Answer:

4x-y+1=0

Step-by-step explanation:

here,given equation of a line id

4x-y-2=0.. eqn(i)

equation of any line parallel to line (i) is

4x-y+k=0...eqn(ii)

since, the line(ii) passes through (1,5)[replacing x=1 and y=5 in eqn(ii), we get]

4*1-5+k=0

or, 4-5+k=0

or,-1+k=0

•°•k=1

substituting the value of k=1 in eqn(ii),

4x-y+1=0 is the required equation of the line.

When the domain is {-1,2,4} , the range of the function y =-3x+6 is {-6,0,9}

Given,

The function y= -3x+6

The domain of the function is the complete set of all possible input for the function.

The domain = {-1,2,4}

The range of the function is the complete set of all possible output for the function.

Substitute the values in the function

f(-1)= -3×-1+6

=3+6

= 9

f(2)= -3×2+6

=-6+6

= 0

f(4)= -3×4+6

=-12+6

=-6

So, -6,0 and 9 the possible output of the function y= -3x+6

The range of the function y= -3x+6 is  {-6,0,9}

Hence, When the domain is {-1,2,4} , the range of the function y =-3x+6 is {-6,0,9}

Step-by-step explanation:

The sum of all the even integers between 99 and 301 is 20200

To find the sum of even integers between 99 and 301, we will use the arithmetic progressions(AP). The even numbers can be considered as an AP with common difference 2.

In this case, the first even integer will be 100 and the last even integer will be 300.

nth term of the AP = first term + (n-1) x common difference

               ⇒    300 = 100 + (n-1) x 2

Therefore, n = (200 + 2 )/2 = 101

That is, there are 101 even integers between 99 and 301.

Sum of the 'n' terms in an AP = n/2 ( first term + last term)

                                                = 101/2 (300+100)

                                                = 20200

Thus sum of all the even integers between 99 and 301 = 20200

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Ms. Barcht's savings account can be modeled with the expression

50 + 25x

Mrs. Greene's savings account can be modeled with the expression

75x

Since the question is how many weeks Mrs. Greene will have more money than Ms. Bracht. we use an inequality to contain the all the solutions.

Mrs.Greene > Ms. Bracht

75x > 25x + 50

Answer:

The answer would be C. 75x>25x+50

Step-by-step explanation:

The answer would be C. because Ms. Barcht started with $50 and deposits $25 every week while Mrs. Greene saves $75 a week. 7 days is a week so lets multiply $25 x 2 (2 weeks). Ms. Barcht would have $100 by the end of 2 weeks and Mrs. Greene would have $150 by the end of 2 weeks because $75x2 is $150

The perimeter is a measure of a polygon that describes the distance around the boundaries of a shape.

Perimeter Formula

The perimeter of a rectangle is equal to [tex]l + l + w + w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width. This can be simplified to [tex]2l+2w[/tex]. Now, we can plug in the expression we are given for width and length.

Simplifying the Expression

The expression above does accurately depict the perimeter, but it should be simplified to make the expression easier to understand and use.

First, distribute the 2 inside the parentheses.

The next step is to combine like terms. Like terms are terms that have the same power and variable. For example, 2r and 14r are like terms.

This is the simplified expression and the final answer.

1.35 divided by 12 = 0.1125

Answer:

$0.11 per egg

Step-by-step explanation:

unit cost means how much each one costs

there are 12 eggs in a dozen

so all you have to do is divide $1.35 by 12

which equals $0.1125

but money is only counted by the hundredths place so we have to round

and that would be $0.11

The area  rate of change of side of square is 8 cm/s;

dA/dt = 112 cm²/s;

Area = (r)²; where r is the side of square;

dA/dt = (dA/dr)(dr/dt);

dA/dr = 2r and dA/dt = 112 cm²/s;

Therefore; dr/dt = 112/2r at r = 7;

dr/dt = 112/14 = 8 cm/s;

Rate of change of side of square is 8 cm/s;

area is the quantity that expresses the extent of a area on the plane or on a curved floor. The location of a aircraft region or plane place refers to the location of a shape or planar lamina, at the same time as surface place refers to the vicinity of an open floor or the boundary of a 3-dimensional object.

Step-by-step explanation:

Answer:

The solution is x = 8.

Step-by-step explanation:

Amount in First Oak Bank is $87.84 than at River Point after 2 years.

Simple interest is the interest obtained over the principal amount on a certain rate.

Compound interest is the amount of interest which is calculated on the principal amount as well as the amount accumulated over the previous period.

First oak bank is simple with 6% interest.

Final amount in simple interest, A = P(1 + rt), where P is the principal amount , r is the interest rate and t is the number of years.

A = 450 (1 + (0.06 × 2)) = $504

River point bank is 2% compounded annually

Final amount in compound interest, A = P(1 + r/n)^(nt), where, P is the principal amount, r is the interest rate, t is the number of years and n is the number of times interest compounded annually.

P = 850 - 450 = 400

n = 1, since compounding is only 1 time in a year

A = 400(1 + 0.02)² = $416.16

Amount which is more in First oak is $504 - $416.16 = $87.84

Hence the amount more in the First oak account is $87.84.

Answer: The measure of angle 3 is 50 degrees.

Step-by-step explanation:

We know that angle 2 is 130 degrees.

Angle 1 and angle 2 are verticle angles which means that they are across and equal to each other.

So angle 1 and angle 2 are 130 degrees.

Add up both angle 1 and angle 2, 130 + 130 = 260.

Now, all of these angles add up to be 360 degrees in total as they make a circle and there are 360 degrees in one.

Subtract 260 from 360, 360 - 260 = 100.

Since both angle 3 and angle 4 are also verticle angles we need to split the 100 degrees evenly, 100 ÷ 2 = 50.

So, angle 3 is 50 degrees.

Let the width of the garden be b and its length is 9 feet less than 3 times the width.

Length = 3b-9 ...(1)

The perimeter of the garden = 63

We need to find the system of equations that represents is the dimensions of the rectangular garden.

Perimeter = 2(l+b)

63 = 2(3b-9+b)  [from equation (1)]

31.5 = (3b-9+b)

31.5 = (4b-9)

31.5+9 = 4b.....(2)

b = 10.12

Hence, the equations are showsn in equation (1) and (2).
