Find the equation of the line that is parallel to this line and passes through the point (3, -3).

Consider The Line Y = 4x-3.Find The Equation Of The Line That Is Perpendicular To This Line And Passes

Answers

Answer 1

Answer:

perpendicular line: y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]

parallel line: y = 4x - 15

Step-by-step explanation:

Perpendicular line:

A perpendicular line to y = 4x-3 would have a slope that is the negative reciprocal (flip the fraction and add a negative sign). The negative reciprocal of 4 is - [tex]\frac{1}{4}[/tex].

Now that we have our slope, we can plug the given point of (3, -3) into the slope-intercept equation to find b.

-3 = - [tex]\frac{1}{4}[/tex](3) + b

-3 = - [tex]\frac{3}{4}[/tex] + b

Add [tex]\frac{3}{4}[/tex] to each side of the equation to isolate b.

-[tex]\frac{9}{4}[/tex] = b

Now we can write our equation, y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]

Parallel Line:

A parallel line to y = 4x-3 has the same slope. To find the equation, plug the slope and given point (3, -3) into the slope intercept equation and solve for b.

-3 = 4(3) + b

-15 = b

Now you can write the equation, y= 4x -15

Y=-1/4 I believe this is the correct answer....

[tex] {x}^{4} - 6 {x}^{3} + 22 {x}^{2} - 48x + 40[/tex]
find the zeros​

Answers

Answer:

x = 2, 1 + 3i, 1 − 3i

Step-by-step explanation:

Find the Roots (Zeros)

x^4 − 6x^3 + 22x^2 − 48x + 40

Set x^4 − 6x^3 + 22x^2 − 48x + 40 equal to 0. x^4 − 6x^3 + 22x^2 − 48x + 40 = 0

Solve for x.

Factor the left side of the equation.

Factor x^4 − 6x^3 + 22x^2 − 48x + 40 using the rational roots test.

(x − 2) (x^3 − 4x^2 + 14x − 20) = 0

 Factor x^3 − 4x^2 + 14x − 20 using the rational roots test.

(x − 2) (x − 2) (x2 − 2x + 10) = 0

 Combine like factors.

(x − 2)2 (x^2 − 2x + 10) = 0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

(x − 2)^2 = 0

x^2 − 2x + 10 = 0

 Set (x − 2)^2 equal to 0 and solve for x.

Set (x − 2)^2 equal to 0.

 (x − 2)^2 = 0

Solve (x − 2)^2 = 0 for x.

x = 2

 Set x^2 − 2x + 10 equal to 0 and solve for x.

Set x^2 − 2x + 10 equal to 0. x^2 − 2x + 10 = 0

Solve x^2 − 2x + 10 = 0 for x.

Use the quadratic formula to find the solutions.

−b ± (√b^2 − 4 (ac) )/2a

Substitute the values a = 1, b = −2, and c = 10 into the quadratic formula and solve for x.

2 ± (√(−2)^2 − 4 ⋅ (1 ⋅ 10))/2 ⋅ 1

Simplify.

Simplify the numerator.

  x =    2 ± 6i/ 2.1

Multiply 2 by 1

 x =  2 ± 6i/2⋅1

 Simplify

  2 ± 6i/2  

   x = 1 ± 3i

The final answer is the combination of both solutions.

x = 1 + 3i, 1 − 3i

The final solution is all the values that make (x − 2)2 (x2 − 2x + 10) = 0 true.

x = 2, 1 + 3i, 1 − 3i

Aimee is in charge of buying tickets for a trip to the movies. She can buy tickets at the theater or online. At the theater, 8 tickets cost $60. Online, 6 tickets cost $51. Aimee needs to buy 24 tickets. How much money can Aimee save by buying tickets at the lower price? Show your work

Answers

Answer:

Aimee can save $24 by buying tickets at the lower price that is at the theater.

Step-by-step explanation:

First, you need to find the amount she would spent by buying tickets at the theater and online by using a rule of three:

Theater:

60→8

x  ←24

x=(60*24)/8=180

Online:

51→6

x ←24

x=(51*24)/6=204

Now, you need to calculate the difference:

$204-$180=$24

According to this, the answer is that Aimee can save $24 by buying tickets at the lower price that is at the theater.

Answer:

Aimee can save $24 by buying tickets at the lower price that is at the theater.

The solutions to the equation f(x) = g(x) are -2 and 1. Iff and g are graphed on the same coordinate plane, which statement must be true?
The functions will intersect at x = -2 and x = 1.
The functions will intersect at y = -2 and y = 1.
Both functions will have y-intercepts at 2 and 1.
Both functions will have x-intercepts at -2 and 1.

Answers

Answer:

The correct option is;

The function will intersect at x = -2 and x = 1

Step-by-step explanation:

The question parameters are

The functions in the question are f(x) and g(x)

The solution to the equation f(x) = g(x) are -2, and 1

Given that the equations, f(x) and g(x), are both given in values of x, their solution will be the x values that satisfies both functions

Therefore, the functions will intersect (have the same values of f(x) and g(x)) at the points of the solutions, which are given as x = -2, and x = 1

The statement that should be true is the function will intersect at x = -2 and x = 1.

Given that,

The solutions to the equation f(x) = g(x) are -2 and 1. If f and g are graphed on the same coordinate plane.

Based on the above information, the following information should be considered:

As the solutions represent x values that satisfied the both functions. Also, the functions should intersect that contains the same value i.e. x = -2 and x = 1.

Therefore, we can conclude that the first option is correct.

a triangle has side lengths of 14, 23, and 27. Is it a right angle ?

Answers

Answer:

No, it is not

Step-by-step explanation:

Here, we want to check if the lenghts given is that of a right angle triangle

For a right angle triangle, the square of the hypotenuse is equal to the sum of the squares of the two other sides

The hypotenuse represents the longest side

So 27^2 = 14^2 + 23^2

The difference between these is 4, and as such the triangle is not a right angled

Which is an equivalent equation solved for the slope, m? m = yx + b m = m equals StartFraction y minus b Over x EndFraction. m = m equals StartFraction y Over x EndFraction minus b. – b m = y – m equals y minus StartFraction b Over x EndFraction.

Answers

Answer:

m equals StartFraction y minus b Over x EndFraction

Step-by-step explanation:

The standard equation of a line is expressed as;

y = MX+b where;

m is the slope

cmb is the intercept

We are to get the equivalent expression for finding the slope.

Make m the subject of the formula to get this as shown;

From the equation;

y =MX+b

Subtract c from both sides;

y-b = MX+b-b

MX = y-b

Divide through by x;

mx/x = (y-b)/x

m = (y-b)/x

Heme the required expression is m = (y-b)/x OR m equals StartFraction y minus b Over x EndFraction

Jamal hiked on two trails. The first trail was 8 1 3 miles long, and the second trail was 1 3 5 times as long as the first trail. How many miles did Jamal hike? Enter your answer as a mixed number in simplest form.

Answers

Answer:Total distance( miles ) covered by Jamal =21 2/3 miles

Step-by-step explanation:

Step 1

first trail = 8 1/3 miles long

2nd trail = 1 3/5 times as long as the first

Therefore the  distance walked in the  2nd trail is  1 3/5  x 8 1/3

changing to improper fraction and solving  

=8/5 x 25/3= 40/3

The distance hiked by Jamal in the second trail = 40/3=13 1/3

Step 2

Total distance( miles ) covered by Jamal = first trail +2nd trail

= 8 1/3 + 13 1/3 =21 2/3 miles

Answer:

21 2/3 miles

Step-by-step explanation:

First trail = 8 1/3 miles long

Second trail = 1 3/5 times as long as the first trail

= 1 3/5 × 8 1/3

= 8/5 × 25/3

= 40 / 3

= 13 1/3 miles

How many miles did Jamal hike?

Total miles hiked = First trail + Second trail

= 8 1/3 miles + 13 1/3 miles

= 25/3 + 40/3

= 25+40/3

= 65/3

= 21 2/3 miles

Jamal hiked 21 2/3 miles
