectangle = 9 square ft

Area of a rectangle = length × width

9 = (2x - 3) (x)

9 = 2x^2 - 3x

2x^2 - 3x - 9 = 0

Solve using quadratic formula

a = 2

b = -3

c = -9

x = -b +or- √b^2 - 4ac / 2a

= -(-3) +or- √(-3)^2 - 4(2)(-9) / 2(2)

= 3 +or- √ 9 - (-72) / 4

= 3 +or- √9 + 72 / 4

= 3 +or- √81 / 4

= 3 +or- 9 / 4

x = (3 + 9)/4 or (3 - 9) / 4

= 12 / 4 or -6 / 4

x = 3 or -3/2

Width can not be a negative value

So,

Width = x = 3 ft

Length = 2x - 3

= 2(3) - 3

= 6 - 3

= 3ft

2.if the sum of the square of the number and 4 time that number is 21 the what is the number?

3. the length of the rectangle is 3 less than twice the width. if the area is 9 square ft, the length and width of the rectangle.

4.given the figure below. find the area of the shaded part of the rectangle if the area of the big but angle is 6 times the area of the unshaded rectangle ​

Unshaded area

Length = 2x

Width = x

Shaded area

Length = (2x+3)

Width = (x+3)

Area of the shaded area = 6 × the unshaded area

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

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

2x^2 = 12x^2 + 36x + 9x + 54

2x^2 = 12x^2 + 45x + 54

12x^2 + 45x + 54 - 2x^2 = 0

10x^2 + 45x + 54 = 0

Answer:

x < .4

Step-by-step explanation:

Please mark Brainliest when you’re able :)

Answer:

Step-by-step explanation:

Step 1 - replace the < with an =

3x + 4.7 = -1.5x + 6.5

Step 2 - subtract 4.7 from each side, and add 1.5x to each side

3x + 1.5x = 6.5 - 4.7

4.5x = 1.8

Step 3 - divide each side by 4.5

x = 1.8/4.5

x = .4

Step 4 - change the = back to <

x < .4

Just make sure when you do it this way you check the answer because if you solved by subtracting 3x and subtracting 6.5 you would end up with .4 = x this .4 < x which is false. So depending what number you get always plug in a number bigger and smaller into the original to check. In this case 0 and 1 work.

3(0) + 4.7 < -1.5(0) + 6.5

4.7 < 6.5 which is true.

3(1)+ 4.7 < -1.5(1) + 6.5

3+4.7 < -1.5 + 6.5

7.7 < 5 which is false

So we know the direction on our < is right.

5/12 is the answer but 1/3 x 5/4 is the reduced version of your question and the alternate form of the answer is 0.416

Answer:

A. 3:4

B. 63 soccer players

Step-by-step explanation:

A. If out of 7 players, 3 wore headbands, then it means 4 out of 7 did not wear headbands.

Ratio of players who wire headbands to those who didn't wear headbands would be 3:4

B. Let x represent number of players who wore headbands

Number of players who didn't wear = 36

Total number of players in the league = number of players who wore headbands + those who didn't wear headbands = x + 36

Let's find x by using the ratio generated in part A.

Ratio of players who wore head bands to players who didn't wear = 3:4 = x:36

[tex] \frac{3}{4} = \frac{x}{36} [/tex]

Cross multiply

[tex] 4*x = 3*36 [/tex]

[tex] 4x = 108 [/tex]

[tex] \frac{4x}{4} = \frac{108}{4} [/tex]

[tex] x = 27 [/tex]

Total number of players in the league = x + 36

Plug in the value of x

= 27 + 36

= 63 players

Answer: 10-7x3+18

Step-by-step explanation:

Ten less so that would be (10-) less than seven would make it (10-7) times a number is the same as 3 would make it (10-7x3) plus 18 would then make it (10-7x3+18)

Answer:

[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{4^{1}}{4^{3}}[/tex]

[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{1}{4^{2}}[/tex]

Step-by-step explanation:

Given

[tex]\dfrac{4^{-3}}{4^{-1}}[/tex]

Required

Choose equivalent expressions

Choosing the first answer:

[tex]\dfrac{4^{-3}}{4^{-1}}[/tex]

Split expressions

[tex]4^{-3} * \frac{1}{4^{-1}}[/tex]

Apply laws of indices: [tex](a^{-b} = \frac{1}{a^b})[/tex]

[tex]\frac{1}{4^3} * \frac{1}{4^{-1}}[/tex]

Apply laws of indices: [tex](a^{-b} = \frac{1}{a^b})[/tex]

[tex]\frac{1}{4^3} * \frac{1}{1/4}[/tex]

[tex]\frac{1}{4^3} * \frac{4^1}{1}[/tex]

[tex]\frac{4^1}{4^3}[/tex]

Hence:

[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{4^{1}}{4^{3}}[/tex]

Choosing the second:

[tex]\dfrac{4^{-3}}{4^{-1}}[/tex]

Apply law of indices: [tex](\frac{a^m}{a^n} = a^{m-n})[/tex]

So,

[tex]\dfrac{4^{-3}}{4^{-1}} = 4^{-3-(-1)}[/tex]

[tex]\dfrac{4^{-3}}{4^{-1}} = 4^{-3+1)}[/tex]

[tex]\dfrac{4^{-3}}{4^{-1}} = 4^{-2}[/tex]

Apply law of indices: [tex](a^{-b} = \frac{1}{a^b})[/tex]

So:

[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{1}{4^{2}}[/tex]
