What is the y-intercept in the equation y = 4x - 3?

Answer:

A

Step-by-step explanation:

[tex]\frac{1}{5} (150x-80y+50-50x-25y+20)[/tex]

step 1 apply the 1/5 to everything that inside of the parenthesis

[tex]\frac{150x}{5} =30x\\\\\frac{-80y}{5} =-16y\\\\\frac{50}{5} =10\\\\\frac{-50x}{5} =-10x\\\\\frac{-25y}{5} =-5y\\\\\frac{20}{5} =4[/tex]

we now have 30x - 16y + 10 - 10x - 5y + 4

Step 2 combine like terms

30x - 10x = 20x

-16y - 5y = - 21y

10 + 4 = 14

we're left with 20x - 21y + 14 Which corresponds with answer choice A

Answer:

20x-21y+14

Step-by-step explanation:

1/5(150x-80y+50-50x-25y+20) is equal to 1/5(150x) + 1/5(-80y) + 1/5(50) + 1/5 (-50x) + 1/5(-25y) + 1/5(20)

So if we simplify, we would have 30x + (-16y) + 10 + (-10x) + (-5y) + 4, or 30x -16y + 10 -10x -5y + 4

When organizing the values by variable, the equation would look like this -

30x - 10x -16y -5y + 10 + 4

Combining like terms will result in 20x -21y + 14.

Answer:

The surface area is 177 square inches

Step-by-step explanation:

Given

[tex]Length = 10[/tex]

[tex]Width = 3[/tex]

[tex]Height = 4\frac{1}{2}[/tex]

Required

The surface area

This is calculated as:

[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]

So, we have:

[tex]Area = 2 * (10* 3+ 10* 4\frac{1}{2}+ 3* 4\frac{1}{2})[/tex]

[tex]Area = 2 * (30+ 45+ 13\frac{1}{2})[/tex]

[tex]Area = 2 * (88\frac{1}{2})[/tex]

[tex]Area = 177[/tex]

9. Multiply the money he has by the portion he spent:

75 x 3/5 = (75 x3)/5 = 225/5 = 45

He spent $45

10. First rewrite 4 1/8 as an improper fraction

33/8

Now multiply by 1/3:

33/8 x 1/3 = (33 x1) /(8 x 3) = 33/24 = 1 3/8

Answer:

The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.

Step-by-step explanation:

The data given is

               Today               Five Years Ago

X`                 81                           85

σ              14.5                        8.5

n                81                          36

The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.

The test statistics that will be used is

Z= x1-x2/ √σ₁²/ n₁ + σ₂²/n₂

Z=  81- 85/ √14.5² /81 + 8.5² /36

z= -4/√210.25/81+ 72.25/36

z= -4/2.1454

z= -1.8644

Answer:

2.46212121 miles

-

convert a mile measurement to a foot measurement, multiply the length by the conversion ratio. The length in feet is equal to the miles multiplied by 5,280

The mile, sometimes the international mile to distinguish it from other miles, is the British imperial unit and the US customary unit, both systems are based on the older English unit of length equal to 5,280 feet, or 1,760 yards, and standardised as exactly 1,609.344 metres by international agreement in 1959

To convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.

To convert a distance of 13,000 feet to miles, you can multiply it by the conversion factor of 1 mile divided by 5,280 feet.

We know that

1 mile= 5280 feet

Then we will use the ratio of 1 mile / 5,280 feet, the numerator 1 represents the equivalent distance in miles, and the denominator 5,280 represents the equivalent distance in feet.

So, 13000 feet x 1 mile/ 5280 feet

= 13000/ 5280

= 2.462121212121212 miles

Therefore, to convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.

Answer:

1920 cm³

Step-by-step explanation:

V = w · h · l

V = 8 · 14 · 10

V = 1120 cm³

Now for the smaller one.

V = w · h · l

V = 8 · 10 · 10

V = 800 cm³

1120 cm³ + 800 cm³

1920 cm³

Answer:

1920 cm ^3

Step-by-step explanation:

find the volume of the 2 cuboids seperatly.

bigger one: LXWXH --> 8 X 14 X 10 = 1120

smaller one: LXWXH --> 10X10X8 = 800

add them up

1120 + 800 = 1920 cm

Answer:

(-6, -4)

Step-by-step explanation:

Original coordinates: (6, -4)

POINT S IS 12 UNITS TO THE LEFT OF POINT P.

There are multiple ways to solve this, but I will explain the easiest way.

We can subtract 12 from the x-coordinate.

This because the x-axis runs RIGHT and LEFT.

The y-axis runs UP and DOWN.

6 - 12 = -6

The y-coordinate stays the same.

The new coordinates are: (-6, -4).

7- The volume of a rectangular pyramid is:

We just have to substitute the values:

8- The volume of a cone is:

Let's substitute the values and solve:

If you want to round it, the answer will be:

9- The volume of a square pyramid V = a²h / 3, where a is the base and h the height.

So,

10- The volume of the cone is V = hπr² / 3

Then,

9 is the diameter, which is the radius two times. As you see, what the formula asks is for the radius at the second power -multiplied by itself two times-, but if we get the diameter value instead, there is no need to multiply it. The diameter stays the same.

If you want to round it to the nearest tenth, the answer is:
