Remember that the standard form of a line equation is y = mx + b.   Since you need a line that is parallel to y = 5x - 2, the first thing to do is use the same slope (m), which is 5 in this case.

The new line would look like this:  y = 5x + b.  I use "b" instead of -2, since we'll calculate a "b" for the new line by substituting the given point of (2, -1) into y = 5x + b.

 -1 = 5*(2) + b

 b = -11  

The parallel line that goes through (2,-1) is y = 5x - 11

The new line is the blue, on the right.  Note that it is parallel to the original (green) line and also intersects at  (2, -1).  (Each chart is is 0.5 unit).

Answer:

Cost of 1 rose bush = x = $5

Cost of 1 geraniums = y = $2

Step-by-step explanation:

DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same store.

Let us represent:

Cost of 1 rose bush = x

Cost of 1 geraniums = y

DeShawn spent $13 on 1 rose bush and 4 geraniums.

x + 4y = 13..... Equation 1

x = 13 - 4y

Mike spent $56 on 10 rose bushes and 3 geraniums.

10x + 3y = 56....... Equation 2

We substitute 13 - 4y for x in Equation 2

10(13 - 4y) + 3y = 56

130 - 40y + 3y = 56

Collect like terms

- 40y + 3y = 56 - 130

-37y = -74

y = -74/37

y = $2

Solving for x

x = 13 - 4y

x = _13 - 4 × $2

x = $13 - $8

x = $5

Therefore,

Cost of 1 rose bush = x = $5

Cost of 1 geraniums = y = $2

The beach, the parking lot and the refreshment stand are illustrations of similar triangles.

(a) The distance between the spot and the parking lot

Represent this distance with d.

So, the equivalent ratio is:

[tex]\mathbf{32:d = d : 18}[/tex]

Express as fractions

[tex]\mathbf{\frac {32}d = \frac{d}{ 18}}[/tex]

Cross multiply

[tex]\mathbf{d \times d = 32 \times 18}[/tex]

[tex]\mathbf{d^2 = 576}[/tex]

Take square roots

[tex]\mathbf{d = 24}[/tex]

Hence, the distance between the spot and the parking lot is 24 m

(b) The distance between the refreshment stand and the parking lot

Represent this distance with d.

Using Pythagoras theorem we have:

[tex]\mathbf{d^2 = 32^2 + 24^2}[/tex]

[tex]\mathbf{d^2 = 1600}[/tex]

Take square roots

[tex]\mathbf{d = 40}[/tex]

Hence, the distance between the refreshment stand and the parking lot is 40 m

Answer:

4,188.79 and when its rounded its 4,188.8

Step-by-step explanation:

Volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.

Three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given,

sphere with a diameter of 20 feet

Diameter is two times of radius

Diameter=2Radius

Radius =Diameter/2

Radius = 20/2=10 feet.

Volume of sphere=4/3πr³

π=3.142

Volume of sphere=4/3(3.142)(10)³

=4/3×3.142×1000

=4189.33 cubic feet.

Hence, volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.

Answer:

arcsin0= 0 degrees

arccos0= 90degrees

arctan1= 45 degrees

Step-by-step explanation:

To get arcsin0, let the unknown value be x

sin x = 0

Take arcsin of both sides

arcsin(sinx) = arcsin 0

x = arcsin0

x = 0 degrees

Hence arcsin0 = 0degrees

For cos x = 0

Take arccos of both sides

arccos(cosx) = arccos 0

x = arcscos0

x = 90 degrees

Hence arccos0 = 90degrees

For tan x = 1

Take arctan of both sides

arctan(tanx) = arctan 1

x = arctan1

x = 45 degrees

Hence arctan1 = 45degrees

Answer: The temperature on the 5th day is -14 degrees.

Step-by-step explanation:

If we have a set of N values:

{x₁, x₂, x₃, ..., xₙ}

The mean value of this set is:

M = (x₁ + x₂ + ... + xₙ)/N

Now, we know that the mean temperature for the first 4 days of January is -4°

Then if the temperatures for the first four days are {T₁, T₂, T₃, T₄}

We have:

M₄ = (T₁ + T₂ + T₃ + T₄)/4 = -4°

Where we can replace (T₁ + T₂ + T₃ + T₄) by K

Then:

K/4 = -4°

K = -4°*4 = -16°

Is the sum of the temperatures for the first four days.

Now when we consider the first 5 days, the mean is -6°, and let's define T₅ as the temperature of the fifth day, then we get:

M₅ = -6° = (T₁ + T₂ + T₃ + T₄ + T₅)/5

And we know that:

(T₁ + T₂ + T₃ + T₄) = K = -16°

We can replace that in the above equation to get:

M₅ = (-16° + T₅)/5 = -6°

Now we can solve this for T₅

(-16° + T₅) = 5*(-6°) = -30°

T₅ = -30° + 16° = -14°

T₅ = -14°

The temperature on the 5th day is -14 degrees.

Answer:

D

Step-by-step explanation:

Our answer will be D. We can eliminate choices A and C since they are not products. In other words, they are not multiplying factors together; they are only adding or subtracting.

Answer B does not work, as when it is multiplied out, we get -2x + 16.

When we find the product of D, we distribute the negative and get the correct product, -2x - 16

Answer and explanation:

If Magdala is trying to divide 2.12 by 4 then she would definitely need to change the place value of the dividend(2.12) and the divisor(4). In other words, both numbers need to be whole numbers.

To make 2.12 a whole number, we shift the decimal point two places to the right of the decimal point to get 212. We do same for 4 to get 400, since both numbers have to have their place values adjusted equally.

We divide 212 by 400 to get 0.53

Therefore 2.12 divided by 4= 0.53
