The given lines are intersecting but not perpendicular.

What is intersecting lines?

In Euclidean geometry, the empty set, a point, or another line can intersect another line. For instance, computer graphics, motion planning, and collision detection can all benefit from differentiating these cases and locating the intersection.

Given:

          y = 6x - 2

2x - 12y = 24

⇒  6x - y = 2         ..(1)

2x - 12y = 24       ..(2)

Multiply second equation by 3,

6x - 36y = 72           ..(3)

Subtract equation (1) from equation (3).

     6x - 12y = 24

-    6x -    y  = 2

_______________

          -11y = 22

    y = -2

Plug y = -2 in equation (1)

6x - (-2) = 2

 6x + 2 = 2

       6x = 2 - 2

       6x = 0

         x = 0

The solution of the given system is (0, -2).

Hence, the given lines are intersecting but not perpendicular.

Answer:

B

Step-by-step explanation:

The equation of variable is m= -9, x = -2, b = 10, w = 4. There was a final answer of solving this in equation.

Solving equation of m,

4m - 5 = - 41

4m =  - 41 + 5

4m = -36

m = -36 / 4

m = - 9.

Solving equation of x.

- 11 = 1 - 6x

-11 -1 = -6x

-12 = -6x

- 12/6 = x

x = -2

Solving equation of b.

4/5b + 5 = 13

4/5b = 13 - 5

4/5b = 8

b = 8 x 5/4

b = 40/4

b = 10

Solving equation of w.

- 1/2w - 8 = -6

-1/2w = -6 + 8

-1/2w = 2

w = 2 x 2/1

w = 4/1

w = 4

Hence. the answer is -9, -2, 10, 4.

The number of miles each car travels in 1 hour is 16 1/4 miles

From the question, we have the following parameters that can be used in our computation:

Given rate. 97 1/2 miles in 3/2 hours

The number of miles each car travels in 1 hour can be calculated as

Number of miles = 97 1/2 miles/3/2 hours * 1 hour

This gives

Number of miles = 97 1/2 miles/3/2

Evaluate the quotient

So, we have the following representation

Number of miles = 16 1/4 miles

Therefore,

The limit of a function in mathematics is a key idea in calculus and analysis regarding the behavior of that function close to a specific input.

Informally, a function f gives each input x an output f(x). If f(x) approaches L as x approaches input p, we say that the function has a limit L at that location. More specifically, any input that is sufficiently close to p when f is applied forces the output value arbitrarily close to L.

The concept of limit is specifically used in the various definitions of continuity. Roughly speaking, a function is continuous if all of its limits agree with the values of the function. The term "limit" is also used in the definition of the mathematical term "derivative," which in one-variable calculus refers to the maximum value of the slope of secant lines on a function's graph.

The probability that the sum is a multiple of three is 0.2778

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event will not occur and 1 indicating that the event will definitely occur.

If a pair of six-sided dice is rolled, and the sum is recorded, then the possible sum is the numbers from (1 + 1) = 2 to (6 + 6) = 12.

From 1 to 12, the multiples of 3 are 3, 6, 9, and 12. These can be resulted from having the following dice rolled.

3 : 1 & 2, 2 & 1

6 : 1 & 5, 2 & 4, 3 & 3, 4 & 2, 5 & 1

9 : 3 & 6, 6 & 3

12 : 6 & 6

Since there are 10 possible outcomes wherein the sum is a multiple of 3, and there are (6 x 6) total outcomes, then the probability is

p = 10 / 36 = 0.2778

Hence, the probability that this sum is a multiple of three is 0.2778.

All the possible values of each expression is given as an inequality as;

3 < y - x < 6

We are given the inequalities of the domain and range as;

6 < x < 7

10 < y < 12

Thus, we can say that the maximum value of y-x will be the difference between the maximum value of y and the minimum value of x to give;

(y - x)max = 12 - 6

(y - x)max = 6

Similarly, minimum value of y - x will be the difference between the maximum value of x and the minimum value of y to give;

(y - x)min = 10 - 7

(y - x)min = 3

Answer: True

Step-by-step explanation:

A recursive algorithm to find a^2n, where a is a real number and n is a positive integer, is as follows:

This algorithm uses the property of exponentiation that a^(2n) = (a^n)^2, and divides the problem of finding a^2n into a smaller subproblem of finding a^n. It takes advantage of the recursive nature of the problem by calling the same algorithm with a smaller value of n.

The time complexity of this algorithm is O(log n) as it divides the problem into half at each recursive step.

It should be noticed that this algorithm assumes that the input value of n is positive, otherwise it would be necessary to add a check for a negative value or zero.

Answer: D. "none."

Step-by-step explanation: The complement of "at least one" is "none."

When we say "at least one," it means that there is a minimum of one of something. Therefore, the complement of "at least one" refers to the opposite condition, where there is no occurrence of that something.

Here's an example. Suppose you have a bag of marbles, and you are told that the bag contains at least one red marble. The complement of "at least one red marble" would mean that there are no red marbles in the bag.

The wrong with following piece of mRNA, TACCAGGATCACTTTGCCA is that it contains T and not U. So, option(D) is right choice here.

Messenger RNA (mRNA) is present in DNA. DNA uses four bases in its code, adenine (A), guanine (G), cytosine (C) and thymine (T). RNA also uses four bases. However, instead of using "T" as DNA, it uses uracil (U). So, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'. A strand of DNA is a template strand that has a nucleotide sequence on it that is read by RNA polymerases. Rna polymerase reads the template strand and encodes the m-RNA using the base-pairing rule. According to the rule, adenine pairs with thymine and guanosine with cytosine. So if the template DNA reads TAC GTT ACG, RNA polymerase will read it as AUG CAA UGC. Since no thymine is present in RNA, it will code for U instead of T.

Answer:

y = 7x

Step-by-step explanation:

I answered a similar question posted by you. The logic is the same so you should be able to figure it out

To graph y = 7x, use a graphing calculator.

If you wish to plot manually, take 2 values of x, find the y value using the equation and draw a straight line through those points

Point 1: When x = 0, y = 7 · 0 = 0. So (0,0) is one point

Point 2: When x = 1, y = 7; y = 7 · 1 = 7 So (7, 1) is the second point.

Draw a straight line through these points and you get your graph

The polynomial function:

f(x) = x³ - 125

Can be factorized into

f(x) = (x - 5)*(x² + 1*x + 5)

We want to factorize the polynomial expression:

f(x) = x³ - 125

And we want to factorize this in the following way:

f(x) = (x + a)*(x² + bx + c)

Trivially, 5 is a root of the function:

f(5) = 5³ - 125 = 0

Then we can write the function as:

f(x) = (x - 5)*(x² + bx + c)

And that must be equal to the original function:

(x - 5)*(x² + bx + c) = x³ - 125

Expanding the left side we will get:

x³ - 5x² + bx² + cx - 5bx - 5c = x³ - 125

x³ + (b - 5)x² + (c - 5b)x - 5c = x³ - 125

Then we can write the equations:

b - 5 = 0

c - 5b = 0

-c*5 = 125

Then we have:

c = 5

And with this equation:

c - 5b = 0

5 - 5b = 0

5 = 5b

5/5 = b

1  = b

Then the function can be written as:

f(x) = (x - 5)*(x² + 1*x + 5)
