Given:

The equation of a line is:

[tex]y-1=4x[/tex]

A line parallel to the above line passes through the point P(2,5).

To find:

The equation of the parallel line.

Solution:

The slope intercept form of a line is:

[tex]y=mx+b[/tex]         ...(i)

Where, m is the slope and b is the y-intercept.

The given equation is:

[tex]y-1=4x[/tex]

It can be rewritten as

[tex]y=4x+1[/tex]        ...(ii)

On comparing (i) and (ii), we get

[tex]m=4[/tex]

It means the slope of the given line is 4.

We know that the slopes of two perpendicular lines are equal. So, the slope of the required parallel line is also 4.

The parallel line passes through the point P(2,5) with slope 4, thus the equation of the parallel line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-5=4(x-2)[/tex]

[tex]y-5=4x-8[/tex]

[tex]y=4x-8+5[/tex]

[tex]y=4x-3[/tex]

Therefore, the equation of the required parallel line is [tex]y=4x-3[/tex].

Answer:

65.60

Step-by-step explanation:

Formula :

Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2

Solution :

Distance between two points = √(30−−22)2+(−25−15)2(30--22)2+(-25-15)2

= √522+(−40)2522+(-40)2

= √2704+16002704+1600

= √43044304 = 65.6049

Answer:

A. 0.088

B. 0.048

C. 1.83 times

Step-by-step explanation:

From the question given above, the following data were obtained:

Green (G) = 4

Yellow (Y) = 5

Total = 4 + 5 = 9

A. Determination of the probability of selecting three green marbles with replacement.

Green (G) = 4

Yellow (Y) = 5

Total = 9

P(1st G) = 4/9

P(2nd G) = 4/9

P(3rd G) = 4/9

P(all G) = P(1st G) × P(2nd G) × P(3rd G)

P(all G) = 4/9 × 4/9 × 4/9

P(all G) = 64/729

P(all G) = 0.088

B. Determination of the probability of selecting three green marbles without replacement.

Green (G) = 4

Yellow (Y) = 5

Total = 9

P(1st G) = 4/9

P(2nd G) = 3/8

P(3rd G) = 2/7

P(all G) = P(1st G) × P(2nd G) × P(3rd G)

P(all G) = 4/9 × 3/8 × 2/7

P(all G) = 24/504

P(all G) = 0.048

C. Comparing probability of replacement and without replacement.

P(all G with replacement) = A = 0.088

P(all G without replacement) = B = 0.048

A/B = 0.088/0.048

A/B = 1.83

Cross multiply

A = 1.83 × B

Thus,

P(all G with replacement) = 1.83 × P(all G without replacement)

Answer:

35 members

Step-by-step explanation:

In a tennis club the ratio number of junior members : number of senior members is 7 : 10

From the above ratio

Number of junior member = 7

Number of senior members = 10

There are 18 more senior members than junior members.

S = 18 + j

10 + 18 = 28 senior members

Hence,

Total number of members = 28 senior members + 7 junior members

= 35 members

Answer:

24

Step-by-step explanation:

34 messages per 12 minutes

68 is just 34 mulitplied by 2.

it would take you twice as long because there are twice as many messages.

12 minuted multipled by 2 is 24.

It would take you 24 minutes to send 34 messages.

Answer:

24 minutes

Step-by-step explanation:

34/12

34*2=68

12*2=24

Answer:

x=7

Step-by-step explanation:

In a parallelogram, you know that parallel sides are equal in length, therefore, x+4 must equal 5x-24.  From there you solve for x.

x+4 = 5x-24

28 = 4x  (subtract x from both sides and add 24 to both sides)

7=x   (28 divided by 4 is 7).

Answer:

Here you go, please mark brainliest for my effort! Thanks!

Step-by-step explanation:

5x - 24 and x + 4 are equal in length, so set them equal to each other.

5x - 24 = x + 4

Subtract x on both sides.

4x - 24 = 4

Now, add 24 to both sides.

4x = 28

Finally, divide both sides by 4.

x = 7

So the answer is x = 7

Answer:

50 students from each grade

Step-by-step explanation:

If we get the similar amount of people from each and every grade so this would represent the percentage occur from each grade this determine the number of people who vote per grade and represent that how much would the vote for student comes

Also 50 is easily divisible by 750

Therefore the above represent the answer

Answer:

m = 5

Step-by-step explanation:

distance traveled D= 16m^2+100 miles

speed, S= 8m+10 mph

time taken, T = 2m hours

We know that  D = S×T

⇒ 16m^2+100 = (8m+10)× 2m

⇒ 16m^2+100 = 16m^2+ 20m

⇒ 20m = 100

⇒ m = 5

Therefore, the value of m is 5

Answer:

(y+6)(y-1)

Step-by-step explanation:

literally factorising.

y^2 x -6 = -6y^2

u need two numbers that multiply to make -6 and add them together to make +5 which is +6 and -1.

Answer:

p = 6, q = - 1 , or p = - 1, q = 6

Step-by-step explanation:

Factorise the quadratic expression on the left side

y² + 5y - 6

Consider the factors of the constant term (- 6) which sum to give the coefficient of the y- term (+ 5)

The factors are + 6 and - 1 , since

6 × - 1 = - 6 and 6 - 1 = + 5 , then

y² + 5y - 6

= (y + 6)(y - 1) = (y - 1)(y + 6)

Compare to (y + p)(y + q) , then

p = 6, q = - 1 or p = - 1, q = 6

The constructions that are crucial to draw a circle inscribed on the given equilateral triangle are:

There can be many different ways, one can include arc way, one can include angle bisector and perpendicular, and we can even try to discover some. But usually, (for the angle bisector and perpendiculars), we do the following:

Drawing random arcs isn't gonna help mostly neither unspecific line segments. Drawing angle bisectors of the triangle and perpendiculars is one of the part.

Answer:

4 bags will be required.

Step-by-step explanation:

Patio is in the shape of a parallelogram.

Formula for the area of a parallelogram is,

Area = [tex](\text{Base})(\text{Height})[/tex]

        = 16.2 × 12

        = 194.4 square feet

∵ 50 square feet area is covered by 1 bag of concrete mix.

∴ 1 square feet area will be covered by [tex]\frac{1}{50}[/tex] bag of concrete mix

∴ 194.4 square feet patio will require the concrete mix = [tex]\frac{194.4}{50}[/tex]

                                                                                           = 3.888

                                                                                           ≈ 4 bags

Therefore, 4 bags of concrete mix will be required by Dave to add a new patio.
