Answer:

There is nothing wrong with the answer obtained

Step-by-step explanation:

Given the equation :

Y = mx + b

-2 = 3(4) + b

-2 = 12 + b

-14 = b

The correct calculation :

Y = mx + b

-2 = 3(4) + b

-2 = 12 + b

Subtract 12 from both sides

-2 - 12 = 12 + b - 12

-14 = b

Based on the details of the question given, the intercept, b is - 14 ;

Hence, there is nothing wrong with the answer

Answer:

1/10. 10% Since there are 30 pens, there are 3 black ones.

Answer:

The fraction of the black pens in the pack is [tex]\frac{3}{30}[/tex]

The percent of the black pens in the pack is 10%

Step-by-step explanation:

If 1/10 pens are black, we can use this same proportion to find how many black pens will be in the pack of 30.

Using this, there will be 3/30 pens that will be black, since 3/30 is equivalent to 1/10 when reduced.

So, the fraction of the black pens in the pack is [tex]\frac{3}{30}[/tex]

To find the percent, divide 3 by 30:

3/30

= 0.1 (10 percent)

So, the percent of the black pens in the pack is 10%

Answer:

175 miles

Step-by-step explanation:

Average of 25 miles per gallon of fuel

Miles : gallons = 25 : 1

Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates

Let x = number miles

Miles : gallons = x : 7

To find x

25 : 1 = x : 7

25/1 = x/7

Cross product

25*7 = 1*x

175 = x

x = 175 miles

Number miles = 175

Answer:

3 layers

Step-by-step explanation:

Given

[tex]L = 1cm[/tex] --- side length of the cube

Each layer = 2 * 2 cube

[tex]Volume = 24cm^3[/tex]

Required

Determine the number of layers

First, we calculate the volume of each layer:

The length of the layer is:

[tex]Length = 2 * L[/tex]

[tex]Length = 2 * 1cm[/tex]

[tex]Length = 2cm[/tex]

Next, we calculate the volume of each layer:

[tex]Volume = Length^3[/tex]

[tex]Volume = (2cm)^3[/tex]

[tex]Volume = 8cm^3[/tex]

The number of layer is calculated by dividing the volume of the tower by the volume of each layer

[tex]Layers = \frac{24cm^3}{8cm^3}[/tex]

[tex]Layers = 3[/tex]

yuhh

Slope of  line that passes through two points:  [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(2, -5)    ⇒    x₁ = 2,  y₁ = -5

(-4, 1)      ⇒   x₂ = -4,  y₂ = 1

[tex]\bold{m=\dfrac{1-(-5)}{-4-2}=\dfrac{1+5}{-6}=-1}[/tex]

Any line with a slope of -1 is parallel the line that passes through the points

(2, –5) and (–4, 1)

Answer: 64.8 mph

Step-by-step explanation:

Given

Arriving time is 6 hours

return time is 4 hours

The average speed of returning 81 mph

Distance traveled while returning

[tex]\Rightarrow d=81\times 4=324\ miles[/tex]

the average speed of the entire trip is

[tex]\Rightarrow v_{avg}=\dfrac{2\times 324}{6+4}=\dfrac{648}{10}=64.8\ mph[/tex]
