y = 3.5x is the equation that represents y, the total number of hours Tonya works in x days if she continues at the given rate.

Unitary method is a concept in which the value of a single unit is first found out and then multiplied by the necessary value to get the required answer.

Here, we are given that Tonya works 3.5 hours in 1 day.

The total number of days = x

and the total number of hours Tonya works in x days = y

If she works for 3.5 hours in 1 day, in x days she will work-

x x 3.5

= 3.5x hours

Thus, y = 3.5x hours

Hence, y = 3.5x is the equation that represents Tonya's situation.

Answer: It is 32

Step-by-step explanation:

The value of x is 18° and the value of the angles A and B are 73° and 107° respectively.

We are given the angle measurements as:

A = (6x - 35)°

B = (3x + 53)°

We need to solve for x and find the values of A and B

We know that co- interior angles are supplementary.

So, we get that:

A + B = 180°

Substituting the values of A and B in the above equation, we get that:

6 x - 35 + 3 x + 53 = 180

9 x + 18 = 180

9 x = 180 - 18

9 x = 162

x = 162 / 9

x = 18

So, we now get that:

A = (6x - 35)°

A = (6(18) - 35)°

A =(108 - 35)°

A = 73°

B = (3 x + 53)°

B = (3 (18) + 53)°

B = ( 54 + 53 )°

B = 107°

Therefore, we get that the  value of x is 18° and the value of the angles A and B are 73° and 107° respectively.

If TQ = 2x - 6 and RQ = x + 3 then the measure of TQ = 12.

The perpendicular bisector theorem states that if a point is on a segment's perpendicular bisector, it is equidistant from the segment's endpoints.

According to the perpendicular bisector theorem, any point on the perpendicular bisector is equidistant from both ends of the line segment on which it is drawn. If a pillar stands at an angle in the center of a bridge, all of its points will be equidistant from the bridge's end points.

Where, TQ = 2x - 6 and RQ = x + 3

By the Perpendicular Bisector Theorem, RQ = TQ.

2x - 6 = x + 3

x = 9

Substitute the value of x in TQ, we get

TQ = 2(9) - 6

= 18 - 6

= 12

Therefore, the value of TQ = 12.

Sn = a(1 - rⁿ)/(1 - r) is the formula for the sum of a finite number of terms in a geometric series, where is the number of terms, is the first term, and is the common ratio.

The sum of the finite geometric series Σ⁴ n=1 (1/2)ⁿ⁺¹ is 0.46875.

The equation be Sn = a(1 - rⁿ)/(1 - r), where s exists the total, a1 exists the series first term, and r exists the common ratio, is a general formula for estimating the sum of an finite geometric series. The formula a2/a1, where a2 is the second term in the series and a1 is the first term in the series, can be used to determine the common ratio.

Let the sum of the finite geometric series be Σ⁴ n=1 (1/2)ⁿ⁺¹

Σ⁴ n=1 (1/2)ⁿ⁺¹ = (1/2)¹⁺¹ + (1/2)²⁺¹ +(1/2)³⁺¹ + (1/2)⁴⁺¹

simplifying the above equation, we get

= (1/2)² + (1/2)³ + (1/2)⁴ + (1/2)⁴⁺¹

= (1/4) + (1/8) + (1/16) + (1/32)

Where, the first term is a = 1/4

common ratio be r = 1/2

n th term be n = 4

Let the equation be Sn = a(1 - rⁿ)/(1 - r)

substitute the values in the above equation, we get

S4 = (1/4) (1-(1/2)⁴) / (1 - (1/2))

simplifying the above equation, we get

S4 = (1/4) (15/16) × 2 = 15/32 = 0.46875

Therefore, the sum of the finite geometric series Σ⁴ n=1 (1/2)ⁿ⁺¹ is 0.46875.

The given situation shows an arithmetic sequence and the number of sales in the week 50 can be determined by using the nth term formula of arithmetic sequence. The sales in all 50 weeks can be determined by using the formula for sum of finite arithmetic sequence.

An arithmetic sequence is an ordered set of numbers that have a constant difference called a common difference between consecutive terms. Each term is obtained by adding the common difference to the previous term.

In the given situation, the first term (a) is the number of sales to be made in the first week. Hence, a = 10

The common difference (d) is the number added to get the number of sales in the next week. Hence,

d = 1

Hence, in the 2nd week the number of sales should be 11 and in 3rd week it should be 12.

