R90° transformation results in an image point that is (6, -8).

The plane is divided into four infinite areas known as quadrants, each of which is bounded by two half-axes, using two-dimensional Cartesian axes.

These are commonly numbered from 1 to 4, and are denoted by Roman numerals: the coordinates for I are I (+, +), II (-, +), III (-, -), and IV (+, -).

We are aware that there are four quadrants: I (x, y), II (-x, y), III (-x, -y), and IV (-x, -y) (x, -y)

We can infer that the points are in quadrant III from the supplied point, which is (-6, -8). (-x, -y).

Now, if we turn right 90 degrees and enter sector IV (x, -y), the supplied point will change to (6, -8)

hence, following the transformation of R90°, we have the image point is (6, -8).

Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line.

Now, from the given problem, we see that we have two parallel lines with a transversal crossing them Thus, we can say that the two given angles are corresponding angles and as such they are congruent. Thus;

in this problem we have a vertical line

The equation of a vertical line is equal to the x-coordinate of the point that passes through it

so

in this case

the equation of the line is

x=-1

Answer:

Step-by-step explanation:

the equation is written in slope intercept form

y= mx + b with m= slope and b= y-intercept

so in your equation

y=2/3x + 1,

the slope is 2/3 and the y-intercept is (0,1)

slope is also known as rise/run

so to move from one point to another, starting at (0,1) (since you know that point is on the line) you would move up 2 units and to the left 3 units.

Answer:

P = 80 units

Explanation:

Let's label some points in the triangle as:

Since the sides of the triangles are tangent to the circumference, we can write the following relationships:

XC = YC

AZ = AY

BX = ZB

So, the length of the missing side XC is equal to:

XC = YC = 14

On the other hand, the length of AB is the sum of the length of AZ and ZB, so we can calculate ZB as:

AB = AZ + ZB

26 = AY + ZB

26 = 18 + ZB

26 - 18 = ZB

8 = ZB

Because AZ and AY have the same length.

Finally, the measure of BX is equal to:

BX = ZB

BX = 8

Therefore, the perimeter of the triangle is:

Perimeter = AY + YC + AZ + ZB + BX + XC

Perimeter = 18 + 14 + 18 + 8 + 8 + 14

Perimeter = 80

So, the answer is 80 units.

Consequently, it costs $62.70 to make cupcakes for two hours.

By making use of functions, We have: n(h) = 3h, The cost in terms of hours h is given by C(3h) = 60+1.35h, and Lisa's cost for making cupcakes for 2 hours is $62.70

According to the question, Lisa makes 3 dozen cupcakes an hour. To calculate how many she makes in h hours, we will apply the equality postulate as stated.

3 dozens = 1 hour

Hour = n(h)

Cross Multiplying,

n(h) × 1 = 3×h

n(h) = 3h

Therefore, n(h) = 3h is the function that predicts the number of cupcakes Lisa produces in h hours.

We shall locate the composite function C(n(h)) to obtain the cost function in hours.

C(n(h)) = C(3h) (3h)

If C(n) = 60 + 0.45n, then

By replacing n with 3h in the function as indicated, C(3h) is obtained;

C(3h) = 60+0.45(3h) (3h)

C(3h) = 60+1.35h

Thus, 60+1.35h is the cost function expressed in hours.

We will change h = 2 into the calculation C(h) = 60+1.35h to obtain the cost of baking cupcakes for 2 hours.

C(2) = 60+1.35(2) (2)

C(2) = 60+2.70

C(2) = 62.70

Consequently, it costs $62.70 to make cupcakes for two hours.

The given system of equation:

y = 3x - 5 (1)

y = -6x + 4 (2)

We can solve the system of equation by using elimination method :

Elimination Method: In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Subtract the equation (1) & (2)

So, we get x = 1

Substitute the value of x in the equation (1)

y = (-2)

So, the solution of the system of equations are : (x,y) = (1,-2)

Answer: (x,y) = (1,-2)

Mr. Thompson weighs 260 pounds and he loses 4 pounds each month.

The equation will be :

w = 260 - 4m

where w is the weight after m months

when w = 220 pounds, the number of months will be :

220 = 260 - 4m

4m = 260 - 220

4m = 40

m = 40/4

m = 10

The answer is 10 months

The exponential equation which represents the amount of raw sugar t hours after the process begins is; A = 1,000 (0.8)^(t/5).

It follows from the task content that the amount of raw sugar left after the process begins is to be determined according to the information given.

Since, 20% of the available raw sugar is changed to a refined sugar every 5 hrs, it follows that only 80% of the raw sugar is left after each successive time interval period.

Hence, the exponential model of the situation is such that;

A = 1,000(0.8)^(t/5).

Where t = number of hours after the process begins.

Therefore, the required equation is; A = 1,000(0.8)^(t/5).

The margin of error can be used to provide the data that has to do with the amount of sampling error that would be in a given data statistic.

We would have to calculate the amount of error using the data that we have below.

We have the following values

number n = 10

mean u = 49

standard deviation sd = 2

The level of confidence c i = 80% = 0.80

  x = 3

Step-by-step explanation:

Given the sequence x, 7, 11, 15, ... 399, where 399 is the 100th term, you want to know the first term, x.

The differences of the first few terms are ...

  11 -7 = 4

  15 -11 = 4

This suggests an arithmetic sequence with a common difference of 4.

The first term, x, will be 4 less than the second term:

  x +4 = 7

  x = 7 -4 = 3

The value of x is 3.

The n-th term of an arithmetic sequence with first term a1 = 3 and common difference d = 4 is ...

  an = a1 +d(n -1)

  an = 3 +4(n -1) = 4n -1
