Answer:

3y = 5x - 24

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

3y = 5x + 2 ( divide through by 3 )

y = [tex]\frac{5}{3}[/tex] x + [tex]\frac{2}{3}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{5}{3}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{5}{3}[/tex] x + c ← is the partial equation of the parallel line

to find c substitute (6, 2 ) into the partial equation

2 = 10 + c ⇒ c = 2 - 10 = - 8

y = [tex]\frac{5}{3}[/tex] x - 8 ← equation in slope- intercept form

multiply through by 3 to clear the fraction

3y = 5x - 24 ← equation of parallel line

Answer:

[tex]\bold{\dfrac{9}{11}}[/tex]

Step-by-step explanation:

I will use the dot notation for multiplication

We have
[tex]\dfrac{3}{11}\cdot \dfrac{3}{4}\cdot \:4[/tex]

Convert 4 to a fraction:
[tex]4=\dfrac{4}{1}[/tex]

Therefore

[tex]\dfrac{3}{11}\cdot \dfrac{3}{4}\cdot \:4 \\\\= \dfrac{3}{11}\cdot \dfrac{3}{4}\cdot \dfrac{\cancel {4}}{1}\\\\[/tex]

Cross-cancel common factor 4
[tex]=\dfrac{3}{11}\cdot \dfrac{3}{1}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \dfrac{a}{b}\cdot \dfrac{c}{d}=\dfrac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]

15th row of the Pascal's Triangle is used to expand [tex](2x+10y)^{15}[/tex]. There will be 16 terms in the expansion.

Pascal's Triangle is used to find the co-efficient for binomial expansions.

The nth row of the Pascal's Triangle gives the coefficients in the expansion of binomial expressions of degree n. For example, in the expansion of [tex](x+y)^2[/tex] , the binomial coefficients are 1,2,1 which is given in the 2nd row of Pascal's Triangle. Also the expansion has three terms, therefore. The Pascal triangle starts with 0th row consisting of only 1.

Here the given expression is [tex](2x+10y)^{15}[/tex] of degree 15. So its binomial coefficient is given in the 15th row of Pascal's triangle.

The number of terms in the binomial expansion of degree n will be n+1 because the coefficients in nth row will n+1 in number.

Hence there will be 16 terms in the expansion of [tex](2x+10y)^{15}[/tex].

It is found that the intercepts can be found from vertex form, if the graph is hovering above the x axis (k<0).

The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x) At y-axis, we've got x = 0, so putting it will give us the y-intercept. Thus, y-intercept of y = f(x) is y = f(0)

If a quadratic equation is written in the form y=a(x-h)² + k

therefore it is called to be in vertex form. It is called so because when you plot this equation's graph, we will see vertex point(peak point) is on (h,k)

To convert the given equation to vertex form, We will take out coefficient of x squared, and then inside the bracket, we try to make perfect square like situation.

To find the intercepts, if the graph is hovering above the x axis (k<0) then there will be no real solutions for the x intercept.

Answer:

The area will decrease by 9%.

Step-by-step explanation:

The area of a rectange is given by the formula below.

[tex]\boxed{\text{Area of rectangle}= \text{length}×\text{width}}[/tex]

Let the original length and width of the rectangle be L and W respectively.

Start by finding the original area:

Original dimensions

Length= L= 100%L

Width= W= 100%W

Original area= LW

Let's find the dimensions of the new rectangle in terms of L and W.

New dimensions

Length= (100% +30%)L= 130%L

Width= (100%-30%)W= 70%W

New area

[tex] = \frac{130}{100} L \times \frac{70}{100} W[/tex]

[tex] = \frac{91}{100} LW[/tex]

= 91% LW

Comparing the new area with the original area:

100% LW- 91% LW= 9% LW

∴ The area will decrease by 9%.

*Note that percentage is equivalent to dividing a number by 100.

Juan multiplied the bases together, and added the power together, therefore, his solution is wrong.

Power is the result of multiplying same number for n number of times. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

The correct solution,

3² ∙ 9⁴

= 3² ∙ (3²)⁴

= 3²  ∙ 3⁸

= 3¹⁰

Hence, Juan multiplied the bases together, and added the power together, therefore, his solution is wrong.

Answer:

720cm³

Step-by-step explanation:

Volume of a cylinder is given by Base Area (A) x Height (h)

or V = Ah

Volume of cylinder A = 18 x 5 = 90 cm³

Base Area A = πr² where r is the radius of the base

For cylinder A, if radius = rₐ

Area = π x (rₐ)² = 18

We can see that cylinder B has twice the height of cylinder A. That means cylinder B radius is twice the radius of cylinder A

So radius of cylinder B = 2 x rₐ = 2rₐ

Base Area of Cylinder B = π x (2rₐ)² = 4π(rₐ)² = 4 x Base Area of cylinder A = 4 x 18 = 72

So while the heights are in the ration 1:2, the base areas are in the ratio 1:4 because the areas are directly proportional to the square of the radius

Hence Volume of Cylinder B = 72 x 10 = 720 cm³

Another way to look at this is that the volume of cylinder B = 8 (2 x 2 x2) times the volume of cylinder A = 8 x 90 = 720cm³

Maria's capital gain is 55.2%.

Here, we are given that Maria purchased 1,000 shares of stock for $35.50 per share in 2003.

Thus, the total cost price of these shares = 1000 × 35.5

= $35500

In 2007, she sold all of the stocks for $55.10 per share

Thus, the total selling price of these shares = 1000 × 55.1

= $55100

Now, absolute gain = selling price - cost price

Here, Maria's absolute gain will be-

= 55100 - 35500

= 19600

Now, her percentage gain will be given by-

Gain % = absolute gain/ initial value × 100

= 19600/35500 × 100

= 55.2

Thus, Maria's capital gain is 55.2%.

Step-by-step explanation:

The answer is in the screenshot.

The integers are 14 and 16.

Let the integers be represented by x and x+2.

It was stated that the consecutive even integers such that 6 times the smaller integer is 36 more than 3 times the larger integer.

This will be:

6(x) = 3(x + 2) + 36

6x = 3x + 6 + 36

6x = 3x + 42

6x - 3x = 32

3x = 42

Divide

3x/3 = 42/3

x = 14.

The larger number will be:

= x + 2

= 14 + 2

When Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime then the total amount he earned is $232.2

Given,

The amount he earns in an hour = $5.40

Total number of hours he worked =40 hours

The amount he earns = 5.40×40 = $216

Overtime hours = 2 hours

Overtime payment per hour= 5.40×1.5= $8.1

The amount he earns for overtime = 2×8.1= $16.2

The total amount he earned = 216+16.2= $232.2

Mass is the property of a body that measure its inertia. It is taken as the measure of the amount of material it contains and have weight in gravitational field

Mass is also refers as the weight of an object. It is measured in grams (g) and kilograms (kg)

Radius of an object is defined as a straight line from the centre of a circular object to the circumference of the circular object

According to the data given of five planets  

(a) The planet which has greatest mass is Mars that is 6.42 x 1023 kg

Radius of a given object can be calculated by dividing the diameter of the given object by 2.

The probability that the students are enrolled in less than three courses is 0.5

P(A) = 0.5

The probability that the students are taking a math class is 0.33

P(B) = 0.33

if 71% of students are either enrolled in less than three courses or taking a math course.

P(A ∪ B) = 0.71

We need to find the percentage of students that are enrolled in less than three courses and taking a math course.

i.e., we need to find P(A ∩ B)

We know that, P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

P(A ∩ B) = 0.5 + 0.33 - 0.71

P(A ∩ B) = 0.12