Using the formula for nth term and n = 50,

an=a+(n-1)d

a50=10+(50-1)1

a50=10+(49)1

a50=10+49=59

The formula of finding the sum of the finite arithmetic sequence:

Sn=(n/2)(a1+an)

S50=(50/2)(10+59)

S50=25(69)=1725

Hence, the number of sales in the 50th week is 59 and the total number of sales made in the 50 weeks is 1725.

The solution of the equation is  (-3, 6).

-3c - 3y = -9

5c - 2y = -27

Therefore, using elimination method, the equation can be solved as follows:

multiply equation(ii) by 1.5(3  /2)

-3c - 3y = -9

7.5c - 3y = - 40.5

subtract equation(i) from equation(ii)

10.5c = - 31.5

divide both sides by 10.5

c = -31.5 / 10.5

c = -3

Therefore,

5c - 2y = -27

5(-3) - 2y = -27

-15 - 2y = -27

-2y = -27 + 15

-2y = - 12

divide both sides by -2

y = -12 / -2

y = 6

Answer: Maybe f I'm not sure

Step-by-step explanation:

Answer :f(x) = -5x + 250

Step-by-step explanation:

* Lets  explain how to solve the problem

- In week 10 the manufacturer fixed 200 cars

- In week 15, the manufacturer fixed 175 cars

- the reduction in the number of cars each week is linear

- The form of the linear equation is y = mx + c, where m is the slope of

the line which represent the equation and c is the y-intercept

- The slope of the line m =

 where (x1 , y1) and (x2 , y2) are two points on the line

* Lets solve the problem

- Assume that the weeks' number is x and the cars' number is y

∴ (10 , 200) and (15 , 175) are two points on the line which represent

 the linear equation between the cars' numbers and the weeks

 numbers

∵ Point (x1 , y1) is (10 , 200) and point (x2 , y2) is (15 , 175)

∴ x1 = 10 , x2 = 15 and y1 = 200 and y2 = 175

- Use the rule of the slope above to find m

∴

- Substitute the value of x in the form of the linear equation above

∴ y = -5x + c

- To find c substitute x and y by one the coordinates of one of the

 two points

∵ x = 10 when y = 200

∴ 200 = -5(10) + c

∴ 200 = -50 + c

- Add 50 to both sides

∴ 250 = c

- Substitute the value of c by 250

∴ y = -5x + 250, where the number of cars seen each week is y and

 x is the number of the week

∵ f(x) = y

∴ f(x) = -5x + 250

The ladder can reach 21.17 feet high up of Denise's house.

Given,

The length of ladder Denise used to clean the outside of her second story windows = 24 feet

The distance between the base of the ladder and house = 13 feet

We have to find the height of the house which the ladder can reach:

For that we can use Pythagorean Theorem.

That is,

Hypotenuse² = Altitude² + Base²

Here,

Hypotenuse is the length of the ladder = 24 feet

Altitude is the height of the house ladder can reach = x

Base is the distance between base of the ladder and house = 13 feet

Therefore,

24² = x² + 13²

576 = x² + 169

x² = 576 - 169

x² = 407

Step-by-step explanation:

Find algebraically y values for x = -2 and x = 2 and connect the two points by a line

Equation: y = 3x + 2

For x = -2, y = 3(-2) + 2 = -6 + 2 = -4

For x = 2, y = 3(2) + 2 = 6 + 2 = 8

So the two points are (-2, -4) and (2, 8)

The standard form is y - 1/3x + 1 = 0 for line parallel to y=-3 x+4 through (0,-1)

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

In an equation, parallel lines have the opposite reciprocal slope. In other words, if a line's slope is a positive fraction, its reciprocal slope is negative.

Here given that  y=-3 x+4

Here -3 is the slope and 4 is the y-intercept

To find a parallel line to the following equation, use the opposite reciprocal slope and point, then solve using the point-slope formula.

y - y₁ = m(x - x₁)

We have, m = 1/3, x₁ = 0 and y₁ = -1

y - (-1) = 1/3(x - 0)

y + 1 = 1/3(x - 0

y = 1/3x -1

y - 1/3x + 1

We have the standard form y - 1/3x + 1 = 0 of a line  perpendicular to y = (2/3)x - 1 through (0,6)
